Installation of cabinet/wall sleeve for thick walls require spe-

cial consideration. Table 1 should be used to determine the

maximum wall thickness allowed for standard cabinet wall

sleeve. For thicker walls, cabinet/wall sleeve extensions are

available from your representative. Refer to pages 8 for proper

installation of cabinet/wall sleeve extensions.

Cabinet/wall sleeve installation in thick walls is similar to

frame and brick installation. The wall sleeve is not intended to

replace the lintel. Install as follows:

1. Clean the opening of all debris that may interfere with

installation.

2. If the unit is to be supplied with a subbase, refer to page

9 for installation procedure. Install subbase before install-

ing cabinet/wall sleeve.

3. If the optional drain kit is to be employed, refer to page

10 before proceeding.

4. If wall thickness exceeds dimensions shown in table 1 a

cabinet/wall sleeve extension must be used. Install the

extension as described on page 8. Once the extension is

attached to the cabinet/wall sleeve, place a thin pad of

soft mortar on bottom of the opening and slide in the wall/

sleeve extension assembly. Be sure to recess the wall/

sleeve enough to accommodate outside louver. This re-

cess is

"(9.5mm) for stamped louvers and 1

"(32mm)

for architecture louvers. Louvers should be flush to exte-

rior surface when completed. Note : Do not recess the

sleeve if using the external drain kit - see pg. 10.

5. Level cabinet /wall sleeve in both directions and secure

by anchoring with appropriate fasteners, (as shown in fig-

ure C page 8), or drill additional holes as required to se-

cure firmly. Caution: Do not drill holes in the subbase

of the cabinet/wall sleeve. Where a subbase is used,

secure wall sleeve to subbase with clips provided.

The standard cabinet/wall sleeve will accommodate a

maximum wall thickness described in table 1, page 7. For

thicker walls, cabinet/wall sleeve extensions are available

from your local representative. When it is supplied by the

representative, it is treated for maximum corrosion resis-

tance and matched to exact size of the standard wall/

sleeve. Be sure to provide air splitters to prevent recircula-

tion of condenser air. Air splitters should be placed in the

wall sleeve as shown in figure A. It is important that spacing

of the air splitters match exactly those dimensions shown in

figure A.

Installation

Wall sleeve extensions are shipped in a separate carton and

tagged to match the proper unit. Be sure to check tagging

of the extension against that of the unit. Install the wall

sleeve extension as follows:

1. Position the extension with standard cabinet/wall sleeve

so proper alignment with drain and mounting holes is

achieved.

2. Place a bead of caulk around the perimeter of the wall

sleeve and another bead around the mating side of the

wall sleeve extension so that the joint is watertight. Be

sure to use a resilient caulking such as silicone.

3. Assemble the wall sleeve extension to the wall sleeve.

Clean out weep holes to assure proper drainage.

4. Attach indoor drain kit (if used) according to the

instructions on page 10. Outdoor drain kits must be

installed after wall sleeve is in place.

5. Continue wall sleeve installation according to instruc-

tion #4 on page 7.

Louver Frame

Louver frames should be used for panel wall and thin wall

applications to assure positive anchoring to the wall. Recess

the cabinet/wall sleeve so that the louver is flush with the out-

side of the building. Place louver frame around cabinet/wall

sleeve as shown in figure B. Caution: Do not to drill holes in

the bottom of the wall sleeve. Secure angles at side and top

of walls.

Anchoring

Anchoring the cabinet/wall sleeve in the opening is accom-

plished as shown in figure C. Caution: Do not to drill holes

in the bottom as it will cause leaks. It is recommended that

rubber isolation washers be used with the fasteners to mini-

mize sound transmission from the equipment to the wall, at

the point of contact.

Electric Subbase

An electrical subbase is optional for all 208V and 230V units.

A subbase is standard for all 265V units. The standard is avail-

able with 3". (76mm) or 4" (102mm) heights. The subbase con-

tains leveling legs for adjustment of up to 1" (25mm) addi-

tional height. All subbases are factory supplied.

Installation

1. If the minimum depth subbase is required, discard the side

extension pieces.

2. If more than the minimum depth is required, determine the

depth of the side extension pieces desired and break at

proper score - line. Insert the extension pieces into the

front assembly and secure with two short black screws at

each side.

3. Insert leveling bolts into subbase bottom flange. Four (4)

bolts will be needed if side extensions are used. Only two

(2) bolts are required if side extensions are not used.

4. Place the subbase on the floor and align its center line

with the center line of the wall opening. Do not fasten the

subbase to the floor. Attach the subbase to the cabinet/

wall sleeve using the clips provided with the subbase.

5. The wiring should be roughed in and the conduit connected

to the subbase junction box. Complete the installation by

wiring the receptacle to the incoming power supply.

Hydronic Subbase

A subbase is supplied as standard with all hydronic units. This

subbase measures 8" (203mm) in height and includes the

hydronic heating coil. Refer to IM Bulletin 419 for installation

details. In addition, rough in supply and return piping.

Electrical and plumbing rough-in can be done through the back

of the hydronic heat section or through the openings provided

in the bottom of the subbase. The finished piping can be done

now or later.

Note: Heat pump models will generate condensate during

the heat season. To ensure that no condensation will run

down the building, always use a drain kit with heat pump.

Condensate drain kits can be supplied for internal and

external applications. Figure 14 illustrates the installation of

the indoor drain kit. The indoor drain kit should be installed

before placing the cabinet/wall sleeve into the opening. Install

as follows:

1. Locate the drain so that it will be on the room side of the

wall when the cabinet/wall sleeve is installed.

2. Drill a

" (13mm) diameter hole in the base of the cabi-

net/wall sleeve for the drain line.

3. Drill two (2)

" (4mm) pilot holes for the mounting screws.

These holes can be located using the drain kit as a pat-

tern.

4. Assemble the drain kit as shown in figure 14 and securely

fasten it to the cabinet/wall sleeve with the screws provided.

5. Slide the cabinet/wall sleeve into the opening and anchor

it into place.

Assembly of the external drain kit should be completed after

the cabinet/wall sleeve has been installed. Note: When using

the external drain kit, the sleeve must be flush or beynd the

outside finished wall - do not recess. Install the external drain

kit as follows:

1. Assemble the drain kit as shown in figure 15.

2. Choose which side of the cabinet/wall sleeve the drain kit

is to be installed.

1 Remove louver and mounting hardware from the ship-

ping carton.

2 Remove temporary cardboard weather panel from

cabinet/wall sleeve.

3. Make a temporary handle by looping a piece of flexible

wire or heavy cord through the louver. This enables the

installer to keep a firm grasp on the louver when installing

from inside the room.

Proper installation of the heating/cooling chassis is extremely

important to the proper operation of the unit. Whether the wall

sleeve has been separately shipped or shipped with the

chassis, proper installation is as follows:

1. Remove shipping carton and inspect for any shipping

damage. Report any found to the carrier.

2. Save shipping carton to cover installed conditioner until

construction is complete.

3. Check nameplate data on chassis to insure that the cor-

rect job site distribution has been made with respect to

heating/cooling capacities. Generally, corner rooms re-

quire larger capacities.

4. Set front panel and air filter aside.

5. Remove chassis from carton by pulling evenly on sub-

stantial portion of unit. Caution: Do not pull on Evapo-

rator Top Panel.

6. If wall sleeve has been previously installed, remove

temporary cardboard weather panel.

7 If louver has been previously installed, remove temporary

cardboard weather panel.

8 Place Tinnerman clips on wall sleeve. Clips and mount-

ing screws enclosed in a bag attached to the inside chas-

sis side panel.

9. Rotate fans to be sure they are free of obstruction.

10. Check all fasteners to make certain they did not loosen

during shipment. Do not loosen nuts holding down com-

pressor; they are factory installed.

11. Do not lubricate motors before start-up. Motors are fac-

tory lubricated. Consult “Scheduled Maintenance” sec-

tion on page 13 for lubrication instructions.

12. Check all copper tubing and capillaries for proper clear-

ance so they will not hit or rub during operation.

13. Slide chassis into wall sleeve until firmly seated against

weather seals. Caution: Do not push on coil surface,

control box cover or fan scroll. Make sure tubing does

not catch when inserting chassis.

14. Secure the chassis in the cabinet/wall sleeve with four (4)

screws packaged with the Tinnerman clips.

15. Plug electrical cord into receptacle. Excess cord for 208V

and 230V units should be coiled neatly and stored in the

conditioner. Attach plug/cord cover to front face of sub-

base on 265V.

16. Set the manual damper operator in open or closed posi-

tion as desired. On units equipped With the optional elec-

4. Angle the louver through the opening at the rear of the

wall box, then pull the louver back to the wall sleeve flange

so that the louver studs pass through the holes in the

flange.

5. Attach washers and nuts and secure louver in place.

6. If the heating/cooling chassis is not to be immediately

installed, replace the weather panel.

tric fresh air damper, set the “auto/off” switch to the de-

sired position. In “auto,” the damper is open when ever

the fan motor is running. The auto/off' switch is located

on the bottom front face of the control box.

17. Check the “Override/Normal” dial (heat pump only) lo-

cated on the top of the unit to the left of the controls. For

normal heat pump operation, position the dial clockwise,

to “Normal”. Only the electric heater will operate when

dial is in “Override” position,(maximum counter clockwise).

18. Set fan cycle switch (located on the lower front face of

the control box) for constant or cycling indoor fan. With

the switch in the “cycle” position, the indoor fan will shut

off when the thermostat shuts off heating or cooling.

19. Set the temperature limiting feature to the desired range

of thermostat operations. As shipped, the range is 65°F

to 85°F.

20. Replace the air filter and front panel.

21. For hydronic units:

a. Route the two low voltage valve wires, with Molex con-

nection, through the opening provided in the subbase and

connect to valve.

b. Connect short power cord from the chassis to the recep-

tacle in the subbase heat section.

c. Relocate thermostat bulb to bracket located in the sub-

base. Refer to IM419 which is provided with the hydronic

subbase.

d. Replace filter and louvered subbase front panel.

22. When installing the E vintage chassis in older wall sleeves,

bend the Sheet metal flange at the rear of the wall sleeve

rails to allow full insertion of the chassis.

All wiring should be done in accordance with all local and

National Electrical Code requirements. The 2-Motor unit has

a multitap heater so the kw is determined by the field installed

power cord selection. Refer to it & the data plate for proper

overcurrent protection. The 1 motor unit does not have a

multitap heater and the power cord is factory installed. The

conditioners are supplied as follows:

Electrical Heating Unit

1. 208V and 230V models are supplied with a power cord

which will exit from beneath the conditioner on the con-

trol side. The cord has a usable length of 72" (1829mm)

from where it exits the conditioner. The use of an exten-

sion cord is not recommended. Time delay fusses are

recommended to avoid nuisance tripping. The receptacle

is generally mounted beneath the conditioner, on or re-

cessed in the wall so that it is concealed by the condi-

tioner over hang. The space under the conditioner must

be at least 3" (76mm) high.

2. An electrical subbase is available for 208V and 230V units

and contains a junction box for a field mounted recep-

tacle All electrical connections are made within the sub-

A temperature limiting device is furnished as a standard

to allow the owner to set the minimum and/or maximum

temperature selections. Adjust this device as follows:

1 Remove the two screws that secure the lower ends of

the front panel and remove the front panel from the unit.

2 Pull off the control knobs and remove polycarbonate mem-

brane overlay with metal plate.

3. Move the 2 screws that stop the “pointer” to the desired

location.

Initial start-up of the Incremental

conditioners by experienced

personnel is usually the responsibility of the installing con-

tractor. This start-up consist of inspecting and operating the

equipment for all functions at the time of initial installation,

and making necessary adjustments. It also includes demon-

strating its proper operation to the owner or his agent. Note

that unless otherwise specifically agreed to in writing, McQuay

International includes no field labor, start-up service or the

like in the price of its equipment. After the equipment leaves

the factory, it may become damaged or maladjusted during

transpiration or on the job. Sometimes wires are disconnected

accidentally, or fan motors move on their bases due to rough

handling, causing fans to strike. The correction of such condi-

tions is part of start-up.

Before Starting Equipment, Make Certain That:

1. Correct voltage has been supplied to the equipment.

2. The electrical plug from the control box has been inserted

into the receptacle.

During Start-up (applies only to standard equipment):

1. Set manual ventilation damper to Open or Closed posi-

tion as required by owner

2. Select “HIGH HEAT” on the rotary switch. Move thermo-

stat to the extreme heating position (counterclockwise).

4. Replace overlay.

5. Once unit is in operation, rotate knob to maximum heat

and / or maximum cool to check temperature limits. Re-

peat procedure listed above until desired temperature limi-

tations are achieved.

6. Replace front panel and tamper resistant front panel

screws removed in step #1.

base, thus eliminating the need for a wall mounted re-

ceptacle.

The subbase is available in 3" (76mm) or 4' (102mm) height

and can be furnished with factory mounted fused disconnect

option.

3. On all 265V models, an electrical subbase is required.

The chassis is supplied with a “short cord” which is just

long enough to plug into the subbase. A plug / cord cover

is also furnished with the subbase to make the intercon-

necting cord inaccessible, as required by the National

Electrical Code. The conditioner is marked with the mini-

mum circuit ampacity and maximum fuse size.

Hydronic Heating Unit

1. All hydronic units are supplied with a subbase. The sub-

base is 8

⁄

" (210mm) high and houses both the hydronic

heating coil and electrical connections.

2. A short cord is furnished to be plugged into the top of the

subbase. A plug/cord cover is not furnished with these

units.

3. A fussed disconnect option is available and comes

furnished factory mounted.

If the CYCLE/CONSTANT switch is placed in the “CYCLE”

position, heat and indoor fan motor should cycle on and

off as the thermostat requires. We suggest leaving this

switch in “CONSTANT”, to provide better overall tempera-

ture control. Select “LOW HEAT”, on the rotary switch;

fan should change to low speed . If it is a heat pump unit,

electric resistance heat will be delivered at outdoor tem-

peratures less than 30°F (1.6°C). Outdoor fan should be

on whenever compressor operates.

3. Select “HIGH COOL”. Move thermostat to the extreme

cooling position (clockwise). Compressor and indoor fan

motor should cycle on and off as the thermostat requires.

Select LOW COOL; fan

should change to lower speed. Outdoor fan should be on

whenever compressor operates.

4. Select FAN Position. Indoor fan should operate at high

speed or low speed as selected. Neither heater nor

compressor should continue to operate.

5. Select Stop Position. Fan should stop, and neither heater

nor compressor should continue to operate.

Note: Direction of conditioner air may be adjusted by reposi-

tioning the discharge grille to change airflow pattern in

a room. The building superintendent or assistant man-

ager should be requested to make any changes.

Units that are furnished with remote mounted thermostats

should be wired as shown in Figure 17. Other considerations

for this arrangement are as follows:

1. When wiring the low voltage plug and receptacle discon-

nect, provide enough wire to move harness out of the

way for chassis removal

2. If subbase is used, a small hole must be drilled and

grommeted in the subbase front to allow passage of the

low voltage wires.

3. If slave units are to be employed, connects shown in Fig-

ure 17. With this arrangement, the loop between termi-

nals N2 and N4 of the slave unit must be severed. The

standard master transformer handles 10 VA power draw

and each slave unit draws 5VA. If more than one slave

unit is used, the master transformer must be replaced

with a larger one. The number of slave units that can be

connected is limited to the maximum amperage rating of

the thermostat contacts.

4. When using a programmable wall thermostat, splice into

the jumper going from N2 to N4 of the master unit and

connect it to the common terminal of the thermostat. Refer

to the instructions furnished with the chosen thermostat

to locate the common terminal. Note: It may be neces-

sary to place a larger VA transformer in the unit when

using certain programmable thermostats. Check the VA

draw of the chosen thermostat,

Incremental conditioners are built to last. With proper care,

the unit should provide uninterrupted service for many years.

Scheduled maintenance of this equipment as described bel-

low, is the key to the equipment's longevity.

A. Air filters must be cleaned at regular intervals. Twice an-

nually may be adequate in some areas while twice monthly

may be required in others. Areas with high dirt and lint

content or heavy usage of units require more frequent

filter maintenance than those areas of relatively clean

operating or low usage conditions. Unit malfunction will

occur if air filters are not kept clean. Rinse filter with hot

water and a mild detergent. Let dry and oil lightly to en-

hance dust collecting ability.

B. McQuay recommends that every year the chassis be re-

moved for a thorough checkup. This should be completed

as follows:

1. Unplug unit from power source.

2. Remove front panel.

3. Remove chassis from cabinet and move it to the mainte-

nance department. Replace with spare chassis or weather

plate.

4. Check all seals and Insulation and repair as required.

5. Check all wiring and controls for hazardous conditions.

6. Thoroughly clean discharge grilles.

7. Cover motors and control module with water tight mate-

rial and wash evaporator coil, condenser coil and base

pan using hot water and a mild soap.

Residential and institutional cleaning compounds can cause

permanent damage to the packaged terminal unit. To avoid

damage to unit controls and heat transfer surfaces, do not

spray cleaning compounds onto the discharge grille, return

air opening, or unit controls. Normal cleaning can be accom-

plished by wiping the unit surface with a damp cloth. When

using cleaning compounds on carpets, floors or walls, turn

the unit off to avoid drawing potentially damaging vapors into

the package terminal unit.

8. Clean condensate drain and clear weep holes.

9. Dry equipment thoroughly, especially electric parts and

installation. 10. Clean any rust spots with steel wool and

paint with rust inhibiting paint.

11. Clean insulation or replace if necessary.

12. Check insulation on refrigeration piping and replace if

necessary.

13. Check all fasteners and tighten as required.

14. Clean and oil damper door and linkage.

15. Test run chassis before reinstalling.

An inherent advantage of the Incremental system is that fail-

ure of any part affects only one incremental conditioner and

does not interrupt the operation of the rest of the system. A

further advantage is that a failed part can be quickly and eas-

ily replaced, thus minimizing the inoperative time of the equip-

ment. This is so, however, only if a replacement part is quickly

available. In order to replace a failed part quickly and keep all

incremental conditioners in good operating condition, McQuay

International recommends that at the time incremental condi-

tioners are purchased, owners arrange for a small stock of

replacement parts.

Where an owner carries such a stock, immediate replacement

parts of defective part is possible. The defective part can then

be returned to McQuay International or one its authorized ser-

vice stations. So long as it is still in warranty, it is repaired or

replaced and returned to the owner with out cost for shop

labor and material. Thus, the stock of replacement parts is

constantly replenished. To the right is listed the kinds of parts

which McQuay International recommends to be carried in

Every motor-driven refrigeration system operates on the carnot

cycle. A practical understanding of what goes on at the vari-

ous steps in this cycle can be a big help to the troubleshoot-

ing mechanic. Figure 18 illustrates the refrigeration cycle. The

diagram shows what occurs in each component of a hermeti-

cally sealed system, as used in all McQuay Air Conditioning

equipment. The temperatures shown are typical of what they

might be when the air entering the condenser (outdoor tem-

perature) is 95°F, (350 C) and the temperature of the condi-

tioned space is 80°F (270 C).
