Jobsite Storage

This unit is intended for indoor use

only. To protect the unit from damage

due to the elements, and to prevent

possible IAQ contaminant sources

from growing, the unit should be

stored indoors. If indoor storage is

not possible, the following provisions

for outdoor storage must be met.

1. Place the unit(s) on a dry sur-

face or raise above the ground

to assure adequate air circula-

tion beneath the unit. This is to

assure that no portion of the unit

contacts standing water at any

time.

2. Cover the unit(s) with a water

proof tarp to protect them from

the elements.

3. Make provisions for continu-

ous venting of the covered

units to prevent moisture from

standing on the unit(s) sur-

faces. Wet interior unit insulation

can become an amplification site

for microbial growth (mold) which

has been determined to be a

cause of odors and serious

health related indoor air quality

problems.

4. Store units in the normal UP

orientation. Storing units in this

manner maintains oil in the com-

pressor.

5. Units may be stacked two high.

Pre-installation

Checklist

Jobsite Inspection

Each unit has been inspected, tested

and operated at the factory by pro-

duction and quality associates prior

to being crated for safe transit. How-

ever, rough handling or accidents

can occur resulting in damaged

equipment being delivered. Always

perform the following checks before

accepting a unit:

1. Do not sign the bill of lading

accepting the unit(s) until

inspection has been com-

pleted. Check for damage

promptly after the unit(s) are

unloaded. Once the bill of lading

is signed at the jobsite, the unit(s)

are now the property of the SOLD

TO party and future freight claims

MAY NOT be accepted by the

freight company.

2. Check the unit model numbers

on the bill of lading against

those ordered and received to

assure equipment is AS

ORDERED.

3. Check to assure that the refrig-

erant charge has been retained

during shipment by use of

gauges. Schrader taps are

located and labeled internal to

the cabinet. (See Figure 1).

Figure 1: Schrader location

LOW

IMPORTANT!

After assuring that charge has been retained:

Reinstall schrader caps to assure that refrigerant

leakage does not occur.

Reinstall unit panel using all factory provided

screws.

ance from other mechanical and electrical equipment on three service sides (shown below). This enables

panel removal from the unit for service/maintenance ability.

Uncrate Unit

Remove packaging and inspect the unit. Carefully re-

move the stretch wrap and cardboard pieces. The in-

stallation literature and Torx

®

head tool may be found

on the back of the unit in a clear baggie. Unit has been

tied to skid by (2) shipping brackets.

Inspect Unit

Remove refrigeration panel and inspect the unit. Be

certain the refrigerant tubing has clearance from adja-

cent parts. Verify that the electrical connections are

tight and in-place.

Mounting to Wall

With the chassis still on the subbase, align the unit to

the wall. If unit contains an outside air option, align the

wall cut-out to the subbase outside-air cut-out. Level

the unit per plan requirements. Mark the four mount-

ing locations for wall sleeve mounting to the wall. The

dimensions should fall in line with Step 5.

Remove Chassis

Remove the chassis from the subbase via 6-Torx head

screws. The chassis is attached to both the subbase

and the wall sleeve (see diagram above). To assure

proper alignment, re-install screws 2 and 3 in the final

installation of the unit (Step 11).

Wall Flange

After removing chassis from the subbase, install the

wall flange assembly to the desired wall with the use

of four #10-field provided screws. The wall flange as-

sembly includes four, 1/4-inch in diameter clearance

holes.

Mounting of Disconnect

(circuit breaker-OPTION)

Mounting of the circuit breaker/receptical box should

be made prior to piping and electrical hook-up. This

factory disconnect option is designed to fit inside the

end pocket. Mount the electrical box flush with the

subbase with four, #8-field supplied screws.

Mounting of Disconnect

(receptical box-OPTION)

Mounting of the receptical box should be made prior

to piping and electrical hook-up. This factory discon-

nect option is designed to fit inside the end pocket.

Mount the receptical box 2-inches above the top of the

subbase with four, #8-field supplied screws.

Wiring of Disconnect

(OPTION)

Power wiring to the equipment should be installed per

national and local electric codes by a professional

electrician.

Power wiring to the disconnect may be done at this

time. See the unit’s wiring schematic for field wiring.

The above schematic is for REFERENCE ONLY.
