GENERAL INFORMATION
All models 8 ~ 25 tons are shipped as separate
condensing unit and evaporator section modules. The
5 ton models are shipped as factory-charged unitized
packages. All models are designed for freestanding
mounting on the floor, or on a field fabricated
structural steel stand. All models can be ordered in
either top or front fan discharge.
The 5 ton model utilizes a single compressor. All 8
through 25 ton models are dual compressor units with
two independent refrigerant circuits. The 8 ~ 25 ton
models require field connection and charging of the
refrigerant circuits. The 8 ~ 25 ton models are shipped
with a nitrogen holding charge only. Refer to ‘Start-Up
and Operation’ section for charge information.
All units come standard with a microprocessor control
board with safety controls and troubleshooting LED
(refer to ‘Microprocessor’ section).
Units will operate reliably at outdoor ambient down to
50F. In applications requiring operation below this
temperature, a low ambient damper accessory is
available. The damper installs on the condenser air
discharge, and allows operation to 0 F ambient.
ONLY QUALIFIED PERSONNEL SHOULD
PERFORM INSTALLATION AND SERVICE
OF THIS EQUIPMENT.
PRE-INSTALLATION INSPECTION OF EQUIPMENT
All units are factory tested to ensure safe operation
and quality assembly. Units are packaged and sealed
on shipping skids and shipped in first class condition.
Torn and broken packaging, scratched or dented
panels should be reported to carrier immediately.
Internal inspection of all units should be performed
prior to installation. Remove all access doors and
check for visual defects that can occur during
transport. Any problems found internally should be
reported to carrier and manufacturer immediately.
Refrigerant circuit should be checked to ensure no
leaks have occurred during shipment. Install gauge
set to high and low pressure ports to confirm pressure
has been maintained and no leaks have occurred
during shipment. Repair any damage prior to
installation to ensure safe operation.

UNIT MOUNTING
The 5 ton model is shipped as a fully assembled
integral package. The 8 ~ 25 ton models are shipped
in two pieces - a separate condensing unit and
evaporator module - which are intended for assembly
into a freestanding vertical package on site. The unit
is not designed for remote condenser / evaporator
installation and must be installed as a packaged
system. Installation or modification of the unit that is
not described in this manual is not factory
recommended nor is it factory supported. User is
responsible for any damage that as a result may
occur.
Flanges for all duct connections, corner securing
brackets, and refrigerant tubing couplings are shipped
in the condensing section of the unit for field
installation. Duct flanges for evaporator return are
incorporated into the filter rack.
Floor mounted units should be secured on a solid,
level pad or sturdy stand. The base of the unit should
be approximately 6 inches higher than the lower edge
of the wall opening. This height will allow the
condenser air ducts to be pitched away from the unit,
offering protection from rain water entering the base
pan (refer to typical installation diagram on Page 4).
The use of an isolating rubber sheet is recommended
to reduce vibration and noise transmission. Ensure
that the entire base is continuously supported. Unit
may be pitched slightly to ensure efficient drainage of
condensate.
Ensure that entire base is continuously
supported. DO NOT support unit at
corner points only!
EVAPORATOR / CONDENSER ASSEMBLY
ASSEMBLY OF SPLIT UNITS (8 - 25 TON MODELS)
- Place the condensing section in the required
location.
- Carefully position the evaporator section atop the
condensing section. Align all sides, the evaporator
motor wire routing hole, and the refrigerant line
routing holes.
- Install the securing brackets at all four corners, on
the evaporator/condenser separation joint.
Securing Corner Bracket
- Units are provided with couplings to mate
refrigerant piping between condenser and
evaporator section. Unit with Hot Gas Bypass
option will be provided with additional copper
couplings for the HGBP piping. Remove shipping
bracket securing spun copper ends in the
condenser, this can be discarded and is not
required.
- Cut off spun copper ends on each refrigerant pipe
in evaporator and condenser. Cut pipe to
appropriate length to fit on couplings. Ensure
circuit 1 from condenser connects to circuit 1
piping in evaporator, follow same procedure for
circuit 2. Do not cross circuits.
- Follow common A/C service practices by brazing
copper couplings to refrigerant pipe using a flow
of nitrogen gas (max. 1 psi) through the refrigerant
piping to minimize contamination to internal
piping. Otherwise damage to unit refrigeration
components may occur. Use the service gauge
ports for this procedure to introduce nitrogen flow.
Once complete pressure test with nitrogen (500
psig).
- Evacuate each circuit to at least 350 microns. If
gauge pressure rises above 500 microns in one
minute, evacuation is incomplete or the system
has a leak.
- Charge circuit(s) to the value indicated on the unit
nameplate or see section ‘Start-Up and
Operation’.
Corner Bracket

HGBP Shown)
Do not cross circuits when brazing
refrigerant piping between sections.
SEPARATION OF UNITS - (DSV060B MODEL)
If separation of units is required to pass through
doorways, elevators. Unit is not designed and not
certified to be installed as a remote condenser and
evaporator.
- Reclaim the entire refrigerant charge from each
compressor circuit.
- Disconnect the evaporator motor high voltage
wires. Pull all wiring into the evaporator
compartment. Remove bushing/clamp from
routing hole for evaporator motor wiring.
- Cut and remove sections of all liquid and suction
refrigerant lines. Make two cuts in each line,
approximately 6 inches above and below the
evaporator floor/condenser roof.
Use a TUBING CUTTER ONLY - do not
use a hacksaw to cut refrigerant tubing
otherwise serious damage can occur
to refrigeration system!
- Remove corner securing brackets from the
outside corners of the cabinet, at the joint line
between the evaporator and condenser sections.
- Remove the evaporator section.
- Refer to ‘Assembly of Split Units’ for assembly
instructions.
CONDENSATE TRAP
Unit requires a field installed external condensate trap
otherwise without a trap condensate can be thrown
into the air stream, cause water overflow resulting in
unit and property damage. This system must be
trapped according to a negative pressure (draw-
through) system. Use dimensions given below.
Adhere to local Codes for piping external trap and
condensate.
Example: Trapping a system up to 2” External static
pressure
A= (1” for each 1” of maximum negative static
pressure)) + 1”

DUCTWORK
When installing ductwork, adhere to local Codes.
Minimize duct runs and avoid abrupt changes in
direction where possible. Allow ample access space
for servicing of the coils and changing of filters.
Perform regular maintenance on ducts to increase unit
life, maintain efficient operation, and reduce
accumulation of explosive dust. Refer to blower
performance charts, and engineer duct runs and
accessory pressure drop so as not to exceed
maximum external static values. Ensure continuous
running condenser intake ambient air temperature do
not exceed 115
o
F. The condenser exhaust should
discharge into an open area to prevent short cycling of
hot exhaust condenser air with the condenser intake.
Louver sizing guidelines
One of the key issues in obtaining optimum
performance from indoor air-conditioners is the proper
selection of the condenser intake and discharge
louvers. Unlike outdoor air cooled units, which intake
and discharge their cooling virtually unrestricted,
indoor units must overcome the resistance of grilles or
louvers at the outside wall - plus the restriction of any
interconnecting ductwork.
Our indoor air cooled air-conditioners are designed to
accommodate the external static pressure loss
associated with properly sized louvers of the "storm
proof” type. This type of louver typically has a free
area approximately 40-45% of the actual louver size.
To determine the free area required for any given unit,
adhere to the following guidelines:
- Size condenser air intakes for 350-600
feet/minute nominal velocity (Maximum
recommended 700 feet/minute)
- Size condenser air discharge for 1,200-1,500 feet
/minute nominal velocity (Maximum recommended
1,700 feet/minute)
The use of louvers with higher velocities than above
may be employed, at the discretion of the
engineer/installer, provided that the total air pressure
drop does not exceed the capability of the condenser
fan and motor. The use of low restriction louvers with
shallow blade angles can allow higher face velocities
without excessive static pressure loss.
Exceeding the static pressure capability of the
condenser fan will result in insufficient condenser air
volume. This will cause a loss in system capacity, and
may cause compressor shut-down during high
ambient periods. (Installation of an oversize
condenser motor/drive, where applicable, may be
considered in such cases.)
(As a general rule, these velocities will require an
intake louver sized approximately 1.25 to 1.5 times
the dimensions of the duct connection on the unit, and
a discharge louver sized approximately 1.5 to 2 times
the duct connection dimensions.)
Use only louver sections that provide different
deflection angles for air discharge and air intake,
to ensure the unit does not short circuit. Protect
the unit from weather conditions (rain, snow) entering
through the condenser air intake. All outdoor air
ducts should pitch away from the unit, toward the
outside wall. Connect all ducts to unit with canvas
section duct connectors or choose another suitable
noise and vibration absorbing device.
The Manufacturer will not accept any
liability resulting from incorrect instal-
lation of this equipment. Follow instal-
lation instructions carefully.
VARIABLE FREQUENCY DRIVE (VFD)
Optional VFD controller for the evaporator fan is
available on the 10 to 25 ton models. Mounted in the
in the evaporator module section, the VFD allows the
operator to set the duct static. The VFD will control the
frequency (speed) of the evaporator fan motor in order
to meet the desired supply duct static set point. For
reliable unit operation unit must have a factory
installed Hot Gas Bypass circuit on refrigeration circuit
# 1.
The unit does not carry a failsafe
circuit to bypass the VFD and run
the evaporator fan in the event of a
VFD malfunction.
VFD is factory mounted and wired. The installer must
field provide and install two sensor tubing lines
complete with static pressure probes. Installer is
required to field wire fan power wiring between
evaporator and condenser as a result of the unit being
shipped factory split. The power wiring can be found
inside the VFD enclosure, no extra power wiring is
required – sufficient length is provided. The VFD
option does not include a evaporator fan bypass
circuit in case of microdrive failure. Microdrive will
need to be replaced to re-activate unit. In case of
VFD failure the evaporator fan will stop running
however unit compressors will continue to run until a
low pressure safety trip is activated.

VFD Input/Output
Note: Jumper is required between contacts 10 & 11
HOT GAS BYPASS (HGBP)
Optional HGBP on the lead compressor circuit (circuit
#1) meters flow of compressor discharge hot gas to
the system low side in order to balance the system
capacity to the space load requirement. HGBP is
factory installed using an adjustable hot gas regulator.
The bypassed hot gas from the compressor is
discharged to the evaporator inlet (i.e.: between the
TX valve and distributor) via a Tee connection.
Adjusting HGBP set point
The desired coil suction pressure or coil temperature
when the HGBP valve opens is selectable by
adjusting the screw on the HGBP valve. To set the
load run the unit and cool down the evaporator coil by
either shutting the fans or by blocking the airflow until
the suction pressure drops at least 5psi below the
desired evaporator coil setpoint. The next step is to
allow the pressure to be raised by the bypassed gas,
the screw spring adjustment can be set until the
HGBP valve closes at the desired set point.
The pressure of the evaporator coil is set to maintain
an evaporator coil temperature above the point where
frost and coil freeze up could form.
AIR SIDE ECONOMIZER
Optional air side economizer mixing box is designed
to attach the return air side of the evaporator. Mixing
comes with low-leakage opposed blade dampers.
Economizer is used to provide ventilation and free
cooling for the JCI DSV series of vertical air handlers.
Economizer setup is done through the LCD keypad
display locating on the economizer control module
mounted on the mixing box. Access to the mixing box
is required.
The factory supplied economizer includes:
economizer module, mixing box, actuator, enthalpy
sensor, temperature sensor, dampers, and wiring
harness. Refer to Appendix C for economizer
electrical wiring schematics.
SEQUENCE OF OPERATION
High enthalpy sequence
Enthalpy sensor should be located in the outdoor air
duct. When the outside air enthalpy exceeds the
enthalpy set-point, the economizer module Y1-In and
Y1-Out terminals are closed and economizer will be
forced into the minimum damper position setting. The
DSV unit’s microprocessor board will control
mechanical cooling requirements.
Low enthalpy sequence
When the outside air enthalpy is below the enthalpy
set-point, economizer module Y1-In and Y1-Out
terminals are opened and free cooling is activated.
The JCI unit’s microprocessor board turns off
compressor operation.
Damper Modulation
The temperature sensor should be located in the
supply discharge air duct. Locating the sensor in the
discharge air provides effective 'low-limit' sensing and
control. The outside-air damper remains at minimum
position if the discharge air temperature is below 50
0
F
or 10
0
C. If the discharge air temperature is between
50
0
to 56
0
F (10
0
to 13.3
0
C) the outside air damper
will modulate between minimum position and fully
open. Above 56
0
F (13.3

C) the outside air damper
will remain in the fully open position.

LOW AMBIENT DAMPER INSTALLATION
If unit operation is required at outdoor ambient below
50 F, the optional Low Ambient Damper kit should be
installed to maintain acceptable condensing pressure.
The damper is installed directly onto the intake duct
connection as illustrated. The damper position is
determined by refrigerant pressure. A direct-coupled
electric damper actuator motor drives the damper
open or closed, depending on the output signal from a
proportional pressure control module. A pressure
transducer senses the high-side refrigerant pressure,
through a service access port, located on the liquid
refrigerant line leaving the condenser. The pressure
controller, complete with terminal connection blocks
for wiring, is attached to a field-installed mounting
bracket. Appropriate mounting hardware for the
pressure control module and the damper actuator
motor are provided with the kit. A routing hole is
provided in the condenser corner panel, near the
actuator mounting location, to allow installation of the
plenum-rated cable between the motor and the control
module.
On dual compressor units, the pressure
transducer MUST be connected to the #1
circuit liquid line fitting. Connection to
the second stage refrigerant circuit will
result in system malfunction.
For detailed installation instructions, refer to the
supplementary ‘Low Ambient Damper Kit’
installation instructions.

EVAPORATOR BLOWER DISCHARGE
CONVERSION
All models can be factory ordered with either front or
top fan discharge.
Procedure for converting the fan discharge is similar
on all models. Original drive belts will need to be
replaced, see ‘Drive Belt’ section for alternate belt
information.
- Remove the panel attachment screws on the
alternate location access panel. Remove the
panel and set aside.
- Remove blower drive belt on all models with
base mounted motors.
- Remove the panel attachments screws on the
blower mounting panel. Do not remove fasteners
securing blowers to panel! The blowers are to
remain attached to the mounting panel at all
times.
- Carefully remove the blower panel assembly
from the evaporator cabinet. Do not allow blower
housings to contact the evaporator coil during the
removal. On some models, the housing(s) will
have to be "rotated" to exit through the panel
opening.
- Interchange the blower panel assembly with the
position of the alternate access panel. Exercise
care in locating the panel. Do not allow blower
housings to contact the evaporator coil. Install
the attachment screws and tighten securely.
- Install the blank access panel into the remaining
evaporator opening. Fasten securely.
- Install new drive belts.
- Adjust drive belts to appropriate tension. Test run
blower and observe operation for unusual
sounds or vibration.
ELECTRICAL WIRING
Follow local electrical codes when making electrical
connections. Units are completely factory wired for
normal supply voltages (ie.208-230, 460,
575V/3Ph/60Hz) Confirm unit specifications by
checking unit data plate. All electrical components are
accessible through an independent electrical panel
located on the "front" face of the condensing section.
The electrical control boxes are located behind outer
access panels. The condenser section electrical cover
is installed with wiring diagrams on the inside, which
must be opened to be read.
Ensure evaporator motor rotation is
correct upon unit start-up. Switch any
two wires at contactor if blower rotation
is not correct.
DISCONNECT AND LOCK OUT POWER
WHEN SERVICING UNIT. UNIT MAY
START AUTOMATICALLY IF POWER IS
NOT DISCONNECTED. FAILURE TO DO
SO MAY RESULT IN PERSONAL IN-
JURY OR DEATH DUE TO ELECTRICAL
SHOCK.
If canvas flexible joints are used on ductwork, install a
ground wire to the ductwork as well.
IMPORTANT: All wiring must comply
with applicable local and national codes
(NEC). Type and location of disconnect
switches must comply with all
applicable codes.
For low voltage thermostat wiring, 18 gauge wire may
be used for up to 50 feet lengths. Low voltage runs up
to 125 feet require 16 gauge wire.

BLOWER SPEED ADJUSTMENT
The blower speed can be adjusted to increase or decrease the unit CFM for non-VFD units. The RPM of the
supply air and condenser air blowers will depend on the required CFM, and the static resistances of both the
supply/discharge and the return/intake duct systems.
An air balance should be done after installation to verify air flow and static. Adjustments to drive may be required.
Only operate unit in the regions defined by the fan tables. Units can be ordered with oversized motors and/or
drive kits for high static requirements.
Units with oversized motors or oversized drive kits are designed to operate in the shaded
region of the fan table otherwise motor amp draw will exceed overload setting resulting in
overload trips and possible damage to unit. Refer to fan tables for recommended operating
range of standard and oversized motors and drive kits.
The RPM for the blowers can be determined from the blower performance tables. Adjustment of blower speed is
accomplished as follows:
1) Loosen belt tension by moving motor towards the blower shaft via the adjustable mounting.
2) Loosen the setscrew in the adjustable motor pulley flange. Remove external key on pulleys 4 in. diameter and
larger.
3) Blower speed will increase when moveable flange is adjusted towards the fixed flange (closed). Blower speed
will decrease when the moveable flange is adjusted away from the fixed flange (opened). Pulleys are
adjustable only in half-turn increments. Do not open pulley more than five full turns for "4L" and "A" belts, or
six full turns for "B" belts.
4) Once the pulley has been opened/closed the appropriate number of turns, replace the external key and
tighten the adjustment setscrew. Proper torque is 110-130 in.-lbs.
5) Install drive belt and adjust motor mount to tension belt (see page 20: MAINTENANCE/SERVICE for further
information).
