GENERAL INFORMATION
Before installing this accessory kit, turn
off electrical power to the equipment.
Failure to do so could result in electrical
shock, leading to component damage,
injury, or death.
If DSH/DSV unit operation is required at outdoor air
temperatures (OATs) between 50.0°F and 0.0°F (mini-
mum), install the optional low ambient damper kit to
maintain acceptable condensing pressure.
From the Commission > Standard menu on the Smart
Equipment controller (SEC), ensure the parameter CL-
GOATCUTOUT-EN is set to NO. This enables the unit
to operate when outdoor temperatures are below 45.0°F
(factory default).
In horizontal DSH units, install the damper directly
over the intake duct connection. In vertical DSV units,
install the damper over the exhaust duct connection.
Determine the damper actuator position by the refrig-
erant pressure. Depending on the output signal from a
proportional pressure control module, the direct-cou-
pled, electric damper actuator motor drives the damper
open or closed. A pressure transducer senses the high-
side refrigerant pressure through a service access port
that is located on the liquid refrigerant line leaving the
condenser. The pressure controller panel, complete
with terminal connection blocks for wiring, is attached
to a field-installed mounting bracket.
The low ambient damper kit provides all appropriate
mounting hardware for the pressure control module and
the damper actuator motor. The condenser corner panel
contains a routing hole near the damper actuator's mount-
ing location that enables installation of the plenum-rated
cable between the motor and the C450 controller.
On dual compressor units, the transducer
MUST be connected to the rst stage cir-
cuit liquid line tting. Connection to the
second stage refrigerant circuit can result
in system malfunction.
Prior to securing the damper to the unit,
ensure the damper blades do not interfere
with unit when fully open!
When installing the transducer, observe
all regulations governing the handling
and containment of hazardous or regulat-
ed materials (refrigerants or lubricants).
DAMPER INSTALLATION
FOR ALL DAMPERS: To avoid shipping
damage, the damper rod is recessed inside
damper and must be pulled out.
For damper information, refer to the DSV Installation,
Operation, and Maintenance (IOM) manual (145.29-
IOM3) or DSH IOM manual (145.32-IOM5).
1. Loosen the four nuts as shown in Figure 1 below.
2. Slide out the damper rod approximately 3.5 inch-
es from the damper as shown in Figure 1.
3. Tighten the four nuts as shown in Figure 1.

1. Mount the pressure control panel in the compres-
sor/condenser section immediately behind the
compressor side access panel (see Figure 4 on
page 10 and Figure 5 on page 11). In hori-
zontal DSH units, mount the pressure control pan-
el to the interior base pan. In vertical DSV units,
mount the panel to the base rails. Fasten the panel
bracket to the vertical ange of the interior base
pan (recommended) or to the horizontal surface
of the pan using the provided self-drilling screws.
2. Using the pre-terminated two-wire harness (red
and white) from the kit, connect the pressure con-
trol panel to the microprocessor board's R and C
terminals that are located in the main electrical
panel of the condensing unit. The harness must be
fed through the electrical routing hole.
• On horizontal DSH units, the hole is located
at the intake end of the condenser coil (see
Figure 4 on page 10).
• On vertical DSV units, the hole is located at
the low voltage end of the electrical panel
(see Figure 5 on page 11).
3. Route the harness across the blower section of the
unit. For horizontal DSH units, route the harness
into the back of the electrical panel via the low
voltage entrance hole.
4. Using the self-adhesive mounts provided, secure
the harness. This ensures that the wiring is kept
well clear of the belt-driven blower and motor as-
sembly.
5. On the microprocessor board, connect the red
harness lead to the R terminal and the white har-
ness lead to the C terminal (see Figure 12 on page
15 and Figure 13 on page 16).
6. Within the compressor compartment, secure the
harness to the existing compressor wiring. Route
the terminated ends to the 2-pole terminal block
on the pressure control panel. Attach the termi-
nated harness ends to the appropriate terminals
(red-to-red and white-to-white).

rectly to the liquid refrigerant pressure port. This
port is incorporated into the refrigerant shutoff
valve (as illustrated with DSH single stage units
in Figure 4 on page 10).
On dual compressor units, the transducer
MUST be connected to the rst stage cir-
cuit liquid line tting. Connection to the
second stage refrigerant circuit can result
in system malfunction.
2. Hand thread the transducer onto the pressure port.
Wear gloves for protection. Seat the trans-
ducer as quickly as possible to minimize
release of liquid refrigerant.
3. To avoid damaging the transducer, tighten the
connection using the wrench ats provided
4. The connecting harness for the pressure trans-
ducer is pre-wired to the pressure control panel.
The sensor end of the harness is equipped with a
polarized plug connection. Insert the plug into the

SEQUENCE OF OPERATION: FUNCTIONAL
CHECK
This condensing pressure control package is designed
to maintain a minimum refrigerant liquid pressure of
260 psig, which is sufficient to ensure proper expan-
sion valve operation under all normal conditions. The
electronic proportional control module generates a 0 to
10 VDC output signal based on sensed pressure. This
output signal modulates the condenser air volume, from
0–100%, via an electrically motorized intake damper.
The C450 controller is factory configured for reverse
acting mode. The analog signal output increases as
the sensed pressure drops. Dashed areas in Figure 14
on page 17 show throttling range possibilities from
minimum to maximum.

The control setpoint is factory set at 360 psig with a
100 psi throttling range.
If outdoor air temperature (OAT) and system load re-
sult in a condensing pressure above 360 psig, the output
signal is 0 volts. At a signal voltage of 0, the damper
actuator motor drives the damper 100% open.
At refrigerant pressures below 260 psig, the control
output signal is 10 VDC, driving the damper actuator
100% closed.
In practical operation, the condenser intake damper is
fully closed whenever sensed refrigerant pressure is
below 260 psig. This normally occurs during an ex-
tended system OFF interval, especially during periods
of moderate to low OA temperatures. Upon compres-
sor start, the pressure in the system increases until it
reaches the 260 psig minimum throttling range. The
damper only begins to modulate at pressures above
260 psig, ensuring that the actual operating condensing
pressure is always greater than this minimum value.
