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.

DSH Horizontal Units (B/C Style)
1. Attach the two long, horizontal anges from the
LADK low ambient damper kit using the original
holes and screws. These flanges reduce the intake
opening height to match the damper dimensions.
2. Re-attach one of the original vertical anges as
close as possible to the edge of the corner post
(approximately 1/8 inch from corner post's edge).

SECTION 1 - INSTALLATION
When damper blades are fully open, en-
sure they do not contact the unit.
LD26854 LD26855
FIGURE 2 - HORIZONTAL UNIT DAMPER
3. Position the damper casing between the two hori-
zontal ange surfaces, and butt the damper's drive
end against the vertical ange at the unit's cor-
ner. Ensure that the damper is orientated with the
drive shaft at the top of unit (see Figure 2 on page
8).
4. Position the damper blades to fully open and
check that there is no interference with unit. If the
damper blades contact the unit, adjust the damper
slightly away from the unit.
5. Secure the damper using the self-drilling screws
provided. Drive the screws through the holes in
the anges and into the metal damper casing.
6. Attach the remaining vertical ange opposite the
drive end of the casing.
7. Ensure that the damper assembly rotates freely,
with little or no resistance, by rotating the drive
shaft by hand.
DSV Vertical Units (B/C Style)
1. Locate the pilot holes at the condenser exhaust,
and line up the two vertical and two horizontal
duct anges accordingly. The VADK low ambi-
ent damper kit includes the factory-supplied duct
anges.
2. Secure the anges using self-drilling sheet metal
screws. Ensure the horizontal anges are ush
with the condenser exhaust opening.
3. Position the damper casing inside the anges and
secure with screws (see Figure 3 on page 9).
4. Position the damper blades to fully open and
check that there is no interference with the unit.
If the damper blades contact the unit, adjust the
damper slightly away from the unit.
5. Secure the damper using the self-drilling screws
provided. Drive the screws through the holes in
the anges and into the metal damper casing.
6. Attach the remaining vertical ange opposite the
drive end of the casing.
7. Ensure that the damper assembly rotates freely,
with little or no resistance, by rotating the drive
shaft by hand.

FIGURE 3 - VERTICAL UNIT DAMPER
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).
