GENERAL
UP Model DW units are either single package cooling
units equipped with optional factory installed electric
heaters, or single package gas-fired central heating
furnaces with cooling unit. Both are designed for out-
door installation on a rooftop or slab.
The units are completely assembled on rigid, perma-
nently attached base rails. All piping, refrigerant
charge, and electrical wiring is factory installed and
tested. The units require electric power, gas connec-
tion, duct connections, installation of combustion air
inlet hood, flue gas outlet hoods and fixed outdoor air
intake damper (units without economizer or motorized
damper option only) at the point of installation.
The supplemental electric heaters have nickel-chrome
elements and utilize single point power connection.
The gas-fired heaters have aluminized-steel (or
optional stainless steel) tubular heat exchangers. The
units have spark ignition with proven pilot. All gas heat-
ers are shipped from the factory equipped for natural
gas use, but can be field converted to L.P./ Propane
with Kit Model # 1NP0440 for single stage and Kit
Model # 1NP0485 for 2 stage.
SAFETY CONSIDERATIONS
Due to system pressure, moving parts and electrical
components, installation and servicing of air condition-
ing equipment can be hazardous. Only qualified,
trained, service personnel should install, repair, main-
tain or service this equipment.
Observe all precautions in the literature, on labels and
tags accompanying the equipment whenever working
on air conditioning equipment. Be sure to follow all
other safety precautions that apply.
Wear safety glasses and work gloves, and follow all
safety codes. Use a quenching cloth and have a fire
extinguisher available for all brazing operations.
INSPECTION
As soon as a unit is received, it should be inspected for
possible damage during transit. If damage is evident,
the extent of the damage should be noted on the car-
rier's freight bill. A separate request for inspection by
the carrier's agent should be made in writing.
FIRE OR EXPLOSION HAZARD
Failure to follow safety warnings exactly could
result in serious injury, death, or property dam-
age.

and 19 for the clearances required for combustible con-
struction, servicing, and proper unit operation.
DUCTWORK
Ductwork should be designed and sized according to
the methods in Manual Q of the Air Conditioning Con-
tractors of America (ACCA).
A closed return duct system shall be used. This shall
not preclude use of economizers or outdoor fresh air
intake. The supply and return air duct connections at
the unit should be made with flexible joints to minimize
noise.
The supply and return air duct systems should be
designed for the CFM and static requirements of the
job. They should NOT be sized to match the dimen-
sions of the duct connections on the unit.
Refer to Figures 10 through 14 for information concern-
ing side and bottom supply and return air duct openings.
NOTE: It is recommended that, in Canada, the outlet
duct be provided with a removable access
panel. It is recommended that this opening be
accessible when the unit is installed in service,
and of a size such that smoke or reflected light
may be observed inside the casing to indicate
the presence of leaks in the heat exchanger.
The cover should be attached in a manner
adequate to prevent leakage.
CONDENSATE DRAIN
Plumbing must conform to local codes. Use a sealing
compound on male pipe threads. Install a condensate
drain line from the 3/4” NPT female connection on the
unit to an open drain.
NOTE: The condensate drain operates in a negative
pressure in the cabinet. The condensate drain
line MUST be trapped to provide proper drain-
age. See Figure 1.
COMPRESSORS
Units are shipped with compressor mountings factory-
adjusted and ready for operation.
Units with scroll compressors have a shipping bracket
which must be removed after the unit is set in place.
See Figure 2.
FILTERS
One-inch or two-inch filters can be supplied with each
unit. Filters must always be installed ahead of the
evaporator coil and must be kept clean or replaced with
same size and type. Dirty filters will reduce the capacity
of the unit and will result in frosted coils or safety shut-
down. Minimum filter area and required sizes are
shown in Physical Data Table 8.
Do not permit overhanging structures or shrubs
to obstruct outdoor air discharge outlet, com-
bustion air inlet or vent outlets.
When fastening ductwork to side duct flanges
on unit, insert screws through duct flanges only.
DO NOT insert screws through casing. Outdoor
ductwork must be insulated and waterproofed.

GAS PIPING
Proper sizing of gas piping depends on the cubic feet
per hour of gas flow required, specific gravity of the gas
and the length of run. “National Fuel Gas Code” Z223.1
(in U.S.A.) or the current Gas Installation Codes CSA-
B149.1 (in Canada) should be followed in all cases
unless superseded by local codes or gas utility require-
ments. Refer to the Pipe Sizing Table 5.
The heating value of the gas may differ with locality.
The value should be checked with the local gas utility.
NOTE: There may be a local gas utility requirement
specifying a minimum diameter for gas piping.
All units require a 1/2” pipe connection at the
entrance fitting.
GAS CONNECTION
The gas supply line can be routed through the knock-
outs located on the front of the unit or through the
opening provided in the unit's base. Refer to Figure 11
to locate these access openings. Typical supply piping
arrangements are shown in Figures 4 and 5. All
shaded items are field-supplied.
If gas supply line is routed through the unit's base
ensure that the burner assembly can be removed for
maintenance without disturbing the supply line. The sup-
ply piping and fittings must lie below the bottom gas
manifold to avoid interference with the burner assembly.
Two grommets are shipped in the blower compartment
(in parts bag taped to the blower housing) of every unit
with gas heat and should be used in the knockouts
when the gas piping penetrates the front of the unit.
After the gas supply piping has been installed, the bot-
tom opening in the unit should be sealed to prevent
water from leaking into the building.
Gas piping recommendations:
1. A drip leg and a ground joint union must be
installed in the gas piping.
2. When required by local codes, a manual shut-off
valve may have to be installed outside of the unit.
3. Use wrought iron or steel pipe for all gas lines. Pipe
compound should be applied sparingly to male
threads only.
4. All piping should be cleaned of dirt and scale by
hammering on the outside of the pipe and blowing
out the loose dirt and scale. Before initial start-up,
be sure that all of the gas lines external to the unit
have been purged of air.
5. The gas supply should be a separate line and
installed in accordance with all safety codes as
prescribed under “Limitations”. After the gas con-
nections have been completed, open the main
shut-off valve admitting normal gas pressure to the
mains. Check all joints for leaks with soap solution
or other material suitable for the purpose. NEVER
USE A FLAME.

dissolve white lead or most standard commer-
cial compounds. Therefore, a special pipe
compound must be applied when wrought iron
or steel pipe is used. Shellac base compounds
such as Gaskolac or Stalastic, and compounds
such as Rectorseal #5, Clyde's or John Crane
may be used.

6. The furnace and its individual manual shut-off
valve must be disconnected from the gas supply
piping system during any pressure testing of that
system at test pressures in excess of 1/2 psig
(3.48kPa).
The furnace must be isolated from the gas supply
piping system by closing its individual manual shut-
off valve during any pressure testing of the gas
supply piping system at test pressures equal to or
less than 1/2 psig (3.48kPa).
7. A 1/8 inch NPT plugged tap, accessible for test
gage connection, must be installed immediately
upstream of the gas supply connection to the fur-
nace.
L.P. UNITS, TANKS AND PIPING
All gas heat units are shipped from the factory
equipped for natural gas use only. The unit may be
converted in the field for use with L.P./propane gas
with accessory kit model number 1NP0440 or
1NP0485 (2 Stage).
All L.P./propane gas equipment must conform to the
safety standards of the National Fire Protection Associ-
ation.
For satisfactory operation, adequate L.P./propane gas
pressure must be provided at the unit manifold under
full load. Maintaining proper gas pressure depends on
three main factors:
1. The vaporization rate depends on (a) the tempera-
ture of the liquid and (b) the “wetted surface” area
of the container or containers.
2. The proper pressure regulation. (Two-stage regula-
tion is recommended from the standpoint of both
cost and efficiency.)
3. The pressure drop in the lines between regulators
and between the second stage regulator and the
appliance. Pipe size required will depend on the
length of the pipe run and the total load of all appli-
ances.
Complete information regarding tank sizing for vapor-
ization, recommended regulator settings, and pipe siz-
ing is available from most regulator manufacturers and
L.P./propane gas suppliers.
L.P./propane gas is an excellent solvent and special
pipe compound must be used when assembling piping
FIRE OR EXPLOSION HAZARD
Failure to follow the safety warning exactly
could result in serious injury, death or property
damage.
Never test for gas leaks with an open flame.
use a commercially available soap solution
made specifically for the detection of leaks to
check all connections. A fire or explosion may
result causing property damage, personal
injury or loss of life.

for this gas as it will quickly dissolve white lead or most
standard commercial compounds. Shellac base com-
pounds such as Rectorseal #5 are satisfactory for this
type of gas.
Check all connections for leaks when piping is com-
pleted, using a soap solution. NEVER USE A FLAME.
VENT AND COMBUSTION AIR HOODS
The vent hood and combustion air hood (with screens)
are shipped attached to the blower housing in the
blower compartment. These hoods must be installed to
assure proper unit function. All hoods must be fastened
to the outside of the gas heat access panel with the
screws provided in the bag also attached to the blower
housing.
The screen for the combustion air intake hood is
secured to the inside of the access panel opening with
three fasteners and the screws used for mounting the
hood to the panel. The top flange of this hood slips in
under the top of the access panel opening when install-
ing. Refer to Vent and Combustion Air Hood Figure 6.
The vent hood is installed by inserting the top flange of
the hood into the slotted opening in the access panel
and securing in place.
The products of combustion are discharged horizon-
tally through this screened, hooded vent opening on
the gas heat access panel.
ECONOMIZER/MOTORIZED DAMPER AND RAIN
HOOD
The instruction for the optional economizer/motorized
damper and rain hood can be found in form 035-
07364-000. Use these instructions when field assem-
bling an economizer rain hood onto a unit. The outdoor
and return air dampers, the damper actuator, the
damper linkage, the outdoor and return air divider baf-
fles, and all the control sensors are factory mounted as
part of the “Factory installed” economizer/motorized
damper options.
POWER EXHAUST/BAROMETRIC RELIEF DAMPER
AND RAIN HOOD
The instructions for the power exhaust/barometric relief
damper and rain hood can be found in form 530.18-
N1.10V.
All of the components, including the dampers, hard-
ware, and mounting instructions are shipped in a single
package external from the unit and must be field
assembled and installed.
FIRE OR EXPLOSION HAZARD
Failure to follow the safety warning exactly
could result in serious injury, death or property
damage.
Never test for gas leaks with an open flame.
use a commercially available soap solution
made specifically for the detection of leaks to
check all connections. A fire or explosion may
result causing property damage, personal
injury or loss of life.
FIGURE 6 - VENT AND COMBUSTION AIR HOOD
An adhesive backed label is provided over the
outside of the combustion air inlet opening to
prevent moisture from entering the unit, which
could cause damage to electrical components.
Allow this closure label to remain in place until
the combustion air hood is to be installed.

Power exhaust is only available as a field installed
accessory.
ECONOMIZER AND POWER EXHAUST DAMPER
SET POINT ADJUSTMENTS AND INFORMATION
Remove the economizer access panel from the unit.
Loosen but do not remove the two panel latches.
Locate the economizer control module, where the fol-
lowing adjustments will be made.
Check that the damper blades move smoothly without
binding; carefully turn the Minimum Position Adjusting
screw (found on the damper control module) fully
clockwise and then set the thermostat indoor fan switch
to the on position and then off, or energize and de-
energize terminals “R” to “G”.
MINIMUM POSITION ADJUSTMENT
With thermostat set to indoor fan on position, or termi-
nals “R” to “G” energized, turn the Minimum Position
Adjusting screw (located on the damper control mod-
ule) counterclockwise until the desired minimum
damper position has been attained.
ENTHALPY SET POINT ADJUSTMENT
The enthalpy set point may now be set by selecting the
desired setpoint shown in the Enthalpy Setpoint Adjust-
ment Figure 7. Adjust as follows:
• For a single enthalpy operation carefully turn
the set point adjusting screw (found on the
damper control module) to the “A”, “B”, “C” or
“D” setting corresponding to the lettered curve
of the Enthalpy Setpoint Adjustment Figure 7.
• For a dual enthalpy operation, carefully turn
the set point adjusting screw fully clockwise
past the “D” setting.
POWER EXHAUST DAMPER SETPOINT (WITH OR WITH-
OUT POWER EXHAUST)
• With no power exhaust option, adjust the
Exhaust Air Adjustment Screw fully clockwise.
• With power exhaust option, each building pres-
surization requirement will be different. The
point at which the power exhaust comes on is
determinedby the economizerdamper position
(Percent Open). The Exhaust Air Adjustment
Screw should be set at the Percent Open of
the economizer damper at which the power
exhaust is needed. It can be set from 0 to
100% damper open.
INDOOR AIR QUALITY
Indoor Air quality (indoor sensor input): Terminal AQ
accepts a +2 to +10 Vdc signal with respect to the
(AQ1) terminal. When the signal is below it's setpoint,
the actuator is allowed to modulate normally in accor-
dance with the enthalpy and mixed air sensor inputs.
When the AQ signal exceeds it's setpoint setting and
there is no call for free cooling, the actuator is propor-
tionately modulated from the 2 to 10 Vdc signal, with 2
Vdc corresponding to full closed and 10 Vdc corre-
sponding to full open. When there is no call for free
cooling, the damper position is limited by the IAQ Max
damper position setting. When the signal exceeds it's
setpoint (Demand Control Ventilation Setpoint) setting
and there is a call for free cooling, the actuator modu-
lates from the minimum position to the full open posi-
tion based on the highest call from either the mixed air
sensor input or the AQ voltage input.

Replace the economizer access panel.
Extreme care must be excercised in turning all
setpoint, maximium, and minimum damper
positioning adjustment screws to prevent twist-
ing them off.
