DUCT WORK
SERVICE ACCESS
These units are adaptable to downflow use as well as rear
supply and return air duct openings. To convert to downflow,
use the following steps:
Access to all serviceable components is provided by the
following removable panels:
• Blower service access
• Electrical/filter access
• Compressor service access
1.
Remove the duct covers found in the bottom return and
supply air duct openings. There are four (4) screws
securing each duct cover (save these screws to use later).
2.
Install the duct covers, removed in step one, to the rear
supply and return air duct openings. Secure with the four
(4) screws used in step one.
3.
Seal the duct covers with silicone caulking.
Downflow units must have an L-shaped supply duct without any
outlets or registers located directly below the supply outlet of
the unit.
Duct work should be designed and sized according to the
methods of the Air Conditioning Contractors of America
(ACCA), as set forth in their Manual D.
A closed return duct system shall be used. This shall not
preclude use of economizers or ventilation air intake. Flexible
joints may be used in the supply and return duct work to
minimize the transmission of noise.
When fastening duct work to the side duct flanges on
the unit, insert the screws through the duct flanges only.
DO NOT insert the screws through the casing. Outdoor
duct work must be insulated and waterproofed.
NOTE: Be sure to note supply and return openings.
Refer to Figure 7 for information concerning rear and bottom
supply and return air duct openings.
FILTERS
Single phase units are shipped without a filter and is the
responsibility of the installer to secure a filter in the return air
ductwork or install a Filter/Frame Kit (1FF0114).
A filter rack and a filters are standard on three phase units.
Filters must always be used and must be kept clean. When
filters become dirt laden, insufficient air will be delivered by the
blower, decreasing your units efficiency and increasing
operating costs and wear-and-tear on the unit and controls.
Filters should be checked monthly especially since this unit may
be used for both heating and cooling.
Refer to Figure 7 for location of these access panels and
minimum clearance.
THERMOSTAT
The room thermostat should be located on an inside wall
approximately 56" above the floor where it will not be subject to
drafts, sun exposure or heat from electrical fixtures or
appliances. Follow manufacturer's instructions enclosed with
the thermostat for general installation procedure. Four, five or
six color coded insulated wires (minimum #18 AWG) should be
used to connect thermostat to unit. See Figure 2.
POWER AND CONTROL WIRING
Field wiring to the unit must conform to provisions of the current
N.E.C. ANSI/NFPA No. 70 or C.E.C. and/or local ordinances.
The unit must be electrically grounded in accordance with local
codes or, in their absence, with the N.E.C./C.E.C. Voltage
tolerances which must be maintained at the compressor
terminals during starting and running conditions are indicated
on the unit Rating Plate and Table 1.
The wiring entering the cabinet must be provided with
mechanical strain relief.
A fused or HACR breaker disconnect switch should be field
provided for the unit. If any of the wire supplied with the unit
must be replaced, replacement wire must be of the type shown
on the wiring diagram.
Electrical line must be sized properly to carry the load. Each
unit must be wired with a separate branch circuit fed directly
from the meter panel and properly fused.
Refer to Figure 2 for typical field wiring and to the appropriate
unit wiring diagram for control circuit and power wiring
information.
COMPRESSORS
Units are shipped with compressor mountings factory-adjusted
for shipping.
Loosen compressor mounting bolts half turn before
operating unit.
CONDENSATE DRAIN
A condensate trap is required to be installed in the condensate
drain. The plumbing must conform to local codes. Use a sealing
compound on male pipe threads. Install the condensate drain
line (¾“ NPTF) to spill into an open drain.

CHECKING SUPPLY AIR CFM
4.
To check the supply air CFM after the initial balancing has been
completed:
1.
Remove the two ¼ inch dot plugs in the duct panel.
2.
Insert at least 8 inches of ¼ inch tubing into each of these
holes for sufficient penetration into the airflow on both
sides of the indoor coil.
3.
Knowing the pressure drop across a dry coil, the actual
CFM through the unit can be determined from the curve in
Coil Delta P vs. Supply Air CFM figure.
Failure to properly adjust the total system air quantity
can result in extensive system damage.
Using an inclined manometer, determine the pressure drop
across the dry evaporator coil. Since the moisture on an
evaporator coil may vary greatly, measuring the pressure
drop across a wet coil under field conditions would be
inaccurate. To ensure a dry coil, the compressors should
be deactivated while the test is being run.
After readings have been obtained, remove the tubes and
reinstall the two ¼ inch plugs removed in Step 1.
NOTE: De-energize the compressors before taking any test
measurements to ensure a dry indoor coil.

COOLING
COOLING
WITH POWER TO UNIT AND THERMOSTAT IN COOLING
MODE.
The following sequences of operation are based on using a
standard single-stage cooling thermostat.
1.
2.
3.
If the fan switch on the thermostat is in the “ON” position,
the 24 volts at “G” will energize the “K1" relay on the fan
control board, close the ”K1" relay contacts, and energize
the indoor blower motor. If the fan switch is in the “AUTO”
position, the blower will operate only when there is a call
for cooling by the thermostat.
On a call for cooling, the thermostat will send 24 volts to “Y”
on the fan control board. The 24 volt signal will energize
contactor “M1", and power will be supplied to the
compressor and outdoor fan motor. If the fan switch on the
thermostat is on the ”AUTO" position, the thermostat will
also send a 24 volt signal to “G” on the fan control board
and the indoor blower will operate as indicated in step 1.
When the demand for cooling has been satisfied, the “M1"
contactor will be de-energized when the 24 volt ”Y" signal
is removed. If the fan switch on the thermostat is energized
when the 24 volt “Y” signal is removed. If the fan switch on
the thermostat is in the “ON” position, the indoor blower will
continue to run. If the fan switch is in the “AUTO” position,
the 24 volt “G” signal will be removed, and after a 60
second delay, the “K1" relay will open and de-energize the
indoor blower motor.
HEATING
WITH POWER TO UNIT AND THERMOSTAT IN HEATING
MODE.
1.
If the fan switch on the thermostat is in the “ON” position,
the 24 volts at “G” will energize the “K1" relay contacts, and
energize the indoor blower motor. If the fan switch on the
thermostat is in the ”AUTO" position, the blower will
operate only when there is a call for heating by the
thermostat.
2.
On a call for heating, the thermostat will send 24 volts to
“W1" on the fan control board. The 24 volts signal will
energize relay ”K2" on the fan control board, and the first
stage of electric heat will be energized.
3.
When the heating demand is satisfied, the electric heat will
be de-energized when the 24 volt “W1" and ”W2" signals
are removed. If the fan switch on the thermostat is in the
“ON” position, the indoor blower will continue to run. If the
fan switch is in the “AUTO” position, the “K1" relay will
open and de-energize the indoor blower motor after the
appropriate time delay.
Please refer to Table 14 and 15 for more information.
WITH POWER TO UNIT AND THERMOSTAT IN COOLING
MODE.
1.
If the fan switch on the thermostat is in the “ON” position,
the 24 volts at “G” will be sent to the ECM indoor motor and
the blower will operate at the programmed airflow. If the fan
switch is in the “AUTO” position, the blower will operate at
the programmed airflow only when there is a call for
cooling by the thermostat.
2.
On a call for cooling, the thermostat will send 24 volts to “Y”
on the fan control board. The 24 volt signal will energize
contactor “M1", and power will be supplied to the
compressor and outdoor fan motor. If the fan switch on the
thermostat is on the ”AUTO" position, the thermostat will
also send a 24 volt signal to “G” on the fan control board
and the indoor blower will operate as indicated in step 1.
3.
When the demand for cooling has been satisfied, the “M1"
contactor will be de-energized when the 24 volt ”Y" signal
is removed. If the fan switch on the thermostat is in the
“ON” position, the indoor blower will continue to run. If the
fan switch is in the “AUTO” position, the 24 volt “G” signal
will be removed, and after a 30 second delay, the indoor
blower motor will shut down.
HEATING
WITH POWER TO UNIT AND THERMOSTAT IN HEATING
MODE.
1.
If the fan switch on the thermostat is in the “ON” position,
the 24 volts at “G” will be sent to the ECM indoor motor and
the blower will operate at the programmed airflow. If the fan
switch is in the “AUTO” position, the blower will operate at
the programmed airflow only when there is a call for
heating by the thermostat.
2.
On a call for heating, the thermostat will send 24 volts to
“W1" on the fan control board. The 24 volts signal will
energize relay ”K2" on the fan control board, and the first
stage of electric heat will be energized. The indoor blower
will operate as indicated in step 1.
3.
On units with 2 (two) stages of electric heat, the second
bank of heaters will be energized by a 24 volt signal to “W2"
on the fan control board. After a 20 second delay, the third
bank of heaters will be energized if the unit is so equipped.
4.
When the heating demand is satisfied, the electric heat will
be de-energized when the 24 volt “W1" and ”W2" signals
are removed. If the fan switch on the thermostat is in the
“ON” position, the indoor blower will continue to run. If the
fan switch is in the “AUTO” position, the indoor motor will
shut off after the appropriate time delay.

MAINTENANCE
NORMAL MAINTENANCE
Exercise care when cleaning the coil so that the coil fins
are not damaged.
Prior to any of the following maintenance procedures,
shut off all power to the unit, to avoid personal injury.
Do not permit the hot condenser air discharge to be
obstructed by overhanging structures or shrubs.
TROUBLESHOOTING
Periodic maintenance consists of changing or cleaning filters
and general cleaning of the outdoor coil.
FILTERS - Inspect once a month. Replace Disposable or clean
Permanent Type as necessary. DO NOT replace Permanent
Type with Disposable.
MOTORS - Indoor and outdoor fan motors are permanently
lubricated and require no maintenance.
OUTDOOR COIL - Dirt should not be allowed to accumulate on
the outdoor coil surface or other parts in the air circuit. Cleaning
should be as often as necessary to keep the coil clean. Use a
brush, vacuum cleaner attachment, or other suitable means. If
water is used to clean the coil, be sure that the power to the unit
is shut off prior to cleaning.
Troubleshooting of components necessarily requires
opening the electrical control box with the power
connected to the unit. Use extreme care when working
with live circuits! Check the unit nameplate for the
correct line voltage and set the volt meter to the correct
range before making any connections with line terminal
The wire number or color and terminal designations
referred to may vary. Check the wiring label inside the
control box access panel for the correct wiring.
If the variable speed motor found in the DPH048 and DPH060
models operates erratically, check the fan control board for the
presence of a c break-off tab. Remove tab if present.
