FEATURES
Condensate Removal (Standard)
RetroAire replacement unit, cooling operation, is designed
to eliminate condensate by slinging it onto outdoor coil.
• Condensate drains through the bulkhead to the area
near the outdoor fan.
• Unit as part of normal operation produces condensate
and collects it in the unit's base pan. It is picked up
there by the outdoor fan slinger ring and deposited onto
the condenser coil. This improves the unit’s efciency
by maintaining reduced refrigeration system pressures.
• Base pan has overow notches. If too much condensate
is produced notches allow condensate to ow out of the
base pan and into the wall sleeve out of the building.
Random Start Feature (Standard)
Random start feature is initiated on initial power-up or
after a power interruption.
• Controller adds a random time delay (from 5–120
seconds) on start-up, preventing compressor from
starting.
• This staggers the start of multiple units in a single
facility, preventing a large surge if all units started at
the same time.
Anti-Short Cycle Timer (Standard)
Microprocessor control uses this timing to prevent
compressor short-cycling.
• When the compressor cycles off on heating or cooling
call, controller starts a 180-second timer.
• Compressor is not allowed to start until this time has
elapsed.
• On initial power-up or after a power failure, this timing
occurs after the random start timing.
Power Cord With Integral Safety Protection
(Standard)
All PTAC/PTHP units rated 250V or less are equipped with
power cord with integral safety protection as standard.
• Providing personal shock protection as well as arcing
and re prevention. Device is designed to sense any
damage in line cord and disconnect power before a re
can occur.
• Tested in accordance with Underwriters Laboratories,
cord set offers a unique “passive” operation, meaning
unit does not require resetting if main power is
interrupted.
Hydronic Heating (Optional)
Hydronic heat package may be selected in lieu of electric
heat. Heating operation is same as that of units with
electric heat.
Aquastat Connection (Optional)
All replacement PTAC/PTHP's with hydronic heat are
supplied with standard line volt Aquastat connection. Field
installed Aquastat delays fan operation until hydronic coil
reaches temperature of 100°F (38°C).
Motorized Fresh Air Damper (Optional)
Motorized fresh air damper allows fresh air into the space
to be conditioned. When the Fresh Air switch is in "YES"
position, damper door is open and allows fresh air into
the space. This is only available when the indoor fan is
on. When damper door switch is in the "NO" position, the
damper door is closed and does not allow air in the space.
Optional Wall-Mounted Thermostats
PTAC compatible thermostats.
• Manufacture offers single stage, cool/heat, thermostat
that can be used in all RetroAire cooling, heating or
heat pump applications.
• Thermostat has adjustable setpoint range of between
45°F (7°C) and 90°F (32°C).
• For heat pumps manufacture offers a 2 stage heat/cool
thermostat which allows for emergency heat.
Selecting A Thermostat
When selecting a thermostat for the PTACchoose a single
stage heat/cool, 24V thermostat.
Straight cooling with electric heat or hydronic heat (R10C
— PTAC's) oling/electric heat system. Thermostat should
have “R”, “Y”, “ W”, "C" and “G” terminals.
Heat Pump With Electric Heat (R__H - PTHPS)
Select a thermostat compatible with cooling/single-stage
heat/heat pump system.
Thermostat should have "R", "Y", "O" and "G" terminals.

Aquastat [AS], the indoor fan start will be
delayed until the hydronic coil reaches 100
± 5 ºF (38 ± 3 ºC). The signal to the water
or steam valve will continue until the room
temperature rises above the set point by 3 ºF
(2 ºC). If the FCS is set to “Off”, the indoor
fan will continue to operate for 60 seconds or
until the hydronic coil temperature as sensed
by the Aquastat reaches 80 ± 5 ºF (26 ± 3
ºC), whichever occurs rst. If the FCS is set
to “On”, the indoor fan will de-energize if the
Aquastat senses a temperature of 80 ± 5 ºF
(26 ± 3 ºC) or below.

FINAL INSPECTION & START-UP
Before Operating The Unit
1.
Install unit per the instructions outlined in this manual
and all applicable local and national codes.
2.
Verify electrical supply matches electrical requirements
of the unit, and unit is properly grounded.
3.
Examine control box. Verify all wire connections are
secure, and control board jumpers are in proper
positions.
4.
Verify chassis is properly tted to wall sleeve and
securely mounted to surrounding framing.
5.
Verify chassis is level: Pour water into drain pan.
Verify it ows through the drain hoses to condenser
side of unit.
6.
Verify indoor blower wheels and outdoor fan blades are
secured to their motor shafts, and rotate freely.
7.
Verify all sheet metal panels are in place and secure.
8.
Attach front panel to the existing cabinet enclosure.
9.
Verify nothing interferes with room discharge air or
return air of units.
Examples:
Check for curtains or drapes that obstruct air ow. See
Figure 10 and Figure 11.
Check for plush carpeting that can obstruct return air.
These types of obstructions can cause serious damage
to the chassis.
Figure 10 - Proper Air Flow Diagram
Figure 11 - Restricted Air Flow Diagram
Any obstruction of supply air, including use of deector
bafes, may cause condensate to form on louver or
cabinet. See Figure 11.
For optimum performance of your PTAC/PTHP, avoid
restricting the air ow. Position of curtains or drapes
over supply air grille may cause air to recirculate without
cooling the room. Unit will short cycle and may cause
premature compressor failure. See Figure 11.

TROUBLESHOOTING
!
WARNING
Electrical shock hazard. Disconnect power to unit
before servicing or accessing control compartment.
Failure To follow these instructions could result in
death or serious injury.
Symptom Suggestion
No heat or cooling • Check to see if unit has power and if thermostat is satised. If
thermostat is not satised, call your installing contractor or service
contractor.
Thermostat calls for cooling, but
cool air is not coming out of unit.
Light on circuit board is
blinking.
Circuit board light is blinking 3
or 4 times, but there is no freeze
condition.
Thermostat is satised, but fan
is still running.
Thermostat calls for heat, but no
heat comes out of unit.
Thermostat calls for heat while in
heat pump mode, but heated air
is not coming out of unit.
• Check for continuity between thermostat and unit. Verify 24Vac is
present across terminals C and R.
• Verify high pressure switch located in outdoor section has not been
tripped. If tripped, press switch button to restart compressor.
• Note: If evaporator fan is operational and all of above suggested
procedures have been followed, and there is still no cooling being
supplied by unit, contact trained heating and cooling professional.
• Circuit board uses light for diagnostic purposes. Blinking codes are as
follows:
– 1 blink = normal operation
– 2 blinks = compressor lockout (ASCT — Anti-short cycle timer)
– 3 blinks = outdoor freeze condition
– 4 blinks = indoor freeze condition
– 5 blinks = simultaneous Y and W call (Straight cool units only)
• Verify sensors have not been damaged. Remove sensor wires from control
board and make resistance measurements, compare to following sensor
resistances. Indoor and outdoor coil sensor wires are labeled, as is control
board.
– 77°F = 10KOhms
– 50°F = 19.9KOhms
– 35°F = 30KOhms
– 30°F = 34.4KOhms
• If thermostat is set to auto mode, once thermostat is satised, fan will
stay energized for extra 60 seconds to purge unit of excess cool or warm
air in plenum.
• If thermostat fan switch is set to ON, fan will stay energized regardless
of whether thermostat is satised or not. Only way to turn fan off is to
turn unit off or turn thermostat fan switch to AUTO.
• Units equipped with electric heaters have temperature limit switch to
prevent electric heater from reaching unsafe temperatures. If after calling
for heating, heater is not energized, check for continuity across limit. If
limit is open, replace with equivalent limit switch.
• Verify unit has power or thermostat has been satised. If unit has power
and thermostat is satised, turn thermostat few degrees above room
temperature.
• While in heat pump mode, verify thermostat is not energizing O terminal.
Retroaire units are designed to work in heat pump mode when 24Vac
is present across Y and C. Verify heat pump jumper on control board
is jumping two pins labeled “HP”. See control board jumper locations,
Figure 9, Page 17.
• Verify there are no freeze conditions. Refer to blinking codes question
above for more information.
Have qualied technician conduct troubleshooting
procedures.
