5 Pre-Installation Considerations

5.1 Preparation

Keep this document with the unit. Carefully read all
instructions for the installation prior to installing prod­uct. Make sure each step or procedure is understood
and any special considerations are taken into account
before starting installation. Assemble all tools, hard­ware and supplies needed to complete the installation.
Some items may need to be purchased locally. Make
sure everything needed to install the product is on hand
before starting.

5.2 System Matches

The entire system (combination of indoor and outdoor
sections) must be manufacturer approved and Air-Con­ditioning, Heating, and Refrigeration Institute (AHRI)
listed. NOTE: Installation of unmatched systems is not
permitted.

5.3 Interconnecting Tubing

Give special consideration to minimize the length of
refrigerant tubing when installing air handlers. Refer
to Remote Cooling/Heat Pump Service Manual
RS6200006, and TP-107 Long Line Set Application R­410A for tubing guidelines. If possible, allow adequate
length of tubing such that the coil may be removed (for
inspection or cleaning services) from the cabinet with­out disconnecting the tubing.

5.4 Clearances

The unit clearance from a combustible surface may be
0". However, service clearance must take precedence.
A minimum of 24" in front of the unit for service clear­ance is required. Additional clearance on one side or
top will be required for electrical wiring connections.
Consult all appropriate regulatory codes prior to de­termining final clearances. When installing this unit in
an area that may become wet (such as crawl spaces),
elevate the unit with a sturdy, non-porous material. In
installations that may lead to physical damage (i.e. a
garage) it is advised to install a protective barrier to
prevent such damage. Always install units such that a
positive slope in condensate line (1/4" per foot) is al­lowed.

5.5 Horizontal Applications

If installed above a finished living space, a secondary
drain pan (as required by many building codes), must
be installed under the entire unit and its condensate
drain line must be routed to a location such that the
user will see the condensate discharge.

7 Refrigerant Lines

This product i s factory-shipped with R410A and dry
nitrogen mixture gas under pressu re. Use appr opria te
service tools and follow these instructions to prevent
injury .

NOTE: Refrigerant tubing must be routed to allow adequate
access for servicing and maintenance of the unit.

7.1 Tubing Size

For the correct tubing size, follow the specification for
the condenser/heat pump.

7.2 Tubing Preparation

All cut ends are to be round, burr free, and clean. Fail­ure to follow this practice increases the chances for
refrigerant leaks. The suction line is spun closed and
requires tubing cutters to remove the closed end.

NOTE: To prevent possible damage to the tubing joints,
do not handle coil assembly with manifold or flowrator
tubes. Always use clean gloves when handling coil as­semblies.

7.3 Special Instructions

Units without a factory installed TXV come equipped
with a flowrator piston for refrigerant expansion. For
most installations with matching applications, no
change to the flowrator piston is required. However,
in mix-matched applications, a flowrator piston
change may be required. See the piston kit chart (pro­vided in the literature packet) or consult your local
distributor for details regarding mix-matched
flowrator piston sizing. If the mix-match application
requires a different flowrator piston size, change the
flowrator piston in the flowrator body on the indoor
coil before installing the coil and use the procedure
in section 7.4.

NOTE: The use of a heat shield is strongly recommended
when brazing to avoid burning the serial plate or the
finish of the unit. Heat trap or wet rags must be used
to protect heat sensitive components such as service
valves and TXV valves sensing bulb.

Do not install the air handler in a location that violates the
instructions provided with the condenser. If the unit is
located in an unconditioned area with high ambient
temperature and/or high humidity, the air handler may be
subject to nuisance sweating of the air handler cabinet.
On these installations, a wrap of 2" fiberglass insulation
with a vapor barrier is recommended.

A quenching cloth is strongly recommended to prevent
scorching or marring of the equipment finish when
brazing close to the painted surfaces. Use brazing
alloy of 5% minimum silver content.

CAUTION

Applying too much heat to any tube can melt the tube. Torch
heat required to braze tubes of various sizes must be
proportional to th e s ize of th e tube. S er vice p er sonn el mu st
use the appropriate heat level for the size of the tube being
brazed.

7.7 Thermal Expansion Valve System Adjustment

Run the system at Cooling for 10 minutes until refrigerant
pressures stabilize. Use the following guidelines and meth­ods to check unit operation and ensure that the refrigerant
charge is within limits. Charge the unit on low stage.

1. Purge gauge lines. Connect service gauge manifold to
base-valve service ports.

2. Temporarily install a thermometer on the liquid line
at the liquid line service valve and 4-6" from the com­pressor on the suction line. Ensure the thermometer
makes adequate contact and is insulated for best pos­sible readings. Use liquid line temperature to deter­mine subcooling and vapor temperature to determine
superheat.

3. Check subcooling and superheat. Systems with TXV ap­plication should have a subcooling of 7 to 9ºF and su­perheat of 7 to 9 ºF.

a. If subcooling and superheat are low, adjust TXV to
7 to 9 ºF superheat, then check subcooling.

NOTE: To adjust superheat, turn the valve stem clockwise
to increase and counter clockwise to decrease.

b. If subcooling is low and superheat is high, add charge
to raise subcooling to 7 to 9ºF then check superheat.

c. If subcooling and superheat are high, adjust TXV
valve to 7 to 9 ºF superheat, then check subcooling.

d. If subcooling is high and superheat is low, adjust
TXV valve to 7 to 9 ºF superheat and remove charge to
lower the subcooling to 7 to 9ºF.

NOTE: Do NOT adjust the charge based on suction pressure
unless there is a gross undercharge.

4. Disconnect manifold set, installation is complete.

NOTE: Check the Schrader ports for leaks and tighten valve
cores if necessary. Install caps finger-tight.

SUBCOOL FORMULA =
SAT. LIQUID LINE TEMP. - LIQUID LINE TEMP.
SUPERHEAT FORMULA =
SUCT. LINE TEMP. - SAT. SUCT. TEMP.

NOTE: Expansion valve system in ASPT models are already

tuned for 16 SEER single stage Heat Pump, adjustment of
Expansion valve system is required in case subcool, superheat
does not match to Section 7.6.3 above or when these models
are installed with any other outdoor models.

NOTE: Water coming from secondary line means the coil
primary drain is plugged and needs immediate attention.

CAUTION

If secondary drain is not installed, the secondary
access must be plugged.

Insulate drain lines located inside the building or above a
finished living space to prevent sweating. Install a conden­sate trap to ensure proper drainage.

NOTE: When units are installed above ceilings, or in other
locations where damage from condensate overflow may
occur, it is MANDATORY to install a field fabricated auxiliary
drain pan under the coil cabinet enclosure.

The installation must include a “P” style trap that is lo­cated as close as is practical to the evaporator coil. See
Figure 12 for details of a typical condensate line “P” trap.

NOTE: Units operating in high static pressure applications
may require a deeper field constructed “P” style trap than
is shown in Figure 12 to allow proper drainage and prevent
condensate overflow.

The coil drain pan has a primary and a secondary drain with
3/4" NPT female connections. The connectors required are
3/4" NPT male, either PVC or metal pipe, and should be
hand tightened to a torque of no more than 37 in-lbs. to
prevent damage to the drain pan connection. An insertion
depth of approximately 3/8” to 1/2” (3-5 turns) should be
expected at this torque.

1. Ensure drain pan hole is not obstructed.

2. To prevent potential sweating and dripping on to fin­ished space, it may be necessary to insulate the con­densate drain line located inside the building. Use
Armaflex® or similar material.

A secondary condensate drain connection has been provided
for areas where the building codes require it. Pitch all drain
lines a minimum of 1/4" per foot to provide free drainage.
Provide required support to the drain line to prevent bow­ing. If the secondary drain line is required, run the line

Figure 12

NOTE: Trapped lines are required by many local codes. In

the absence of any prevailing local codes, please refer to
the requirements listed in the Uniform Mechanical Building
Code.

A drain trap in a draw-through application prevents air from
being drawn back through the drain line during fan opera­tion thus preventing condensate from draining, and if con­nected to a sewer line to prevent sewer gases from being
drawn into the airstream during blower operation.

Use of a condensate removal pump is permitted when nec­essary. This condensate pump should have provisions for
shutting off the control voltage should a blocked drain oc­cur. A trap must be installed between the unit and the con­densate pump.

IMPORTANT NOTE: The evaporator coil is fabricated with
oils that may dissolve styrofoam and certain types of plastics.
Therefore, a removal pump or float switch must not contain
any of these materials.

Tip: Priming the “P” trap may avoid improper draining at
the initial installation and at the beginning of the cooling
season.

9 Ductwork

This air handler is designed for a complete supply and re­turn ductwork system.

Do not operate this product without all the ductwork
attached.

NOTE: For installations not indicated above the following
formula is to be used:

TR = (kW x 3412) x (Voltage Correction) / (1.08XCFM)

Where: TR = Temperature Rise

kW = Heater Kit Actual kW
3412 = Btu per kW
VC* = .96 (230 Supply Volts)

= .92 (220 Supply Volts)
= .87 (208 Supply Volts)

1.08 = Constant
CFM = Measured Airflow

To ensure correct system performance, the ductwork is to
be sized to accommodate 350-450 CFM per ton of cooling
with the static pressure not to exceed 0.5" in w.c. Refer to
ACCA Manual D, Manual S and Manual RS for information on
duct sizing and application. Flame retardant ductwork is
to be used and sealed to the unit in a manner that will

prevent leakage.
NOTE: A downflow application with electric heat must have

an L-shaped sheet metal supply duct without any outlets or
registers located directly below the heater.

9.1 Return Ductwork

DO NOT LOCATE THE RETURN DUCTWORK IN AN AREA
THAT CAN INTRODUCE TOXIC, OR OBJECTIONABLE
FUMES/ODORS INTO THE DUCTWORK. The return
ductwork is to be connected to the air handler bot­tom (upflow configuration).

10 Return Air Filters

Each installation must include a return air filter. This fil­tering may be performed at the air handler using the fac­tory filter rails or externally such as a return air filter grille.
When using the factory filter rails, a nominal 16x20x1”,
20x20x1” or 24x20x1” (actual dimension must be less than
23-½”x20”) filter can be installed on a B, C and D cabinet
respectively (the cabinet size is the seventh letter of the
model number).

11 Electric Heat

Refer to the installation manual provided with the electric
heat kit for the correct installation procedure. All electric
heat must be field installed. If installing this option, the
ONLY heat kits that are permitted to be used are the HKS
series. Refer to the air handler unit’s Serial and Rating plate
or the HKS specification sheets to determine the heat kits
compatible with a given air handler. No other accessory
heat kit besides the HKS series may be installed in these air
handlers.

The heating mode temperature rise is dependent upon the
system airflow, the supply voltage, and the heat kit size
(kW) selected. Use data provided in Tables 4, 5, AND 6 to
determine the temperature rise (°F).

*VC (Voltage Correction)

NOTE: The Temperature Rise Tables can also be used to
estimate the air handler airflow delivery. When using these
tables for this purpose set the room thermostat to maximum
heat and allow the system to reach steady state conditions.
Insert two thermometers, one in the return air and one in
the supply air. The temperature rise is the supply air
temperature minus the room air temperature. Using the
temperature rise calculated, CFM can be estimated from
the TR formula above. See Service Manual for more
information.

FIRE HAZARD!
To avoid the risk of property damage, personal injury
or fire, use only copper conductors.

IMPORTANT NOTE: USE COPPER CONDUCTORS ONLY.

Knockouts are provided on the air handler top panel and
sides of the cabinet to allow for the entry of the supply
voltage conductors, as shown in Figure 13. If the knockouts
on the cabinet sides are used for electrical conduit, an
adapter ring must be used in order to meet UL1995 safety
requirements. An NEC or CEC approved strain relief is to be
used at this entry point. Some codes/municipalities require
the supply wire to be enclosed in conduit. Consult your
local codes.

12.5 Low Voltage Connections

Several combinations of low voltage schemes are pos­sible, depending on the presence of a heat kit and
whether the heat kit is single-stage or multi-stage,
whether the outdoor section is an air conditioner or
heat pump, and whether the outdoor section is single­stage or two-stage. The 24V-control voltage connects
the air handler to the room thermostat and condenser.
Low voltage wiring must be copper conductors. A mini­mum of 18AWG must be used for installations up to
100 feet. Low voltage wiring must be connected
through the top of the cabinet or either side. See the
“Thermostat Wiring” section of this manual for typi­cal low voltage wiring connections.

12.5.1 Thermostats

Second-stage heat can be accomplished by a multi­stage heating thermostat or the addition of an out­door thermostat as shown in wiring schematics on page

19. Follow the thermostat manufacturer’s instruc­tions for installation.

12.6 Speed Tap Adjustment

ARUF**14** air handlers have multi-speed PSC motors.
The color of the wire coming from the motor to the
“COM” terminal on the control board defines at which
speed the motor will operate. Black wire is high speed,
blue wire is medium speed and red wire is low speed.
To change speeds, remove the wire attached to the
“COM” terminal on the control board, and swap it
with the wire (on terminal “M1” or “M2”) with the
color that will give the desired speed.

KNOCK-OUT FOR ELECTRICAL CONNECTIONS

12.4.1 Air Handler Only (Non-Heat Kit Models)

The building supply connects to the stripped black
and red wires contained in the air handler electrical
compartment cavity. A ground screw is also contained
in this area. Attach the Supply wires to the air han­dler conductors as shown in the unit wiring diagram
using appropriately sized solderless connectors or
other NEC or CEC approved means.

12.4.2 Air Handler - Non-Circuit Breaker Heat
Kits

A terminal block is provided with the HKS kit to at­tach the power supply and air handler connections.
Follow the HKS Installation Manual and wiring diagram
for complete wiring details.

12.4.3 Air Handler With Circuit Breaker Heat Kit

The air handler has a plastic cover on the upper ac­cess panel that will require either one or both sec­tions to be removed to allow the heat kit circuit
breaker(s) to be installed. The circuit breakers have
lugs for power supply connection. See the HKS Instal­lation Instructions for further details.

ASPT**14** air handlers feature energy efficient blower
motors. The motors run at a constant torque with very
low power consumption and are energized by 24 VAC.
Adjust the CFM by changing the 24 VAC leads to the
desired speed tap on the terminal block. The ASPT
blower motor speeds are programmed to deliver ad­equate airflow at rated external static pressure and
with 60 second off time delay. For details, refer to
the specification sheet applicable to your model.

NOTE: In some models, not all speed taps are allowable for
certain electric heat applications. Refer to Table 5 for
minimum speed.

13 Achieving 1.4% Low Leakage Rate

Ensure all the gaskets remain intact on all surfaces as shipped
with the unit. These surfaces are areas between the upper
tie plate and blower access panel, blower access and coil
access panels, and between the coil access and filter access
panels. Ensure upon installation, that the plastic breaker
cover is sitting flush on the blower access panel and all ac­cess panels are flush with each other and the cabinet. With
these requirements satisfied, the unit achieves less than 1.4%
airflow leakage when tested in accordance with ASHRAE Stan­dard 193.

14 Start-Up Procedure

15 Regular Maintenance

The only item required to be maintained on a regular basis
by the user is the circulating air filter(s). Filter should be
cleaned or replaced regularly, typically once per month. A
certified service technician must perform all other services.

IMPORTANT NOTE: If thumb screws are used to access the
filter, ensure the washer installed on the screw behind the
access panel remains in place after re-installation.

HIGH VOLTAGE!
Disconnect ALL power before servicing or
installing this unit. Multiple power sources may
be present. Failure to do so may cause property
damage, personal injury or death.

• Prior to start-up, ensure that all electrical wires are
properly sized and all connections are properly tight­ened.

• All panels must be in place and secured. For Air Tight
application, gasket must be positioned at prescribed
locations to achieve 1.4% leakage.

• Tubing must be leak free.

• Condensate line must be trapped and pitched to al­low for drainage.

• Low voltage wiring is properly connected.

• Auxiliary drain is installed when necessary and pitched
to allow for drainage.

• Unit is protected from vehicular or other physical dam­age.

• Return air is not obtained from, nor are there any re­turn air duct joints that are unsealed in, areas where
there may be objectionable odors, flammable vapors
or products of combustion such as carbon monoxide
(CO), which may cause serious personal injury or death.

17 Air Handler Low Voltage Connections

The following composite wiring diagrams detail various configurations in which the air handlers can be used. Examples
include single-stage cooling and heat pump with single or two-stage electric heating. All these configurations can be
applied with convenient connections to outdoor thermostat applications.

The following sections are detailed:

• Single-Stage Cooling

• Heat Pump

Each diagram details the connections between room thermostat and the air handlers, and the connections between the
air handlers and the Condensing Unit (or Heat Pump) with optional connections to Outdoor Thermostats. For each
configuration, refer to the explanation of the proper jumper(s) to remove for the corresponding blower speed that will
result in the programmed fixed speed ECM motor.

IMPORTANT: WHEN MATCHING THE ASPT AIR HANDLERS TO A SINGLE SPEED COOLING OR HEAT
PUMP UNIT, REMEMBER TO CONNECT “Y” FROM THE THERMOSTAT TO THE “Y2” ON THE LOW
VOLTAGE TERMINAL BOARD.

Any equivalent thermostat can be used in place of the manufacturer’s thermostat part number.

AIR HANDLER

AIR HANDLER HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS

REPLACE OR CLEAN FIL TER

IMPORTANT NOTE: Never operate unit without a filter installed as dust and lint will build up on internal parts resulting in
loss of efficiency, equipment damage and possible fire.

An indoor air filter must be used with your comfort system. A properly maintained filter will keep the indoor coil of your
comfort system clean. A dirty coil could cause poor operation and/or severe equipment damage.

Your air filter or filters could be located in your furnace, in a blower unit, or in “filter grilles” in your ceiling or walls. The
installer of your air conditioner or heat pump can tell you where your filter(s) are, and how to clean or replace them.

Check your filter(s) at least once a month. When they are dirty, replace or clean as required. Disposable type filters
should be replaced. Reusable type filters may be cleaned.

You may want to ask your dealer about high efficiency filters. High efficiency filters are available in both electronic and
non-electronic types. These filters can do a better job of catching small airborne particles.

MOTORS

Indoor and outdoor fan motors are permanently lubricated
and do not require additional oiling.

ALUMINUM INDOOR COIL CLEANING
(QUALIFIED SERVICER ONLY)

This unit is equipped with an aluminum tube evaporator
coil. The safest way to clean the evaporator coil is to sim­ply flush the coil with water. This cleaning practice remains as the recommended cleaning method for both copper tube
and aluminum tube residential evaporator coils.

It has been determined that many coil cleaners and drain pan tablets contain corrosive chemicals that can be harmful to
aluminum tube and fin evaporator coils. Even a one-time application of these corrosive chemicals can cause premature
aluminum evaporator coil failure. Any cleaners that contain corrosive chemicals including, but not limited to, chlorine
and hydroxides, should not be used.

An alternate cleaning method is to use one of the products listed in TP-109* to clean the coils. The cleaners listed are the
only agents deemed safe and approved for use to clean round tube aluminum coils. TP-109 is also available on the web
site in Partner Link > Service Toolkit.

NOTE: Ensure coils are rinsed well after use of any chemical cleaners.

BEFORE YOU CALL YOUR SERVICER

• Check the thermostat to confirm that it is properly
set.

• Wait 15 minutes. Some devices in the outdoor unit or
in programmable thermostats will prevent compres­sor operation for awhile, and then reset automati­cally. Also, some power companies will install de­vices which shut off air conditioners for several min­utes on hot days. If you wait several minutes, the
unit may begin operation on its own.

• Check the electrical panel for tripped circuit breakers or failed fuses. Reset the circuit breakers or replace fuses
as necessary.

• Check the disconnect switch near the indoor furnace or blower to confirm that it is closed.

• Check for obstructions on the outdoor unit . Confirm that it has not been covered on the sides or the top. Remove
any obstruction that can be safely removed. If the unit is covered with dirt or debris, call a qualified servicer to
clean it.

• Check for blockage of the indoor air inlets and outlets. Confirm that they are open and have not been blocked by
objects (rugs, curtains or furniture).

• Check the filter. If it is dirty, clean or replace it.

• Listen for any unusual noise(s), other than normal operating noise, that might be coming from the outdoor unit. If
you hear unusual noise(s) coming from the unit, call a qualified servicer.
