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. Damage
or repairs due to installation of unmatched systems is not
covered under the warranty.
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 R-410A 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, nonporous 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.
6 Installation Location
NOTE: These air handlers are designed for indoor installation
only.
The AVPTC**14** product line may be installed in one of the
upflow, downflow, horizontal left or horizontal right orientations
as shown in Figures 2, 3, 4 and 5. The unit may be installed in
upflow or horizontal left orientation as shipped (refer to specific
sections for more information).
3
Minor field modifications are necessary to convert to downflow
or horizontal right as indicated in below sections.
6.1 Upflow Installation
No field modifications are mandatory; however, to obtain
maximum efficiency, the horizontal drip shield, side drain pan
and drain pan extension can be removed.
Side Drain Pan and Extension Removal: Refer to Figure 1, remove the two (2) screws that secure the drip shield support
brackets to the condensate collectors (front and back). Unsnap the side drain pan from the main drain pan using a screw
driver or any small lever. The side drain pan, drip shield brackets and the drain pan extension may now be removed. From
Figure 1, drain port labeled (A) is the primary drain for this
application and condensate drain line must be attached to
this drain port. Drain port (a) is for the secondary drain line (if
used).

6.2 Horizontal Left Installation
No field modifications are permissible for this application.
The bottom right drain connection is the primary drain for
this application and condensate drain line must be attached
to this drain connection. The top connection of the three drain
connections on the drain pan must remain plugged for this
application. The bottom left drain connection is for the secondary drain line (if used).
In applications where the air handler is installed in the horizontal left position, and the return air environment see humidity levels above 65% relative humidity coupled with total
external static levels above 0.5” e.s.p., a condensate kit is
available for field application. Kit nomenclature can be found
in Table 1.
Refer to Figure 6 and 7 for the location of the components referenced in the following steps.
1. Before inverting the air handler, remove blower access
panel and coil access panel. The coil access panel and
tubing panel may remain screwed together during this
procedure. Remove and retain the seven (7) screws
securing the coil access panel to the cabinet and the six
(6) screws securing the blower access panel to the
cabinet.
2. Slide the coil assembly out using the drain pan to pull the
assembly from the cabinet.
NOTE: DO NOT USE MANIFOLDS OR FLOWRATOR TO
PULL THE COIL ASSEMBLY OUT. FAILURE TO DO SO MAY
RESULT IN BRAZE JOINT DAMAGE AND LEAKS.
3. Removal of the center support is required on units with
21" wide cabinet. Remove and retain the two (2) screws
that secure the center support to the cabinet. Remove
the center support.
4. Using the drain pan to hold the coil assembly, slide the
coil assembly back into the cabinet on the downflow
brackets as shown in Figure 8.
5. Re-install the center support (if removed) using the two

NOTE: Refrigerant tubing must be routed to allow adequate ac-
cess 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.
UPFLOW DOWFLOW
Figure 2 Figure 3
NOTE: If removing only the coil access panel from the unit, the
filter access panel must be removed first. Failure to do so may
result in panel damage.
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 casing. On these installations, a wrap of 2" fiberglass insulation
with a vapor barrier is recommended.
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.
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.
This product is factory-shipped with R410A and dry
nitrogen mixture gas under pressure. Use appropriate
service tools and follow these instructions to prevent
injury.
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 the size of the tube. Service personnel must
use the appropriate heat level for the size of the tube being
brazed.

7.4 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 temperatice 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 9°F and
superheat of 7 to 9°F
a. If subcooling and superheat are low, adjust TXV to 7 to
9°F, and 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 9°F, and then check superheat.
c. If subcooling and superheat are high, adjust TXV valve to
7 to 9° superheat, then check subcooling.
d. If subcooling is high and superheat is low, adjust TXV valve
to 7 to 9° superheat and remove charge to lower the subcooling
to 7 to 9°F.
NOTE: Do NOT adjust the charge based on suction pressure unless there is a gross undercharge.
4. Disconnect manifold set, and installation is complete
NOTE: Check the Schrader ports for leaks and tighten valve cores
if necessary. Install caps finger-tight.

8 Condensate Drain Lines
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 separately from the primary drain and end it where condensate discharge can be easily
seen.
NOTE: Water coming from secondary line means the coil primary
drain is plugged and needs immediate attention.
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.

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.
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 Lshaped 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 Achieving 1.4% and 2.0% Airflow 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 coil 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 @ 0.5 inch wc static
pressure and less than 2% airflow leakage @1inch wc static pressure when tested in accordance with ASHRAE Standard 193.
12 Electric Heat
Do not operate this product without all the ductwork
attached.

HEATE R (kW)
MINIMUM CFM REQUIREMENTS FOR HEATER KITS
Table 5
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 3, 4 and 5 to determine the temperature rise (°F).
NOTE: For installations not indicated above the following formula
is to be used:
TR = (kW x 3412) x (Voltage Correction) / (1.08 x CFM)
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
VC* (Voltage Correction)
