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.
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 and will void the product 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, 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.
6 Installation Location
NOTE: These air handlers are designed for indoor installa-
tion only.
The ARUF**14**, ARPT**14**, ASPT**14** and ASUF**14**
product lines 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).
Minor field modifications are necessary to convert to downflow
or horizontal right as indicated in below sections.

7 Refrigerant Lines
This product is 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 .
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.
NOTE: Refrigerant tubing must be routed to allow adequate
access for servicing and maintenance of the unit.
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.
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.
ACCESS PANEL CONFIGURATION FOR DOWNFLOW
OR HORIZONTAL RIGHT
Figure 9
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.
CAUTION
Applying too much heat to any tube can melt the tube. T orch
heat required to braze tubes of various sizes mu st be
proportional to the s ize of t h e tub e . S er v ice p e rso n n el m u st
use the appropriate heat level for the size of the tube being
brazed.
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 8.4.
6
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.
7.4 Tubing Connections for Flowrator Model
1. Loosen the 13/16 nut 1 TURN ONLY to allow high pressure tracer gas to escape. No gas indicates a possible
leak.
2. After the gas has been expelled, remove the nut and
discard the black or brass cap plastic seal.
3. Remove the flowrator piston to verify it is the correct
size for the outdoor unit being installed and then replace
the piston (changing size, if needed). See piston kit chart
in the literature kit for appropriate piston size.
4. Remove the spin closure on the suction line using a
tube cutter and deburr the tube.
5. Insert the suction line into the connection, slide the insulation and the rubber grommet at least 18" away from
the braze joint.
7. Braze tailpiece to the line set liquid tube and braze suction line connection. Quench all brazed joints with a
damp rag upon completion of brazing. Do not allow water
to enter the inside of the tubing.
8. AFTER THE TAILPIECE HAS COOLED, confirm position of the white Teflon® seal and hand tighten the 13/16
nut.
9. Torque the 13/16 nut to 7-25 ft-lbs. or tighten 1/6 turn.
Excessive torque can cause orifices to stick. Use the
proper torque settings when tightening orifices.
7.5 Tubing Connections for TXV Models
TXV models come with factory installed TXV with the
bulb pre-installed on the vapor tube.
1. Remove refrigerant tubing panel or coil (lower) access
panel.
2. Remove access valve fitting cap and depress the valve
stem in access fitting to release pressure. No pressure
indicates possible leak.

7. Braze joints. Quench all brazed joints with water or a
wet rag upon completion of brazing.
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.
7
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.
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.
CAUTION
If secondary drain is not inst a lled, the seconda ry
access must be plugged.
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: 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.
Field experience has shown condensate drain traps with an
open vertical Tee between the air handler and the condensate drain trap can improve condensate drainage in some
applications, but may cause excessive air discharge out of
the open Tee. The manufacturer does not prohibit this type
of drain but we also do not recommend it due to the resulting
air leakage. Regardless of the condensate drain design used,
it is the installer’s responsibility to ensure the condensate
drain system is of sufficient design to ensure proper condensate removal from the coil drain pan.

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 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).
Do not operate this product without all the ductwork
attached.
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.
