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 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.
3
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 installation 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.
6.1 Upflow Installation
No field modifications are mandatory however to obtain maximum efficiency,
the horizontal drip shield must be removed.
Drip Shield Removal: Refer to Figure 1, remove the two (2) screws that
secure the drip shield support brackets to the condensate collectors (one
screw per side). Remove the two (2) screws that secure the drip shield to the
drain pan. The drip shield and drip shield brackets may now be removed.
The bottom left 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 right drain connection 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 appli-
cation 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 horizontal condensate management kit is
available for field application. Kit nomenclature can be found in the
table above and in the specification sheets.

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
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.
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.
CAUTION
Applying too much heat to any tube can melt the tube. Torch
heat required to braze tubes of various sizes must be
proportiona l to the s ize of th e tub e. S erv ice p ersonn el m u st
use the appropriate heat level for the size of the tube being
brazed.
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
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.
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.

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.
6. Remove the tailpiece clamped to the exterior of the cabinet or in
the literature kit packet and slide the 13/16 nut into place.
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.
