6 Pre-Installation Considerations

6.1 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.

6.2 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.

6.3 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.

6.4 Clearances

7.2 Horizontal Left Installation

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.

6.5 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 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 1, 2, 3 and 4. The unit may be installed in upflow or horizontal left orientation as shipped (refer to specific sections for more information).

Field modifications are necessary to convert to downflow or horizontal right as indicated in below sections.

7.1 Upflow Installation

No field modifications are mandatory however to obtain maximum rated efficiency, the horizontal drip shield must be removed. Without removal of the horizontal drip shield, performance will be reduced by up to a few percentage points.

Drip Shield Removal: Refer to Figure 9, 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).

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).

7.3 Downflow Installation

IMPORTANT NOTE: To prevent the coil pan from “sweating”, the DPI accessory insulation kit must be used when performing this conversion. The DPI kit is not supplied with this product and is to be purchased separately. See Table 1 for the correct DPI kit. Follow the instructions provided in the kit for appropriate installation.

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 size o f th e tub e . S er v ic e p e rsonnel must use the appropriate heat level for the size of the tube being brazed.

8.3 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 Goodman® 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.

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.

8.1 Tubing Size

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

8.2 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.

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.

8.4 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.

9 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.

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

Excessive torque can cause orifices to stick. Use the proper torque settings when tightening orifices.

8.5 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.

3. Replace the refrigerant tubing panel.

4. Remove the spin closure on both the liquid and suction tubes using a tubing cutter.

5. Insert liquid line set into liquid tube expansion and slide grommet about 18" away from braze joint.

6. Insert suction line set into suction tube expansion and slide insulation and grommet about 18" away from braze joint.

7. Braze joints. Quench all brazed joints with water or a wet rag upon completion of brazing.

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 i s not installed, 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. Goodman® 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.
