HIGH VOLTAGE! To prevent the risk of property damage, personal injury, or death, do not store combustible materials or use gasoline or other flammable liquids or vapors in the vicinity of this unit. Disconnect ALL power before servicing. Multiple power sources may be present. Failure to do so may cause property damage, personal injury or death.

To register your Amana® brand unit, go to www.amanahac.com and click “Warranty Registration”. Complete registration as prompted. Product limited warranty certificates for models currently in production can be viewed at www.goodmanmfg.com or www.amana-hac.com. If your model is not currently in production or does not appear on the website, please contact your installing contractor or contact customer service (877254-4729) to obtain a copy of your warranty certificate.

7.2 Horizontal Left Installation 6.4 Clearances No field modifications are permissible for this application. 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.

. 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 7. 6. Re-install the center support (if removed) using the two (2) screws removed in Step 4. 7. Re-install the access panels removed in Step 1 as shown in Figure 8. 8. The bottom left drain connection is the primary drain for this application and condensate drain line must be attached to this drain connection.

CAUTION Screw 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. 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.

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. 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.

11 Return Air Filters Drain Connection Air Handler 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). 2" MIN.

• Refer to the NEC (USA) or CSA (Canada) for wire sizing. The unit MCA for the air handler and the optional electric heat kit can be found on the unit Series and Rating Plate. • Wire must be sized to allow no more than a 2% voltage drop from the building breaker/fuse panel to the unit. • Wires with different insulation temperature rating have varying ampacities - be sure to check the temperature rating used.
PAGE 12
13.6 Speed Tap Adjustment ARUF**14** and ARPT**14** air handlers have multispeed 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.

SPLIT SYSTEMS AIR CONDITIONING AND HEAT PUMP HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS We strongly recommend a bi-annual maintenance checkup be performed before the heating and cooling seasons begin by a qualified servicer. Clean Outside Coil (Qualified Servicer Only) Replace or Clean Filter 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.
