Pre-Installation Instructions

Carefully read all instructions for the installation prior to in- stalling product. Make sure each step or procedure is under- stood 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.

Location

NOTE: Air handlers are designed for indoor installation only.

Give special consideration to minimizing the length of refrig- erant tubing when installing air handlers. Refer to Remote Cooling/Heat Pump Service Manual, TP-106 Long Line Set Application R-22 or TP-107 Long Line Set Application R-410A for guidelines. The unit clearance from a combustible sur- face may be 0". However, service clearance is to take prece- dence. In addition allow a minimum of 24" in front of the unit for service clearance.

Do not install the air handler in a location that violates the instructions provided with the condenser.

If the unit is located in an area with high ambient temperature and/or high humidity the air handler maybe subject to nui- sance sweating of the casing. On these installations a wrap of 2” fiberglass insulation with a vapor barrier is recom- mended.

Consult all appropriate regulatory codes prior to determining final clearances. When installing this unit in an area that may become wet, elevate the unit with a sturdy, non-porous ma- terial. In installations that may lead to physical damage (i.e. a garage) it is advised to install a protective barrier to prevent such damage.

Ductwork

This air handler is designed for a complete supply and return ductwork system.

Do not operate this product without all the ductwork attached.

To ensure correct system performance, the ductwork is to be sized to accommodate 375-425 CFM per ton of cooling with the static pressure not to exceed .5" WC. Inadequate duct work that restricts airflow can result in improper performance and compressor or heater failure. Ductwork is to be con- structed in a manner that limits restrictions and maintains suitable air velocity. Ductwork is to be sealed to the unit in a manner that will prevent leakage.

Return Ductwork

DO NOT TERMINATE THE RETURN DUCTWORK IN AN AREA THAT CAN INTRODUCE TOXIC, OR OBJECTION- ABLE FUMES/ODORS INTO THE DUCTWORK. The return ductwork is to be introduced into the air handler bottom (upflow configuration).

Return Air Filters

Each installation must include a return air filter. This filtering may be performed at the air handler or externally such as a

return air filter grille. Air handlers mounted in the downflow orientation, including “B” series, require external filtering. A washable filter is available as an accessory. To ensure opti- mum performance frequent filter cleaning is advised. Refer to Table 1 for the appropriate filter.

Electric Heat

Refer to this manual in combination with the instructions pro- vided with the heat kit for the correct installation procedure.

The air handlers listed in this manual do not have factory installed electric heat. Electric heat is available as an acces- sory. If installing this option, the ONLY heat kits that can be used are the HKR series.

NOTE: The Amana® brand EHK, ECB, EDB, and EDK kits are NOT approved for use with 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 Tables 2, 3, and 4 to determine the tempera- ture rise (ºF).
