7 SECTION IlI: CLEARANCE AND RETURN AIR REQUIREMENTS Location Access for servicing is an important factor in the location of any air handler. Provide a minimum of 0 inches in front of the appliance for access to the control box, heating elements, blower and air filters. This access may be provided by a closet door or by locating the appliance so that a wall or partition is not less than 0 inches from the front access panel. Location is usually predetermined. Refer to Figure below. Check with owner s or dealer s installation plans. If location has not been decided, consider the following in choosing a suitable location.. Select a location with adequate structural support, space for service access, and clearance for return and supply duct connections.. Normal operating sound levels may be objectionable if the air handler is placed directly over or under some rooms such as bedrooms, study, etc.. Caution should be taken to locate the unit so that supply and return air ducts are about the same length causing even air distribution of supply and return air to and from the living spaces.. Locate appliance where electrical supply wiring can be easily routed to main electrical panel and where electrical wiring will not be damaged.. Locate appliance where control wiring can be easily routed to the controller and where the wiring will not be damaged. 6. Locate appliance where refrigerant lines can be easily routed from the evaporator coil to the system. 7. Locate the appliance where condensate lines can be easily routed to an available drain. Be sure to route condensate drain piping so as not to obstruct access to the air filter. 8. The coil is installed in a draw-thru application and will create a negative pressure situation in the condensate drain system. To prevent condensate from being drawn into the blower it is recommended to trap the primary (Main) and secondary (Overflow) drain line. Refer to CONDENSATE DRAIN SYSTEM and Figure 6 in these instructions. If the secondary drain is not used, it must be capped. This unit has a connection terminal for drain system monitoring. Refer to CONTROL WIRING AND CONNECTION section for information regarding connection of field-provided condensate overflow devices. 9. The draw-thru design will cause exterior surface of cabinet to sweat when unit is installed in a non-conditioned space such as an attic or garage. Installer must provide protection such as full size auxiliary drain pan on all units installed in a non-conditioned space to prevent damage from condensation runoff. Some states, cities and counties require additional insulation to be installed on the exterior casing of the air handler to prevent sweating. Refer to the state, city, county or local code for insulation requirement to be sure the installation is in compliance. It is recommended that air handlers installed in non-conditioned spaces be insulated on the exterior of the entire cabinet, including the front access panel with one () inch thick fiberglass with the vapor barrier on the outside. Figure : Clearance Access for service Appliance Clearances This appliance is approved for zero (0) inches clearance to combustible material on any part of the air handler exterior casing and the inlet or outlet ducts providing NO electric heater is being used (refer to figure ) There is a one () inch clearance on the supply plenum and supply air duct when an electric heater is installed in the appliance.
