4. 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 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 clear ances 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
