wiring and for servicing the unit (see Fig. 4). Do not exceed
maximum total pipe lengths.
Mount indoor compressor section on a rigid, sohd platform
or concrete floor. Insert the asphalt impregnated felt pad
(factory supplied in container) between the unit basepan and
moimting surface to provide fuU unit support and for vibra­
tion attenuation. Do not use vibration isolators under cor­

Install unit to permit adequate clearance for service on all
sides of the unit. A heat sink which is used to provide elec­

Do not enclose this area, in any manner. Failure to provide
proper ventilation can cause equipment to malfunction.
