2. CHOOSING LOCATION FOR THE UNIT

This air conditioner/heat pump is specifically designed for installation on the roof of a recreational vehicle (RV).

A.FOR ONE UNIT INSTALLATION:

The air conditioner/heat pump should be mounted slightly forward of center (front to back) and centered from side to side.

B.FOR TWO UNIT INSTALLATIONS:

Install one air conditioner/heat pump one-third and one air conditioner two-thirds from front of RV and centered from side to side. It is preferred that the air conditioner/ heat pump be installed in a relatively flat and level roof section measured with the RV parked on a level surface.

C.AFTER LOCATION HAS BEEN SELECTED:

1.Check for obstructions in the area where air condi- tioner/heat pump and return air cover will be in- stalled.

2.The roof must be designed to support 130 pounds when the RV is in motion. Normally a 200 lbs. static load design will meet this requirement.

CAUTION

It is the responsibility of the installer of this air conditioner/heat pump system to ensure structural integrity of the RV roof. Never cre- ate a low spot on the roof where water will collect. Water standing around the air con- ditioner/heat pump may leak into the inte- rior causing damage to the product and the RV.

3. AIR DISTRIBUTION SYSTEM SIZING &
