* For wire length over 24 ft., consult the National Electrical Code for proper sizing.
** Dometic Corporation gives GENERAL guidelines for generator requirements. These guidelines come from experiences
people have had in actual applications. When sizing the generator, the total power usage of your RV must be considered.
Keep in mind generators lose power at high altitudes and from lack of maintenance.
*** CIRCUIT PROTECTION: Time Delay Fuse or Circuit Breaker Required.
B. Roof Requirements
● A 14-1/4″ x 14-1/4″ (±1/8″) square opening (hereinafter referred to as “roof opening”) is required for installing this
unit. This opening is part of the return air system of the unit and MUST be nished in accordance with NFPA 1192.
● Roof construction with rafters/joists support frames on a minimum of 16 inch centers.
● Minimum of 1.5 inches and maximum of 6 inches distance between roof to ceiling of RV.
A. Choosing Proper Location For Unit
This unit is specically designed for installation on the roof
of an RV. When determining your cooling requirements, the
following should be considered:
● Size of RV;
● Window area (increases heat gain);
● Amount of insulation in walls and roof;
● Geographical location where the RV will be
used;
● Personal comfort level required.
1. Normal locations-The unit is designed to t over
an existing roof vent opening.
2. Other locations-When no roof vent is available
or another location is desired, the following is
recommended:
a. For one unit installation: The unit should be
mounted slightly forward of center (front to
back) and centered from side to side.
b. For two unit installations: Install one unit 1/3
and one unit 2/3’s from front of RV and cen-
tered from side to side.
It is preferred that the unit be installed on a relatively at
and level roof section measured with the RV parked on a
level surface. See table below for maximum acceptable tilt.
