User manual DOMETIC GENESIS INSTALLATION

[. . . ] During extremely high outdoor temperatures, the heat gain of the vehicle may be reduced by: 1. Avoiding the use of heat producing appliances Operation on High Fan/Cooling mode will give optimum or maximum efficiency in high humidity or high outside temperature. Starting the air conditioner/heat pump early in the morning and giving it a "head start" on the expected high outdoor ambient will greatly improve its ability to maintain the desired indoor temperature. For a more permanent solution to a high heat gain, accessories like A&E outdoor patio and window awnings will reduce heat gain by removing the direct exposure to the sun. [. . . ] The Duct material must meet or exceed any agency or RVIA Standard that may be in existence at the time the RV is produced. All Discharge Air Ducts must be properly insulated to prevent condensation from forming on their surfaces or adjacent surfaces during operation of the air conditioner/ heat pump. Ducts and their joints must be insulated and sealed to prevent condensation from forming on adjacent surfaces during operation of the air conditioner/heat pump. 4. AIR DISTRIBUTION SYSTEM INSTALLATION Dometic Corporation recommends the basic configuration shown in FIG. We have found by testing, that this configuration works best in most applications of this air conditioner/heat pump system. It is the responsibility of the Installer of this system to review each RV floor plan and determine the following: A. These items must be determined in conjunction with the Air Distribution System Sizing and Design Requirements listed in Section 3 of this manual. Important: Alternate configurations and methods may be used which still allow the air conditioner/heat pump to operate properly. However, these alternate configurations and methods must be approved by Dometic Corporation in writing. The following instructions are based upon the use of Dometic Genesis Air Filtration System No. Before preparing the ceiling opening, the type of system options must be decided upon. Read all of the instructions packaged with the system options before beginning the installation. CAUTION It is the responsibility of the installer to insure the ductwork will not collapse or bend during and after the installation. Dometic Corporation will not be liable for roof structural or ceiling damage due to improperly insulated, sealed or collapsed ductwork. H. Return Air to the air conditioner/heat pump must be filtered to prevent dirt accumulation on air conditioner/ heat pump cooling surface. Total System Static Air Pressure This is to be determined with the air conditioner/heat pump blower operating on High Speed and return air filter and grill in place. A 14-1/4" x 14-1/4" (±1/8") opening must be cut through the roof and ceiling of the RV. This opening must be located between the roof and reinforcing members. !WARNING There may be electrical wiring between the roof and the ceiling. Disconnect 115 volt AC power cord and the positive (+) 12 volt DC terminal at the supply battery. Failure to follow this instruction may create a shock hazard causing death or severe personal injury. 2. Mark a 14-1/4" x 14-1/4" (±1/8") square on the roof and carefully cut the opening. Using the roof opening as a guide, cut the matching hole in the ceiling. The opening created must be framed and sealed to provide adequate support and prevent air from being drawn from the roof cavity. [. . . ] If solar panel is installed see instructions pack aged with solar panel option. Slide the filter from the right side (looking toward the RV front) over the wires. See Figure 10.
