2. COMPONENT MATCH-UP 1. 6535 Series Package Heat Pump. (Reference specifications for model number breakdown and identification.) 3. 2. 6535-3451 or 6535-335* Electronic 12 VDC Wall Mounted Thermostat. This thermostat is pre-wired to two electrical connectors. Both the thermostat supply and control wiring can be quickly attached (plugged in) to the thermostat. 6795C4351 35' thermostat cable with connector plugs for termination at both the heat pump and electronic thermostat. 3.
. GENERAL INFORMATION The 6535 series package heat pumps are intended only for installation by RV manufacturers. The units are for “off the roof” installations and will usually be installed under the floor of the vehicle.
the chemical degradation of the surfaces they collect on. When suspending the unit from flooring or frame members, a minimum of four threaded rods are required. Minimum rod diameter is 5/16". The support rods and hardware must be plated or equivalently protected against corrosion. All threaded fasteners should be provided with lock washers, “locktite”, “double-nutted”, or equivalently protected from vibration loosening after installation.
GUIDELINES FOR SUPPLY AIR DUCTING Should the return air filter and filter retainer be located in the floor, a traffic duty grille will be required. The return air filter should be located in an area where: Minimum free area inside the supply duct is 48 square inches. Ducting with more free area than 48 square inches will improve system performance and vehicle cool down time. To decrease restriction and increase air flow, the ducting should make as few bends and turns as possible.
9. 115 VAC ELECTRICAL WIRING 1. WARNING - SHOCK HAZARD 3. To prevent the possibility of severe personal injury or equipment damage due to electrical shock, always be sure the electrical power is disconnected or off before beginning installation. 2. High Voltage Wiring Specifications A) U.L. approval requires the power supply to be copper conductors only with minimum #12 AWG.
CENTERED IN CLAMP BEFORE TIGHTENING IT. DO NOT OVERTIGHTEN!! THIS COULD RESULT IN PINCHING THROUGH THE PLASTIC WIRE INSULATION AND CAUSE SHORTING OR “HOT” WIRES TO GROUND (SHOCK HAZARD). THE CLAMP IS INTENDED FOR STRAIN RELIEF OF THE WIRES, SLIGHT PRESSURE IS USUALLY SUFFICIENT TO ACCOMPLISH THIS. 6. Circuit 1 and 2 Origination Points When both cooling systems (stage 1 and 2) cannot be powered from a single shore line, then the system must be wired as follows: A.
The thermostat 9 pin receptacle mates with a receptacle on one end of the RV Products 35' pre-wired thermostat harness. See component match-up section for harness part number and description. the wires required for operating the heat pump and quick connect receptacles for both the thermostat and the heat pump connections. At the thermostat, the connection is completed with a square 9 pin receptacle that slides together and snap-locks in place.
. CHECKOUT 1. 2. Before engaging power to any system, insure the following: A) All tools have been removed from the equipment. B) All wiring is attached, routed and properly secured. C) All panels (both mechanical and electrical) are in place. D) The thermostat system switch is placed into the “OFF” position and fan switch is placed in the “Auto” position. E) All co-workers have been warned that the equipment is being energized. 3.
