CENTERED IN CLAMP BEFORE
TIGHTENING IT. DO NOT OVER-
TIGHTEN!! 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.
IF OTHER THAN NON-METALLIC
CABLES ARE USED FOR SUPPLY
CONDUCTORS, APPROPRIATE
STRAIN RELIEF CONNECTORS OR
CLAMPS SHOULD BE USED.
IN NO CASE SHOULD CLAMPING
OR PINCHING ACTION BE APPLIED
TO THE INDIVIDUAL SUPPLY LEADS
(NEUTRAL AND “HOT” WIRES).
D) The installer must form a drip loop in the
high voltage wiring routed between the
“Rain Tight” electrical fitting and the high
voltage terminal board wiring lugs. Do not
allow excess wiring to contact electrical
terminals, sharp screw ends or edging that
can cut or damage the wiring insulation.
E) After connecting the ground wire to the
grounding lug, verify that the ground wire
(which in some instances will be bare
copper) cannot come into contact with any
high voltage terminal.
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. Connect “CIRCUIT 1" to the circuit that is
powered from the vehicle shore line. This
allows stage 1 cooling to operate anytime
the shore line is connected to either the local
utility or the on-board generator.
B. Connect “CIRCUIT 2" to the circuit that is
powered from the on-board generator.
When wired in this fashion, stage 2 cooling
will operate only when the on-board
generator is in operation.
C. DANGER - SHOCK HAZARD
TO PREVENT THE POSSIBILITY
OF SHOCK INJURY FROM
APPLIANCE OPERATION:
THE WHITE WIRE MUST BE
CONNECTED TO NEUTRAL IN THE
SERVICE BOX ENTRANCE AND THE
MECHANICAL GROUND MUST BE
CONNECTED TO A GROUNDING
LUG EITHER IN THE SERVICE BOX
OR THE MOTOR GENERATOR
COMPARTMENT.
10. THERMOSTAT AND 12 VDC WIRING
THERMOSTAT OPERATING AND WIRING
REQUIREMENTS
The 6535 series heat pump is designed to be operated from an
RV Products electronic wall mounted thermostat. See
component match-up section for thermostat part number and
description. The thermostat is designed to operate 12 VDC
controlled heating and air conditioning systems. The
thermostat must be operated from a 12 VDC power source.
Maximum thermostat output for any load including the furnace
control wire must not exceed one amp.
The thermostat is equipped with a replaceable fast-acting 2
amp fuse located on the base of the thermostat. The fuse is
designed to open if the furnace is mis-wired or there is a short
in the system. Before replacing fuse, the cause of the failure
must be located and corrected.
IMPORTANT
Current draws in excess of one amp or
shorting any thermostat wires can cause
permanent thermostat failure.
The installer must provide the power source used to operate
both the thermostat and its control circuits. This power source
must provide one amp of continuous current at
12 VDC.
The thermostat is pre-wired at RV Products with two quick
connect electrical receptacles. There is one 9 pin receptacle
carrying the control wires required to operate the heat pump,
and a 3 pin receptacle carrying the two power supply leads and
the one furnace control lead.
