TURN OFF TWO-WAY RADIO. Obey all signs and instructions.
EXPLOSION
ELECTRICAL BLASTING CAPS or in a BLASTING AREA or in areas
Explosive atmospheres are often, but not always, clearly marked. They
include fueling areas, fuel or chemical transfer or storage facilities:
areas where the air contains chemicals or particles, such as grain,
dust, or metal powders, and any other area where you would normally
be advised to turn off your vehicle engine.
INSTALLATION
CAUTION
• Disconnect power to the power relay module prior to HiPot testing
of the camper or the microprocessor will be damaged.
1. Install the power relay module in a clean, dry interior area protected
from moisture. Use the four (4) 5/32˝ diameter holes for mounting the
module base. Position the base on the mounting surface and secure
it using appropriate hardware for the wall material. Orient antennae
in the position shown (
mounting surface with appropriate hardware (FIG 5-P).

CAUTION
• Failure to orient antennae properly will result in intermittent opera-
tion of the wireless remote system.
NOTE: Correct polarity must be observed as noted on the circuit board
next to 5 & 6-H. The unit will not function if the input power is installed
in reverse polarity. See FIG 5 & 6.

2. SUPPLY POWER TO UNIT: The unit operates from a +12 VDC battery and must
be supplied through a 40 AMP circuit breaker (FIG 5E & 6-E). Route the
#8 AWG, +12 VDC from the circuit breaker and the ground wiring, to the
terminal block (FIG 5H & 6-H).Terminate the wires in the labeled positions and tighten the screws with 16-18 in-lbs of force.
3. Route the two #10 AWG wires from each jack to the terminal block 5-I
& 6-I. Refer to the labels next to each terminal position for driver front,
passenger front, driver rear, and passenger rear jacks. Terminate the
wires for each jack and tighten the screws with 12-13 in-lbs of force.
4. Install the Activation Switch near the floor just inside the door of the
pickup camper (
Plug the flat cable into the left side of the power relay module (FIG 5-J &
6-J) and route to the location of the activation switch (
other end of the cable into the back side of the activation switch.
NOTE: The Key Fob control has an Activate/Learn button on the relay mod-
ule instead of a separate Activation Switch.

WARNING
PERSONAL INJURY & PRODUCT DAMAGE
• Do not replace or charge batteries in a potentially explosive atmos-
phere. Contact sparking may occur while installing or removing batteries and cause an explosion.
• All batteries can cause property damage and/or bodily injury such
as burns if a conductive material such as jewelry, keys or beaded
chains touches exposed terminals. The material may complete an
electrical circuit (short circuit) and become quite hot. Exercise care
in handling any charged battery, particularly when placing it inside a
pocket, purse or other container with metal objects.
LARGE REMOTE BATTERY INSTALLATION:
1. Firmly slide battery cover (remote back) down to remove.
2. Insert one 9V battery.
3. Replace the battery cover and slide up until secure.
The battery type is 9V alkaline battery which will provide approximately
45 minutes of continuous use.
KEY FOB BATTERY INSTALLATION:
1. Using a Phillips small tip screwdriver, remove the screw at the bottom
of the key fob remote.
2. Using a standard (thin) blade screwdriver carefully pry apart the two
halves of the remote case.
3. Carefully lift the front half of the case away from the bottom case to
expose the circuit board and battery.
4. The battery is type 23, (12 volt). Remove the battery from the holder
making note of the polarity. Install the new battery into the case and
re-assemble the enclosure and install the screw.
NOTE: Remove batteries before storing your remote for extended periods.
Batteries corrode over time and may cause permanent damage to
your remote.
DIP SWITCHES
The wireless remote and power relay module are equipped with dip
switches. For the unit to operate, the switches in both units must be set
to the same code.
NOTE: The code for all units is preset at the factory prior to delivery. If
you frequently camp next to other RV’s equipped with the Atwood
remote control set the remote and power relay to a unique code to
avoid actuating other campers near you.
TO SET DIP SWITCHES:
NOTE: Key Fob does not have dip switches.
POWER RELAY MODULE - Determine a code and record it. Locate the dip
switches (FIG 4-K & 6-K). To set the dip switches, slide the individual dip
switch to the up position which is ON or keep in the down position
which is OFF. Dip switches can be moved easily with a ball point pen or
other small pointed instrument.
REMOTE - Using a phillips screw driver, remove the four screws in the
four corners of the remote. Take off the back cover to expose the dip
switches (
FIG 4-A insert). Set the dip switches to the same code as the
power relay module. Replace the back cover and install the four
screws. Ensure the screws are evenly tightened.
OPERATION
WARNING
• Park the camper on a firm, level site.
• Area below and around jacks must be clear of obstructions.
•
Do not place blocks under the jack for additional ground clearance.
• Always keep the front of camper higher than or equal to the rear
of the camper. Never allow either side or end of camper to be more
than 4˝ out of level (
• Maintain proper load distribution and a safe distance when
raising/lowering coupler.
1. Remove the hand held remote control from its secure compartment.
2. Press Activation Switch or Activate/Learn Button. The switch has an
automatic off circuit that times out after 10 minutes.
3. When finished, the LED on the activation switch must not be lit.
CAMPER CAN TIP OVER
FIG 2 and 3).
CAUTION
• Do not over-extend or over-retract jacks. The electric jack has an
internal slip clutch to help prevent damage; when clicking sound is
heard, release switch. Continuing to hold the switch will wear out the
slip clutch or cause damage to the motor.
