Electrical Supplies: Relay, associated connectors, wire, electrical tape and mounting hardware may
be needed. For plumbing the pump to rigid (polybutylene or PEX) tubing, a flexible connector hose
is strongly recommended for the pressure side. If the Aquajet pump is mounted at a different loca-
tion than the old pump, flexible connector hoses will be required on both the inlet and outlet side. A
screen-filter should always be used between the RV water tank and the pump.
Planning the installation ("AQUAJET RV SERIES" ONLY):
1. Determine whether or not your RV is currently using an 'Intellitec' pump controller (i.e. three or
more "momentary" type switches which can be used to turn the pump on/off.). There are at least
four (4) different types of Intellitec controllers currently in use, but not all of them can be used
with the Aquajet RV.
Specifically, only a four terminal, 10 or 15 Amp rated Intellitec con-
troller can be used to directly control the Aquajet RV. Intellitec 7 Amp, 3 Amp or non-rated
controllers should NEVER be used to switch the load of the Aquajet RV.
The Intellitec controllers are typically located in the pump compartment (on some Fleetwood vehi-
cles, however, they are located near the circuit breaker panel under the refrigerator). Once
you've located the controller, before taking anything apart, make a sketch of the existing wiring
including the colors of the wires and how they are attached. If you do have an Intellitec controller
that does not say either "10 Amp" or "15 Amp" on the label, then you must either:
a) Replace it with a 10 or 15 Amp rated controller. For your convenience,
Intellitec's phone number is (708) 268-0010.
b) Procure a 30 Amp rated relay (through either a local automotive store or directly through
the Aquatec catalog, product number 20-267) to augment your existing controller. Please
refer to schematics figures 3, 4 and 8.
2. Determine whether or not your present wiring is capable of supplying 10 Amps without generating
an excessive voltage drop. For a 10 Amp load, 14 AWG can typically be used up to 10 ft dis-
tances, 12 AWG up to 20 ft distances, and 10 AWG for distances of more than 20 ft. You can
also determine if your wiring is adequate by using a Voltmeter, as follows:
a) Probe inside the wirenuts that connects the existing pump.
b) Write down voltage at pump with all valves closed and pump inactive. This is your nomi-
nal battery voltage.
c) Open a faucet or faucets so you get the pump running continuously.
d) Measure the voltage again at the pump wirenuts.
e) Note the running voltage.
f) Subtract the running voltage from the nominal voltage. This is your "voltage drop".
If the voltage drop with your existing pump (typically 5 Amps) exceeds 1 Volt you will need to pull
a new heavier (10-12AWG) 'hot' wire to the pump AND use a 30 amp relay (referenced in section
1b above) to connect your Aquajet RV (see figures 1 and 2).
