Planning the installation ("AQUAJET ES SERIES" ONLY):
The Aquajet ES Series was designed specifically for the RV aftermarket and, as a result, should be
compatible with the existing electrical wiring for most RVs. Because the Aquajet ES Series uses a
lower amperage motor than the Aquajet RV Series, installation is generally simplified. Oftentimes,
installation is as simple as removing the wirenuts connecting the existing water pump and then
reconnecting the existing wiring (keeping careful track of polarity) to the Aquajet ES.
Before installation, however, you should insure that your particular RV does not require any electrical
modifications to run the Aquajet ES, as follows:
1. Determine whether or not your existing wiring can supply 6.5 Amps to the Aquajet ES without
generating an excessive voltage drop or overloading any control component. You should check
specifically for three (3) things:
a. Determine whether your RV is currently using an Intellitec pump controller. The Aquajet
ES Series is compatible with most common rated versions (7 Amp, 10 Amp, 15 Amp).
However, if you have either a 3 Amp or non-rated contoller, you should procure a 30 Amp
rated relay to augment your existing controller. These 30 Amp relays are available through
local automotive stores or through Aquatec directly (P/N 20-267).
If necessary, please refer to Diagram 8 at the back of this User's Guide for additional infor-
mation.
b. Check your RV Owner's Manual for the recommended fuse rating for the pump branch cir-
cuit. If your recommended rating is rated 10 Amps or more, you can proceed directly with
the electrical installation. If your recommended rating is less than 10 Amps, you should
procure a 30 Amp rated relay as referenced above.
If necessary, please refer to Diagrams 1 and 2 at the back of this User's Guide for addi-
tional wiring instructions.
c. If there are two (2) or more switches in your RV which independently control your pump,
you may experience excessive voltage drops in your existing circuitry. Using voltmeter,
test voltage at the pump with the pump running (refer to Diagram 1 at the back of this
User's Guide). With either a fully charged battery or a running generator, you should be
getting at least 11 volts at the pump. If not, you should procure a 30 Amp rated relay as
referenced above.
2. Determine the optimal location for the Aquajet ES. If possible, plan to position the Aquajet pump
horizontally, with its rubber feet resting on a "floor-like" surface rather than mounted on a wall.
Take into consideration the 1/16 hex adjustment screw on the Aquajet pump-head so you have
access to it after the installation.
Never mount the pump in an area where gasoline vapors
are present, as the motor and heatsink of the speed-controller may get hot (up to 200 F)
after extended running.
Locate the Aquajet ES at least one inch away from any wall surface. In
most cases, you'll be able to mount the Aquajet ES very close to where the old pump was locat-
ed.
