Typically, if your RV uses one (1) switch to control the pump, the wiring is short and should prove

sufficient. If your RV has two (2) rocker-style switches you will see significant voltage drops and

thus both the relay and the new heavier "hot wire" will be required.

Locate the battery and the fusebox for the pump. Identify which fuse protects the pump.

Determine which source of power from which it will be simplest to pull a hot wire to the pump.

Plan the routing of the wire and aproximate the length of wire required.

3. Determine the optimal location for the Aquajet RV. 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 RV at least one inch away from any wall surface. In

most cases, you'll be able to mount the Aquajet RV very close to where the old pump was locat-

ed.

4. Survey the existing plumbing and identify the suction line (i.e. the line going from the water hold-

ing tank to the pump). If there is not a screen-filter currently on this line, then one should be pro-

cured for the Aquajet installation (several brands are available at any local RV dealer). For the

quietest possible operation of the Aquajet RV, you should try to isolate the pump mechanically

from your RV's typically hard Polybutylene or PEX tubing. If your RV is currently plumbed with

soft-walled, reinforced hose (see Figure 5), then your system should be perfectly sufficient as is.

By installing a piece of IAPMO approved cold water hose (such as 'Accuflex' Series 136)

between the pump outlet port and your RV's hard plumbing, you will achieve the quietest possi-

ble pump operation. Aquatec also offers, as an optional accessory, a 39" long pre-assembled

hose with fittings (Aquatec product number 25-174) that will adapt directly to the Aquajet RV and

your existing plumbing. Please refer to Figures 6 and 7.

5. At the end of your survey you should have determined how to wire the Aquajet pump. Your alter-

natives are illustrated in Figure 1 ("no change", also applicable for single switch systems), fig2,

fig 3 , fig 4 or fig 8. You should also have determined how to plumb the pump. Your options are

fig 5, 6 or 7. Always make sure you have all hardware needed before you start the actual

installation.
