Installation:
1. Using Voltmeter, determine polarity of the wiring to the existing pump(s).
Unfortunately, there is no standardized color scheme for RV wiring (most RVs , however, seem to
use red for the positive lead and black for the negative lead). Regardless of your specific config-
uration, positive voltage (12VDC) must be connected to the RED (fused) leadwire of the Aquajet
RV. Reversing this polarity will instantly blow the in-line fuse and may permanently damage the
controller. Mark the positive (hot) RV wire with a piece of tape.
2. Turn power "off" to existing pump(s).
3. Open a faucet, bleed off all existing pressure, then close the faucet again.
4. Disconnect the main power to the pump (either at battery or fuse panel).
5. Remove the wire-nuts from the leads to the old pump.
6. Steps 1 and 2 of the earlier 'Installation Planning' section should have determined the applicable
wiring method. As appropriate, wire the Aquajet pump as per Schematics 1, 2, 3, 4 or 8
7a. [For old pump outlets connected to hose, as in Figure 5]
Insert O-ringed end of (Qest) threaded adapter into outlet port (marked with arrow pointing away
from pump) of the Aquajet pump. Lock fitting in place by pushing down retainer slide.
7b. [For old pump outlets directly connected to hard tubing, as in Figure 6].
Insert the O-ringed elbow fitting of the Accuflex hose adapter (sold separately) into the outlet port
of the Aquajet pump. Lock fitting in place by pushing down retainer.
8a. [If the Aquajet pump is to be directly plumbed to the existing inlet filter/fitting, as in Figures 5 and
6]
Insert the O-ringed end of threaded adapter into inlet port (look for arrow pointing towards the
heatsink of the controller) of the Aquajet pump. Lock fitting in place by pushing down retainer
slide.
8b. [If the Aquajet pump is to be remote mounted, as in Figure 7]
Insert the O-ringed elbow fitting of the Accuflex hose adapter (sold separately) into the inlet port
of the Aquajet pump. Lock fitting in place by pushing down retainer slide.
9. Remove the mounting screws from the old pump.
10. Place a towel under the inlet port (suction side) of the existing pump(s) and quickly remove the
connecting fitting/filter.
11. Re-attach the filter/inlet fitting to the applicable adapter on the inlet side of the Aquajet pump.
