Please read the following instructions before attempting an installation.
When properly installed, Aquajet Series pumps can be used in virtually
any existing RV.
If you prefer to have the pump professionally installed, contact Remco
(763-253-4743) to locate your nearest authorized service center.
WARNING
The 5-chamber Aquajet Series pumps are more powerful than most
existing RV water pumps and, as a result, may draw more current
(Amps) than the pump(s) they replace. It is imperative that any power
supply, fuses/circuit breakers, wiring, switches, connectors, or
controllers that are used to supply 12 VDC to the pump are adequately
sized. Inadequately sized components may overheat, causing an
electrical fire.
When installing an Aquajet Series pump, positive voltage (+12VDC)
must be connected to the Aquajet's red fused leadwire. Reversing
polarity will instantly blow the fuse and may permanently damage
the controller.

If you are uncertain with respect to any of this information, Remco
highly recommends that a qualified technician perform your installation
and determine the existing polarity of your current wiring.
Safety Tips
1. Never operate the pump in an atmosphere where flammable gases
may be present, since arcing at the motor brushes or switch
contacts may cause an explosion.
2. After extended operation, or if malfunctioning, metal surfaces of
the pump may become hot and cause burns if touched. If this
occurs, disconnect electrical power and wait 30 minutes before
touching pump.
3. Never mount the pump where the surface temperature of the motor
or the controller (200 F maximum) may cause ignition of the
surrounding materials.
4. Do not wrap the pump with an insulating material or enclose it so
tightly that air circulation around the pump is prevented. The pump
will generate approximately the same amount of heat as a 75 watt
lightbulb.
5. The pump should be mounted in a dry location away from any heat
source(s).
6. Pumphead materials are designed for use with potable water only
and should never be used with petroleum products.
7. The pump is equipped with a pressure sensing demand switch
which controls the maximum operating pressure as set at the
factory. Never subject the pump to pressures above 90 PSI
maximum.

8. Always consider electrical shock hazards when working with and
handling electrical equipment. If uncertain in your abilities, please
consult an electrician.
9. 55Aquajet ORV, OES, ARV and AES Series pumps are equipped
with an automatically resetting thermal protector. If a pump is not
running, it may restart at any time.
10. Both the 55Aquajet ARV and AES Series include a fuse-holder.
It is important to use only a 15 amp AGC automotive type fuse for
the Aquajet RV Series and a 10 amp AGC fuse for the Aquajet ES
Series. Once again, use only these types of fuses with these
specific pumps.
11. It is necessary to use a screen filter between the water holding tank
and the pump to prevent debris from entering the pump. Particulate
matter may cause the valves inside the pump to stick open. This
filter needs to be cleaned on a regular basis, or it will restrict water
to the pump.
12. Winterizing the pump: If water is not drained from the system
during freezing temperatures,damage to the pump and the
plumbing is likely:
a. Drain the water holding tank.
b. Open all faucets and run the pump to expel all water.
c. Disconnect inlet and outlet fittings and run pump to remove
residual water from the pump.
d. Leave fittings disconnected from pump.
Installer qualifications
If you intend to install an Aquajet Series pump without professional
assistance, you should clearly be “handyman” competent enough
to do simple low voltage electrical wiring, crimp connectors, obtain
voltage measurements, understand polarity as well as schematics
which illustrate relay connections. Additionally, you should be
comfortable with water system plumbing, installing hose clamps,
using Teflon tape, and removing/re-tightening compression fittings.

A typical Aquajet installation takes between 1 - 2 hours and requires
the following:
Basic Tools
Flashlight, Voltmeter, Wire Stripper/Crimper, Standard Screwdriver,
Phillips Screwdriver, Hose cutter, 8˝Crescent Wrench, bucket, towels.
Depending on the RV’s layout, electrical and plumbing configuration,
additional hardware may be needed for a successful pump installation.
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 location 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
(“55AQUAJET ORV and ARV 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 controller 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 vehicles, 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:

9. ELECTROMAGNETIC INTERFERENCE a. Replace it with a 10 or 15 Amp rated controller. For your
convenience, Intellitec’s phone number is [phone].
b. Procure a 30 Amp rated relay (through either a local automotive
store or directly through the Remco catalog, product number
20-267) to augment your existing controller. Please refer to
Figures 3, 4, page 14 and Figure 8, page 15.
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
distances, 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 nominal 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 pump (see Figures
1 and 2, page 13).

www.remcotowing.com | www.remcoindustries.com | REMCO INDUSTRIES 19
6REMCO INDUSTRIES | www.remcoindustries.com | www.remcotowing.com
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 approximate 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 pump at least
one inch away from any wall surface. In most cases, you’ll be able
to mount the Aquajet pump very close to where the old pump was
located.
4. Survey the existing plumbing and identify the suction line (i.e. the
line going from the water holding tank to the pump). For the
quietest possible operation of the Aquajet pump, 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, page 15), 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 possible pump operation. Remco
also offers, as an optional accessory, a 39˝long pre-assembled
hose with fittings (Remco product number 25-174) that will adapt
directly to the Aquajet RV and your existing plumbing. Please refer
to Figures 6 and 7, page 15.

4. PUMP DOES NOT PRIME
Planning the installation
(“55AQUAJET OES and AES SERIES” ONLY):
The Aquajet OES and AES Series pumps were designed specifically
for the RV aftermarket and, as a result, should be compatible with the
existing electrical wiring for most RVs. Because these pumps use a
lower amperage motor than the Aquajet ORV and ARV 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 pump.
Before installation, however, you should insure that your particular
RV does not require any electrical modifications to run the Aquajet
OES/AES, 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 controller, 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 Remco directly (P/N 20-267).
If necessary, refer to Figure 8, page 15 for additional
information.
b. Check your RV Owner’s Manual for the recommended fuse
rating for the pump branch circuit. 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 Figures 1 and 2, page 13 for additional
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 Figure 1, page 13). 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 pump. 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

as the motor and heatsink of the speed-controller may get hot
(up to 200 F) after extended running. Locate the Aquajet pump
at least one inch away from any wall surface. In most cases, you’ll

Aquajet pump and your existing plumbing. Please refer to Figures
6 and 7, page 15.
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
configuration, positive voltage (12VDC) must be connected to the
RED (fused) leadwire of the Aquajet pump. 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 Figures 1, 2, 3, 4 or 8, pages 13-15.
7a. [For old pump outlets connected to hose, as in Figure 5, page 15]
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.

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.
12. If an Accuflex hose adapter is used on the outlet side (see Figures
6 and 7, page 15), place the other end of the hose adapter up high.
This should stop water from being siphoned out.

15. Position the Aquajet pump into its intended mounting place.
16. Drive the mounting screws (Remco recommends #10 screws,
1.5˝long, to be used with washers) into the floorboard. Be sure
to stop just as the screw heads touch the washers so you do not
compress the rubber mounting grommets.
17a. [If you are plumbing per Figure 5, page 15]
Place a bucket under you plumbing system’s pressure hose,
have an assistant open 2 inside faucets and drain water from the
pressure line. Connect the pressure hose fitting to the Qest
adapter on the pump outlet side.
17b.[If you are plumbing per Figures 6 or 7, page 15]
Place the open end of the Accuflex tubing from the Aquajet outlet
port into the bucket.
18. Reconnect the main power to the pump/relay using fuse box
or battery.
19. Have an assistant briefly power up the pump using one of the
RV’s standard “pump switches”.
20. Water should be flowing into bucket (see Figures 6 and 7,
page 15) or into the sinks (see Figure 5, page 15).
21. Allow Aquajet RV to run for 10-15 seconds to get rid of all air
inside the pump, then power down the pump.
22. Coil the Accuflex outlet tubing (pulsation dampener) and connect
the pressure side Qest fittings. Use tie-wraps if necessary
to insure that the tubing will not rattle.
23. Power up the pump again and check for leaks. Tighten fittings
where necessary.
24. Close all faucets and wait for the pump to slow down and
eventually stop. If a continuous low ‘whining’ sound is heard from
the pump, re-check the voltage at the pump terminals (it should
be 10.5 V minimum). If necessary, use 1/16˝hex-key and turn the
pressure adjustment screw on the controller counter-clockwise.
25. Open the most commonly used faucet to a typical flow level.
Observe the pump - it should be running continuously at a low
speed. If the pump is “cycling”, use 1/16˝hex key to turn the
pressure adjustment screw on the controller clockwise. Return
to step 24 and verify that pump shuts off properly.
26. Your pump should now be ready for use. Power down the pump
when there is no need for water.

TEMPERATURE
The Aquajet RV Pump operates in the shaded area, and is therefor capable of sustaining continual running, at
any of the above listed pressures, without shutting down to allow the motor to cool. The Speed Controller gen-
erates heat much faster, as evidenced by the heat sink temperature rise and must be protected from accidental
human contact. The Speed Controller is equipped with a thermal protector that protects the electronic com-
ponents in case of extreme temperatures. After sufficient cool down, the system will re-start
ALL PERFORMANCE AND HEAT RISE FIGURES ARE APPROXIMATE. ACTUAL VALUES WILL VARY WITH AMBIENT CONDITIONS.
