ELECTRICAL
❚ The pump works best on an individual
filtered circuit, protected by the recom-
mended fuse or breaker specified on the
label.
❚ A 15-Amp switch is recommended and
should be on the positive lead (red wire).
❚ Wire Sizing: Proper wire sizing is
required for good pump operation. If the
wire is too small, low voltage will affect the
pump performance and can create a fire
hazard. SHUT OFF POWER TO THE PUMP
WHEN LEAVING THE RV UNATTENDED.

Minimum Wire Size for a 10% voltage drop on a 12VDC, 15 Amp
Circuit. Length is the distance from the power source to pump
and back to ground.
PLUMBING
Installation of a strainer is required to
prevent debris from entering the pump.
For noise and vibration reduction we
recommend at least 18 in. [.5 M] of
1/2" [13mm] I.D. flexible high-pressure
hose to both ports. The pump ports and
strainer should not be connected to
plastic or rigid pipe. This hose should
be anchored where it meets the hard
plumbing to reduce plumbing vibration.
OPERATION
This pump is designed for intermittent
duty only. The pump operates normally
up to about 40-psi, where a spring-load-
ed by-pass valve opens, allowing flow
back from the output side to the input
side, providing smooth, steady flow with
virtually no cycling, all the way down
to a trickle. As a faucet is opened back
up, the pressure will drop, the by-pass
will close and full flow is again ob-
tained. This allows good flow, even with
today's restrictive showers and pullout
sprayer faucets. Performance will vary,
of course, depending on the voltage to
the pump; lower voltage = lower flow,
higher voltage = higher flow. Remember
your electrical safety: It is always best to
shut power to the pump OFF when leav-
ing the RV unattended.

ABOUT THE BY-PASS
NOTE: By-pass adjustment should only
be performed by a professional techni-
cian with proper gauges and equipment.
The by-pass is a spring loaded dia-
phragm that opens up allowing water
from the discharge side back to the inlet
side. The by-pass is set to begin opening
at about 40 psi and creating full by-pass
at about 62 psi (lower pressure pumps
will vary depending on the by-pass and
pressure shut-off settings). The pres-
sure switch on the pump is set to shut
off at 55 psi. If the switch or by-pass
are adjusted too much, the by-pass and
switch shut-off can overlap and THE
PUMP WILL NOT SHUT OFF. Screw-

SANITIZING
[2.1]
[3.3]
Potable water systems require periodic
[5.3]
maintenance to keep components work-
ing properly and deliver a consistent
flow of fresh water. Sanitizing is recom-
mended: prior to storing, after a period
of storage, or any time the system is
opened or contaminated, as follows:
NOTE: Check your Vehicle Owner's
Manual for specific instructions.
By-pass any filters or remove filter
cartridges.
1. Determine the amount of common
household bleach needed to sanitize the
tank.
A) 2 ounces of bleach per 15 gallons
tank size: 60 gallon tank [15 x 4] = 4 x
2 ounces = 8 ounces of bleach.
B) I ml bleach per 1 liter tank size:
300 liter tank = 300 milliliters of
bleach.
WINTERIZING
Refer to the vehicle owner's manual for
specific winterizing instructions.
If water is allowed to freeze in the
system, serious damage to the plumb-
ing and pump may occur. Failures of
this type will void the warranty. The best
guarantee against damage is to com-
pletely drain the pump and perform the
following:
1. Drain the water tank. If the tank
doesn't have a drain valve, open all fau-
cets allowing the pump to operate until
the tank is empty.
2. Open all the faucets (including the low-
est valve or drain in the plumbing), allow
the pump to purge the water from the
plumbing, and then turn the pump OFF.
ing the switch screw in clockwise will
raise the shut-off pressure. Unscrew-
ing the switch screw counterclockwise
will lower the pump shut-off pressure.
Screwing the by-pass screw in will raise
the pressure at which the by-pass starts
and raise the full by-pass pressure.
Unscrewing the by-pass screw coun-
terclockwise will lower the pressure at
which by-pass starts and lower the full
by-pass pressure.
WARNING: If full by-pass is reached
before the shut-off setting, the pump
will not shut off. Full by-pass pressure
setting should be at least 10 psi higher
than pump shut off pressure.
2. Mix the bleach with water in a con-
tainer such as a gallon jug. If tank is
filled through a pressurized fitting, pour
the bleach into the hose before attach-
ing the hose to the city water entry.
3. Pour the bleach solution into the tank
and fill the tank with potable water. Rock
the RV back and forth to coat top and
sides of potable water tank.
4. Open all faucets (Hot & Cold) al-
lowing the water to run until the odor
of chlorine is detected. Allow four (4)
hours of contact time to disinfect com-
pletely. Doubling the solution concentra-
tion allows for a contact time of one (1)
hour.
5. Drain the tank. Refill the tank and
flush the system once or twice until the
odor has decreased. The residual chlo-
rine odor and taste is not harmful.
3. Using a pan to catch the remain-
ing water, remove the plumbing at the
pump's inlet/outlet ports. Turn the
pump ON, allowing it to operate until
the water is expelled. Turn OFF power to
the pump once the plumbing is emptied.
Do not reconnect the pump plumbing.
Make a note at tank filler as a reminder:
"Plumbing is disconnected".
4. All faucets must be left open to guard
against any damage.
5. Potable anti-freeze may be poured
down drains and toilets to protect
p-traps and toilet seals. Sanitize the
plumbing system before putting the
plumbing system back in service.
