SHURFLO RV FRESH WATER
PUMP
INSTALLATION AND OPERATION
Shurflo’s patented RV Fresh Water Pumps for
drinking water were developed to delivery
smooth, consistent flow at all ranges of
operation, while drawing low current. The
balanced diaphragm design incorporates
precision ball bearings for long life. Each
motor is equipped with an integral thermal
breaker and all units are CE approved. RV
fresh water pumps are enclosed to prevent
incidental moisture from entering; however,
they are not intended for environment where
splashed water is present. When installed
correctly, RV Fresh Water Pumps provide
years of quiet operation.
General Information
Shurflo water pumps meet the essential
health and safety requirements and are in
conformity with the EU EMC directive
89/336/FEC as specified in EN 55014 (1993).
Shurflo realises that in many instances our
pump is being installed as a replacement
pump within an existing system. The
following guidelines should be considered to
achieve optimum pump operation.
Mounting
The pump can be at the same level or below
the water tank. It may be positioned above
the water tank if needed, as it is capable or a
6 ft. (1.8m) vertical prime. Horizontal inlet
tubing will allow priming to 30 ft. (9m).
The pump should not be located in an area
of less than one cubic foot (0.03m) unless
adequate ventilation is provided. Excessive
heat may trigger the integral thermal breaker
and interrupt operation. When the
temperature drops, the breaker will
automatically reset and start the operation.
The pump may be mounted in any position.
The mounting feet are intended to isolate the
pump from the mounting surface; over
tightening, flattening, or use of oversized
screws will reduce the ability to isolate
vibration/noise.
Winterizing
If water is allowed to freeze in the system,
serious damage to the plumbing and the
pump may occur. Failures of this type will
void the warranty. The best guarantee
against damage is to completely drain the
water system. However, non-toxic antifreeze
for fresh water, available at local RV centres,
may be used.
CAUTION: Do not use Automotive
Antifreeze to winterize drinking water
systems. Such solutions are highly toxic.
Ingestion may cause serious injury or
death. To properly drain the system
perform the following:
Drain the water tank. If the tank doesn’t
have a drain valve open all taps allowing the
pump to operate (15min. ON. 15 min. OFF)
until the tank is empty.
Open all the taps (including the lowest valve
or drain in the plumbing) and allow the pump
to purge the water from the plumbing, then
turn the pump OFF.
Using a pan to catch the remaining 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
pump plumbing. Make a note at tank filler
as a reminder: “Plumbing is Disconnected”.
