SHURflo Potable Water Pump Installation And Operation Manual

POTABLE WATER PUMP
Installation and Operation Manual
SHURflo has supplied pumps to the manufacturers of RV's for
over 30 years. Our patented Tri-a-fram
pumps deliver smooth, consistent flow at all ranges of operation,
while drawing low current. The balanced diaphragm design
incorporates two precision ball bearings for long life.
SHURflo pumps are 100% tested for proper operation before
they leave the factory. When installed correctly, SHURflo
water pumps will provide years of quiet operation.
A SHURflo pump in combination with a low back pressure
water system can exceed all expectations. For unmatched
reliability and trouble-free performance request SHURflo's
complete line of water system products.
GENERAL INFORMATION
SHURflo realizes 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 of a
6 ft. [1.8 ] vertical prime. Horizontal inlet tubing
M
will allow priming to 30 ft. [9
M
●
Consider a location that allows easy access
if maintenance is required. The pump should
not be located in an area less than one cubic
foot unless adequate ventilation is provided.
Excessive heat may trigger the integral
thermal breaker and interrupt
When the temperature drops the breaker will
automatically reset and start operation.
●
The pump may be mounted in any position. If
mounting the pump vertically, the pump head should
be in the down position so that in the unlikely event
of a leak, water will not enter the motor.
● #
Use 8 hardware to fasten the pump. Choose
a solid surface
(thick plywood)
amplify pump operation. 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.

●
Rapid cycling may be caused by excessive
back pressure created by one or more of the
following within a plumbing system:
Water filters not on separate feed lines.
Flow restrictors in faucets and shower heads.
Small I.D. lines. Pipe/tubing should be at
least ½"

Restrictions in a plumbing system may cause the
pump to rapid cycle

to prevent pulsating flow, and to achieve
maximum pump life.
To determine if adjustment is necessary, turn a
faucet to lower than average flow of water.
