PLUMBING
•
SHURflo swivel hex/barb fittings provide easy removal if maintenance or access is required. The
fittings are designed with a "taper-seal", creating a water tight connection when
hand-tightened
¼
turn after contact. Always secure barb tubing connections with properly sized stainless steel clamps to
prevent leaks. For connecting to the pumps 1/2" threaded ports SHURflo supplies taper-seal swivel-
barb fittings for various tubing sizes.

•
Inlet tubing (1/2"I.D. min.) from the sea-cock valve to the pump should be rated for vacuum. If rigid
tubing or pipe is utilized, SHURflo recommends the inlet port be plumbed with a minimum of 1 ft.[.3
M
]
of flexible vacuum rated tubing. Standard garden hose is not suitable as inlet tubing as it may collapse
under vacuum, reducing water flow.
•
The pump outlet port
should not
be connected to rigid (plastic) pipe. Normal oscillation of the pump
may transmit through rigid plumbing causing noise and possibly loosen or crack components. A
minimum of 1 ft.[.3
M
] length of flexible high pressure tubing is suggested. Avoid any sharp radius in
tubing that may kink over time. Route tubing away from any heat (exhaust manifolds etc.) and fasten
securely.
RAW WATER STRAINER
A bait system is only as dependable as the water available to pump. A strainer with adequate capacity to
trap debris
must
be part of the system. Using #50 mesh or larger provides sufficient capacity under
most conditions. The interval for cleaning will be determined by the amount of debris encountered.
Check the strainer before and after each use.
Failure due to debris in the pump will not be covered
under warranty.
CAUTION:
The strainer
must
be mounted above the outside water line to prevent water from siphoning during
cleaning, without closing the sea-cock valve. Mount the strainer where it can be inspected and
cleaned easily.
NOTES & CAUTIONS
•
To prevent cavitation, through hull fittings should be located at least 12 in. off the center line of the
water pick-up for the motor.
•
The through hull fitting should have a sea-cock valve to shut-off in case of an emergency.
•
Double clamp all tubing connections that are below the water line.
•
Always use high quality non-corrosive fittings, valves, and hardware to assure long term reliability.
•
Electrical connections should be soldered and insulated to prevent shorts and corrosion. Wiring should
be routed away from areas prone to water, excess moisture, and heat. Properly seal all pipe threads
before the strainer to prevent unforeseen leaks.
Never
use Teflon tape or sealing compounds on pump
threads. Sealer may enter the pump causing a failure not covered under warranty.
WINTERIZING
If water is allowed to freeze in the system, serious damage to the plumbing and pump may occur. Failures of
this type will void the warranty. The best guarantee against damage is to completely drain the system as
follows:
1.
Turn power
OFF
to the pump. Close the sea-cock valve at the through-hull fitting. All water in the inlet tubing
should be drained.
2.
Remove both inlet/outlet port connections at the pump and drain the tubing.
3.
Turn the pump
ON
and allow water inside the pump to be purged.
It is recommended that the pump's inlet/outlet port not be reconnected.
4.
Make a note at both the sea-cock valve and bait tank that the "Plumbing is Disconnected".
GENERAL SAFETY PRECAUTIONS
•
When the vessel is not in use, the main power switch and sea-cock valves should be
OFF
. However, if
left afloat the bilge pump should still have power. Never operate the engine or electrical equipment if
fuel vapor is detected until the source is located and/or properly vented.
