SHURflo Blaster Series User manual

BLASTER
SERIES WASH-
DOWN PUMP
SHURflo's Blaster series pumps are designed to handle the harsh
marine environment. Blaster motors have precision ball bearings
supporting the armature. Each motor is protected by an integral thermal
breaker, and are all U/L Marine listed. Blaster pressure switches are
sealed and the motors are finished with a baked-on polyurethane
coating to inhibit corrosion. The "Pro-Blaster" motor is sealed in an
exceptionally tough epoxy powder coated finish, allowing it to be in
environments where "splashed water" may be present. Blaster series
pumps are enclosed to prevent incidental moisture from entering;
however, they are not submersible units.
The Blaster delivers water on demand. With the spray nozzle off (output
side closed) the pump will turn off. As the nozzle is opened the pressure
within the hose (output side) drops. Once the pressure drops below a
predetermined point the pumps pressure switch closes and the pump
operates. With the nozzle set at a fine mist the pump will cycle, as it is
able to pressurize the hose faster than water being released. If the spray
nozzle is held wide open the pump will operate continually. The pump
may momentarily operate even after the nozzle is closed, as it
pressurizes the hose. Once the pressure setting is reached the switch
opens and the pump stops.
DUTY CYCLE
Wash-down pumps are rated for intermittent duty (only), as they operate at higher than average pressures. Operating a pump continuously for more
than twenty (20) minutes, within an hour period, is not recommended. Actual duty cycle is determined by amp draw, temperature, and rate of cycling.
NOTE: Rapid cycling should be minimized to ensure long life. Rapid cycling is defined as ON/OFF within two seconds.

MOUNTING
• Consider a dry location that allows easy access
if maintenance is required. The pump should
not be located in an area of less than one cubic
foot 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 operation.
• Mount higher than the outside water (sea)
level. The pump is capable of a 6 ft. [2M]
vertical prime above the outside water level.
The pump can be mounted in any position. If
mounting the pump vertically, the pump head
should be in the down position.
CAUTION: Do not drive screws through the
vessel's hull.
• Use #8 stainless steel hardware to fasten the
pump. Choose a solid surface (bulkhead or
stringer) that will not amplify pump sound. The
mounting feet are intended to isolate the pump
from the mounting surface; over-tightening,
flattening, or oversized screws will reduce the
mounting pads ability to isolate vibration/noise.
ELECTRICAL
• The pump should be on a dedicated
(individual) circuit protected on the positive (+
red) lead with the proper size "slow blow"
fuse. For all 12VDC pumps use a 15 amp
fuse, on 24VDC pumps use a 10 amp fuse.
The total current draw on the circuit must not
exceed 15 amps.
INSTALLATION AND OPERATION MANUAL

• An ignition protected switch (U/L approved
marine duty) rated at or above 15 amps is
recommended, and must interrupt current flow
on the positive (+ red) lead.
CAUTION:Use of "open" type switches (not ignition
protected) may cause an explosion of fuel vapors.
• Wire size (gauge/Mm2)is based on the distance
from the power source to the pump. The
minimum recommended wire size is #14 gauge
[2.5Mm2]. For lengths of 20-50 ft.[6-15M]use #12
gauge [4Mm2].
• The pump must be grounded to a "known
ground" (battery). The ground wire must be
the same size as the positive wire.
PLUMBING
• SHURflo swivel 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. Always secure barb tubing
connections with properly sized stainless steel
clamps to prevent leaks. Retail pump kits
include two ¾" swivel barb fittings (straight/
elbow) and an adapter to connect a standard
garden hose to the pump outlet fitting.
• Avoid any sharp radius in tubing that may kink
over time. Route tubing away from any heat
(exhaust manifolds etc.) and fasten securely.
• Inlet tubing (½"I.D. min.) from the sea-cock
valve to the pump should be rated for
vacuum. If rigid pipe is utilized, SHURflo
recommends that the pump inlet port be
plumbed with 1 ft. [.3M] of flexible 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 1ft. [.3M]length of flexible high
pressure tubing is suggested.

STRAINER / FILTRATION
A wash-down 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. Screen with a maximum hole
size of .025" [0.6mm] (#40 mesh) with a total
filtration area of 7 sq. in. [45 cm2]or larger provides
sufficient capacity under most on 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 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:
• 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.
• Always use high quality non-corrosive fittings, valves and hardware to assure long term reliability.
• 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.

TROUBLESHOOTING
Vibration induced by sea conditions or transporting may cause plumbing or pump hardware to loosen. Check for system components that are loose.
Many symptoms could be resolved by simply tightening. Check the following items along with other particulars of the system.

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 wash down system. To properly
drain the system perform the following:
1.Turn OFF power 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 hose
spray nozzle 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.
• If fuel vapor is detected never operate the engine
or electrical equipment, until the source is located
and/or properly vented.
• Electrical connections should be soldered and
insulated to prevent shorts and corrosion. Wiring
should be routed away from areas prone to water
and excess moisture.
• Be a responsible boater, don't pollute our oceans
and waterways.
