CAUTION!
Never run the pump without water in
the pump case because lack of water
can damage the shaft seal.
W ARNING!
During periods when the pump is not in use,
and always during servicing, switch the
ON/OFF switch to OFF and pull the plug from the receptacle.
NOTE: THE PUMP SHALL BE SERVICED BY QUALIFIED PERSONNEL ONLY.
PIPING
The pump has m a l e / female sockets to receive 1-1/2" (38mm)
threaded fittings. Keep the piping as simple as possible, and avoid
connecting an elbow directly to the pump inlet (use a length of
straight pipe to allow a proper entry of the water). Keep as much of the
suction pipe as possible below the water level of the pool. This will
reduce the priming time but arrange the pipe to rise continuously
toward the pump to prevent high, spots that could form air pockets.
Support the pipes independently so that they do not place strain on
the pump. Install gate valves in the pump suction and pool return
lines close to the filter system for convenient servicing of the equip-
ment. These valves are essential if the equipment is installed below
water level. Keep the gate valve in the suction line fully open during
operation, and make sure that its gland is kept tight to prevent the
entrance of air around the valve stem. Take care during installation to
keep the pipes clean, and make sure that the suction system is absolutely
INSTALLATION
Locate the pump as close to the pool as possible, but keep at a
minimum distance of at least five feet (1.5M) to prevent it being used as
a means of access to the pool by young children (See previous
Warning). Locate the pump preferably in a dry, shaded, and well-venti-
lated area. Should it be impossible to put the pump at or below
water level, choose the lowest possible position. This simplifies
priming, and adds to the pressure developed by the pump. Prepare
a hard, level surface that is large enough to accommodate the associat-
ed equipment. Bear the following in mind: Drainage of the filter
room or pit; Ventilation of the motor; Access for servicing and winter-
izing the equipment; Protection of the equipment. Make sure the
bearing surface is leveled and straight to reduce vibrations.
This is a self-priming pump, which means that it can raise water to
itself through a dry suction line without using valves, provided the
pump case and strainer body are full of water before the motor is started.
We recommend the use of a swing check valve in the suction pipe, at or
below water level, if the suction lift is more than 5 feet (1.5m) or if the dry
suction line would be more than 10 feet (3.0 m) long. This arrangement
makes the initial priming easy and keeps the suction pipe primed at all
times. The pump is built from glass-reinforced thermoplastic mould-
ings. These eliminate all corrosion problems and insulate the water
passages from the electric motor. A closed impeller, which requires
no field adjustment to maintain efficiency, runs inside a multi-vane
s e p e r a t e diffuser . Ample running clearances between impeller
and case promote long life and prevent seizure should sand enter the
pump. The impeller hub forms an insulating sleeve over the motor shaft
and carries the mechanical shaft seal. This seal, which has a pure-car-
bon rotating face working against a ceramic seat, requires no
attention until leakage at the shaft shows that replacement is neces-
sary. For easy routine servicing, the built-in hair and lint strainer
has a transparent cover. For easy access to the working parts, the
removal of six screws allows the motor, bracket, seal, impeller and diffus-
er to be withdrawn as a unit. Anti Vibration Features have been added
to the splash cover and base resulting in a quiet running. SharkJet
assemblies were simplified for ease of maintenance and repair.
GENERAL
ELECTRICAL CONNECTIONS
Check that the information on the pump nameplate corresponds to
the power supply. Employ a competent electrician to make the wiring
installation in accordance with the local electrical code. Every motor
requires a fused disconnect switch. SHARKJET pumps are suitable for
115V only. SHARKJET pumps are equiped with a splash cover and a 25
foot (7.5m) three conductor cord ending with a three-pin grounding
For 2-speed pumps,
start and prime the pump at HIGH SPEED only. Do
not change to LOW SPEED before the pump is working properly. At HIGH
SPEED (3450 rpm approx.), the motor develops its full horsepower and
the pump generates high capacity and pressure. Use high speed for
maximum filtration at peak periods and whenever turbidity levels are
high. At other times switch to LOW SPEED (1725 rpm approx.). For
backwashing and vacuuming, HIGH SPEED is required. If the pump
is supplied as part of a complete filter system, follow the starting-up
procedure described in the separate instructions for the complete
filter system. In other cases, proceed as follows:
1).
Close the gate valves in the suction and return lines. Remove the
cover from the hair and lint strainer and fill the pump completely
with water. Replace the cover.
2).
Open the gate valves in the suction and return lines and start the
pump. If the pump fails to produce a full flow of water within four or five
minutes, switch off the power and repeat Step 1. If the pump still
fails to work, check for air leaks at the strainer cover, suction line connec-
tions, and valve stem glands before repeating Step 1.
3).
After about ten minutes of operation check the pool return fittings for
air bubbles. A continuous flow of air indicates leaks in the suction
line. Locate and correct any leaks immediately.
CONTROLLING THE OUTPUT
Keep the gate valve in the suction line fully open during opera-
tion. Should it be necessary to control the output, use a valve in the
return line.
DRAINING
There are two drain plugs on the pump case. Note that the valves in the
suction and return lines must be open to allow complete draining of
the pump, but that other provisions may be necessary for draining
the filter, heater, and pipe lines.
MAINTENANCE
The pump can be serviced without breaking the pipe connections.
Close the gate valves,
SWITCH THE ON/OFF SWITCH TO OFF AND PULL
THE PLUG FROM THE RECEPTACLE
before starting work on the pump.
Switch off the power. Close the valves in the suction and return
lines. Remove the Strainer Nut and clear cover and lift out the strainer
basket. Clean and replace the basket. Take care to clean o-ring and make
sure that it is well seated underneath clear cover and place cover back on
strainer body. Align and insert Strainer Nut, hand-tightened only (fig.2).
Re-open valves. Put pump back into operation.
NOTE: Do not re-tighten Strainer Nut while pump is in operation.
