OPERATION/INSTALLATION INSTRUCTIONS
PLEASE READ THIS MANUAL BEFORE INSTALLING THE PUMP.
SERIES MAXI FILTER PUMPS FOR
ABOVE GROUND POOLS
1
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 because 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 equipment. These valves are
essential if the equipment is installed below deck 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 airtight.
ELECTRICAL CONNECTIONS.
Check that the information on
the name plate of the electric motor corresponds to the power
supply. Employ a competent electrician to make the wiring
installation in accordance with the local electrical code. MAXI
pumps are complete with a 25ft grounded power cord, and must
be connected only to a grounding type receptacle protected by
a ground fault circuit interrupter.
DO NOT USE AN EXTENSION CORD!
MOTOR DETAILS
WARNING. NEVER RUN THE PUMP WITHOUT WATER IN
THE PUMP CASE BECAUSE LACK OF WATER CAN
DAMAGE THE SHAFT SEAL.
OPERATION
STARTING UP.
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
IMPORTANT
This product has been carefully inspected and packed at our
factory. As the carrier has assumed full responsibility for its safe
arrival, any claim for damage to the shipment, either visible or
concealed, must be made on the carrier.
GENERAL
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. Its self-priming ability exceeds the requirements
of Standard No. 17 of the National Sanitation Foundation.
Nevertheless, 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 mouldings.
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 diffuser built into the pump case. 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-carbon
rotating face working against a ceramic seat, requires no
attention until leakage at the shaft shows that replacement is
necessary.
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 small bolts allows the motor, motor adapter, seal,
and impeller to be withdrawn as a unit, leaving the pump case
and its base in place with the piping undisturbed.
INSTALLATION
LOCATION.
Locate the pump as close to the pool as possible,
preferably in a dry, shaded, and well-ventilated area. Should it
be impossible to put the pump at or below deck 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 associated
equipment. Bear the following in mind.
1. Drainage of the filter room or pit.
2. Ventilation of the motor.
3. Access for servicing and winterizing the equipment.
4. Protection of the equipment.
PIPING.
The pump has female sockets to receive 1-1/2" NPT
(38mm) threaded fittings. Never use fittings or pipe smaller than
1-1/2" (38mm).
