overheated or vapour locked. Should this occur, either a
check valve must be installed in the suction line or the
length of the suction pipe must be shortened.
d) DRAINING: Should the pump be subject to freezing tem-
peratures, it will be necessary to drain the pumpcompletely.
To drain, remove the drain plug located at the bottom of
the front face of the pump casing and the priming plug
and make sure that the drain hole is not choked. After
all the water has been drained, operating the pump for
a few seconds will ensure that the impeller is devoid of
water (make sure that the suction line is also devoid of
water).
WARNING - ELECTRICAL PRECAUTIONS
All wiring, electrical connections, and system grounding must
comply with the National Electrical Code (NEC) and with any local
codes and ordinances. Employ a licensed electrician.
WARNING - RISK OF ELECTRICAL SHOCK
• Have an electrician provide electrical power to the motor.
• Motor must be grounded and terminal cover in place to
reduce electrical shock hazard.
• Keep motor operating area as dry as possible.
• Always disconnect power before servicing.
• Not investigated for use in swimming pool areas.
a) LUBRICATION:
1) The pump requires no lubrication.
2) Refer to instructions provided by the motor manufacturer.
b) REPLACING MECHANICAL SEAL: (Refer to Fig. 2)
Disassembly:
1) Disconnect electric power.
2) Drain pump.
3) Disconnect piping.
4) Remove the bolts from the casing.
5) Unscrew the impeller (2) in a counter-clockwise direction.
6) Slip the rotating seal (7) off the shaft.
7) i) With square fl ange motors, remove the seal plate
from the motor end shell.
ii) With 56J frame motors, unbolt the adapter from the
motor face and remove.
8) Inspect the ceramic seat (8). If it needs replacing, press
it out of the adapter from the motor end.
Reassembly:
1) Clean all parts thoroughly before reassembly.
2) Use liquid soap on the rubber cup on the ceramic seat
and push it into the adapter, using thumbs only. Make
sure that the smooth surface of the ceramic seat faces
outwards.
3) Assemble the adapter to the electric motor or gasoline
engine, being very careful so as not to damage the
ceramic seat.
4) Use liquid soap on the rotating seal and slip it onto the
shaft with the shiny side of the ring towards the ceramic
seat. Should a sleeve be present in the model, fi rst slide
the rotating seal onto the sleeve and then slide the sleeve
(the chamfered end fi rst) onto the shaft. Make sure that
the shiny side of the ring on the rotating seal is in contact
with the ceramic seat.
5) Screw on the impeller.
6) Assemble the casing to the adapter and use a new
gasket (3) and new washers on the bolts.

PRECAUTIONS
a) No matter what the model of the pump, whenever it is
dismantled and then reassembled, always check to see
that the impeller rotates freely within the casing.
b) The electric motor models have a fl inger on the shaft. This
fl inger must not be removed.
