•
Maximum Liquid Temperature: 160ºF (71ºC)
•
Maximum Starts per Hour: 20 – evenly distributed
PIPING
•
Pump MUST be installed horizontally on a solid flat
surface, with discharge on top.
•
Allow adequate space for servicing and ventilation.
Protect the unit from weather and water damage due
to rain or flooding or freezing temperatures.
•
Piping should be no smaller than the suction and dis-
charge connections and kept short as possible, avoiding
unnecessary fittings to minimize friction losses.
•
All piping MUST be independently supported and
MUST NOT place any piping loads on the pump.
NOTICE: DO NOT FORCE PIPING INTO PLACE AT
PUMP SUCTION AND DISCHARGE CON-
NECTIONS.
•
All pipe joints MUST be airtight.
The use of Teflon TM tape, or equivalent, is recom-
•
mended for ALL pipe joints.
SUCTION
•
Total suction lift, including elevation and pipe friction
loss, should not exceed 25 feet of head.
•
Install an airtight union in the suction line close to the
pump. See Figure 1.
•
Installation of a foot valve at liquid source is recom-
mended.
NOTICE: FOR INSTALLATIONS WITH LONG SUC-
TION PIPING, BOTH A FOOT VALVE
AND A CHECK VALVE ARE RECOM-
MENDED.
•
To avoid air pockets, no part of the piping should be
above the pump suction connection and piping should
slope upward from liquid source.
•
For installations with long suction piping, fill the suc-
tion pipe with water before connecting to pump.

DISCHARGE

•
Install a tee at the discharge connection of the pump.
The top opening of the tee is required for initial prim-
ing. See Figure 1.
