The installation, operation, and care of your Hydroglass ®Pump is
very similar to cast iron pumps. We ask, however, that you keep
the following points in mind.
NOTICE: Use Teflon tape supplied with the pump for making aU
threaded connections to the pump.
DO NOT USE PIPE JOINT COMPOUND.
1. Wrap 1-1/2 to 2 turns of Teflon tape to all male pipe threads
being attached to the pump. This will insure leakproof connec-
tions. Do not overtighten threaded fittings in the plastic pump.
If leaks do occur, remove the fitting, replace the Teflon tape,
and rewrap with 1-1/2 to 2 turns of Teflon tape and remake the
connection.
2. Independently suppo_ all piping connected to the Hydroglass ®
Pump.
OPERATION
Priming the Pump
l_k CAUTION_ NEVER run pump dry. Running pump without
water may overheat unit, damaging seals and possibly burning per-
sons handling pump.
m
LA WARNING_ NEVER run pump against closed discharge. To
do so can boil water inside pump, causing hazardous pressure in
unit and possibly scalding persons handling pump.
1. Remove priming plug. Fill pump with water. Replace priming
plug. If a priming tee and plug have been instailed for a long hor-
izontal run, be sure this line is filled and the plug replaced.
(Figure 2, Page 4).
2. Start the pump. Water will be pumped in a few minutes; the
time depending upon the depth to water and length of hori-
zontal run. If pump does not prime, check for a possible leak in
the suction line. Reprime. Check to be sure snction lift - dis-
tance from pumping water level to pump - does not exceed 20
feet. See "Piping in the Well" on Page 4.
