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
all
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.
