CAUTION
!
6.2 Pump Mounting
The HH pump requires a Flooded Suction installation. The pump
should be securely mounted at the base of the storage tank with the
suction piping sloping downward to the pump.
All piping should be cleaned and blown-out
prior to connection to the HH pump.
6.3 Plumbing
Always adhere to local plumbing codes and
requirements. Be sure the installation does not
constitute a cross connection. Check your local
plumbing codes for guidelines. LMI is not
responsible for improper installations.
The HH high pressure metering pump utilizes 1/4" N.P.T.
connections. These connections require the use of Teflon Tape.
When applying the Teflon Tape, make sure it does not extend over
the fitting. This would restrict the flow of chemical.
All piping being attached to the HH must be cleaned and blown out
to prevent debris from entering the Liquid End. A 100 micron
strainer or filter should be installed to prevent any debris in the
chemical from entering the pump.
Both the discharge and suction check valves
should be supported while tightening the mating
pipe connections. This is done by placing a
wrench on the check valve flat, to prevent it
from turning and becoming over tightened,
when connecting the pipe.
