Installation (Continued)
5. A pressure gauge installed in the
inlet pipe close to the inlet port,
(See Figure 6) will show if enough
water is being supplied to the pump.
See Operation Section - Priming,
Pressure Boost Installations.
6. On installations that are using
nozzles for mist spraying, install a
filter in the discharge plumbing to
prevent the nozzles from becoming
plugged. Multiple filters should be
plumbed in parallel.
Install a pressure
relief valve on any
installation where pump pressure can
exceed the pressure tank’s maximum
working pressure or on systems where the
discharge line can be shut off or
obstructed. Extreme over pressure can
result in personal injury or property
damage.
This unit is not
waterproof and is
not intended to be used in showers,
saunas or other potentially wet locations.
The motor is designed to be used in a
clean dry location with access to an
adequate supply of cooling air. Ambient
temperature around the motor should not
exceed 104ºF (40ºC). For outdoor
installations, motor must be protected by a
cover that does not block airflow to and
around the motor. This unit is not
weatherproof nor is it able to be
submersed in water or any other liquid.
To avoid dangerous or fatal electrical
shock, turn off power to motor before
working on electrical connections.
Supply voltage must be within ± 10%
of nameplate voltage. Incorrect
voltage can cause fire or seriously damage
motor and voids warranty. If in doubt,
consult a licensed electrician.
Use wire size specified in wiring
Chart F. If possible, connect pump to
a separate branch circuit with no other
appliances on it. If motor wiring diagram
differs from diagram shown below, follow
diagram on motor.

IMPORTANT:
A contained air pressure tank and pressure switch is required to keep
the pump from rapid cycling and prevent the motor from over heating. Install the tank
and switch on the house side of system.
Pump used to boost water pressure in mist spray applications (automatic operation).
NOTE:
Install solenoid valve on discharge side of pump.
Pump used to boost incoming city pressure (automatic operation).
IMPORTANT:
Clean all filters and strainers on a regular schedule.
