Electrical Safety

WARNING

Wire motor for correct
voltage. See “Electrical”
section of this manual
and motor nameplate.

Ground motor before
connecting to power
supply.

Meet National Elect-
rical Code and local
codes for all wiring.

Follow wiring instruc-
tions in this manual
when connecting mo-
tor to power lines.

WARNING

General Safety

Hazardous voltage.
Can shock, burn, or
cause death.

Ground pump before
connecting to power
supply.

Hazardous pressure!
Install pressure relief
valve in discharge pipe.

Release all pressure on
system before working on
any component.

Relief valve must be capable of passing full pump flow at
75 PSI.

Pump water only with this pump.

Periodically inspect pump and system components.

Wear safety glasses at all times when working on pumps.

Keep work area clean, uncluttered and properly lighted;
store properly all unused tools and equipment.

Keep visitors at a safe distance from the work areas.

Pump body may explode if used as a

booster pump unless relief valve capable of passing
full pump flow at 75 PSI (517 kPa) is installed.

Motor normally operates at high temperature

and will be too hot to touch. It is protected from heat dam-
age during operation by an automatic internal cutoff
switch. Before handling pump or motor, stop motor and
allow it to cool for 20 minutes.

Make workshops childproof; use padlocks and master
switches; remove starter keys.

General Safety

Do not allow pump, pressure tank, piping, or any other sys-
tem component containing water to freeze. Freezing may
damage system, leading to injury or flooding. Allowing
pump or system components to freeze will void warranty.
