WARNING!
THE PUMP MUST BE WIRED BY A QUALIFIED
ELECTRICIAN, USING AN APPROVED STARTER
BOX AND SWITCHING DEVICE.
On 3 phase pumps only, “Motor Protection”
must be provided by the installer. All 3 phase
pumps must be installed with magnetic starters
having 3 leg overload protection in accordance
with the NEC (National Electric Code). For
duplex installations, both pump motors must
have separate overload protection.
Pumps with seal leak detectors must be
connected to the proper control circuitry.
DANGER!
HAZARDOUS MOVING PARTS. To reduce risk of
injury, disconnect power before servicing. Never
put fingers near grinder impeller or in pump inlet
when pump cord is connected or pump is
operating.

DANGER!
In the initial installation, before sewage is
admitted to the basin, there is no danger on
entering the basin. AFTER SEWAGE HAS BEEN
IN THE BASIN, THERE IS DANGER. Sewage
water produces methane and hydrogen sulfide
gasses, both of which are highly poisonous. A
breathing device may be required. Never enter
the basin unless cover is open and outside
blower is used to force fresh air into the basin.
Also the worker in the basin must wear a
harness attached to the surface so he can be
pulled out in case of asphyxiation.
NEVER WORK ALONE!
WARNING!
Do not exceed working load limit of lifting chain,
cable or rope. Do not use lifting chain, cable or
rope where failure could result in loss of life.

for damage before and after each lift. Do not use
any lifting devices that are not rated for and
designed to lift the weights involved with these
pumps. DO NOT LIFT PUMP BY POWER CORD.
Do not install or remove pump with person(s) in
the basin.
This pump is designed to handle materials
which could cause illness or disease through
direct exposure. Wear and use protective
clothing when working on the pump or piping.
