LIST OF WARNINGS
1. Make sure the power source is capable of handling the electrical
requirements of the grinder pump, as indicated on the nameplate.
2. A disconnect switch should be installed in the circuit bringing electrical
power to the pump.
3. The progressing cavity grinder pumps are operated by variable level oat
control switches. It is the responsibility of the installing party to see that oat
control switches will not hang up on the grinder pump or other pit peculiarities
and are secured so that the grinder pump will shut off. It is recommended to
use rigid pipe and ttings and the pit be at least 61 cm (24") in diameter for
simplex systems and 91.4 cm (36") or larger in diameter for duplex systems.
4. Grinder installations should be checked yearly for debris and/or build up
which may interfere with the “ON” or “OFF” positions of variable level oat
control switches. Repair and service, other than cutter assembly maintenance,
should be performed by a Zoeller Authorized Service & Warranty Center or
Customer Care Center.
5. Maximum operating temperature must not exceed 54 °C (130 °F).
6. Do not operate an unsubmerged progressing cavity pump. Dry pump
operation may damage the hydraulic stator due to lack of lubrication. Do
not run dry.
7. To ensure proper pump operation, a swing or apper style check valve
must be installed in the pump discharge line. A faulty or non-functional
check valve when combined with a pressure sewer may prevent the
pump from starting.
1. Make sure pump connection contains a ground terminal. The power cord
on all Zoeller Progressing Cavity Grinder Pumps contains a green conductor
for grounding to help protect you against the possibility of electric shock.
2. Make certain the electrical service is within reach of the power supply
cord.
3. Make sure any panels and branch circuits are equipped with proper size
fuses and circuit breakers. An independent power circuit is recommended,
sized according to the National Electrical Code, for the current shown on
the grinder pump nameplate.
4. For your protection, always disconnect the power source to the grinder
pump before handling. All grinder pumps must be properly grounded and
wired in accordance with the “National Electrical Codes” and all local codes
and ordinances.
5. Installation of electrical hardware and checking of control panels
and circuits should be performed by a qualied licensed electrician.
6. Risk of electrical shock - These pumps have not been investigated for use
in swimming pool areas.
7. According to the state of California (Prop 65), this product contains chemicals
known to the state of California to cause cancer and birth defects or other
reproductive harm.
NOTE: Pumps with the UL mark and the US mark are tested to UL standard UL778.
CSA-certied pumps are certied to CSA standard C22.2 No. 108.
CAUTION
SEE BELOW FOR
LIST OF CAUTIONS
Do not attempt to turn the cutter blades
located on bottom of the unit with ngers. Use a wrench
when checking or removing the cutter.
Progressing cavity grinder pumps are designed for
pressure sewer applications. A UL listed and CSA certified pressure relief
valve must be installed in the system to prevent excessive pressure buildup.
