Preinstallation Information
1. Check to be sure your power source is capable of handling the voltage
requirements of the motor, as indicated on the pump nameplate.
2. The float switches must be connected to an intrinsically safe circuit in the
control panel. The installation of float switches is the responsibility of the
installing party and care should be taken that the tethered float switch will
not hang up on the pump apparatus or pit peculiarities and is secured so that
the pump will shut off. It is recommended that rigid piping and fittings be used
and the pit be 36" or larger in diameter.
3.
INFORMATION - VENT HOLE PURPOSE
.
It is necessary that all submersible pumps
capable of handling various sizes of solid waste be of the bottom intake design
to reduce clogging and seal failures. If a check valve is incorporated in the
installation, a vent hole (approx. 3/16") must be drilled in the discharge pipe
below the check valve and pit cover to purge the unit of trapped air. Water
stream will be visible from this hole during pump run periods. This vent hole
should be checked periodically for clogging and cleaned as necessary.
Trapped air is caused by agitation and/or a dry basin.
4. Water hammer creates momentary high pressure surges. These surges can
cause severe damage to check valves and the piping system. Consideration
for water hammer must be included in the piping system design. Reference
ASPE Data Book, Chapter 2.33. Some systems may require external spring
or lever weighted check valves or other engineered solutions.
5. Three phase pumps must be connected for proper rotation, which is counter-
clockwise looking into impeller inlet. See page 4 for instructions for checking
3 phase rotation.
6. Grinder installations should be checked frequently for debris and/or buildup
which may interfere with the “ON”/”OFF” cycles or the positions of variable
level float control switches. For repair and service, other than cutter assembly
maintenance, contact factory.
7. Care should be taken during the initial installation to be sure that adequate
air supply is available whenever any person is in the basin. Always follow
OSHA guidelines on confined space requirements.
1.
Inspect your pump.
Occasionally, products are damaged during shipment. If the unit is damaged, contact your distributor before using. DO NOT remove the test
plugs in the cover or the motor housing.
2.
Carefully read the literature
provided to familiarize yourself with specific details regarding installation and use. These materials should be retained for future
reference.
3. National Electrical Code (NEC) articles 500 through 503 explain in detail the requirements for the installation and wiring of electrical equipment in hazardous locations.
1.
Not for use in acidic atmospheres.
2. Do not lift, carry, or hang pump by the electrical cables. Damage to the electrical
cables can cause shock, burns or death.
3.
Make sure there is a properly grounded connection available.
All pumps are
furnished with provisions for proper grounding to help protect you against the
possibility of electrical shock.
4. Make certain that the control box is within the reach of the pump’s power supply
cord.
DO NOT USE AN EXTENSION CORD
.
Extension cords that are too long or too
light do not deliver sufficient voltage to the pump motor. But, more important, they
could present a safety hazard if the insulation were to become damaged or the
connection end were to fall into the sump.
5.
Make sure the pump electrical supply circuit is equipped with fuses and
disconnect or circuit breakers of proper capacity.
A separate branch circuit is
recommended, sized according to the “National Electrical Code” for the current
shown on the pump nameplate.
6. Risk of electric shock - These pumps have not been investigated for use in swim-
ming 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 repro-
ductive harm.
8. Electrical wiring and protection
must
be in accordance with the National Electrical
Code per NEC articles 500 through 503 for installation in Class I, Division 1, Group
C & D Class I, Zone 1, Groups IIA & IIB
locations, and any other applicable state
and local electrical requirements.
9.
Do not attempt to turn cutter rotor located on bottom of the unit with fingers.
Use the appropriately sized wrench when checking or removing the
cutter.
NOTE: cCSAus listed pumps are certified to CSA Standard C22.2 No. 145.
Tested
to FM Standards 3600 & 3615 by CSA.
