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 pumps using auxiliary variable level 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" (0.9 m) 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" (5 mm)) 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 counterclockwise
looking into impeller inlet. See page 5 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 local guidelines on
confined space requirements.
1. Inspect your pump.
Occasionally, products are damaged during shipment. If the unit is damaged, contact your dealer before using.
DO NOT
remove the test plugs in
the cover nor 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.
1.
Do not lift, carry, or hang pump by the electrical cables. Damage to the electrical cables
can cause shock, burns or death.
2. 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.
3.
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.
4. 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 governing electrical code for the current shown on the pump nameplate.
5.
Risk of electric shock - These pumps have not been investigated for use in swimming
pool areas.
6.
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.
7.
The appliance is not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have
been given supervision or instruction to concerning use of the appliance by a person
responsible for their safety.
