Installation, Operation & Maintenance Manual
GENERAL INSTRUCTIONS:
This manual is intended to provide basic
installation and start-up guidance. It is to be read
and thoroughly studied prior to attempting to
install or operate any of the equipment supplied.
Equipment damage, which occurs by not
following these instructions will void the
warranty.
SAFETY PRECAUTIONS:
Only trained qualified personnel shall be utilized
for installation and start-up.
The following is a general list of safety
precautions that should be followed when
installing, starting-up or servicing the pump
. The
pump station owner or operator is ultimately
responsible for ensuring that all equipment
is installed, started up and operated in a safe
manner.
Do not work alone.
Double check to make sure that all lifting
equipment is in good working order and that
it has adequate lifting capacity for the weight
that it will handle.
Wear safety helmet, goggles and protective
shoes, or appropriate safety materials
required.
Before working on the pump make sure that
the power is disconnected and cannot be
energized by others. Lockout and tag the
control panel circuit breaker.
Do not stand under suspended loads!
Never enter or work within a wet well without
first checking to make sure sufficient oxygen
is present and that there are no explosive or
poisonous gases present.
All personnel, who work with sewage
pumping equipment and systems shall be
vaccinated against diseases that can occur,
If there are any questions or doubts in this
area it is strongly suggested that the local
health agency be contacted.
For Hazardous Area Classifications, only use
pumps with suitable Explosion Proof Rating.
EQUIPMENT INVENTORY AND
INSPECTION:
Upon arrival of pump shipment carefully unpack
all components and compare with shipping and
purchase order documents to ensure that the
order is complete. Also inspect equipment for
any damage that might have occurred in
shipment.
If any problems are detected contact
an authorized Homa Pump Technology
Representative immediately.
TRANSPORTATION AND STORAGE
PROCEDURE:
Always lift the pump by its lifting bail or eye.
Never lift the pump by its power cable!
Pumps should be stored in an upright position,
taking extreme care to protect the power cable
and control cables from crushing, nicks or tears
which would permit water intrusion.
Power cable ends must be protected from
immersion in water as well as moisture intrusion.
The cable will wick water into the pump if it is not
protected properly. Power cable leads should be
covered with shrink tubing or suitable sealing
material.
Short Term Storage
: Short term storage is
defined as any time less than six months. We
recommend that pump and accessories be
stored in their original shipping container in a
dry, temperature controlled area. If climate
controlled storage is not possible, all exposed
parts should be inspected before storage and all
surfaces that have the paint scratched, damaged
or worn should be re-coated with an air dry
enamel paint.
Long Term Storage
: Any storage time
exceeding six months is considered long term. In
addition to the safeguards specified above, the
impeller should be rotated once a month to
prevent the mechanical seals from being
damaged, and the pump should be inspected.
The oil in the mechanical seal chamber should
be drained and replaced prior to commissioning.
