10. Additional for FM submersible pumps

10.1. 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 equip-
ment supplied. Equipment damage, which occurs by not
following these instructions will void the warranty.
10.2. SAFETY PRECAUTIONS
Only trained qualified personnel shall be utilized for instal-
lation and start-up.
The following is a general list of safety precautions that
should be followed when installation starting-up or servic-
ing the pump.
The pump station owner or operator is ultimately re-
sponsible 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 lift-
ing 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 pow-
er is disconnected and cannot be energized by oth-
ers. 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.
10.3. EQUIPMENT INVENTORY AND INSPECTION
Upon arrival of pump shipment carefully unpack all com-
ponents and compare with shipping and purchase order
documents to ensure that the order is complete. Also
inspect equipment for any damage that might have oc-
curred in shipment. If any problems are detected contact
an authorized HOMA customer service immediately.
10.4. TRANSPORTATION AND STORAGE PROCEDURE
Always lift the pump by its lifting bail or eye bolt.
Never lift the pump by its power cable! Jacketed
pump should never stored or shipped with the pump
by the jacket. Damage to Sealing O ring may result.
Pumps should be stored in an upright position, taking ex-
treme 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 im-
mersion in water as well as moisture intrusion.

The cable will wick water into the pump if it is not protect-
ed properly. Power cable leads should be covered with
shrink tubing or suitable sealing material during storage.
Short Term Storage: Short term storage is defined as any
time less than six months. We recommend that pump and
accessories be stored in its original shipping container in a
dry, temperature controlled area. If climate controlled stor-
age is not possible, all exposed parts should be inspect-
ed before storage and all surfaces that have the paint
scratched, damaged or worn should be re-coated with air
dry enamel paint. The pump should be stored in an upright
position.
Long Term Storage: Any storage time exceeding six
months is considered long term. In addition to the safe-
guards specified above, the impeller should be rotated
once a month to prevent the mechanical seals from be-
ing damaged, and the pump should be inspected. The
seal chamber oil should be drained and replaced prior to
commissioning. The pump should be stored in an upright
position.
10.5. ELECTRICAL INSTALLATION
10.5.1. GENERAL GUIDELINES
All electrical work shall be carried out under the supervi-
sion of an authorized, licensed electrician. The present
state adopted edition of the National Electrical Code
as well as all local codes and regulations shall be com-
plied with.
10.5.2. VERIFICATION OF POWER SUPPLY
Prior to making any electrical connections or applying pow-
er to the pump, compare the power supply available at the
pump station to the data on the unit's nameplate. Confirm
that both voltage and phase match between pump and
control panel. The voltage supplied at the pump shall be
+5 / -10% of the nameplate value, frequency shall be +
/ - 1% of the nameplate value, the voltage phase balance
shall be within 1% and the maximum corrected power
factor shall be 1.0.
10.5.3. POWER LEAD WIRING
HOMA pumps may be provided with 1 or more cables,
depending on motor horsepower and operating voltage.
Power leads L1, L2, & L3 may be provided as single con-
ductor, or as multiple conductors. Multiple conductor
configurations may use leads from separate cables, or
may use two conductors within one cable. Please refer
to wiring diagram in the appendix for specific connection
details.
The pump must be connected electrically through a motor
starter with proper circuit breaker protection in order to
validate warranty. Do not splice cables.
10.5.4. THERMAL SWITCH WIRING
Pumps are equipped with thermal switches embedded in
the stator windings which are normally closed, automat-
ically resetting switches. Switches will open when the
internal temperature rises above the design temperature,
and will close when the temperature returns to normal.
Thermal switches must be wired to a current regulated
control circuit in accordance with the NEC.
