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 installation 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.
1. Do not work alone.
2. 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.
3. Wear safety helmet, goggles and protective shoes, or appropriate safety materials required.
4. 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.
5. Do not stand under suspended loads!
6. 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.
7. 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.
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! The power cable ends must be protected from immersion in water as well as moisture intrusion. The cable will wick if it is not protected properly. Power cable leads shall be covered with shrink tubing.
Short-term storage is defined as any time less than six months. We recommend for this time intended to store the pump in its 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 air dry enamel paint. 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.

ELECTRICAL INSTALLATION:
GENERAL GUIDELINES
All electrical work shall be carried out under the supervision 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 complied with.
VERIFICATION OF POWER SUPPLY
Prior to making any electrical connections or applying power 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 plus or minus 10% of the nameplate value, frequency shall be plus or minus 5% of the nameplate value, the voltage phase balance shall be plus or minus 1% and the maximum corrected power factor shall be 1.0.
POWER LEAD WIRING
The ends of the cable leads are marked. Please refer to wiring diagram in the appendix for 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.
THERMAL SWITCH WIRING:
Pumps are equipped with thermal switches embedded in the stator windings. They are normally closed, designed to open under a high temperature condition and close when the temperature drops below the set point. THEY
MUST BE WIRED TO A CURRENT REGULATED CONTROL CIRCUIT.
Identify leads marked T1 and T3 and connect these wires to the thermal overload relay located in the control panel. Thermal switch leads must
be connected to validate warranty.
SEAL PROBE WIRING (OPTIONAL)
The probe utilized in the pump is a conductive sensor and is normally open. Only one lead is required to be connected to the seal fail relay located in the control panel. Probe is grounded to pump.
CAPACITORS AND RELAYS:
All single phase motors require start and/or run capacitors to operate. Refer to the wiring schematics in the appendix. Capacitors and relays must be sized for the specific motor. Please refer to nameplate for verification of capacitor sizing.
