A Series Installation, Operation & Maintenance Manual Project: _______________________ Installation: ____________________ Pump Model: ______________ Serial Number: ___________ AIOM REV. 6/12 HOMA Pump Technology, Inc.
A Series 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.
A Series 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.
A Series Variable Frequency Drives: Special considerations must be taken when operating pumps with variable frequency drives (inverters). The inverter circuit design, horsepower required by pump, motor cooling system, power cable length, operating voltage, and anticipated turndown ratio must be fully evaluated during the design stage of the installation.
A Series Place the guide rails (supplied by others), cut to length into the rings of the base. The rails will be secured at the top of the pump station with the upper guide bar bracket and extend down to the sump floor. Install the upper guide bar bracket to maintain vertical orientation of the guide rails. For stations exceeding 10 feet in depth intermediate guide bar brackets are recommended. One bracket is recommended for each additional 10 feet of station depth.
A Series Suction Piping Suction piping should be at least as large as the pump inlet elbow suction. If reducers are utilized they should be of the eccentric, conical type and must be installed with the level side up. Suction piping should be run as straight as possible with a recommended 10 suction diameter distance before pump inlet. Rough sections in pipe suction line can cause turbulence and result in severe vibration of the pump.
A Series Installation / Startup Troubleshooting: Listing of Possible Causes: Only authorized service personnel who are trained professionals shall troubleshoot and repair pumps that are experiencing operational or performance difficulties. 1. 2. 3. 4. 5. All HOMA pumps are factory tested, yet startup difficulties can occur with any mechanical equipment. Please note that our technical support staff stands ready to assist you with any problem or difficulty you might encounter with our equipment.
A Series MAINTENANCE 5. SEAL CHAMBER OIL Regular maintenance will help ensure longer pump life and more reliable operation. It is recommended that pumps in intermittent operation be inspected twice a year and pumps in continuous operation be inspected every 1,000 hours. The following is a listing of required inspection and maintenance items. If any of the problems described in the following list exists stop operating the pump to avoid damage or personal injury. 1.

A Series PROFILE SEAL INSTALLATION When installing a profile seal, one side of the seal has a larger diameter ridge on the outside edge. This side goes to the inside of the guide claw as seen below. Press the seal into its seat starting on one side and work the rest of the seal into the same position. When finished, it should look as below. When properly installed, the profile seal will stay in place when pulled straight outwards.
A Series Single Phase Pump Start-Up Procedure Run Capacitor sizing can vary depending on the incoming supply voltage provided. HOMA Single Phase pumps are provided with Start and Run Capacitor(s) sized for 220-230V under load. Frequently, the available line voltage is considerably different than indicated, and the Run capacitor(s) may need to be resized to match the available field voltage.
