PUTTING THE UNIT INTO SERVICE

1. Assure that the unit is piped in accordance with instructions

in this manual.

2. Isolate tank before performing any system leak test. Do not pressurize the tank as part of the leak test. Failure to do this can result in serious injury or death.

3. Check floats and alternators for free operation.

4. Wire unit per National Electrical Code. See representative wiring diagrams.

5. Install drain plugs.

6. Fill receiver half full of water to prime pump(s) and prevent possible damage to pump seals. Avoid freezing conditions after unit receiver has been filled.

7. Check for proper rotation of all three phase motors. Rotation must be clockwise looking down on the motor as indicated by directional arrow on pump casting. If pump runs backwards, interchange two wires (3 phase only).

8. Throttle plug cock in discharge line until pressure at pump (while pump is discharging) approaches pump rated pressure. Tighten plug nut to secure adjustment.

9. Remove start-up label (below) from panel (if applicable) after complying with instructions.

10. If possible, observe operation thru several cycles.

WARNING: EXPLOSIBLE

Do not pressurize receiver. Isolate receiver during leak

test. Do not plug overflow. Do not restrict vent opening to atmosphere. Open valves slowly. Failure to follow these instructions could result in serious injury or death.

WARNING: HIGH VOLTAGE

Disconnect and lock out power before connecting or

servicing unit. Failure to follow these instructions could result in serious injury or death.

CAUTION: DO NOT RUN DRY.

SEAL DAMAGE MAY OCCUR.

Inspect pump seal regularly for leaks. Replace as required.

Failure to follow these instructions could result in injury or property damage.

CAUTION: DO NOT REVERSE

Reverse operation can cause extensive damage to

pumps. Jog the motor to test for direction of rotation. Failure to follow these instructions could result in injury or property damage.

OPERATION AND MAINTENANCE

Operators must be familiar with all sections of this manual to

understand the operation of the unit. Hot water, steam and electricity can be hazardous.

Check motor nameplate for any lubrication requirements. Pumps require no lubrication.

NOTICE / AUTO RESTART

Single phase motors will restart automatically after thermal

overload protector trips. Overload thermal relays in starters must be reset manually. A properly installed unit should function unattended for long

periods of time. Periodic checks to assure proper operations are highly recommended. Refer to trouble shooting section when necessary.

A variety of control options are available and are furnished in accordance with user specifications. Refer to wiring diagrams (when furnished) to determine control switch settings.

The inlet strainer (when furnished) is intended to protect the pump and system. Periodic cleaning should be included in the maintenance schedule. Check frequently in new systems.

WARNING: EXPLOSIBLE

Do not pressurize receiver. Isolate receiver during leak

test. Do not plug overflow. Do not restrict vent opening to atmosphere. Open valves slowly. Failure to follow these instructions could result in serious injury or death.

WARNING: HIGH VOLTAGE

Disconnect and lock out power before connecting or

servicing unit. Failure to follow these instructions could result in serious injury or death.

CAUTION: SUBSEQUENT DAMAGE

A unit showing symptoms of possible problems

(overflow, noise, leaks, vibrations, continual operation, etc.) must be corrected immediately. Failure to follow these instructions may result in full liability for subsequent injury or property damage.
