SECTION 8: SERVICING INSTRUCTIONS

WARNING

Severe Injury Hazard

Install pump scroll and inlet assembly before operating high speed rotating impeller.

Keep hands, fingers and clothing away from inlet and outlet.

Install and operate equipment according to installation manual.

Failure to follow these instructions can result in death or severe injury.

WARNING

Electrical Shock Hazard

Disconnect electrical power and gas supply before servicing.

This appliance must be connected

to a properly grounded electrical source.

Failure to follow these instructions can result in death or electrical shock.

Disassembly and removal or replacement of any pump components must be done by a service con- tractor or electrician qualified in the installation and service of gas-fired heating equipment.

Overtorquing can result in a failure of components.

Failure to follow these instructions can compromise pump operation and void warranty.

8.1Pre-Season Maintenance and Annual Inspection

To ensure your safety and years of trouble-free oper- ation of the pump, service and annual inspections must be done by a contractor qualified in the installa- tion and service of gas-fired heating equipment. Disconnect electric and gas supplies before perform- ing service or maintenance.

Before every heating season, a contractor qualified in the installation and service of gas-fired heating equipment must perform a thorough safety inspec- tion of the pump.

For safety and best performance, the electrical, vent- ing, suspensions and overall pump condition are some of the areas requiring inspection.

Please see Page 17, Section 8.3 for suggested items to inspect.

8.2To Change the Motor and/or the Impeller

1.To remove the motor or impeller, the scroll must be opened. Remove the (8) nuts/bolts and insert a knife blade between the scroll halves to cut through the factory applied sealant. Separate the two halves.

2.The impeller can be removed by loosening the

(2) 3/8-24 set screws, removing the 10-32 screw and retainer assembly. With an appropriate wheel puller, remove the impeller.

3.The motor can now be removed, if necessary, by loosening the attachment hardware.

4.Re-assembly of motor/impeller combination require proper alignment. Make sure the impel- ler has a 1/4" (6 mm) clearance off the inside wall of the scroll. Verify proper motor alignment and free rotation.

5.The (2) impeller set screws should be removed and reinstalled with a drop of thread locking sealant and remain unseated during initial re- assembly.

6.Slide the impeller onto the motor shaft end. Apply a drop of thread locking sealant to the threads of the retainer screw/washer assembly. Insert the retainer screw into the shaft so that it bottoms on the end of the shaft and hub of the impeller. Torque to 30 in/lb.

7.Seat the (2) impeller set screws. Torque to 100 in/lbs.

8.Re-attach the scroll halves. Apply a bead of high temperature silicone sealant (600°F) to the scroll halves. Secure with all (7) nuts/bolts. Torque to 150 in/lb.
