5.1 PREVENTIVE MAINTENANCE

A.

The following is a general guide to preventive maintenance. The frequency of

maintenance will vary with each application, installation conditions, flow rates, hours of

use and operating temperatures.

B.

Preventive maintenance:

1.

Tighten all wiring connections.

2.

Check plumbing. Repair any leaks. The factory recommends using a high

temperature graphite paste and teflon tape on all plumbing connections.

3.

Descale water cooling channels in the pump seal cooling adapter.

4.

Descale water cooling channels in the heat exchanger (if installed).

5.

Check process fluid for degradation. The operating conditions affects the usable

life of the process fluid. Most heat transfer fluid manufacturers have an analysis

program where a sample of process fluid can be sent to the manufacturer to

determine when the fluid should be replaced. Some manufacturers even have

reclamation programs of the spent fluid.

6.

Check sight glass for proper operation. Due to oil degradation, the sight glass

feeder tubes may become clogged. In such cases, the sight glass may show

an inaccurate level. Follow proper shut down procedures before removing sight

glass to check feeder tubes.

7.

Tighten heater contactor terminals.
