General Maintenance Procedures
 Lubrication
Diff erent motor manufacturers recommend various intervals for lubrication
schedules. Load variations will dictate the frequency and amount of lubrication
required.
 When developing your lubrication schedule, consider the thermal fl uid
pump and all system pumps.
 If you have a thermal fl uid circulating pump with a packed seal, the
condition of the pump packing should be checked regularly. If fl uid
leakage increases, tighten the packing ¼ turn daily.
