The IBEX pump unit is equipped with an hour meter and an automatic
reminder to change pump oil; Red light, slow flash (does not affect
operation). See page 10 for instructions to reset light indicator.
Initially the Crankcase Oil must be changed after the first 50 operating
hours.
After that it should be changed after every 500 hours of operation.
Examples of 500 hours operation:
15 weeks of 5 hour operation per day
9 weeks of 8 hour operation per day
6 weeks of 12 hour operation per day
3 weeks of 24 hour operation per day

ELECTRICAL MOTOR SERVICE
Two types of electrical motors are used on the MicroCool

pump modules. Some small motors have sealed
rotor bearings and some require lubrication periodically. Refer to the motor nameplate for the type of motor. If
the motor is equipped with external grease nipples refer to the chart below for lubrication instructions.
Service Condition
Time Intervals
Standard
Every 3 Years
Severe
Every 1 Year
Seasonal
Lubricate at beginning of season
Electrical motors on the pump modules are pre-greased with a polyurea mineral oil NGLI grade 2-type grease
unless stated otherwise on the motor nameplate. Some compatible brands of polyurea mineral base type grease
are: Chevron SRI #2, Rykon Premium #2, Shell Oil Doilum R or Texaco Polystar RB. Motors are properly
lubricated at the time of manufacture and do not need to be lubricated at the time of installation.
NOTE: Over greasing bearings can cause premature bearing and/or motor failure. The amount of grease added
to the motor should be carefully controlled. One crank of the grease gun handle is usually sufficient.
