Preventive Maintenance
Once the unit is in service, we suggest following the
maintenance procedures as closely as possible. The
importance of a properly established preventive
maintenance program cannot be overemphasized.
Taking the time to follow these simple procedures
will result in substantially reduced downtime,
reduced repair costs, and an extended useful lifetime
for the unit. The following is a list of suggested
periodic maintenance.
Once a Week
1.
Check to make sure that the To Process
temperature is reasonably close to the Set Point
temperature. If the temperature stays more than
2°F away from the set point, there may be a
problem with the unit. If this is the case, refer to
the Troubleshooting section of this manual or
contact our Customer Service Department.
2.
Check the pump discharge pressure. Investigate
further if the pressure starts to stray away from
the normal operating pressure.
3.
Check the pump for leaks in the seal area.
Replace pump seal if necessary.
Once a Month
Repeat items 1 through 3 listed above and continue
with the following.
4.
With the main power shut off, check the
condition of electrical connections at all
contactors, starters, and controls. Check for
loose or frayed wires.
5.
Check the incoming voltage to make sure it is
within 10% of the design voltage for the
temperature control unit.
6.
Check the amp draws to each leg of the pump
motor and heater to confirm that they are
drawing the proper current.
