4.0 Maintenance
Power Soak machines require minimal preventive maintenance. To ensure that the Power
Soak PS-275 remains reliable, the following tasks should be completed at the intervals
shown in this section.
4.1 Daily
4.1a Clean the liquid level sensors - The liquid level sensors are located on the side
walls of the wash and sanitizer tanks (see section 7.4). They are white plastic discs with
metal centers. The faces of the sensors need to be cleaned with a washcloth and soapy
water. Regular cleaning will prevent a build-up of difficult to remove chemicals and debris.
4.2 Monthly
4.2a Clean the motor fan shroud - The motor fan shroud is the "vented" cover located
at the end of the motor closest to the control panel. Shut off the electrical supply at the
electrical circuit breaker located in the wall mounted enclosure. Clean the pump motor
fan shroud with a stiff bristle brush and a vacuum. If a brush and vacuum are unavailable,
clean the shroud with a damp, soapy cloth. This will prevent grease and dust from
accumulating in the openings of the cover and obstructing the airflow that cools the motor.
4.2b Clean the Heating Element - Shut off the electrical supply at the system’s
electrical circuit breaker located in the wall mounted enclosure. Remove the cover plate
located in the slanted surface of the back wall of the wash tank. Remove debris that has
collected in and around the heating element. Install the cover plate when cleaning is
completed. The cover plate must be installed after cleaning to prevent foreign objects
from entering the pump suction and causing damage to the pump.
4.3 Quarterly or as needed
4.3a De-lime the wash sink - Select a de-liming agent that is safe for plastics and
stainless steel sinks. Follow the instructions on the package for mixing and fill the tank
with water. Turn on the pump motor to circulate the mixture in the tank and pump
manifolds.
The liquid level sensors must be cleaned regularly in order for the
machine to operate correctly. Dirty sensors can allow the pump motor
to operate without water in the wash tank, which will cause serious
damage to the unit.
Failure to shut off the electrical supply will result in personal injury,
including serious injury or death, and extensive equipment damage.
