4.0 Maintenance
Power Soak machines require minimal preventive maintenance. To ensure that the
Power Soak PS-225 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
4.3a De-lime the wash sink - Select a de-liming agent that is safe for stainless steel
sinks and 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 will 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.
