Maintenance
Cleaning filters
Filters should be cleaned a minimum of once a week
depending on the cooking equipment, cooking
frequency, food type and quantity. When servicing or
cleaning the filters, turn the pump power off (green
button on control cabinet should not be lit). Close the
ball valve in the cabinet that supplies the water to the
filters. Then press the ‘Pressure Release’ button on the
control cabinet for about 5-10 seconds.
NOTE
Do not completely close the “Throttle Valve” when the
system is operational.
WARNING
Make sure the “Pressure Release” button is pressed
before disconnecting anything. If system is not purged
properly, water spillage can occur, which can cause
hot water burns.
