Servicing
If any component of the water treatment system is changed or re-
placed, the user should conduct appropriate tests to ensure that the
revised system meets all standards to which it was initially tested.
Always remove WaterGard from the power source and turn off the
water prior to any maintenance activities!
1. A daily/weekly System Log for the WaterGard system must be filled out
completely each time the system is used. See page 28.
2. The membranes, carbon and sediment filter are non-durable components
and will need to be exchanged periodically.
a.
The membranes will need to be cleaned or replaced when the flow
of product water decreases more than 15-20% assuming the water
temperature remains constant, and no other issue is the root cause.
b. The 5-micron sediment filter will need to be replaced whenever the
differential pressure on the outlet is 10 psi or greater than the pres-
sure on the inlet of the filter housing.
3. The accuracy of the conductivity display should be verified with a cali-
brated, hand-held meter at least annually. If the conductivity display is not
within 5% of the hand-held meter readings, the controller should be cali-
brated in accordance with the procedures in Controller Adjustments on
page 17.
System Preparation for Maintenance
