MAINTENANCE OF THE WATER FILTER
The BLANKETROL III circulating system includes a water filter designed to clear the line of any
particulate matter as the water is pumped through the system. The water filter assembly is a plastic
T-shaped fitting that intersects the hose from the water flow indicator to the flow switch. A stainless
steel wire-mesh screen is located inside the clear plastic cap of the water filter assembly.
Quarterly, or more often if deemed necessary, the water filter should be disassembled and cleaned.
To do so, the reservoir must first be drained and the front storage drawer extended. The cap of the
water filter assembly is unscrewed. The wire mesh and the plastic cap are cleaned. The parts are
then reassembled.
CAUTION
Use distilled water only. Do Not Use De-Ionized water. De-Ionized water
may
cause corrosion to plumbing system components.
Do Not Use Tap Water.
Minerals and deposits
can clog plumbing system components.
Do not
use alcohol. Alcohol may cause blanket deterioration.
Do not
overfill. Overfilling may result in overflow when the water in the blanket
drains back into the system when the system is turned off.
CAUTION
Always drain the BLANKETROL III to a sanitary drain because
bio-contaminants
may be present in the unit’s water supply.
