4-3. MAINTENANCE OF THE WATER FILTER
The BLANKETROL II 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.
After draining the reservoir as described in Section (4-2.4.):
A. Disconnect the unit from its power source.
B. Extend the front storage drawer as described in Section (5-1.5).
C. Locate the T-shaped water filter assembly tucked under the reservoir,
D. Firmly grasp the notched rim of the cap of the assembly and turn it counterclockwise.
The cap may contain a small amount of water.
E. Remove the wire mesh.
