gallons (5.7 liters) of distilled water with approximately 340 cc of propylene
glycol into the reservoir (DO NOT USE ALCOHOL, TAP WATER, OR DE-IONIZED

Maintenance of the Water Filter
The NORM-O-TEMP
®
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 reservoir. 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 three sided enclosure
panel removed. 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.
Do not
use alcohol. Alcohol may cause blanket/pad deterioration.
Do not
overfill. Overfilling may result in overflow when the water in the blanket/pad
drains back into the system when the system is turned off.
CAUTION
Always drain the NORM-O-TEMP
®
to a sanitary drain because bacteria may be present
in the unit’s water supply.
