1-3.2. External Features and Descriptions – Left Side View
The external features in Figure 2 of the NORM-O-TEMP
® unit are described as follows:
A. The water flow indicator is a paddle wheel immersed in the path of the circulating water
with a window to the outside. As water is circulated through the system, it must pass
over the paddle wheel causing it to spin (like a pinwheel) when water returns to the
NORM-O-TEMP
®
. The water flow indicator provides a visual display of the general rate
at which the water is circulating. For example, if the unit is circulating water but the
connecting hose is pinched, the circulation of the water is restricted. The change in
water flow decreases the speed of the paddle wheel.
The water flow indicator only spins when a blanket/pad or by-pass hose is connected to
the unit. It will not spin when water is circulated internally to pre-condition the water. A
total obstruction of the water path will cause the paddle wheel to stop completely.
B. Two screws on the left and right side of the unit secures the top to the base.
C. Two female Hansen fittings, quick-disconnect return couplings, on the top row are
designed for water to flow in when the male coupling of the connecting hose is attached.
D. Two male Hansen fittings, quick-disconnect outlet couplings, on the bottom row are
designed for water to flow out when the female coupling of the connecting hose is
attached.
E. The recessed handle, one on each side, is provided to assist in lifting the unit on and off
the stand or when carrying the unit.
