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). 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 I.V. stand or when carrying the unit.
