Glas-Col Power Control Description and Operation

The Glas-Col Minitrol is a manually adjusted power control of

percentage timer design . Minitrol is designed to proportion full output
power 5 .5% to 100% of time depending on the dial setting . The “Off ”
position positively breaks both sides of the line .

The control can be used on any non-inductive fused resistance load up

to 15 amps and 120 volts . Smaller fuses may be used for protection of
very small loads . Simply plug device into a 3-wire outlet of the control
and insert plug of Minitrol cord into a wall receptacle . The pilot light is
connected across the output side of the control and indicates power to
the load .

Minitrol’s operation and control is adjusted by the operator and does
not utilize a sensing element . after a desired temperature has been
determined on the initial run, a simple resetting of the dial offers
control for repeat operations .
