During the initial start-up, the controls for the heater bands can
be set at 3 or 4 for two hours . However, for continuous operation,
"LO" would be the desired setting, unless extremely low tempera-
tures are experienced .
15.2 Installation Procedure – Tank Heater Band
1 . Wrap and clamp heater band around tank prior to
switching on .
2 . Pull on spring, at the same time hold end of heater against
the tank .
3 . Place a loop of the spring over the hook .
4 . The heater should not be clamped in dented areas of the tank .
5 . The heater must be in full contact with the tank and below
the level of the liquid while in operation .
6 . DO NOT bend the heater sharply as this may cause internal
damage to the heating element .
7 . DO NOT use outside insulation .
NOTE: Heaters are available for other tank heating operations, refer to

15.4 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 set-
ting . 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 opera-
tion 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 .

This control effectively regulates heating mantles, tapes and
cords . Minitrol may also be used for small furnaces or ovens,
hot plates, dies or other applications requiring infinite control .
The control should not be exposed to ambient temperatures
above 125°F (52°C) .
