Tank Heating
15.1 Usage
In places where the FROTHPAK™ Refill System is used where the
ambient temperature is below 65°F (18°C), an external source to heat
the chemical in the tanks may be required.
Heating bands are available for both the 17 gallon and the 60 gallon
tanks, through:
McMaster-Carr

The heater band McMaster model numbers are as follows:
17 gallon: 3545K42

The model number for the control box is PL312.
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 temperatures 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
Electro-Flex Heat, Inc.

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 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.
