FIRE/EXPLOSION HAZARD. This thermostat is not

intended for use in hazardous atmospheres where

flammable vapors, gases, liquids or other com-

bustible atmospheres are present as defined in

the National Electrical Code. Failure to comply can

result in personal injury or property damage.

NOTICE: Type GNIT Thermostats are designed for temperature

control service only. Because they are not fail safe, they should

not be used for temperature limiting duty.

The system designer is responsible for the safety

of this equipment and should install adequate

back-up controls and safety devices with their

electric heating equipment. Where the conse-

quences of failure could result in personal injury or

property damage, back-up controls are essential.

The GNIT Non-Indicating Corrosive Resistant Thermostat is

designed for applications in atmospheres where corrosive material is

present. The double pole/single throw thermostat is available with

either a 5 foot or 12 foot copper capillary which is sleeved with

Note: Do not mount thermostat where it will be subject to vibra-

tion or shock. Do not mount adjacent to a large magnetic contac-

tor, as vibration and shock will cause thermostat to interact errati-

cally — resulting in chattering of the contactor.

The air temperature in and around the thermostat enclosure

should be kept as near to normal room temperature as possible...

Application Notes

1. Customer external fuse required.

Process Temperature Differential — is variation in controlled

process temperature between maximum, when thermostat turns

OFF and minimum, when thermostat turns ON. This spread in

temperature may be minimized by:

1. Making sure control is mounted to vertical surface. (See Step 1,

MOUNTING.)

2. Avoid excess heating capacity (oversized heaters).

3. Locating control sensing bulb in optimum position between

heat source and work.

MOUNTING

never above 150˚F or below 30˚F.

1. Thermostat must be mounted in a vertical position only.

2. Use sheet metal or wood screws through the four 1/4" diame-

ter mounting holes in baseplate to mount control.
