Minimum capillary tube bending diameter is 1/2” I.D. (see Figure 4). Figure 3 (Sensing Bulb) 1” Do Not Bend or Kink Crimped End 1/2” Rod Figure 4 (Capillary Tube) C. Any deformations of bulb or capillary that result in leakage of fluid from control renders control inoperative. D. Avoid passing control capillary tube through zones whose temperature is in excess of controlled process temperature. Erratic control or destruction of control function may result.

Do not mount adjacent to space around wires in the conduit with rock wool. a large magnetic contactor, as vibration and shock will cause thermostat to interact erratically – resulting in chattering of the contactor. WARNING: Do not twist or uncoil the coiled element on top of the case. The proper location of a heavy duty room thermostat is important to assure good performance. 1. Locate where air circulates freely. 2. Never install on or near outside wall. 3. Keep away from windows or doors. 4.

never above 150°F. 1. Thermostat must be mounted in a vertical position only. 2. Use sheet metal or wood screws through the four 7/32” diameter mounting holes in baseplate to mount control (see Figure 2). 3. For controlling platen or die temperatures, insert entire sensing bulb into drilled holes selected for snug slip fit. The longer, more sensitive Style 9 bulbs should be used for controlling air temperatures or pipe line heating. 4. NOTICE: A. Bending or deforming sensing bulb will alter cont

Applications – Automatically controls room temperature by turning electric air heaters on and off. Can be used to control the air heaters directly, within thermostat rating. For higher ratings use thermostat with magnetic contactor. Place thermostat on inside wall, away from undue heating or cooling influences, about 4 feet above the floor. NOTICE: Type WCRT thermostats are designed for temperature control service only. Because they do not fail safe, they should not be used for temperature limit

CAUTION: Users should install adequate back-up controls and safety devices with their electric heating equipment. Where the consequences of failure may be severe, back-up controls are essential. Although the safety of the installation is the responsibility of the user, Chromalox will be glad to make equipment recommendations. Principle of Operation – Control action of these thermostats is provided through the principle of liquid volume change. With a variation in temperature, the liquid in the s
