3.NOTICE:

A.Do not bend or deform sensing bulb. This will alter control calibration.

B.Do not kink capillary tube. The resulting constrictions in fluid flow can destroy control function or broaden tempera- ture differential. Minimum capillary tube bending diameter is 1/2” I.D.

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 which have temperatures in excess of controlled process tempera- ture. Erratic control or destruction of control function may result.

WIRING

ELECTRIC SHOCK HAZARD. Disconnect all power before installing or servicing thermostat. Failure to do so could result in personal injury or property damage. Thermostat must be installed by a quali- fied person in accordance with the National Electrical Code, NFPA 70.

ELECTRIC SHOCK HAZARD. Any installation involving thermostats must be performed by a qualified person and must be effectively grounded

in accordance with the National Electrical Code to eliminate shock hazard.

1.Electric wiring to thermostat must be installed in accordance with the National Electrical Code and with local codes by a quali- fied person. CAUTION: Use copper conductors only.

2.Entrance for wiring is provided by two 1/2” conduit holes on each side of the unit.

3.Remove four face mounting screws and pull off front cover.

4.Connect wires according to wiring diagrams (Figures 2 & 3).

5.Replace cover and tighten screws.

6.Note: If load amperage or voltage rating exceeds switch rat- ing, a contactor must be used. Contactor and wiring to be sup- plied by customer.
