After a suitable location has been chosen for the control, remove the front cover by using a 3/16" Allen head wrench in the 6 cover screws.

Fasten control to mounting surface.

Use 1/2" pipe for connection to electrical outlet.

The switch mechanism of remote bulb types may be mounted at any convenient point away from the controlled area within the length of the capillary. The least possible amount of capillary should be put into the controlled area.

The bulb should be located so as to be in the average tempera- ture of the area to be controlled.

The bulb should not be attached to any surface but should be held away from the mounting surface by brackets.

Excessive capillary should be coiled and secured in some convenient location close to the switch mechanism.

The proper location of the self-contained thermostat is very important as it depends on average air temperature for proper functioning. The following general rules will help in determining the proper location.

1.Make sure that it is in a place where air circulates freely. This is important.

2.Never install it on or near an outside wall.

3.Keep it away from windows and doors.

4.Don’t locate it too close to cold water pipes, evaporators, coils, etc.

5.Mount it on a post or partitioning wall, but make sure there are no pipes or coils in that wall or directly behind it.

6.If the conduit goes to a warmer room, put rock wool around the wires in the pipe where it enters the control to keep warm humid air out of the switch.

SETTING THE CONTROL

On controls with internal adjustment, the electric power must be disconnected before removing the front cover to change the dial setting. This prevents the possibility of an explosion from arcing at the control contacts while cover is off.

On controls with external knob adjustment, the external knob points to the cut-out temperature.

When replacing the cover on controls with an external knob, set the internal dial and the external dial to the same setting so that hole in dial lines up with pin on the arm that is operated by the knob.
