Mounting

The controller can be mounted in any position, 

but avoid locations subject to excessive vibration. 

For manual reset models, position the controller to 

permit convenient access to the reset button.

1.   Loosen the front screw and remove  the cover.
2.   Using the two 3/8" mounting keyholes, mount 

the case flush against the duct work or any flat 

surface.

3.   Install the sensing capillary in a horizontal 

serpentine fashion across the downstream side of 

a water coil.

4.   Using the included HMO-4523 capillary clips, 

support the sensing capillary at sufficient points 

to prevent damage from vibration and/or air 

movement. 

 CAUTION

Do not kink or apply excessive force to the capillary 
element.

5.  Make the appropriate connections to the terminal 

blocks. (See the Wiring section.)

Wiring

An opening for installing a connector for 1/2" conduit 

is provided in the bottom of the case.
All wiring should comply with national and local 

electrical codes. Using 14 AWG solid copper wire is 

recommended.
Strip wire ends 3/8", insert the wire ends under 

the cup washers on the switch block, and securely 

retighten terminal screws. 

Wire terminals according 

to the Actuation and Reset section on the next page.
