Mounting and  
Installation  
General Guidelines  
Locate the sensing element in the downstream side of the coil.  
Locate the case and bellows where the ambient temperature is always warmer than  
the setpoint.  
Install the thermostat so that the reset button is readily accessible and the element  
bellows points down.  
Install as much of the bulb as possible in a horizontal plane. If too much of the bulb  
is vertical, it will not operate properly.  
Avoid sharp bends or kinks in the sensing element.  
Large walk-in Ducts  
(Figure 1)  
1. Attach the mounting bracket to the thermostat with the two round head screws  
provided.  
2. Mount the two perforated steel strap hangers inside the duct with the wide part of  
the hanger strap parallel to the air flow.  
3. Drill a hole in the side of the duct. With the bulb still coiled, thread the bulb through  
the hole using a rotary movement.  
4. Mount the thermostat on the outside of the duct.  
5. Carefully uncoil the bulb avoiding sharp bends or kinks in the sensing element.  
6. Mount the bulb in a horizontal, serpentine manner, attaching the bulb to the strap as  
shown in detail in Figure 1.  
The installation is complete.  
NOTE: For an alternate method of mounting, use coil clips (Part Number 356-115) in  
the fins to hold the bulb in a horizontal, serpentine pattern.
