Using the ADAPteR to instAll A MeChAniCAl tiMeR 
to An inteRMAtiC enClosURe
STEP 1 
The original insulator that came with the timer must 
be replaced by the insulator provided with the 
adapter kit. For smaller metal enclosure, cut along 
the horizontal line (1 1/4”) from bottom of the 
insulator provided with the adapter kit. For all other 
enclosures, install the unmodified insulator.
STEP 2
Attach the adapter to the mechanical timer.
Lift the motor wires and carefully insert the plate 
between the wires and the timer. Using the short 
screws, attach the adapter.
Using a flat-blade screwdriver, carefully tighten the 
screws to secure the timer to the adapter.
When correctly attached, the raised edge of the 
adapter should be on the LEFT side of the mechanical timer when viewed from the rear.
STEP 3
Slide the timer on an angle inside of the enclosure, 
gently resting it against the clip.
STEP 4
With the top of the adapter resting on the clip, push 
the top of the timer down until it snaps and locks.
