The owner is responsible for proper installation as  
described above. Please refer to the owner’s manual  
for information regarding installation or use. 

Do not disconnect the control box from the modular unit.

i.

Remove the knobs and faceplate from the control box. Pass the
control box through the countertop cutout, and then through
the apron cutout. This will require the box to be rotated so the
mounting tabs clear the hole. Next, lower and position the
modular section into countertop cutout.

ii.

Before final seating of modular section to countertop, apply
a bead of silicone sealant to the underside of the grey gasket
material supplied on the mounting flange. From underneath,
insert screwdriver into the slots in the Wellslok frame and twist
clockwise to move the ears outward as required to secure the
flange tightly to countertop.

iii.

Mount the control box to apron cutout using #10 sheet metal [or

wood] screws to the facing side where the holes were drilled.

iv.

Run wiring through the conduit knockout to the terminal block,
making connection as shown in the unit’s wiring diagram to the
correct power source.

v.

Mount the front panel onto the control box using the provided
hardware and place the knob on. At this point, you should be
able to power on the unit and check for proper operation.

Do not install closer than 4.125 inches (105 mm) to front wall,  
one [1] inch (25 mm) to back and side walls, and 6.75 inches  
(171 mm) to a surface below the unit. If storage is to be used  
underneath, it is recommended that a baffle be placed 8.5 
inches (216 mm) below the unit to avoid contact with elevated 
temperatures. The unit will need to be accessible from the  
bottom after installation is complete. 

A proper electrical connection based on the units electrical 
specifications will be necessary for installation. 

This must  

be wired and connected by a licensed electrician. Electrical  
installation will need to pass local electrical codes.

i.

ii.

Lay out control panel mounting holes in counter apron using

 the provided dimensions. The mounting holes should be
 0.144 inch (3.7 mm) in diameter [drill size 27].

 iii.

Cut out the holes. On many countertops, reinforcement may
be needed to stiffen the countertop.
