Each canister must be able to mount 
independently to the underside of the 
microwave at the midpoint between center 
of the front and back burners on each side 
(left and right) at a distance of 15-32” 
(38-81 cm) above the surface of the stove.

REQUIREMENT - MOUNTING

To accommodate many different 
microwave configurations, 
each ClickBar

 contains five (5) 

magnets. At least three (3) of the 
five (5) magnets must make full, 
strong contact with a flat surface 
on the underside of the microwave.

NOTE:

 Magnets making contact 

with ridges, support ribs, valleys, 
non-magnetic parts, and rounded 
or angled sections should not be 
counted on.

STEP 6

Place the enclosed decal under or near 
the microwave where it can be seen. 

VENTS: Canisters should not be mounted over any vents, if possible. The ClickBar and magnets may do so, but only if it permits the device to 
meet the three (3) magnet minimum requirement. Some metallic parts under the microwave may not hold a magnet.  
LIGHTS: Neither glass nor plastic light covers will hold a magnet. Canisters or ClickBars may obstruct the light, provided that the three (3) 
magnet requirement has been met, and the unit is secure.

STEP 5

Due to variances in stove design and 
element layout, the canisters may not 
perfectly align with each other under 
the microwave.

STEP 4

Once you have found an acceptable 
location, lift the ClickBar upwards. 
Confirm that three (3) of the five (5) 
magnets are securely fastened.

STEP 2

Raise canisters from underneath to the 
spot directly above under microwave 
without attaching the ClickBar. 

Use one hand to hold the canister in its 
final position, while using the other hand 
to swivel the ClickBar to the optimal 
mounting position (see precheck section).

STEP 3

Below are just some of the possible scenarios. Microwave detail is not drawn to scale.
