Tools Required (Not Included):

7mm and 10mm Ratchet, Socket Driver, or Wrench

Phillips Head Screwdriver

Rubber Mallet

Appropriate Drill with Assorted Bits

M10 or 7/16” Lag or Anchor Bolts and Washers for Anchoring 

Rack into Wood or Concrete

Preparing for Installation:

Determine the best area to install the rack system. Ensure the 

location meets building code requirements, and that all safety and 

clearance requirements for the appliance(s) to be mounted to the 

rack are met.

Installing the Rack System:

1. Move the rack components to the installation location. Ensure 

you have all the components for the installation.

NOTE: 

DO NOT lose these components. Replacements ARE NOT 

included in this kit.

2.  Set  the  base  feet  in  the  installation  location.  Verify  finished 

installation clearances will meet the service clearance requirements 

of the appliance(s) to be mounted on the rack.

3. Use a Phillips Head Screwdriver and eight (8) screws to install 

the four (4) angle supports to the two (2) base feet. See Figure 1.

NOTE:

 DO NOT fully tighten the screws. Doing so will make it 

difficult to install the vertical posts and waste time.

Remove all items from the packaging and ensure that all parts 

and accessories are included in the kit. Any claims for damage 

or shortage in shipment must be filed immediately against the 

transportation company by the consignee.
