Q2SSNM4SPA Merchandisers

SHIPPING SKID

Each merchandiser is shipped on a skid to  
protect the merchandiser’s base, and to make  
positioning the case easier.

 

The skid provides 

protection for both the merchandiser and the 
floor.

Remove the skid by raising one end of the  
merchandiser approximately 6 inches. Block the 
merchandiser securely, and remove the two skid 
bolts from the raised end. Replace the bolts 
with (provided) leg levelers. Repeat this proce-
dure at opposing end. Once the leg levelers are 
secured in place, the merchandiser may be slid 
off the skid and placed in its final location.

DO NOT TILT MERCHANDISER ON ITS 
SIDE OR END WHEN REMOVING SKID.

Once the skid is removed, the merchandiser 
must be lifted —NOT PUSHED— to reposition. 

Check floor where merchandisers are to be set 
to see if it is a level area. Determine the highest 
part of the floor.

Level the merchandiser by all four corners. 
Merchandiser(s) must be installed level to 
ensure proper operation of the refrigeration 
system, and to ensure proper drainage of 
defrost water.

SERIAL PLATE LOCATION

The serial plate is located on the inside of the 
merchandiser’s display area as shown below.

Do NOT remove shipping crate until the 

merchandiser is positioned 

for installation.
