MERCHANDISER LEVELING

-

ly

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. Optional leg levelers can be  
provided for this purpose.

OPTIONAL LEGS

NSF

® 

approved legs replace the leg levelers if 

required by local health codes. The legs raise 
the case 6 inches for cleaning purposes. An 
optional skirt kit can be provided to snap on 
the legs. 

SERIAL PLATE LOCATION

The serial plate is located on the interior left 
wall of the merchandiser. It contains all perti-
nent information such as model, serial number, 
amperage rating, refrigerant type and charge. 
This information will be needed to install, service 
or order parts for the merchandiser.

REFRIGERATION UNIT ACCESS

The lower access panel may be removed by  

lifting the panel straight upward and over the 

screws on which it is hanging. The panel is 

installed by reversing the above procedure.

Ensure lower access panel is flat against the 

floor when installed to prevent air circulation 

problems on self contained merchandisers.

Display is mounted on left 
side of access panel. Be 
careful not to detach cable 
from display when removing 
access panel.

SEALING MERCHANDISER TO FLOOR

If required by local sanitary codes, or if the 
customer desires, merchandisers may be sealed 
to the floor using a vinyl cove base trim. The 
size needed will depend on how much varia-
tion there is in the floor, from one end of the 
merchandiser to the other. Sealing of the lower 
front and rear panels on self contained mod-
els may hamper their removal for servicing or 
maintenance of the condensing unit. 

NOTE: 

Do not allow trim to cover any intake 

or discharge grilles located in the lower front 
panel.
