HUSSMANN CORPORATION, Bridgeton, MO 63044-2483 U.S.A.
START UP
See the specific merchandiser's Data Sheet Set
for refrigerant settings and defrost requirements.
Bring merchandisers down to the operating
temperatures listed on the data sheet.
Each 4 ft (1219 mm) section has its own evapo-
rator coil and pre-set non-adjustable thermostatic
expansion valve (TEV). No adjustment is
required. DO NOT REMOVE THE CAP ON THE
TEVS. This cap is to be removed only for valve
disassembly.
The TEV has been factory set to provide the
recommended performance settings as specified
on the merchandiser data sheets.
STOCKING
Product should NOT be placed in merchandisers
until case is at proper operating temperature.
Proper rotation of product during stocking is
necessary to prevent product loss.
AIR DISCHARGE AND RETURN FLUES MUST REMAIN
OPEN AND FREE OF OBSTRUCTION AT ALL TIMES
to
provide proper refrigeration and air curtain
performance. Do not allow product, packages,
signs, etc. to block these grilles. Do not use
non-approved shelving, baskets, display racks,
or any accessory that could hamper air curtain
performance.
LOAD LIMITS
Each merchandiser has a load limit decal.
Recommended load limit profiles are shown on
the next page.
Shelf life of perishables will be short if load
limit is violated. Overstocking will adversely
affect product temperature and merchandiser
efficiency.
DO NOT BLOCK AIR GRILLE.
START UP / OPERATION
Removal of the TEV cap will result in
refrigerant loss unless the system is first
isolated and the refrigerant recovered.
