START UP / OPERATION

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.

!CAUTION

Removal of the TEV cap will result in

refrigerant loss unless the system is first isolated and the refrigerant recovered.

The TEV has been factory set to provide the recommended performance settings as specified on the merchandiser data sheets.

NOTICE

Do not put heavy objects on case

because it could lead to structural damage.

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.

LOAD LIMIT

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.

!CAUTION

At no time should merchandisers be

stocked beyond the load limits indicated.

Improper stocking can cause poor

performace that results in spoiled food.
