8 P/N _A START UP See the merchandiser s Technical Data Sheet for refrigerant settings and defrost requirements. Bring merchandisers down to the operating temperatures listed on the data sheet. Each four-foot section has its own evaporator coil and pre-set non-adjustable thermostatic expansion valve (TEV). No adjustment is required. removal of the tev cap will result in refrigerant loss unless the system is first isolated and the refrigerant recovered. Do not remove the cap on the TEVs. This cap is to be removed only for valve disassembly. Removal of this cap during merchandiser maintenance 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. STOCKING Product should NOT be placed in merchandisers until merchandiser is at proper operating temperature. Proper rotation of product during stocking is necessary to prevent product loss.
