A thorough inspection should be made prior to start up to assure that there are no loose nuts, bolts, electrical connections or refrigeration lines rubbing or chafing.
correspond to the actual cabinet temperature due to the bulb location and depending on various conditions, a certain amount of time lag will be noticed between the new setting and the resulting temperature. CONDENSING UNIT – A regular program should be set up for cleaning the fin-and -tube condenser. Normally, this cleaning is required every 3 to 4 months, but the individual store application may shorten or lengthen this time period. Dust and dirt accumulation can cause serious efficiency loss.
LIGHTING – Interior lighting is provided by a cool white fluorescent bulb under the top header (standard), and additional lights under each shelf. The tubes are sleeved to maintain proper heat around the bulb for maximum light intensity and to protect the product in case of breakage. The tubes can be replaced without removing shelves or product. To replace the bulb, twist th e bulb and slide the prongs clear of the lampholder.
CLEANING STAINLESS STEEL SURFACES – Generally soap and water will be sufficient for most cleanings when done often and regularly. When necessary, several cleaning agents can be used. Some of themare Comet, Bab-O, Liquid NuSteel, Cooper’s Stainless Steel Cleaner, and Allen’s Stainless Steel Cleaner. REFRIGERATION – The GSVM models employ a refrigeration system using a hermetic compres sor. The GSVM4060 and GSVM4072 sys tems employ a capillary tube for refrigerant flow control.
Be sure that all s ervice valves are open to allow all of the mixture to be discharged. b. Connect a deep-drain vacuum pump to both the high and l ow side of the system. Pull a vacuum on the system to at least 1500 microns. into the system through a new drier in the charging manifold line. A 16 cubic inch drier is sufficient for this purpose. d. Repeat steps 2 and 3 two more times, the third time evacuating the system to 500 microns. c.
