Any cabinet malfunction or housekeeping problem that creates a slip/fall hazardaround or under the cabinet should be corrected immediately.If moisture or liquid is observed around or under a Master-Bilt cabinet, an immediate investigation should be made byqualified personnel to determine the source of the moisture or liquid. The investigation should determine if the cabinet ismalfunctioning or if there is a drainpipe leaking.CABINET CLEANING PROCEDURESWARNING!To avoid electrical shock, disconnect main power supplies to the merchandiserbefore beginning this procedure. May have more than one disconnect switch.The exterior of the cabinet should simply be wiped clean with a Warm damp cloth daily. This will be sufficient to keep themerchandiser looking its finest. Do not use a brush, scouring pad, or any abrasive material on the painted surfaces!To clean the interior of the cabinet, the condensing unit and power to the merchandiser fans, lights, and heaters should beshut off. Disconnect all power before cleaning! All product in the cabinet should be removed and stored in anappropriate facility. All shelving, trays, Pans, etc. should be removed and cleaned separately. For cleaning the airdischarge honey comb in the back wall. Romove the honey comb retainer, that’s hold the honey comb in place, byunscrewing all the thrump scews. Gently pull out all the honey combs. Wash with hot warm water only and carefullyreplace it back. Be sure the honey combs is dry before putting it back inplace to provent from ice build up blocking the airflow.The interior (as well as the exterior) of the cabinet may be cleaned with a germicidal detergent at the manufacturer’srecommended concentration. Do not use any ammonia-based products as this may damage the electricalcomponents in the cabinet. Again, do not use a brush, scouring pad, or any abrasive material on the painted surfaces.Use a soft brush or cleaner pad for built-up dirt, stains, or spills. Remove only the necessary mechanical parts to accessthe evaporator coil and fan housing. Care should be taken not to unnecessarily soak fan motors, electrical connections,controls, or any wire raceway. Wipe all surfaces with a damp cloth. A sanitizer should then be thoroughly sprayed ontothe surfaces and again wiped with a damp cloth.Remove only the necessary mechanical parts to access the condenser coil and compressor housing. Care should againbe taken not to unnessarily soak fan motors, electrical connections, time clock, ballasts, or any wire raceway. Check thecondenser coil to insure that it is not clogged with dirt, dust, or lint. A dirty or clogged condenser coil will result indiminished performance of the cabinet. The condenser should be brushed with a plastic bristled brush. For dust or dirtthat has accumulated deep inside the condenser, use compressed air to blow the dirt through the coil. Do not let dust ordirt accumulate on the fan blades. If dust or dirt is noticeable, simply wipe the fan blades with a damp cloth as with othersurfaces. After cleaning, replace any equipment that was previously removed and started the condensing unit and returnpower to the lights, fans, and heaters.CLEANING: As a regular maintenance routine, the condenser coil should be cleaned approx every 6 to 12 months,depending on store conditions.Keep the equipment clean and sanitary so it will meet your local sanitation codes. Wipe up all spills, clean with water anda mild detergent, then rinse with clean water. Wipe the exterior and gasket area as needed.6
Cabinet Monthly Checklist1. Check condenser coil, clean if necessary.2. Check service valve packing for leaks evident by oiltraces.3. Check for obstruction restricting air flow over theevaporator coil and the condenser coil. Insure thatthe air intake is not obstructed.4. Check for excessive noise5. Check for proper temperature, adjust ifnecessary.6. Check for proper operation sequence innormal refrigeration cycle and defrost cycle(when applicable).EXTERNAL CLEANINGClean the front and side glass panels, and the end panels and serving surfaces with warm water and a milddetergent. Never use steel wool, abrasives, glass paper, or similar products. Never use acids, chlorines, ammonia,etc. as it could damage the cabinet surface.WEEKLY DEFROSTINGFor enhanced performance and efficiency, the Master-Bilt GEL series should be defrosted weekly for an extendedperiod (at least twelve hours). To achieve this defrost, the cabinet should have a manual defrost first. Press andhold the button labeled “MAN DEF” for ten seconds on the control. (See the section of this manual labeledELECTRONIC REFRIGERATION CONTROL). After the cabinet starts a defrost cycle, wait about 15 minutes, thendisconnect the power supply to the cabinet and let the cabinet stand for this prolonged period. This will ensure thatall ice has been defrosted and drained from the evaporator and storage area.MECHANICALRemove front and rear grille and check refrigeration lines to see that they are free (not touching each other orcompressor). Spin condenser fan blade to see that it is free.Check that all service valves (2) are open. The springs are secured for shipping by either tightening bolts. Loosenthe hold-down bolts so that the compressor floats freely. Check all refrigeration lines and electrical conduit forrubbing or chaffing, paying particular attention to area where lines enter the cabinet.Remove cabinet from crate base and slide into location. Cabinet must be level from side to side and front to back forcorrect draining of coil pan and for self-closing doors to operate correctly.7
