Service Information Filter-Drier Installation Any time the sealed system is opened and the refrigerant charge is removed, the liquid line filterdrier must be replaced and the system thoroughly evacuated before recharging. CAUTION DO NOT unbraze the old filter-drier from the system. This will vaporize and drive moisture from the desiccant back into the system. The old filter-drier should be cut out of the system.
Service Information Equipment Needed for Evacuation & Recharging: • Heated charging cylinder • Standard 3-port manifold gauge set: - 4 charging hoses - Tee fitting with valve core stem removed (Robinair No. 40396) - Hand shut-off valve (Robinair No.40380) • Two stage vacuum pump • Process tube adapter kit (Robinair No.
Service Information 5. 6. 7. Close hand shut-off valve to vacuum pump. Watch compound gauge for several minutes. If reading rises, there is a leak in the system, go to step 6. If no leak is indicated, stop vacuum pump. System is now ready for charging. If a leak is indicated, stop vacuum pump and introduce a small charge of refrigerant into system by cracking valve on bottom of charging cylinder until system is pressurized to 40 or 50 lbs psig.

Service Information NOTicE Instructions given here are furnished as a guide. Persons attempting to use these instructions to make repairs to the sealed refrigeration system should have a working knowledge of refrigeration and previous training on sealed system repair. Verify Refrigerant Type In The System CAUTION R-134a and R-12 are completely incompatible. Before starting any sealed system repair, it is extremely important to check serial plate of product to verify the type of refrigerant in the system.
Service Information At the earliest stage of development work on R-134a, tests were carried out on a different type of synthetic oil known as Poly-Alkaline Glycol (PAG). This oil is also used in certain air conditioning systems for cars. PAG and Ester oil DO NOT mix with one another. Service equipment used for R-134a / Ester oil must not come into contact with PAG. Water In The Refrigeration System To achieve the required 29.
Service Information CAUTION If you use a vacuum pump with mineral oil to evacuate an R-134a system, it is ABSOLUTELY ESSENTIAL to have a shut-off valve between pump and your manifold gauge set as shown in Figure E2. The hand valve must be closed during all times when vacuum pump is not operating. This will prevent migration of mineral oil vapor into R134a/Ester oil system. If vacuum pump should stop during evacuation for any reason, the hand pump shut-off valve must be closed immediately.

Service Information Inhalation Toxicity Spills or Leaks HFC-134a poses no acute or chronic hazard when it is handled in accordance with DuPont recommendations and when exposures are maintained at or below the DuPont Acceptable Exposure Limit (AEL) of 1,000 ppm (8 and 12 hour Time-Weighted Average or TWA). If a large release of vapor occurs, such as from a large spill or leak, the vapors may concentrate near the floor or low spots and displace the oxygen available for breathing, causing suffocation.
Service Information Always wear protective clothing when there is a risk of exposure to liquid HFC-134a. Where splashing is possible, always wear eye protection and a face shield. Combustibility of HFC-134a HFC-134a is nonflammable at ambient temperatures and atmospheric pressure. However, tests have shown HFC-134a to be combustible at pressures as low as 5.5 psig (139.3 kPa absolute) at 177°C (350°F) when mixed with air at concentrations generally greater than 60% volume air.
Service Information Ice Cube Thickness Adjustment Interval - As Required Ice thickness adjustments are made using the control panel as follows: 1. To enter the thickness adjustment mode: a. Touch and hold the UP ARROW button. b. Touch and release the DOWN ARROW button three times, then release the UP ARROW button.

Service Information Upon initial startup, this unit will enter mode number 5 which is a three-minute water fill regardless of the thermistor temperatures. This only occurs when the intial startup is caused by a power-up of the main board. Following the three-minute water fill, the unit moves into mode 1 which is the freezing mode. In this mode the water is pumped from the sump trough over the ice maker grid by the circulation pump.
Service Information Model CLR2160 WARMER and COLDER for five seconds. We’ll assume the display showed 38°F for this example. Go to service mode #24 and adjust the setting to that number. This will allow the bin to shut off at this ice level. This temperature needs to be checked after the door has been closed for at least 10 minutes in order for the thermistor temperature to stabilize. Poor ice quality Too little ice A defect in the drain from the unit will cause water to stop draining from the unit.
