Page 3: Installation Guidelines
Installation Guidelines Note: Installation should be performed by a trained Service Technician. For proper operation of the ice machine, the following installation guidelines must be followed. Failure to do so may result in loss of production capacity, premature part failures, and may void all warranties. -

8. Oil the fan motor if the motor has an oil fitting. Cleaning and Sanitizing Harvest problems may occur if the following procedures are not performed every 6 months. 1. Remove the ice machine front panel. 2. Make sure that all the ice is off of the evaporator. If ice is being made, wait for cycle completion, then turn the machine “OFF”... - Page 5 Cooling System...

During the icemaking stage, water is pumped from the water trough to the water distribution tube. The distributed water flows over the surface of the cold evaporator where the purest water is converted to ice. The unfrozen water returning to the trough.

Electrify Status For The First Time As the icemaker is properly installed. switch on the water tap, let the water trough full (reach on the level), then turn the Power switch to the ON position on the back panel. The icemaker will start working automatically In this status, the time is fixed about 3 minutes.

Troubleshooting ELECTRICAL SHOCK HAZARD Disconnect Electrical Power Before Beginning Removal of Parts Before Maintenance 1. Be sure the electrical supply is 115 VAC, 60Hz, 15A and is properly grounded to protect maintenance personnel against electrical shock. 2. Are any electrical leads loose? Danger of short circuit? If so, disconnect power. Basic Troubleshooting Some problems can be pinpointed through the service technician’s senses of hearing, sight and touch. -

3. Replacing the hot gas valve, drier and evaporator Remove the top panel. Locate the drier and hot gas valve, open weld, replace the drier and hot gas valve, weld, recover refrigerant, evacuate and weigh in the charge on the nameplate. Reverse the above steps to reassemble. - Page 23 Compressor Check Compressor and Start Components The compressor should run during the entire cycle. If the machine is in the ON position but the compressor is not running, check the compressor contactor to see if it is engaged. If the contactor is not engaged, the problem is not with the compressor or the compressor start components.
- Page 24 Thermostatic Expansion Valve (TXV) The thermostatic expansion valve meters the flow of refrigerant into the evaporator changing its state from a highpressure liquid to a lowpressure liquid. This drop in pressure causes the refrigerant to cool. The cooled refrigerant absorbs heat from the water circulating over the evaporator. As the evaporator fills with liquid refrigerant, the evaporator becomes colder.
- Page 25 functioning properly. If the hot gas valve leaks during the freeze cycle, ice will not form on the top of the evaporator and suction pressure will be higher than normal. To check if the hot gas valve is leaking, let the machine run in the freeze cycle for approximately 5 minutes. Now feel the temperature between the inlet and outlet of the valve.
- Page 26 where the temperature and pressure of the vapor are increased. The high temperature, high pressure vapor flows to the condenser where the heat is removed, causing the vapor to return to the liquid form, making the refrigerant ready to flow back to the evaporator to pick up more heat. ice machine use R134a or R404a refrigerant.
- Page 27 Bin Control Operation The bin control is used to shut the machine off when the bin fills with ice. The bin control must be checked upon installation or initial startup and when performing maintenance. Adjustments are notcovered under warranty. There is one bin switch for each evaporator. The actuator arm of the bin switch comes in contact with the splash curtain.
