Page 19: Installation
Recommended placement of unit IMPORTANT! ICETECH machines are intended to operate at room temperature between 5°C and 43°C and with water temperature ranging between 5°C and 35°C. You may encounter evaporator/gearbox malfunctions should the machine run at temperatures below the recommended minimum. When running above maximum recommended temperatures you can expect shorter compressor life and decreased production. -
Page 20: Water And Drainage
Granular Ice Technical Service Manual 4.2. Water and Drainage Water quality influences ice hardness, flavour, and quality as well as condenser life. Keep in mind the following points: a) WATER IMPURITIES: Major impurities are eliminated by the two small wire mesh filters provided and installed on either end of the water inlet hose. -
Page 21: Electrical Connection
Granular Ice Technical Service Manual 4.5. Electrical connection • Unit is provided with a 1.5 m cord and Schucko socket (except for models GR 560). • A switch and adequate fuses should be installed. Nominal voltage and intensity are indicated on rating plate as well as on this manual's technical pages. -

Page 23: Inspection And Adjustment Of Water Level In The Tray
Granular Ice Technical Service Manual Be sure voltage and frequency of mains supply is as indicated on rating plate. 1. Set appliance switch to ON position. All elements should be working except for fan (air-cooled machines) which will commence operation only when high pressure activates it. All pilot lights should be switched off except for power display (green), indicating that power is on. - Page 24 Granular Ice Technical Service Manual Expansion valve. DO NOT TOUCH THE EXPANSION VALVE. Water Level The purpose of maintaining proper water levels is to allow adequate water flow to the evaporator. A water level sensor has been incorporated to shut off unit until required minimum water level is achieved.
- Page 25 Granular Ice Technical Service Manual (exit temperature). • If mains water temperature exceeds 32°C, the above values of high pressure and water temperature at exit will be higher. ADJUSTMENT: High pressure (and water temperature) can be decreased by opening valve (turn screw clockwise).
- Page 26 Granular Ice Technical Service Manual This safety device trips when pressure is too high. Pressure might reach the set limit of 27 Kg/cm2 when: a) Air circulation is not sufficient, room temperature is too high, condenser is dirty or fan motor is broken. (air-cooled models) b) Insufficient water in the cooling circuit, inlet water temperature is too high or fan motor is broken (water -cooled models).

Granular Ice Technical Service Manual 9. MAINTENANCE AND CLEANING PROCEDURES WARNING: Unit should always disconnected during maintenance/cleaning procedures. Water Condenser 1) Disconnect machine. 2) Close water faucet. 3) Disconnect water entry/exit from condenser. 4) Prepare a solution of 50% phosphoric acid in distilled water. 5) Distribute solution through condenser. - Page 32 Granular Ice Technical Service Manual 9) Disconnect machine, remove plug, open faucet and let water run for 2 to 3 minutes. 10) Close faucet, place plug, open faucet and connect the machine. **At this point sanitary cleaning starts 11) Slowly add bleach to water trough for at least 5 minutes. Allow machine to make ice for at least 15 minutes.

Page 34: Special Advise Concerning R-404 Refrigerant
Granular Ice Technical Service Manual In order to avoid damage to the gear-box, the safety trip is very sensitively adjusted and may trip easily. You may teach the end user to re-connect the machine (by inserting a pen/screwdriver through the front grille blades). This is best done after a one hour pause. Should the machine trip on a regular basis (more than once a week), the end user must get in touch with the service department. -
