CONNECTION DIAGRAM
Thread the support legs to the base of the machine in the housing set to such end and regulate the height as to have the
equipment perfectly levelled.
3.1 WATER AND DRAINAGE
Water quality has a remarkable influence on the appearance, hardness and flavour of the ice as well as, in the machines con-
densed by water, on the life of the condenser.
3.2 CONNECTIOS TO THE WATER NETWORK
Use a flexible food grade pipe.
Pressure should be established between 1 and 6 Bar (0.1 and 0.6 MPa / 14 and 85 psi. If pressures overpass such values,
install the necessary corrective devices.
3.3 CONNECTION TO DRAINAGE
Drainage should be located lower to the machine level, at 150 mm (6") minimum.
It is convenient that the drainage pipe is of 30 mm (1-1/8'') of interior diameter and with a minimum gradient of 3 cm (1.18 in)
per meter (see figure).
IT IS MANDATORY TO GROUND THE EQUIPMENT.
To avoid possible discharges on individuals or damages to the equipment, the machine should be grounded pursuant local and/or national regulations as the case may be.
THE MANUFACTURER SHALL BE HELD HARMLESS IN CASE OF DAMAGES ARISING DUE TO THE LACK OF THE GROUND INSTALLATION.
The machine is supplied with a 1.5 m (4.92 feet) cable of length. In case the supply cable is damaged, it should be replaced by a cable or special assembly to be furnished by the
manufacturer or post-sale service. Such replacement should be performed by qualified technical service only.
The machine should be placed in such a way that allows a minimum space between the back and the wall in order to guarantee an easy and a risk free access to the plug.
Safeguard the socket. It is convenient to install adequate switches and fuses.
Voltage and tension are indicated on the nameplate. Variation on voltage above the 10% stated on the nameplate could result on damages or prevent the machine from start-up.
ATTENTION: The appliance requires an independent power supply of proper capacity. See the nameplate for electrical specifications. Failure to use an independent power supply of
proper capacity can result in a tripped breaker, blown fuse, damage to existing wiring, or component failure. This could lead to heat generation or fire.
4| START-UP
4.1 PREVIOUS CHECKUP
• Is the machine leveled?
• Are voltage and frequency the same as those on the nameplate?
• Are the discharges connected and operating?
• ** If air condensed: Are the air circulation and site temperature appropriate? ** Is water pressure appropriate?
Note: In case input water pressure is higher than 6 Bar (0.6 MPa / 85 psig), install a pressure regulator.
ROOM
MAXIMUM 43ºC / 109ºF
MINIMUM 5ºC / 43º F
4.2 START-UP
Once the installation instructions are followed (ventilation, site conditions, temperatures, water quality, etc.), proceed as follows:
1. Open the deposit door to access the installation kit.
2. Connect the drainage following the instructions indicated in this manual.
3. Connect and open the water inlet. Verify whether leakages.
4. Connect the machine to the electrical network.
5. Turn on the front switch. Verify the pilot lights.
6. Verify that there are no vibrations or frictions on the elements.
7. Verify the start of ice production.
The technical installer shall invoice traveling costs, hours and materials used on such operations.
4.3 LONG STOP. WATER TRAY DRAINAGE.
For two days or longer stops, to drain the water in the tray is recommended.
For this porpouse. When the machine is running, open the front door, press and release the button placed at the internal steel front.
Water tray will tilt and go up again. Then switch off the front main switch.
5| MAINTENANCE AND CLEANING INSTRUCTIONS
CAUTION: Instruct the user about maintenance, informing that maintenance and cleaning operation as well as damages due to the lack of such operations are not included in the
warranty.
If a good maintenance is performed, the machine will continue producing a good quality of ice and will be free of damages.
Maintenance and cleaning intervals will depend on the conditions of the site and water quality.
CAUTION: The ice machine's water system should be cleaned and sanitized at least twice a year.
On dusty environments, it might be necessary to clean the condenser on a monthly basis.
MAINTENANCE AND CLEANING PROCEDURES
WARNING: Wear rubber gloves and safety goggles when handling Ice Machine Cleaner or Sanitizer.
WARNING: Unit should always be disconnected during maintenance/cleaning procedures.
Sanitize the ice storage bin as frequently as local health codes require, and every time the ice machine is cleaned and sanitized.
5.1 WATER CONDENSER
1. Disconnect the machine.
2. Disconnect the water inlet and outlet from the condenser.
3. Prepare a solution at the 50% of phosphoric acid and distilled or demineralized water.
4. Make the solution circulate through the condenser. (The solution is more effective if hot - between 35ºC [95ºF] and 40ºC [104ºF]).
WARNING! DO NOT USE HYDROCHLORIC ACID.
