Page 4: Introduction
1. INTRODUCTION This manual has been created to provide the installer with information to carry out a correct installation and for the effective maintenance of the machine. Furthermore, the user will find in the document a section referring to the cause of possible incidents, as well as complete information on their resolution. - Page 5 It is mandatory to connect the equipment to ground to avoid possible electric shocks to people or damage to the equipment. The machine must be grounded in accordance with local and/or national regulations. The manufacturer disclaims any responsibility in the event of damage occurring due to the lack of ground installation.
- Page 6 In case of refrigerant leak: • Do not generate a flame in the surroundings of the appliance. • Do not turn on/off switches or connect/disconnect plugs in the area of the appliance. • Do not use a direct flame. • Immediately ventilate the area of the appliance by opening doors and windows.

1.2. MACHINE RECEPTION Inspect the outer packaging. In case of damage, make the corresponding claim to the carrier. To confirm the existence of damage, unpack the machine in the presence of the carrier and note any damage to the equipment on the receipt document or transport document. Always indicate the number and model of the machine. -
Page 8: Installation
2. INSTALLATION 2.1. ICE MACHINE LOCATION This ice maker is not designed to be used outdoors. The ice maker should not be located next to ovens, grills, or other equipment that produces a lot of heat. Incorrect installation of the equipment may cause damage to persons, animals or property, for which the manufacturer cannot be held responsible. -
Page 9: Ice Machine Leveling
2.2. ICE MACHINE LEVELING Use a level on the top of the ice maker to ensure the equipment is perfectly level. Screw the leveling feet into the bottom of the ice maker as far as they will go. Place the machine in its final position. -
Page 10: Water Supply Connection
Connection diagram: The location should allow sufficient clearance for water drainage and electrical connections at the rear of the ice machine. 2.5. WATER SUPPLY CONNECTION The quality of the water supplied to the ice maker will influence the time between cleanings and ultimately the life of the product (mainly on water-cooled units). -
Page 11: Drain Connection
2.6. DRAIN CONNECTION 2.6.1. GRAVITY DRAINAGE The drain must be located lower than the level of the machine, at least 150mm. It is advisable that the drain hose be 30mm in inner diameter and with a minimum slope of 3cm/meter. 2.7. -
Page 12: Prior Control And Start-Up
The voltage is indicated on the nameplate and in the technical specifications section of this manual. A voltage variation greater than 10% indicated on the nameplate may cause damage or prevent the machine from starting. 3. PRIOR CONTROL AND START-UP 3.1. -
Page 13: Start Up
3.2. START UP Once installation instructions have been followed (ventilation, site conditions, temperatures, water quality, etc.), proceed as follows: 1. Open the water inlet. Verify the no existence of leakages. 2. Open the door and remove the protection elements on the shield. 3. -

Page 15: Hydraulic Equipment
4.2 HYDRAULIC EQUIPMENT • Water inlet valve: Controlled by the control board; supplies water from to the tank. • Water tank: Maintains the water level by means of a level tube. • An overflow allows the water level in the tank to be maintained at the start of a new cycle. A drain plug is also provided to facilitate the draining of the tank and its cleaning. -

4.4.5 FUNCTIONS OF THE INTERNAL BUTTON ON THE PCB Function depends on the unit status: • Start up timer: Finish initial delay y passes to ice production stage • Ice production. Switches to harvest • Harvest. Switches to Ice production Wash cycle activation Keep pressed the button while switching on main front switch. -
Page 21: Sequence Of Operation
5. SEQUENCE OF OPERATION Once you connect the machine there is a time delay of 140” during which the water valve is activated to ensure the water tray is filled. Compressor, pump will be off. Once the time is up, it continues with a harvest cycle and the compressor starts. During take-off, the water tank where the turbines are located is filled and the water above the set level goes out through an overflow. -
Page 22: 6- Alarms
6- ALARMS They detect operational malfunctions. They are indicated with the flashing status Leds LE1-4. In case that a machine stop has been caused by alarm, the reset is done by switching OFF and ON the main switch. If the dip-switch 11 OFF, time alarms are not to be followed. 6.1 SAFETY HIGH PRESSURE SWITCH When the pressure contact (P) trips, instantly, all outputs switch over to off position. -
Page 23: Maintenance And Cleaning Procedures
7. MAINTENANCE AND CLEANING PROCEDURES It is the User’s responsibility to keep the ice machine and ice storage bin in a sanitary condition. Ice machines also require occasional cleaning of their water systems with a specifically designed chemical. These chemical dissolves mineral build up that forms during the ice making process. Sanitize the ice storage bin as frequently as local health codes require, and every time the ice machine is cleaned and sanitized. -
Page 24: Cleaning The Air Condenser
7.1 CLEANING THE AIR CONDENSER 1. Disconnect the machine. 2. Disconnect machine and close water faucet. 3. Remove the front grid by removing the two screws placed at front side (see figure). 4. Clean condenser using a vacuum cleaner, soft brush or low pressure air. Clean from top to bottom, not side to side. -
Page 25: Water Leakage Checking
7.4 WATER LEAKAGE CHECKING This must be done whenever maintenance is carried out on the machine: check all water connections, braces, tubes and hoses in order to eliminate leaks and prevent breakages and flooding. 7.5 CLEANING THE HYDRAULIC SYSTEM 1. Set the switch to the OFF position after ice falls from the evaporator at the end of a harvest cycle or set the switch to the OFF position and allow the ice to melt off the evaporator. - Page 26 Return it to their original position to avoid water spill. 2. Prepare a solution of an appropriate product for the cleaning of ice machines (lime). Do not use hydrochloric acid. We recommend the use of any approved scale removal product prepared according to the manufacturer’s instructions as for example CalKlin.
- Page 27 Pulsador 4. Remove the universal Pulsar cap to drain and purge out the ice machine scale remover and residue. Replace it. 5. Mix enough cleaning solution (as in point e) to clean parts and interior food zone surfaces. 6. Clean all surfaces of the shield (#3) with the cleaner solution using a brush (not a wire brush) or cloth.
