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 This sign indicates "Risk of Fire/Flammable Materials" due to the use of flammable refrigerant. For this reason, the following warnings should be considered: • Keep the openings for ventilation of the appliance casing or built-in furniture without obstructing it. • Do not use mechanical devices or other means to accelerate defrosting, only those recommended by the manufacturer.

Page 7: Machine Reception
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. LOCATION OF THE ICE MACHINE 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 ECO machines are designed to operate at ambient temperatures between 10ºC and 43ºC (50ºF and 109ºF) and inlet water temperatures between 5ºC and 35ºC (41ºF and 95ºF). -
Page 9: Ice Machine Leveling
2.2. ICE MACHINE LEVELING Use a level on top of ice machine in order to ensure the equipment is perfectly leveled. Screw the leveling legs onto the bottom of the ice machine as far as possible. Move the machine into its final position. Use a level on top of the ice machine. -
Page 10: Minimum Distance To Obstacles
2.4. MINIMUM DISTANCE TO OBSTACLES The machines expel hot air through the grilles, which must be discharged into the room and not accumulate. This is particularly important for the air expelled from the rear of the machines: a space of at least 10cm must be left up to the wall, allowing the air to flow from behind and out so that there is a renewal of this, avoiding the formation of hot air pockets in that area that could reduce the machine's ice production and even activate its protection against excessive temperature and stopping it. -
Page 11: Water Supply Connection
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). It will also have a notable influence on the appearance, hardness and flavor of the ice. -
Page 12: 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. 2.6.2. -
Page 13: Electric Connection
2.7. ELECTRIC CONNECTION • It is mandatory to connect the equipment to ground. To avoid possible electric shock to persons or damage to the equipment, the machine must be grounded in accordance with local and/or national regulations, as applicable. • The manufacturer disclaims any responsibility in the event that damage occurs due to the lack of ground installation. -

Page 24: 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. After the harvest, the ice production starts, so the pump starts working. -
Page 25: Sequence Of Operation
5.1.- SEQUENCE OF OPERATION While the machine is turn on, there is water that need to be evacuated between each cycle. There are 2 possible outlet water, one is if the ice in the storage bin melts (#1) and the other is when the production time ends, the water electrovalve opens and fills the water tray(#2) to renovate the water. - Page 26 The system has a way to evacuate the water inside the water reservoir in a manual way. There is a plug(#9) in one of the plastic tube, by retiring this plug, it is possible to evacuate all the water. Also, the system has a Check valve(#10) that does not allow the water to came back to the water reservoir.

6- ALARMS They detect operational malfunctions. They are indicated with the flashing status Leds LE1-4. During some alarms a second operation retry attempt is carried out and if repeated again, the machine will stop. Signaling should be indicated since the first failure occurs. If the second retry attempt is ok, the signaling will switch off. -
Page 28: 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. -
