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).
Below the minimum temperatures there may be some difficulties
in making the ice flakes. Above the maximum temperature,
compressor life is shortened and output is substantially lower.
Airflow on compact air-cooled machines enters through the front
grille, entering the right front, and exiting the rear. In addition, the
unit is equipped with a rear ventilation grill. Do not obstruct the
front grill with any object.
If the frontal ventilation is not sufficient, the outlet is totally or
partially obstructed or due to its location it receives hot air from
another appliance, we recommend, if it is not possible to change the location ofthe machine, INSTALLING
A CONDENSED MACHINE BY WATER.
IT IS IMPORTANT THAT THE WATER PIPES DO NOT PASS NEAR HEAT SOURCES SO AS NOT TO
LOSE ICE PRODUCTION.
The location should allow sufficient clearance for the water, drain, and electrical connections at the rear of the
icemaker.

9
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. Adjust each leg as necessary to level the ice machine from front to back
and side to side.

10
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.
Connection diagram:
The location should allow sufficient clearancefor water drainage and electrical connections at the rear
of the ice machine.

11
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.
Local water conditions may require water treatment to inhibit scale formation and improve flavor and clarity. If
you are installing a water filtration system, refer to the installation instructions supplied with the filtration system.
The pressure must bebetween 0.1MPa and 0.6MPa (1 and 6 bar). If the pressure exceeds these values, install
a pressure regulator.
In all ECO models the water connection(s) (2 connections) must be dedicated, i.e. there must be only one unit
connected to the water line.
ATTENTION: The machine must be connected tothe pipeline with adequate backflowprotection in accordance
with current national and local regulations.

12
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. DRAIN FORCE CONNECTION
This version of drain force allows an installation of the machine where the drain can be located 30 meters
horizontally and 1.5 meters high from the machine's water outlet.
If the drain pipe runs incorrectly, the pump may not be able to drain the water, because the flow of the
pump may be influenced due to the existence of stored air within the circuit.

13
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.
•The positioning of the appliance must ensure that the electrical supply is not damaged or choked.
•Do not installportable multiple sockets or other portable powersources on the rear of the appliance.
•The machine is supplied with a 1.5 m long cable.
•If the power cable is damaged, it must be replaced with a special mounting cable that will be supplied
by the manufacturer or by the after-sales service. This replacement must be carried out only by a
qualified technical service.
•The machine should be positioned so that there is a minimum of space between the back and the wall
to allow easy and safe access to the cord plug.
•It is advisable to install a remote switch to completely disconnect the machine.
•Protect the outlet. Install appropriate switches, fuses and differential protector.

4.1 REFRIGERATION DIAGRAM
It consists of the following components:
1. Compressor: It sucks in gases atlow pressure from the cold source andsupplies them with pressure
and temperature to be discharged to the hot source.
2. Condenser: receives the gases from the compressor where they give up heat to the mean (air or
water).
3. Evaporator: An evaporator that receives the refrigerant still with liquefied particles where they
evaporate by absorbing heat from the mean. It is an isobaric and isothermal process.
4. Capillar
5. Hot gas valve: is a valve that is installed between the compressor discharge line (high pressure hot
gas) and the low pressure line.
6. Drier: filters and dehydrates the coolant.
