1. INSTALLATION
1.0 LOCATION
The recirculator must not be tipped over. If necessary, some recirculators can be tilted on the side indicated on
the packaging. If no side is indicated, it cannot be tilted. You must wait at least 2 hours after placing it in an
upright position before starting it up.
It is advisable to unpack the recirculator as soon as possible and check for any possible damages caused during
transportation. If it has been damaged, you must notify the carrier and record the damages on the delivery
note.
To move it to the installation site, you can use a hand truck or pallet jack while ensuring that the recirculator
remains balanced. Depending on the model, the recirculator may be equipped with wheels or rollers to facilitate
its placement.
The area where the recirculator is placed must be clear and clean, avoiding that the fan of the refrigeration unit
absorbs materials that could later accumulate on the condenser fins, reducing the system's efficiency. It should not
be located outside buildings and must be protected from rain and direct sunlight.
Keep the area around the unit free of obstacles to ensure proper airflow. It should be installed in an area with a
volume of at least 12m³. The cooler should not be installed in areas that obstruct passage, such as hallways,
emergency exits, etc.
This machine has a refrigerant charge of group 3, which is less than 150 grams. Therefore, it can be installed in
any type of establishment without additional safety measures, as established by the EN-60335-2-89 standard.
Devices classified as climate class 7 are suitable for the following ambient temperature: maximum 35°C and
relative humidity of 75% HR. Those of climate class 4 are suitable for the following ambient temperature:
maximum 30°C and relative humidity of 55% HR.
The recirculator, in its final placement, should be positioned 7cm away from the wall at the back and 30mm
away from the sides.
1.1 GENERAL CONNECTION
Before connecting the recirculator to the power outlet, ensure that the voltage and frequency of the electrical
supply match the values indicated on the appliance's nameplate.
It is essential that the electrical installation where the recirculator will be connected has an EARTH
CONNECTION, as well as proper protection with circuit breakers and residual current devices (RCDs).

1.3 START-UP
Before plugging in the recirculator, fill the tank with water or water+glycol, depending on its intended use, and
connect all necessary pipes according to the outlets to be used (1 —4).
IMPORTANT:
Use water for positive temperatures.
Use a water+glycol mixture for negative temperatures. Follow the glycol manufacturer's recommended
proportions.
To do this, remove the screw that secures the countertop and pull it upward.

6
Remove the cap from the tank cover to fill the tank with water or water+glycol.
Fill the tank until the level indicator's sphere located on the front of the recirculator reaches its maximum position.
The recirculator is equipped with an overflow inside so that in case the liquid overflows, the device does not
suffer any damage. This excess liquid will be evacuated through the transparent tube located at the back of the
recirculator.
The recirculator is shipped from the factory with all internal pipes connected. You only need to connect the
external pipes that will link the recirculator to the cooling device at the outlets (S1, S2, S3, and/or S4) and inlets
(E1, E2, E3, and/or E4) (remove only the caps from the inlets and outlets to be used). Use insulated pipes with an
outer diameter of 3/8”to prevent condensation. To do this, simply apply slight pressure with the pipe into the
quick connector, and it will create a secure and sealed connection.

7
IMPORTANT: Before proceeding, ensure that all connections are correctly made, and any unused inlets/outlets
have their caps properly connected to prevent leaks.
Once all connections are completed, plug the equipment into the electrical supply and turn on the main switch
located on the front electrical box to the “I”position. The agitation-boost pump will start operating.
To adjust the desired “SET POINT”on the digital thermostat (default set at 5°C), follow these steps:
1- Press any button for 3 seconds to unlock the keyboard.
2- Once unlocked, press the “SET”button.
3- Select the desired cut-off temperatura with the keys .
4- Press the “SET”button again to confirm the chosen temperature.
