INSTALLATION

EVACUATION OF AIR DURING THE FILLING OF THE PLAN

• Open all system interception devices (manual or automatic);
• Start filling by slowly opening the water tap of the plant water;
• Operate (using a screwdriver) on the battery drain (Fig.1);
• When water starts bleeding from the breather valves of the appliance, close them and continue charging until the rated value for the plant is reached. Check the hydraulic sealing of the gaskets. It is advisable to repeat this operation after the appliance has been operating for several hours and periodically check the system pressure.

Fig. 1

NOTES ABOUT VALVE ACTIVATION

The appliance includes a condensation drain pump as part of the standard supply. Using a thermal contact sensor (TC), this pump always operates when the appliance is filled with cold water, thus in the cooling phase.

The pump remains stationary when the temperature of the water entering the bank exceeds 25\ °C and no condensation is formed. Connect the TC sensor to the cooling coil inlet pipe. If the valve kit accessory is used (this is obligatory if the unit is used for cooling), always place the sensor on the cooling exchanger inlet.

The valve can be controlled by means of the switch or the two thermostats supplied as accessories, depending on the type of installation.

INSTALLATION BACINELLA CONDENSA COLLECTION
