GALLETTI KIT 3 WAY VALVE MOTORIZED ON / OFF FOR FAN COIL UNITS COD. EYVK8S

The 3-way valve VK kit, ON/OFF motorization, connected to the control panels of the éstro fan coil units, permits to set the room temperature by cutting off the water flow by means of the heat exchanger.

The VK kit is available in various fittings for all éstro fan coil unit models, both for the standard heat exchanger and for the supplemental DF heat exchanger, asoutlined in the table below :

The actuator is to be coupled to a control panel that, depending on the type of system, may be chosen among the following ones

As far as the coupling with the MICROPRO control is concerned, position the temperature probe into the appropriate trap.

The kit comprises:

3-way valve / 4 connections with built-in by pass, made of brass, max. work pressure 16 bar:

Electro-thermal actuator having the following specifications:

- power supply: 230 V

- activation: ON/OFF

- total opening time: 4 minutes

Hydraulic kit for the installation of the valve on the heat exchanger, complete with 2 holders for the balancing and on/off of the fan coil unit.

Raceway, for routing the cables of the actuator inside the fan coil unit.

INSTALLATION

1. Remove the cover cabinet.

2. The 3-way valve VK kit, ON/OFF motorization, is to be installed before powering on the fan coil unit.

WARNING:

- As far as the FU and FC series fan coil units are concerned, remove the condensate tray before installing the valve.

- As far as the fan coil units setup for 4-pipe systems are concerned (2 heat exchangers), the DF heat exchanger is to be installed with hydraulic couplings on the same side as those of the standard heat exchanger. In this case, first install the valve of the standard heat exchanger and then the supplemental DF 1-row heat exchanger.

Each fan-coil requires a switch (IL) on the feeder line with a distance of at least 3 mm between the opening contacts, and a suitable safety fuse (F).

The installer is in charge of carrying out the hatched connections

3. Install the hydraulic unions as indicated in the diagrams of figures 1and 2 that show the following:

    B= water inlet

4. Insert the raceway into the hole at the back of the galvanized side panel of the fan coil unit (figure 3).

5. Route the actuator cable through said hole, fixing it to the cable clamps located on the screw feeder of the fan, until you reach the electrical connections side (opposite the hydraulic couplings side) see figure 4.

6. Wire to the control panel.

7. Reinstall the cover cabinet.
