Page 8: Installation
The air conditioner works according to a compression cycle of refrigerant, sea water and boat room air. The machine has two mode, cooling mode (for the hot seasons) and heat pump mode (for the cold seasons). In cooling mode, the air inside the cabin is drawn in by a fan and passed through the evaporator for to be cooled and dehumidified. -
Page 9: Fixing The Conditioner
For fixing the machine, use screws suitable for the surface used for fixing. Installation of the condensate drain piping With the MACS the ambient air is dehumidified, the water is collected from the anti- condenser tray. The air conditioner is equipped with two anti-condensation drains, it is possible use only one of two. - Page 10 SEA WATER LINE Sea water intake Sea water pump Ball valve MACS conditioner Filter Sea water discharge ATTENTION Follow the instructions below for correct installation of the system 1) Sea water intake: The sea water intake, must be installed oriented towards the bow and as close as possible to the keel and as low as possible with respect to the waterline, in order to avoid the entry of air in the circuit.

The height, however, must not be excessive, to minimize the noise produced by the water jet. -
Page 12: Air Distribution Circuit
Vitrifrigo return air grilles are equipped with a filter. If grilles other than the Vitrifrigo accessory kit are used in which the air filter is not present, a filter must be installed in front of evaporator or in the grille. -
Page 13: Electrical Box
The forced air (driven by the fan) can also be conveyed to multiple supply grilles, or in the only one grille of system. For MACS 12 and MACS16, Vitrifrigo has an available kit for the second supply grille in case the machine wants to be used for two distinct environments. -
Page 14: Electrical Panel Assembly
Electrical panel assembly The MACS electrical panel is supplied connected to the machine. Check it before switch on the machine that all components are plug in according to annex 6 fig 6a. The installer will only have to make the electrical connection of the hydraulic pump, the control panel and the general power supply of the electrical panel. -
Page 15: Electrical Connection Of The Sea Water Pump
The control panel must be connected to the electronic board of the air conditioner (inserted in the electrical box) via the 4-pole RS485 cable supplied. Make sure that the terminals of the connection cable are well hooked both on the electronic board and on the back of the panel. -

• If there are several air conditioners on the boat, and they have a common water circuit, the pump will be powered directly from the network (and not from the electronic board), therefore it will be necessary to provide a special differential magneto thermic switch and a fuse of protection correctly sized (refer to the pump label). -
