Fig. 5 Seawater line Refrigerating circuit Cooling water circuit The Ti22 ProX is an air-conditioning system with four basic com- ponents: l Evaporator (liquid heat exchanger): Refrigerant vaporises at low pressure and a temperature below the cooling water temperature. The refrigerant absorbs heat from the cold water circuit in the process.
The compressor compresses the refrigerant vapour, ance purposes. which condenses to a liquid when flowing through the con- l Make sure to mount the Ti22 ProX on an even, horizontal denser cooled with seawater. The seawater absorbs the re- surface.
Installation example The illustration below shows an example of a typical installation of a Ti22 ProX air-conditioning system. In addition to the Ti22 ProX, a further 3 air handlers are shown in this installation example for heating and cooling the respective cabines.
The unit is heavy and must not be carried incorrectly. Installing the condensed-water drain For correct carrying of the Ti22 ProX, make sure to: line l Lift the unit only at the lifting eyes on the stainless steel frame or the condensed-water tray.

If the condenser is soiled, the cooling or heating capacity of the system decreases. The seawater circuit must be cleaned by an expert (such as the installer or your Webasto Service Centre). Cold water circuit 10.2 The operation of the cold water circuit must always be checked, especially after a longer absence.
Check the electrical connections for corrosion to the contacts and firm seating. (See chapter 10.3, "Electrical wiring" on page 22) Check shaft seal of the pumps (seawater, cold water) and replace it if neces- sary (does not apply to pumps with magnetic coupling). 2112898A II Ti22 ProX 23 / 43...
