Condensate Evacuation - Airwell K OG LN Manual De Instalación Y De Mantenimiento

For connecting the coils the use of stop cock valves with flexible pipes is recommended.
It is imperative to envisage a support of these pipings independently of the cassette.
The connection must not be over tightened.
It should be noted that over tightening the connections can cause excessive material
constraints during high temperature operation.
A counter wrench must be used for tightening the pipe work.
For the system to operate in complete safety, regulating valves must be fitted, if they are not already
fitted at the factory.
The use of regulation valves (factory-fitted, supplied as an accessory or by the client) is mandatory to ensure that
the appliance operates correctly.
The installation and operating conditions require the MANDATORY fitting of a valve ON the unit
OR/AND upstream in the hydraulic circuit. This is to prevent chilled water from circulating in the
appliance when the fan is not operational (condensation issue) or to prevent the simultaneous
circulation of chilled water and hot water in a 4-pipes exchanger.
The hot water coil air vent must be done through the water outlet
connection (8 ).

The first time the cassettes are filled with water to check the tightness of the circuits,
they can be filled on a temporary basis, without power being connected to the unit. If,
on the other hand, continuous water circulation is planned, the units must be connected
to the power supply to ensure condensate drainage by the draining pump and to avoid
the condensate tray overflowing.

10.1. CONDENSATE EVACUATION

To ensure effective condensate evacuation, the downward slope
must be 1 cm per metre without any restricted or ascending section.
The condensate extraction height is limited to a maximum of 0.60
metre.
For heights above 0.60 m, an auxiliary condensate pump with a
level regulator should be installed.
Furthermore, a siphon with a height of at least 50 mm must be
provided to avoid any unpleasant odours in the room.
The condensate evacuation pipe must be heat insulated to a thickness of 5 to 10 mm with insulating material such
as polyurethane, propylene or neoprene (Fireproofing classification: M1) to prevent condensation.
If several cassettes are installed in the room, the evacuation system can be designed as illustrated below.
THE CASSETTE MUST ALWAYS REMAIN CONNECTED TO ELECTRICAL SUPPLY TO ALLOW
THE DRAINAGE OF WATER CONDENSATS.
