WATER PIPE-WORK

Checking the water circuit

NB: The 3-way valve is not supplied with this system

Before continuing the installation of the unit, check the following points:

• The maximum water pressure is 10 bar.

• Shut-off valves are not included with the unit. To facilitate service and maintenance, please install one at each water inlet/outlet. Mind position of the shut-off valves. Orientation of the integrated drain and fill valves is important for servicing.

• Take care that the components installed in the field piping can withstand the water

pressure.

NEVER USE UN-COATED PARTS IN THE WATER CIRCUIT. EXCESSIVE

CORROSION OF THESE PARTS MAY OCCUR AS COPPER PIPING IS USED IN THE

INTERNAL WATER CIRCUIT OF THE UNIT.

WHEN USING A 3-WAY VALVE OR A 2-WAY VALVE IN THE WATER CIRCUIT. THE RECOMMENDED MAXIMUM CHANGEOVER TIME OF THE VALVE SHOULD BE LESS THAN 60 SECONDS.

Charging water

1. Connect the water supply to a drain and fill valve.

2. Make sure the automatic air purge valve is open (at least 2 turns).

3. Fill with water until the water manometer indicates a pressure of approximately 2.0 bar.

Remove air in the circuit as much as possible using the air-purge valves. Air present in

the water circuit might cause malfunctioning of the optional backup heater.

4. Backup heater:

Check that the backup heater vessel is filled with water by opening the pressure relief

valve. Water must flow out of the valve.

NOTE

• During filling, it might not be possible to remove all the air in the system. Remaining air will be removed through the automatic air purge valves during first operating hours of the system. Additional filling with water afterwards might be required.

• The water pressure indicated on the water manometer will vary depending on the

water-temperature (higher pressure at higher water temperature).

• However, at all times water pressure should remain above 0.3 bar to avoid air

entering the circuit.

• The unit might dispose some excessive water through the pressure relief valve.

• Water quality must be according to EN directive 98/83 EC.
