Page 31: Water Pipe Work
Water pipe-work Checking the water circuit The 3-way valve is built-in the unit. So the unit is equipped with the water inlet/outlet for hot water connection, and the water inlet/outlet for space heating/cooling. The water circuits must be provided by a licensed technician and must comply with all relevant European and national regulations. -
Page 32: Checking The Water Volume And Expansion Vessel Pre-Pressure
Checking the water volume and expansion vessel pre-pressure The unit is equipped with an expansion vessel of 10 liters which has a default pre-pressure of 1 bar. To assure proper operation of the unit, the pre-pressure of the expansion vessel might need to be adjusted and the minimum and maximum water volume must be checked. -
Page 33: Setting The Pre-Pressure Of The Expansion Vessel
Setting the pre-pressure of the expansion vessel When it is required to change the default pre-pressure of the expansion vessel (1 bar), keep in mind the following guidelines: Use only dry nitrogen to set the expansion vessel pre-pressure. Inappropriate setting of the expansion vessel pre-pressure will lead to possible malfunctioning of the system. -
Page 34: Charging Water
THE UNIT IS ONLY TO BE USED IN A CLOSED WATER SYSTEM. APPLICATION IN AN OPEN WATER CIRCUIT CAN LEAD TO EXCESSIVE CORROSION OF THE WATER PIPING. NEVER USE ZN-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. -

Page 39: Pre-Operation Checks
Pre-operation checks Checks before initial start-up SWITCH OFF THE POWER SUPPLY BEFORE MAKING ANY CONNECTIONS. After the installation of the unit, check the following before switching on the circuit breaker: 1. Field wiring Make sure that the field wiring between the local supply panel and domestic hot water tank has been carried out according to the instructions, according to the wiring diagrams and according to European and national regulations. -
Page 40: Setting The Pump Speed
Setting the pump speed The pump speed can be selected on the pump. The default setting is high speed (III). If the water flow in the system is too high (e.g., noise of running water in the installation) the speed can be lowered (I or II). The available external static pressure (ESP, expressed in mH2O) in function of the water flow (l/min) is shown in the graph below. -
Page 41: Maintenance
MAINTENANCE In order to ensure optimal availability of the unit, a number of checks and inspections on the unit and the field wiring have to be carried out at regular intervals. BEFORE CARRYING OUT ANY MAINTENANCE OR REPAIR ACTIVITY, ALWAYS SWITCH ‘OFF’ THE CIRCUIT BREAKER ON THE SUPPLY PANEL, REMOVE THE FUSES OR OPEN THE PROTECTION DEVICES OF THE UNIT. -
