Page 22: 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 23: 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 24: 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. -
