How heat pumps work Heat metering Heat pumps operate on the same principle as a refrigerator: In addition to proof of the unit's efficiency, the EEWaermeG the same technology, only with reversed benefits. The (German law promoting renewable energy for heating) also refrigerator extracts heat from food, It discharges this heat requires heat metering (hereinafter referred to as WME).
Care of the unit CLEANING AND FLUSHING UNIT COMPONENTS You can use a damp cloth and standard cleaning products to CAUTION! clean the outer surfaces of the unit. Unit components may be cleaned and flushed only by customer service personnel Do not use cleaning or care products that contain abrasives, authorised by the manufacturer.
Scope of supply What to do first: Example of scope of supply packaging: Check the delivery for outwardly visible signs of damage… View 1: Check to make sure that the delivery is complete. Any defects or incorrect deliveries must be reported immediately. NOTE.
Installation and assembly NOTE. If several heat pumps of the same type are installed, only one heat pump must be considered. The following applies to all work to be done: If several heat pumps of different types are installed, the heat pump requiring the largest room or space NOTE.

Flush the heating circuit thoroughly before connecting the unit to the heating circuit… NOTE. Dirt and deposits in the heating circuit can cause malfunctions. Install shut-off devices for the heating water outlet (flow) and heating water inlet (return) on the heat pump side…...
Buffer tank CONDENSATE DRAIN The condensate precipitated from the air must be drained The hydraulic integration of the heat pump requires a buffer through the hose for condensate discharge provided on the tank in the heating circuit. It ensures a minimum running unit.
Electrical connection work Feed the 230 V power cable, power cable for circulation pumps and cable for outdoor temperature sensor through the rubber grommets in the facing panel… The following applies to all work to be done: • DANGER! Cut open the rubber grommets in the facing panel… Risk of fatal electric shock! All electrical connection work must be For details of the positioning of the rubber grom-...
has shown that the safest, most reliable and fault-free NOTE. running is achieved with so-called low-salt operation. The control unit of the heating and heat pump VDI 2035 Part I provides important information and rec- controller can be connected to a computer or ommendations regarding scaling and its prevention in heat- network using a suitable network cable, enabling ing and domestic hot water heating systems.
