Air-to-water heat pump in split design
LIA 7-9IM
LIA 12-16IM
Heat pump for heating with hydraulic unit (indoor) – and an outdoor unit, which are connected via a refrigerant pipe (special accessory).
The outdoor unit with an output-regulated compressor (inverter) adapts the heat output to the heat consumption of the building and
can be installed close to walls. The electrical connection between the indoor and outdoor units is via a 4-wire cable not included in the
scope of supply. The hydraulic unit contains the following components:
• Heat exchanger for connecting an unmixed heating circuit
• Circulating pump for heating and domestic hot water preparation
• Integrated pipe heater 3 kW (LIA 7-9IM)
• Integrated pipe heater 6 kW (LIA 12-16IM)
• Safety valve and expansion vessel 10 l
• Display with segment display
Simplified regulation for heating and domestic hot water preparation with external temperature-led heating regulation for mono energy
operation and definable time windows for domestic hot water preparation. Bivalent connection as return temperature lowering without
domestic hot water preparation. External, flow and return sensors integrated in the heat pump.
Lower operating limit heat source (heating operation) -20 °C ; Upper operating limit heat source (heating operation) 35 °C ;
Refrigerant R410A ; Connection heating ¾ ˝ ; Connection voltage 1/N/PE ~230 V, 50 Hz

It is absolutely essential that the commissioning of the split heat pump takes place via after-sales service (IN 30 WPS) owing to the cooling techno-
logy training required to connect the indoor and outdoor units. Dimplex split heat pumps feature a single-phase electrical connection (230 V).
They do not automatically meet the applicable technical connection conditions (TCC). Consent should therefore be obtained from the utility
company prior to connection. A utility block can be implemented via a contactor provided by the customer which disconnects all power to the
heat pump.
