1. Product safety statement 1. This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved.
2. Functionings & principles A low-pressure liquid refrigerant is vaporized in the heat pump's evaporator and passed into the compressor. As the pressure of the refrigerant increases, so does its temperature. The heated refrigerant runs through a condenser coil within the storage tank, transferring heat to the water stored there.

- Remove vent grid first. - Install diameter 160mm duct. - Pressure drops from duct must be lower than or equal to the static pressure of the fan. - If the pressure drops out of range, the performance of the appliance will be impaired. Maximum length of the air connection 5m (Diameter of air connection 160 mm).
Page 15
Habitable room or outside air (with two ducts): -Can obtain free heat from the garage. -If the outside air temperature is low, connection to the outside air may lead to overconsumption of electricity. -Referring installer menu, adjust the fan speed Installation caution When making the connections, you should respect the standards and local directives.

- If the mains pressure exceeds 80% of safety valve, a pressure reducer must be installed upstream of the appliance. Do not connect the domestic hot water connection directly to copper pipes in order to prevent galvanic couples in iron/copper (risk of corrosion). It is compulsory to fit the domestic hot water connection with a dielectricconnection (not supplied).

6. Operation and functions Display Functions: Electrical leakage protection The control system of this machine features an electricity leakage protection function. 10-minutes protection When starting the machine immediately after electricity input, the fan and the compressor will start at the same time. When starting the machine immediately after shutdown, the system goes into the protection mode and starts after 10 minutes, which is considered to be normal.
