3.4 Winter storage
Winter storage is essential due to the risk of the condenser freezing and breaking. This situation is not
covered by the warranty.
To avoid damaging the device with condensation, do not cover it with an air‐tight cover.
 switch the digital control panel to "stand‐by" mode by pressing
 open valve 1,
 close valves 2 and 3, and open valves 4 and 5 (if fitted),
 ensure that no water is flowing through the heat pump,
 drain the water condenser by unscrewing the two pool water inlet and outlet connections at the back of the
heat pump,
 in the case of full winter storage conditions for the pool: re‐connect the inlet and outlet connections to avoid
foreign bodies entering into the condenser,
 in the case of winter storage for the heat pump alone: do not reconnect the inlet and outlet connectors, instead
place two plugs (supplied) on the condenser water inlet and outlet.
 cover the heat pump with a micro‐breathing overwintering cover (optional accessory, see §4.3).
4. Maintenance
4.1 Maintenance instructions
It is recommended that the device be general serviced on a yearly basis to ensure proper operation,
maintain performance levels and prevent some potential failures.
This is the responsibility of the user and must be performed by a qualified technician.
Do not use a high‐pressure water hose.
 ensure no foreign bodies obstruct the fan grid.
 clean the evaporator with a soft brush and a fresh water jet (disconnect the power cable), do not twist or bend
the metal blades, then to clean the discharge pipe of the condensates in order to evacuate the impurities which
could block it,
 clean the outside of the unit with a solvent‐free product. A specific PAC NET cleaning kit is available as an
optional extra (see §4.3),
 check that the water condensation flows out properly during the operation of the device.
 check the proper operation of the regulator,
 check electrical components,
 check that all metal elements are grounded,
 check the tightening and connections of electric cables and the cleanliness of the electrical compartment.
4.2 Additional recommendations
in relation to the Pressure Equipment Directive (PED‐97/23/CE)
4.2.1 Installation and maintenance
 the unit may not be installed close to combustible materials, or the air duct inlet of an adjacent building .
 with some devices, it is essential to fit protection grids if the unit is installed in an area with uncontrolled access.
 during installation, troubleshooting and maintenance, pipes may not be used as steps: the pipe could break
under the weight, spilling refrigerant and possibly causing serious burns.
 when servicing the appliance, the composition and state of heat carrying fluid must be checked, as well as the
absence of any refrigerant.
 during the annual unit sealing test in accordance with applicable legislation, the high and low pressure switches
must be checked to ensure that they are securely fastened to the coolant circuit and that they cutoff the
electrical circuit when tripped.
 during maintenance work, ensure there are no traces of corrosion or oil around cooling components.
 before beginning work on the cooling circuit, stop the device and wait for a few minutes before fitting the
temperature and pressure sensors. Some elements such as the compressor and piping may reach temperatures
in excess of 100°C and high pressures with the consequent risk of severe scalding.
