This state is due to the following causes:
HEATING MODE
Insufficient water flow rate. Close the bypass
valve to increase heat transfer from water to water
Note: This error message will be most possibly displayed when the temperatures both of pool water and of ambient air are high.

REMARKS ON HEAT PUMP OPERATION
Heat pump efficiency will increase with the increasing temperature of ambient air.
The achievement of required pool water temperature may take a few days. This time is quite normal and depends particularly on climatic
conditions, the volume of pool water, size of water surface area, time of heating pump operation and pool heat loss (caused by evaporation, heat
transfer through pool walls, radiation, etc.). Failing to take measures to limit the heat loss, it will not be economical, or even possible, to maintain
any higher temperature of pool water.
To limit the heat loss at the time in which the pool is out of use, a cover or solar blanket can be used.
The temperature of pool water should not exceed 30 °C. Warm water has not any refreshing effect and, moreover, creates favourable conditions for
microbial growth (of algae, etc.). In addition, certain pool components may have temperature limits, for instance the foils of foil pools can get soft
and lose their firm shape. Do not set any higher temperature than 30 °C on your thermostat.

COOLING MODE
Too high water flow rate. Open the bypass valve to reduce
water flow rate and increase thereby the heat transfer
from water to coolant.
Insufficient flow of air. Make sure that evaporator
lamellae are not fouled.

MAINTENANCE AND INSPECTION
7.1
MAINTENANCE
CAUTION: The equipment includes live electrical components. Only an electrician of adequate technical
qualification may open the housing. There is a risk of electrical accident!
IMPORTANT: Before any attempt to make intervention into the equipment make sure it is fully disconnected
from its power supply.
(a) Clean regularly both the pool and the filtration unit to protect the equipment from damage due to fouled or clogged filter.
(b) Inspect regularly the power supply system, the condition of the supply cable in particular. In case the equipment begins to show operational irregularities,
switch it off immediately and contact an authorised service centre.
(c) Check regularly the working area of heat pump (see the figure in chapter 4.1 Site Selection) and keep it clean and free of debris, dead leaves or snow.
(d) If the heat pump is not used, disconnect it from the mains, drain it and cover it with an impermeable tarpaulin or PE foil.
(e) Wash the heat pump exterior with clean water and an ordinary kitchenware cleaning agent.
(f) Using a soft brush clean regularly the outer surfaces of evaporator and keep it free of any stuck dirt. The lamellae can be carefully cleaned using a flat,
not sharp tool. The guarantee shall not apply to any mechanical damage to the lamellae.
(g) Check regularly the tightness of screws (bolts) anchoring the equipment to the support and the screws fixing the covers. Check the supply cable
for damage and wear. Clean any rusted parts with a wire brush and treat them with corrosion resistant coating.
(h) Regularly remove the top cover and clean the heat pump from dirt.
(i) Any repair shall be carried out by a duly qualified technician.
(j) Any maintenance work of the cooling system shall be carried out by a duly qualified technician.
7.2
WINTERING
(a) Disconnect the heat pump from the mains.
(b) Close the bypass cock valves nos. 2 and 3 (see the figure in chapter 6.2 Adjustment of Operating State Using Bypass).
(c) Drain all water from the heat pump by disconnecting the pipe system from both connections of the filtration circuit (THERE IS A RISK OF FREEZING).
(d) Suck all residual water from the evaporator to leave it dry (THERE IS A RISK OF FREEZING).
(e) Reconnect the filtration circuit (do not tighten its connections) to protect the heat pump against ingress of dirt or water.
IMPORTANT: Correct wintering is very important. No water can be left in the heat exchanger. The guarantee
shall not apply to any exchanger damage caused by frost.
