TIMER SETTING

Before attempting to set the timer the time shall be set first.
Set the start of this working cycle by means of the key TIMER ON (green marked). Press the TIMER ON key and the time shown on the display will start
flashing. Press the TIMER ON key again and using the arrows ◄ and ► set the hour. Press the TIMER ON once more and set the minute in the same way.
Finally, confirm your selection by pressing the TIMER ON key.
Set the time of working cycle switch-off in similarly, but using the TIMER OFF key (red marked) for the purpose.
As soon as the timer is set, the heat pump will work in the day mode in compliance with the set times of the start and the end of its working cycle.
In case the same times are set for the start (ON) and the end (OFF) the cycle, the timer will not commence operation.
To cancel the timer operation press the TIMER ON and CLOCK keys in sequence (the green indicator light will go off) and then the TIMER OFF and
CLOCK in the same way (the red indicator light will go off, too).

CONTROL PANEL LOCKING

Press and hold pressed the keys SET and ◄ simultaneously for about 5 seconds. This operation will lock the control panel. Unlock the panel in the same way.

EQUIPMENT APPLICATION AND OPERATION

6.1

OPERATING INSTRUCTIONS

IMPORTANT:
In order the heat pump to heat the pool the filtration pump has to operate and water must flow through the heat exchanger.
Never switch the heat pump on if dry and the filtration system is not operating
Never cover the heat pump, as fresh ambient air must flow through it.
Protect the heat pump from frost. Before winter season drain all water from the filtration system and the heat pump and store them
for winter according to relevant instructions.
6.2

ADJUSTMENT OF OPERATING STATE USING BYPASS

In case a bypass line comprises a part of filtration circuit (it is not delivered as a part of heat pump supply), it may be used for setting the optimum operation
of heat pump after putting the latter in operation.
Bypass Use
The bypass line consists of three cock valves installed according to the figure below. On the right water comes from the filtration pump, while on the left it
flows through the return line back to the pool.
BACK TO
THE POOL
Close the cock valve 1 completely and open the cock VALVES 2 AND 3 on the inlet and outlet lines of the heat pump, respectively. At these conditions there is the maximum flow through
the heat pump. Put the heat pump into operation in the heating mode. Wait until the value of pressure read on the pressure gauge stabilizes. The correct pressure setting should be
within the range of 21 - 35 kg/cm (bar). If the pressure stabilizes below the value of 21 kg/cm

Routine adjustments of the three bypass valves:
COCK VALVE 1: Closed a bit so that the heat pump pressure gauge shows a pressure within the range from 21 to 35 kg/cm
COCK VALVE 2: Open.
COCK VALVE 3: Half closed.

WATER CONDENSATION

Lower temperatures of the evaporator during the heat pump operation are the cause of air moisture condensation on evaporator lamellae and condensate formation.
If the relative air humidity is very high, as much as a few litres per hour can be produced. This water will flow down over the lamellae into the space of cabinet bottom
and drains away through a plastic fitting designed for connection to a 3/4" PVC draining hose directing the condensate to a suitable sewer system.
It is very simple to mix up the condensed water with water leaked from heat pump inside. There are two simple methods how one can find whether the liquid is the condensate or not:
1. Switch the equipment off and leave the pool pump in operation only. If the water stops flowing out, the condensate is concerned.
2. Make the test for the presence of chlorine in the water in question (provided that chlorine is used for pool water treatment) - condensate should not contain chlorine.
Note: Moisture that can be present near the equipment results from water vapour condensation and is quite OK.
6.4

AUTOMATIC DEFROSTING OF EVAPORATOR

The evaporator has to be defrosted in the heating mode only, as the evaporator lamellae can get iced up by condensate if ambient temperatures are too
low. The process runs automatically according to parameters set for the defrosting mode, see chapter 5.3 Operating Parameter Setting and Checking.
The following process refers to setting the parameters 3, 4, 5 a 6.
Course of Defrosting:
1 – Process start:
The defrosting system will switch-on, if the following conditions are met at the same time:
- The temperature measured by the temperature sensor of defrosting drops below -5 °C (the measurement is made in each 40 minutes of operation).
- The compressor runs for 40 minutes continuously, without interruption.
2 – Both the compressor and blower are stopped.
3 – After the delay of approx. 20 second the four-way valve is reconfigured.
4 – One minute after stopping (only) the compressor starts and the frost deposit accumulated on the lamellar evaporator
begins to thaw out which is usually associated with vapour formation.
5 – Process end:
Defrosting is finished as soon as either of the following conditions is met:
- The temperature of the temperature sensor rises to 15 °C.
- The compressor runs for the total time of 6 minutes only.
6 – The compressor stops.
7 – One minute (approx.) after it has stopped the four-way valve is reconfigured.
8 – Within two minutes of stopping the compressor starts again together with the blower in the heating mode.
6.5

FORCED DEFROSTING

In case that frost begins to deposit on the evaporator one can make use of the forced defrosting function.
Press and hold pressed the key MODE for about 10 seconds. The equipment will start defrosting the evaporator. The mode of forced defrosting will terminate
as soon as the set defrosting parameters are achieved. Then the equipment will stop for a minute (approx.) and resumes operation in its normal heating mode.
Note: The defrosting parameters can be set – for details see chapter 5.2 Operating Parameter Setting.
Note: Neither automatic nor forced defrosting can be used in case the heat pump operates in the cooling mode.
DANGER: Use the mode of forced defrosting only if there is a real frost deposit on the evaporator.
The application of forced defrosting in other events may result in equipment overheating, coolant leakage
or even damage to the equipment.
6.6

POSSIBLE PROBLEMS DUE TO EXTERNAL CONDITIONS

Under certain external conditions the exchange of heat may be insufficient between coolant and water on one side and coolant and air on the other side. It results in
a pressure increase in the cooling circuit and increased power consumption of the compressor. The temperature sensor fixed at compressor discharge line and the circuit
breaker in the supply line will protect the equipment from such extreme conditions. The display will show the error message EE 6.
