HEAT PUMP MICROW ELL HP
1. INTRODUCTION
In your hands you hold probably the most advanced and the most efficient heat pump currently
available on the market. This heat pump p rovides warm water in your pool at lowest possible cost.
The heat pump is manufactured in tightest accordance with related strict standards and norms, in
order to provide high quality operatio n and long-term reliability.
This Installation and user manual contains all the necessary information about the installation,
operation and maintenance of the heat pump. Please read this Installation and user ma nual carefully
before you start to use this product. The m anufa cturer is not responsible for any p ersonal or property
damage due to the improper installation, use or maintenance that is not in acco rdance with t his User
Manual.
This Installation and user manual is an inseparable p art of this product; therefore it must be kept in
good condition and must accompany the heat pump.
1.1 Product description
The heat pump is designed exclusi vely for swimm ing pool wa ter heating or cooling and maintaining its
temperature on the requested level. Other appropriate application is water temperature conditio ning
for fish tanks, wine ciders or horse cooling facilities. These applications should be discussed with local
installer or distributor. Any other form of application is considered inappropriate.
The heat pump achieves the highest efficiency at 15÷35°C air temperature. At ambient air
temperatures lo wer than -5°C the ef ficiency of the device decreases and at the temperatures higher
than +40°C the heat pump can get overheated which may result in its malfunction, damage or failure.
Do not use the prod uct out of the designated operational air temperature range which is stated
in
section 3.1 Technical data
.
This heat pump is designed for swimming pools with up to 40 m
3
- HP 1100 and up to 60 m3 - HP
1500 of pool water volume . For proper operations there must be water flow through the ex change r of
the heat pump (within water filtration circuit) in the range of 4-6 m
3
/h.
The heat pump enables heat gain from the external air surrounding the swimming pool t hrough the
compression – expansion cycles of the heat-carrying liquid. The air is driven by a fan through the
evaporator where it will deliver it s heat to the heat -carrying liquid (the air is being cooled at the sam e
time). The heat-carrying liquid is then delivered to t he spirals of the exchanger by the compress or
which pressurises it and thus he ats it up. In these spirals, the hea t-carrying liquid delivers its heat to
the swimming pool water. From the exchanger there is a cooled liquid flowing to the expansion valve
or capillary where its pressure decreases and it gets cooled down rapidly at the same time. This
cooled liquid flows to the evaporator again where it gets heated by the flowing air. The whole process
runs fully automatically and is monitored by the pressure and temperature sensors. The same
principle is applied when heat pump operates in cooling mode.
Using simple language, a heat pump is able to extract the heat/cold that is present in ambient
environment and leveraged pass it into the pool water. When heating, higher the ambient air
temperature is, more free energy can the heat pump extract and thus reach higher efficiency. At
favourable conditions you pay around 15% of heat, i.e. 85% of heat is free. Please review below
drawing of different ambient air conditions with subsequent efficiencies.
The heat pump efficiency grows by the increasing surrounding air temperature.
It takes some days to achieve the requested swimming pool water temperature. This time period
depends on heat loss and heat gain ba lance of your pool.
Example factors of heat losses: poor pool construction, used materials, usage of cover, air – water
temperature relationship, fresh water refilling, filtra tion, etc.
Example factors of heat gains: intensity of sun, winds, orientation of pool, air – water temperature
relationship, etc.
In order to avoid heat loss when the swimming pool is not being used, it is highly advised to use
pool’s cover.

HEAT PUMP MICROWEL L HP
Ideal water temperature for external pools is considered at levels from 27° to 32°C. This may change
based on particular demands of the user. When setting the desired air temperature higher than 32°C
please review the material characteristics of your pool parts. High water temperature can damage
these materials a nd contrib ute to creation of algea. Manufa cturer, distributor and reseller do not bear
responsibility resulting from inappropriate heat pump usage.

3.5 Security and control systems
In order to ensure long term reliability and fully automatic operations of the heat pump, the pump is
pump is equipped with following security systems:
Temperature based control of the heat pump operation:
The heat sensor placed on t he heat exchange r, ensures sw itching off of the heat pump when
the requested water temperature is reached. The normal operating mode gets renewed if the
water temperature in the exchanger drops by 3 °C (manufacturing setting) below the
requested value.
Safety systems:
Water flow sensor (flow switch) placed on the water heat e xchanger inlet.
The water flow sens or switches on the hea t pump when there is wate r flowing through the
heat pump exchanger, and switches it off when the water flow stops or is too high or low.
Sensor of the minimal and maximal gas pressure in the refrigerant circuit.
Heat sensor on the refrigerant outlet from the compressor.
Time protection
The unit is equipped with a switching time delaying device with a preset 3 minutes delay
period for protecting the control elements in the circuit and eliminating repeated restarts and
contactor vibrations. This time delay will automatically restart the unit app. 3 minutes after
every single interruption of t he heat pum p operati on. Even if there i s only a sh ort inte rruption
of the power supply, the time protection will get activated so the unit cannot start the
operation earlier t han the pressure s in the refrigerant circ uit of the heat p ump get balanced.
Interruption of the power supply during the pause time does not influence t he time interval.
Antifreeze protection
If an ambient air temperature is low (e.g. below 7°C), it is normal to have ice creations on the
evaporator of your heat pump. This is freezing condensated water. Your heat pump is
equipped with automatic defrosting.
Manufacturer has preset the conditions when automatic defrosting gets activated in order to
ensure optimal operations and performance of the heat pump. For more information please
refer to section 5.7 Setting of the operating parameters
and
section 7.2 Defrosting
.
If your heat pump freezes up on often basis it is advised to reconsider the efficiency of heat
pump running (heating) in such conditions.
If a failure occurs to any of above systems there will be an error message shown on the display
starting with ‘EE’. Please check
section
7.5
Failure reports
of this Installation and user manual.
Warning:
Elimination or disabling from operation any of the control or security systems results in
warranty void.
