INTRODUCTION
In your hands you hold probably the most advanced and the most efficient heat pump currently
available on the market. This heat pump provides 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 operation 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 manual carefully
before you start to use this product. The manufacturer is not responsible for any personal or property
damage due to the improper installation, use or maintenance that is not in accordance with this User
Manual.
This Installation and user manual is an inseparable part 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 exclusively for swimming pool water heating or cooling and maintaining its
temperature on the requested level. Other appropriate application is water temperature conditioning
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 lower than -5°C the efficiency 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 product 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 70 m
3
- HP 1700 of pool water volume. For
proper operations there must be water flow through the exchanger of the heat pump (within water
filtration circuit) in the range of 686 m
3
/h.
The heat pump enables heat gain from the external air surrounding the swimming pool through the
compression – expansion cycles of the heat-carrying liquid. The air is driven by a fan through the
evaporator where it will deliver its heat to the heat-carrying liquid (the air is being cooled at the same
time). The heat-carrying liquid is then delivered to the spirals of the exchanger by the compressor
which pressurises it and thus heats it up. In these spirals, the heat-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 balance of your pool.
Example factors of heat losses: poor pool construction, used materials, usage of cover, air – water
temperature relationship, fresh water refilling, filtration, 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.
