2. Safety Instructions
This manual provides you with the information necessary for optimal use and maintenance.
Please read this manual carefully before installation and use and keep it for future reference.
Please noted the following :
1 Do not turn the machine upside down or tilt it. If the machine is tilted or sideways, stand the
machine upright for 24 hours before starting the heat pump.
2 The machine must be installed on a flat and strong bottom surface, otherwise it may fall or
shift during operation, resulting in accidents.
3
.
.
. Do not drop or hit the machine, otherwise it may cause damage to the machine, prevent
normal use, and may even cause personal injury or property damage.
The machine must be installed outdoors, or the noise and condensation generated by the 4.
machine may cause some inconvenience. However, some parts of the machine must be
protected from rain and water. For example, the power plug should be installed indoors.
Do not supply power to the machine through a transformer, please make sure that the local 5.
power supply voltage matches the power supply voltage required by the machine, otherwise
a dangerous situation may occur.
Do not pull the power plug forcibly. Do not run the power cord around the machine during 6.
operation.
If the heat pump is damaged during transportation, it must be replaced, please contact your 7.
service center or similar qualified personnel to avoid danger.
Before starting to use the machine, make sure that the water connection of the machine is 8.
properly connected and fixed to ensure the normal operation of the machine and avoid leakage.
9 When the machine is running, do not insert objects directly into the air outlet, otherwise it
will cause blockage and damage of the fan, and may even cause human injury.
10
.
. The evaporator fins of the machine are quite sharp, please do not touch them, otherwise it
may cause human injury.
Do not damage the fins of the evaporator, so as not to affect the efficiency of the machine.11
12
.
. This machine is not suitable for persons with reduced physical, sensory or mental abilities
01

or lack of experience and knowledge, including installation, use, etc., unless its use is
supervised or instructed by personnel responsible for its safety.
This machine is forbidden for children to use alone. The guardian should supervise the child13.
away from the machine to ensure safety.
The efficiency of the machine will decrease when the ambient temperature is low, and it 14.
cannot be used normally when the temperature is below 5 ° C.
Before not using the machine and cleaning, please unplug the power plug from the socket, 15.
otherwise it may cause accidents.
The heat exchanger of PVC material is used inside the machine. Excessive water entering 16.
the machine may cause damage to the heat exchanger and leak water. Therefore, the maximum
water temperature should not exceed 35 ° C. When the water temperature is higher than 35 ° C,
please do not let water enter the machine.

4. Instructions Guide
4.1 Components
Before the machine is installed, the following components need to be
configured to complete the installation:
1. Circulating water pump: 1 set, providing water circulation power between the machine and
the swimming pool.
2. Swimming pool: 1
3. Power supply equipment: 1 set, providing power for the machine and water pump
4. Water treatment equipment
5. Connect water pipes and fixtures
4.2 Installation requirements
1. The distance between the machine and the swimming pool should not be less than 2 meters.
2. The water treatment system should be installed on the pipeline at the water outlet of the
machine to avoid direct damage to the internal components of the machine from chemicals.
3. During operation, especially when used in a high humidity environment, the machine will
generate condensed water. Ensure that the drainage around the machine is smooth.

If the water quality exceeds the data range of the above table, it may cause irreversible
damage to the machine. If the machine is damaged as a result, the corresponding warranty
terms are invalid.
5.2 Use in harsh climates
1. This machine can be used for running in rainy conditions, but should not be immersed in
water. Failure to do so may cause damage, even leakage of electricity, resulting in personal
injury and property damage.
2. When the machine is in a low environment, the work efficiency is low. It is generally
recommended not to use the machine below 5 ° C. Drain the machine and the pool water
at the same time, place the machine in a dry place and take protective measures.
5.3 Reuse
If your machine has been stored for a long time, please check the following steps when reusing
it:
Inspect the system for debris or housing damage.
Clean the evaporator fins if necessary. Make sure that the evaporator heat sink is clean, so
1.
2.
that blocking the intake air will cause insufficient operation and reduce machine efficiency.
Check if the fan is blocked.
Check whether there are foreign objects in the water inlet and outlet.
Connect the water inlet and outlet, turn on the pool water circulation pump, and start

7. Maintenance and repair
7.1 Daily maintenance
1. When using, check the water supply to and from the machine frequently. Low water flow or
.
air should be prevented from entering the pipeline, which will reduce the performance and
reliability of the machine and may even cause the machine to malfunction.
2 The swimming pool water should be washed regularly to avoid damage to the heat pump
due to the dirty water in the swimming pool.The resulting damage is not covered by the
warranty.
10

3. The area around the machine should be clean and well ventilated. The evaporator and the
evaporator shield should be cleaned regularly to maintain good air flow and ensure that the
machine has high operating efficiency.
4. Check the power and cable connections frequently. If there is abnormal operation or a
burning odor near the electrical room, please turn off the machine and contact a professional
technician for maintenance.
5. If the water heater does not work for a long time, the water inside the machine should be
drained.
