operation, please unplug the unit and plug it back in after 1 hour.
Note: Please contact technical support when the failures cannot be solved.
Check the water supply device and the trigger often. You should prevent water or
ο
air from entering the system, as this will affect the performance and reliability of
the device. You must clean the pool/spa filter regularly to avoid damage to the
unit due to a clogged or dirty filter.The area around the unit should be dry, clean
and well ventilated. Clean the side heat exchanger regularly to maintain good
heat exchange and save energy.
The operating pressure of the refrigerant system should only be maintained by a
ο
certified technician.
Check the power supply and cable connections regularly. If the unit starts to
ο
operate abnormally, turn it off and contact a qualified technician.
Discharge all water from the water pump and water system, so that the water in
ο
the pump or water system does not freeze. You must drain the water at the
bottom of the water pump if the unit is not used for an extended period of time.
You must check the unit carefully and fill the water system before using it for the
first time.
Checks in the area
ο
Prior to beginning work on systems containing flammable refrigerants, safety
ο
checks are required to ensure that the risk of ignition is minimized. The following
precautions should be observed before work is performed on the refrigeration
system. Extended period of non-use.
Work
ο
All work shall be undertaken under a controlled procedure so as to minimize the
risk of flammable gases or vapors being present during the performance of the
work.
General Work Area
ο
All maintenance personnel and others working in the local area shall be informed of
the nature of the work being performed. Work in confined spaces should be avoided.
The area around the work space should be isolated. Care should be taken to ensure
that conditions in the area have been made safe by controlling flammable materials.
Check for the presence of refrigerant
ο
The area should be checked with an appropriate refrigerant detector before and
during work to ensure that the technician is aware of potentially flammable
atmospheres. Care should be taken to ensure that the leak detection equipment used
is suitable for use with flammable refrigerants, i.e., non-sparking, properly sealed or
intrinsically safe.
Presence of a fire extinguisher
ο
If hot work is to be performed on refrigeration equipment or any associated parts,
appropriate fire extinguishing equipment must be available. Have a dry powder or
CO2 fire extinguisher available near the loading area.
No source of ignition
