• Check the water supply device and the release often. You should avoid the condition of no water or air
entering into the system as this will influence the unit's performance and reliability. You should clear the
pool/spa filter regularly to avoid damage to the unit as a result of a clogged filter.
• The area around the unit should be dry, clean and well ventilated. Clean the side heating exchanger regularly
to maintain good heat exchange and conserve energy.
• The operation pressure of the refrigerant system should only be serviced by a certified technician.
• Check the power supply and cable connection often. Should the unit begin to operate abnormally, switch it off
and contact your qualified technician.
• Discharge all water in the water pump and water system, so that freezing of the water-inlet the pump or water
system does not occur. You should discharge the water at the bottom of the water pump if the unit will not be
used for an extended period of time. You should check the unit thoroughly and fill the system with water fully
before using it for the first time after a prolonged period of no usage.
• Installation must be performed in accordance with the NEC/CEC by authorized person only.
