5. MAINTENANCE AND INSPECTION

5.1 Maintenanc e
Check the wate r suppl y device and th e release often. You shoul d avoi d the conditio n of no water or air enterin g
into system, as this will influenc e unit' s performanc e and reliabilit y. You shoul d clear the pool/sp a filte r regularl y
t o avoi d damag e t o the unit as a result of dirt y or clogge d filte r.
The area around the uni t shoul d b e dr y, clean and well ventilated . Clean th e side heatin g exchanger
regularl y t o maintai n good heat exchange and conserv e energ y .
The operatio n pressure of th e refrigeran t system should only b e serviced b y a certifie d technician .
Check th e power supply and cable connectio n often,.Should the uni t begin to operate abnormall y,
switch it off and contac t th e qualifie d technician .
Discharge all water in the water pump and water system, so that freezing of the water
in the pump or water system does not occur. You should discharge the water at the bottom
of 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.
