required.
DANGER - Failure to heed the following will result in injury or death.
WARNING Failure to heed the following may result in injury or death.
NOTICE Failure to heed the following may result in damage to equipment.
When installing and using your chiller basic safety precautions must always be followed, including the
following:
DANGER - Failure to heed the following will result in injury or death.
lThe chiller utilizes high voltage and rotating equipment. Use caution when
servicing.

Page - 2
WARNING Failure to heed the following may result in injury or death.
lInstallation and repairs must be performed by a qualified technician.
lThe chiller contains refrigerant under pressure. Repairs to the refrigerant circuit
must not be attempted by untrained and / or unqualified individuals. Service must
be performed only by qualified HVAC technicians. Recover refrigerant before
opening the system.
lImproper water chemistry can present a serious health hazard. To avoid possible
hazards, maintain pool / spa water per standards detailed in this document.
lProlonged immersion in water colder than normal body temperature may cause a
condition known as Hypothermia. The symptoms of Hypothermia include shivering
(although as hypothermia worsens, shivering stops), clumsiness or lack of
coordination, slurred speech or mumbling, confusion and poor decision-making,
drowsiness or low energy, lack of concern about personal welfare, progressive loss
of consciousness, weak pulse and slow or shallow breathing. In addition, persons
having an adverse medical history, or pregnant women, should consult a physician
before immersing in a cold body of water. Children and the elderly should be
supervised by a responsible adult.
NOTICE Failure to heed the following may result in damage to equipment.
lMaintain proper water chemistry in order to avoid damage to pump, filter, pool
shell, etc.
lWater flow exceeding maximum flow rate requires a bypass. Damage due to
excessive water flow will void warranty.
