Security cautions
Warnings and cautions
Warnings are provided to alert installing contractors about potential hazards that could result in personal
injury or death,
while cautions are designed to alert personnel about conditions that could result in
minor injury and equipment damage.
Your personal safety and the proper operation of this machine depend upon the strict observance of
these precautions.
WARNING
1. The installation should correspond to the distributor or to another authorized professional. Inappropriate
installation could provoke water leaks, electric shock or fire.
2. Install the unit following instrucctions contained in this manual. An incomplete installation could provoke
water leaks, electric shock or fire.
3. Verify that parts used in the installation are those provided or specified. The use of other parts could
perhaps not adjust appropriately and lead to water leaks, electric shock or fire.
4. Install the unit on a solid base capable of supporting the weight of same. Should the unit fall due to
inadequate supporting base or incomplete installation, it could lead to personal injury or property damage.
5. Electrical installation should conform to the installation manual and the appropriate NEC codes and local/
state codes. Insufficient capacity or incomplete electrical installation could lead to electric shock or fire.
6. Ascertain the use of an independent power source. Never use a power source that is shared with another
piece of equipment or device.
7. For wiring, use wiring of sufficient length to reach the required distance withouth the need of splicing. Do
not use extension cables. Do not add additional charges to the power supply. Employ an independent power
circuit. (If these instructions are not followed, it could cause abnormal overheating, electric shock or fire.)
8. Use the specified types of wiring for electrical connectrions between the indoor and outdoor units. Properly
adjust the interconnecting cables in order to avoid external stress upon their terminal box. Incomplete
connection or adjustment jobs could cause overheating of the junction box and provoke fire.
9. When ending the tasks of interconnection and power supply wiring, place the wiring appropriately to avoid
unwanted pressure over the electric panels and covers. Install all corresponding panels over the wiring.
Incomplete installation could cause overheating of the junction box, electric shock or fire.
10. Once the installation has ended, verify the absence of refrigerant leaks.
11. If a refrigerant leak has been detected during the installaton process, ventilate the room. (Refrigerant
produces a toxic gas if it were to be exposed to flames).
12. During the pumpdown process, stop the compressor before removing the refrigerant lines. If the
compressor continues to run and the stop valve is in open position during pumpdown, air will be
suctioned during the removal of the refrigerant lines, producing abnormal pressure on the refrigerant
cycle, which in turn could lead to breakage and personal injury.
