Safety prec ĂƵƟ ons for installing and reloca Ɵ ng the unit
To ensure safety, please be mindful of the following pr ĞĐĂƵƟ ons.
WARNING
1. When installing or reloca Ɵ ng the unit, be sure to keep the refrigerant circuit free from air or
substances other than the speci Į ed refrigerant. Any presence of air or other foreign substance in
the refrigerant circuit will cause system pressure rise or compressor rupture, resu ůƟ ng in injury.
2. When installing or moving the unit, do not charge the refrigerant which is not comply with that on
the nameplate or unquali
Į ed refrigerant. Otherwise, it may cause abnormal oper ĂƟ on, wrong
ĂĐƟ on, mechanical malfunc Ɵ on or even series safety accident.
3. When refrigerant needs to be recovered during reloca Ɵ ng or repairing the unit, be sure that the
unit is running in cooling mode. Then, fully close the valve at high pressure side (liquid valve). About
30-40 seconds later, fully close the valve at low pressure side (gas valve), immediately stop the unit
and disconnect power. Please not that the
Ɵ me for refrigerant recovery should not exceed 1 minute.
If refrigerant recovery takes too much Ɵ me, air may be sucked in and cause pressure rise or
compressor rupture, resul
Ɵ
ng in injury.
4. During refrigerant recovery, make sure that liquid valve and gas valve are fully closed and power is
disconnected before detaching the connec
Ɵ on pipe. If compressor starts running when stop valve is
open and connec Ɵ on pipe is not yet connected, air will be sucked in and cause pressure rise or
compressor rupture, resul Ɵ ng in injury.
5. When installing the unit, make sure that connec Ɵ on pipe is securely connected before the
compressor starts running. If compressor starts running when stop valve is open and connec Ɵ on
pipe is not yet connected, air will be sucked in and cause pressure rise or compressor rupture,
resul
Ɵ ng injury.
6. Prohibit installing the unit at the place where there may be leaked corrosive gas or Ň ammable gas.
If there are leaked gasses around the unit, it may cause explosion and other accidents.
7. Do not use extension cords for electrical connec Ɵ ons. If the electric wire is not long enough, please
contact a local authorized service center and ask for a proper electric wire. Poor connec Ɵ ons may
lead to electric shock o ƌĮ re.
8. Use the speci Į ed types of wires for electrical connec Ɵ ons between the indoor and outdoor units.
Firmly clamp the wires so that their terminals receive not external stresses. Electric wires with
insu
ĸĐ ient capacity, wrong wire connec Ɵ ons and insecure wire terminals may cause electric shock
