Safety prec
To ensure safety, please be mindful of the following pr
WARNING
1. When installing or reloca ng the unit, be sure to keep the refrigerant circuit free from air or
substances other than the speci ed refrigerant. Any presence of air or other foreign substance in
the refrigerant circuit will cause system pressure rise or compressor rupture, resu 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 ed refrigerant. Otherwise, it may cause abnormal oper on, wrong
on, mechanical malfunc on or even series safety accident.
3. When refrigerant needs to be recovered during reloca 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 me for refrigerant recovery should not exceed 1 minute.
If refrigerant recovery takes too much me, air may be sucked in and cause pressure rise or
compressor rupture, resul 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 on pipe. If compressor starts running when stop valve is
open and connec on pipe is not yet connected, air will be sucked in and cause pressure rise or
compressor rupture, resul ng in injury.
5. When installing the unit, make sure that connec on pipe is securely connected before the
compressor starts running. If compressor starts running when stop valve is open and connec on
pipe is not yet connected, air will be sucked in and cause pressure rise or compressor rupture,
resul ng injury.
6. Prohibit installing the unit at the place where there may be leaked corrosive gas or 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 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 ons may
lead to electric shock o
8. Use the speci ed types of wires for electrical connec ons between the indoor and outdoor units.
Firmly clamp the wires so that their terminals receive not external stresses. Electric wires with
insu ient capacity, wrong wire connec ons and insecure wire terminals may cause electric shock
