Installation and Maintenance
1. Select the installation location according to the require-
ment of this manual.(See the requirements in installation
part)
2. Handle unit transportation with care; the unit should not
be carried by only one person if it is more than 20kg.
3. When installing the indoor unit and outdoor unit, a suffi
-
cient fixing bolt must be installed; make sure the installation
support is firm.
4. Ware safety belt if the height of working is above 2m.
5. Use equipped components or appointed components dur-
ing installation.
6. Make sure no foreign objects are left in the unit after fin
-
ishing installation.
1. Avoid contact between refrigerant and fire as it generates
poisonous gas; Prohibit prolong the connection pipe by
welding.
2. Apply specified refrigerant only. Never have it mixed with
any other refrigerant. Never have air remain in the refrigerant
line as it may lead to rupture or other hazards.
3. Make sure no refrigerant gas is leaking out when
installation is completed.
4. If there is refrigerant leakage, please take sufficient
measure to minimize the density of refrigerant.
5. Never touch the refrigerant piping or compressor without
wearing glove to avoid scald or frostbite.
Refrigerant Safety Precautions:
Improper installation may lead to fire hazard, explosion,
electric shock or injury.
Installation Safety Precautions:
connection pipe is not yet connected, air will be sucked in
and cause pressure rise or compressor rupture, resulting in
injury.
●Prohibit installing the unit at the place where there may be
leaked corrosive gas or flammable gas.
If there leaked gas around the unit, it may cause explosion
and other accidents.
●Do not use extension cords for electrical connections. If
the electric wire
is not long enough, please contact a local service center
authorized and ask for a proper electric wire.
Poor connections may lead to electric shock or fire.
●Use the specified types of wires for electrical connections
between the indoor and outdoor units. Firmly clamp the
wires so that their terminals receive no external stresses.
Electric wires with insufficient capacity, wrong wire
connections and insecure wire terminals may cause electric
shock or fire.
