the gas (large) pipe;
When the vertical pipe height difference is more than 5 meters, then for every 5 meters an oil loop must be
installed at the bottom of the gas (large) pipe, and a short loop (liquid ring) should be installed at the exit of the
indoor unit liquid (small) pipe;
When the connecting gas pipe vertical height difference is less than 5 meters but the constant rise distance is
too long, an oil loop should be installed in the gas (large) pipe every 10 meters.
◇
When the outdoor and indoor units are at the same elevation, the oil deposit bend and liquid ring do not need
to be installed, if the horizontal connecting pipe length is less than 10 meters.
When the horizontal connecting pipe length is more than 10 metres, install an oil loop in the gas (large) pipe
every 10 metres.
Note:
This chart is for explanation purposes. An actual installation will differ from this according to the site conditions.
When making an oil trap the radius of the bend should be between 1.5 and 2 times the pipe diameter.
7.3. Electrical connection
7.3.1Electrical connection precaution
Warning
Installation of electric items must be carried out by qualified, professional technicians. An isolated circuitry
should be fixed with whole-pole disconnection devices, which is with at least 3mm gap of touch point. .
Power supply and indoor to outdoor connection should use special cable. Providing the necessity of
installation or replacement, the professional technician of service store appointed by manufacturer must
be required, while self-operation by users is prohibited.
In case of any electric shock accident, the creepage protection devices /power supply on-off and breaker
must be required with power supply.
The specification of fuse for single phase control board is F5AL 250V, while for 3 phase control board,
both indoor and outdoor unit, it is F3.15AL 250V
。
Machine must be earthed surely. If not, it’ll be probably caused creepage.
Equivalent 227IEC53(RVV) type of power cord of GB5023 or the excelled must be required. The cords
should be fixed properly against broken, while ends/joints of cords is under outside force. Improper
connection or fixation will cause disaster like fire….etc. Equivalent 245IEC57(YZW) type of power cord of
GB5023 or the excelled must be used as connection line of indoor and outdoor.
