The connection pipe should be insulated with proper water-proof insulating material.
The pipe wall thickness shall be 0.5~1.0mm (1/50~1/25inch) and the pipe wall shall be able to
withstand the pressure of 6.0MPa (870psig). The longer the connecting pipe, the lower the cooling and
heating effect performs.
4 ELECTRIC WIRING WORK
4.1 Wiring Precautions
①. Before obtaining access to terminals, all supply circuits must be disconnected.
②. The rated voltage of the unit is as shown as Table 1-4-1 and Table 1-4-2
③. Before turning on, verify that the voltage is within the 187~252V range (for single phrase units).
④. Always use a special branch circuit and install a special receptacle to supply power to the air conditioner.
⑤. Use a special branch circuit breaker and receptacle matched to the capacity of the air conditioner.
⑥. The special branch circuit breaker is installed in the permanent wiring. Always use a circuit that can trip all the poles
of the wiring and has an isolation distance of at least 3mm (1/8inch) between the contacts of each pole.
