Pipe connection and air purging *
* The following pipe connection and air purging instructions are only suitable
for air conditioner models other than quick coupler models. Instructions for
quick coupler models follow on page 13.
The air conditioning system must be installed in way that ensures that no
dust, foreign articles, air or moisture can enter the system. Pay particular
attention when connecting the pipes for the outdoor unit.
• Try to avoid repeated curves as much as possible, otherwise the copper
pipes may harden or crack.
• Use suitable wrenches for connecting the pipes so as to ensure appropriate
torque. Refer to the torque table below for torque values (Table 1).
Excessive torque might damage the joints while too little torque might lead
to leakage.
