• As shown in the figure above, the pipe can be removed from the front, the right, the bottom and the back.
• When connecting pipes on site, use a wrench to sever the semi-finished through hole on the outer plate (ø88mm
or ø100mm).
• Please use a stopper (provided on site) to plug the pipe outlet in order to prevent entry of small animals, etc.
• Please connect pipe and operating valve with corner joints (provided on site).
• As shown in the figure below, when fixing pipe on site, please set pipe fixing position more than 1.5 m distant
from outdoor unit. (Otherwise, pipe may be broken sometimes due to various anti-vibration methods).

(2) Pipe Construction
Important notes
• Prevent collision between pipe under construction and components inside unit.
• When conducting pipe construction on site, please turn off operating valve completely.
• It is necessary to protect pipe ends (by welding them after squashing or by wrapping them tightly with tape), to
prevent entry of moisture and foreign substances.
• Try to bend pipe around a large radius (more than four times the pipe diameter). Do not repeat bending.
• Use bell mouth to connect outdoor unit liquid pipe and liquid refrigerant pipe. Please install flared nut on the pipe
to conduct flaring. The flaring method for R410A differs from the previous one for R407C. Flaring tool for R410A
is appropriative, but the previous tools will be still available if copper pipe gauge for adjustment of exposed
length is used to adjust exposed length B.
• Ester oil is proposed as flaring oil so as to adapt to unit type of R410A refrigerant.
• During connection for pipe flaring, please tighten the pipe with double wrenches. Refer to the following values
for tightening torque of the flared nut.
Attention
Absent use of double wrenches for fastening may
lead to deformation of operating valve, causing entry
of nitrogen into outdoor unit.
