• Regularly check the reliability of the installation frame.
7.9 TUBING CONNECTION
• Detach the valve cover of outdoor unit.
• Align flaring nut to the thread center, and screw the nut tightly by hand.
• Screw tightly the flaring nut with torque spanner until the torque spanner produces "click" sound.
• It is recommended to use torque spanner to connect the tubing. If other flexible or fixed spanner is used,
it may damage the horn mouth due to improper force.
• The bending angle of the tube should not be too small or the tube may break up, so the service personnel
should use tube bender to bend the tube.
• Never let water, dust or sand gets into the pipe.
