To fasten the flare nuts, apply specified torque.
• When brazing, must be cool the pipe by wet cloths after removing the insulation tube and the cover plate.
• When brazing the gas tubing, cool the tubing with dampened shopcloths as you work, as shown in the figure below, to protect the
unit's thermistor from the heat generated by brazing.
• The type 200 indoor unit comes with a tube connector that is for liquid tubing. Configure as shown in the illustration and connect it.
When flaring the tube, put the flare nut onto it first and then flare it.
• Pipe insulation must be made after leak detection for tubing connection area was performed.
• Be sure to insulate both the gas tubing and liquid tubing.
In addition, wrap the supplied insulation material around the tubing joints, and fasten in place with vinyl tape or other means.
Failure to insulate the tubing may result in water leakage from condensation.
• Plug all gaps at tube through-holes in the unit with insulation or a similar substance to prevent air leakage.
