Fixing of the unit
1.Position of the wall hole
Wall hole should be decided according to installation
place and piping direction.(refer to installation drawings).
2. Making a wall hole
Drill a hole of 120X70mm dia. with a little slope towards
outside.
3. Piping connection

Maximum length and height difference of connecting pipe
Maximum length: 20m; Height difference: 10m
To ensure efficiency, shortest possible pipe should be used.
Cautions for pipe connection
Pipes free from twists, deformation, water, dust.
Dedicated tools for each R407C and R22
should be used and stored separately.
Optimized radii of bends
Insulation to be applied on all gaseous pipes
Flared section free from cracks

Apply refrigeration oil on the end of the pipe to be connected and on the flared section.
Align the pipes to be connected and tighten the nut. (See the figure)
