PIPE SIZING GUIDE
Pipework sizes and routes should be set in accordance with good refrigeration practice.
PIPEWORK
INSTALLATION
The suction line should be insulated.
Liquid lines should be insulated in areas of high temperature or when exposed to
direct sunlight.
Special consideration should be given to vertical pipe runs and heat pump installation.
Unit performance will reduce if there are vertical rises of above 5m. Please consult
Airedale Service for risers above 10m.
When insulating refrigerant lines, cut approximately 30 - 50cm longer than the distance
between the units to ensure the insulation goes right upto the unit. Leave connections
uncovered for leak testing.
Remove burrs to the ends of the copper tube, holding the tube downward to avoid
allowing dirt to contaminate the tube.
Where applicable insert flare nuts removed from the pipework terminations and make a
flare at the end of the copper tube to conform with the following:
Inside surface is glossy and smooth
Tapered sides are of uniform length
Refrigeration lubrication is applied to mating surfaces
The installation of a sight glass close to the indoor unit is recommended.
Where applicable braze incoming pipe to rotalock service valve.
