We highly recommend installing Primary –Pro insulation for the insulation of the outdoor unit pipe work. This is available at most suppliers

​

• The pipe work must be insulated completely through the length of the wall.

• The Insulation must be a minimum of 19mm thick for up to 20 metres external pipe work

• Class O Insulation is not UV stable, therefore must not be used

• Climaflex Polyethylene Pipe Insulation (Grey Lagging) must not be used outside

• All joints must be fully sealed to reduce heat loss
