• The refrigerant system must be completely sealed in order for the

Blueridge Ductless System to perform optimally and prevent damage to

the equipment.

• If a refrigerant detector is not available, soap and water can be used.

• The lineset(s) should be pressurized using dry nitrogen, 100-200 psig.

Then using a soap bubble solution, spray down all flare joints, and watch

for bubbles to appear. If any bubbles are present, tighten the flare nut,

or if nut is already tight, you may have to disconnect, and inspect flare or

re-flare the copper.

NOTE

Leakage detection is extremely important. If a leak is discovered

after the charge (refrigerant) has been released, the system can-

not be topped off at that point. Any remaining refrigerant would

need to be removed, a vacuum pulled on the entire unit, and the

system fully recharged by weight.

Single Zone

Vacuuming the lines to rid the air and moisture is essential in every Blueridge

Minisplit System. This can be done using a vacuum pump, gauges, and thor-

ough training, which prevents personal injury and/or damage to the equipment.
