The problem
SHOULD AN ICE BLOCKAGE OCCUR BETWEEN THE AIR DRYER AND THE WET TANK DURING EXTREMELY COLD WEATHER CONDITIONS, THE PRESSURE BETWEEN THE COMPRESSOR AND THE LINE BLOCKAGE WOULD BUILD UP AND COULD LEAD TO A VIOLENT EXPLOSION.
What owners should do
A PRESSURE RELIEF PROVISION WILL BE INSTALLED AT THE DRYER TO PREVENT PRESSURE BUILD UP.
