Connecting Compressed Air; Condensate Drains - NovaTec NovaDrier ND-7 Instruction Manual

3.3.2 Connecting Compressed Air

Connect a clean, ozone-free, vapor-free and liquid water-free compressed air line to the
compressed air inlet ball valve located on the left side of the control panel.
See the minimum compressed air inlet line size requirement below. The
pressure of the compressed air to the system should be at least 85 psig but
not more than 125 psi (note that the system will run more efficiently at higher
air pressures). The inlet compressed air temperature should be less that 100°F. Note
that the (2) coalescing inlet compressed air filters on the NovaDrier each have an
internal condensate trap that is designed to remove small amounts of water droplets
from un-dried incoming compressed air but they are not designed to remove liquid
water. Make sure that hazardous vapors, like solvents or ozone, are not being
introduced into the compressed air system that is feeding the NovaDrier.

3.3.3 Condensate Drains

Connect the automatic compressed air condensate drains at the bottom of the
(2) compressed air filters on the side of the cabinet, so the condensate is
captured and disposed of properly. If the drains are not piped away, oily water
may spray down periodically from the automatic drains. Use a 1/8" npt male
fitting to connect into each drain.
