Ultra Air Refrigerated Dryers
201 Series Instruction Manual
Installation (continued)
condenser with a resulting increase in workload on the refrigeration compressor. This can conceivably
reduce the life of the equipment and hinder its operation. Dryers operating in ambients lower than 40ºF
ambient must be ordered with a low ambient control option.
Recommended Installation
2
1) Drain valve:
automatically expels water on timed sequence, eliminating the potential of water buildup.
2) Water separator:
uses centrifugal action to spin large volumes of liquid out of the system. Use with
drain valve is highly recommended.
3) Heavy duty coalescer (1.0 micron):
removes bulk amounts of oil aerosols through impingement sepa-
ration. Should have drain valve to prevent moisture collection. Protects refrigerated dryer from oil coating
on interior walls, as oil acts as an insulator and reduces the efficiency of the dryer.
4) UA201 Series refrigerated air dryer:
Lowers compressed air dewpoint.
5) Heavy duty coalescer (1.0 micron)
Drain Connections
All separators on the UA201 models and prefilters on models UA201-125 and up are equipped with a
timer actuated solenoid valve drain system. Prefilters on models UA201-10 through UA201-100 come
standard with an automatic float drain. The drain line from the dryer should be sloped and emptied into a
floor drain or connector that is lower than the bottom of the separator in the dryer so the condensate that
is removed by the dryer can be drained by gravity.
Electrical Requirements
The nameplate on the instrument panel on each unit identifies the power supply requirements. A suitable
wall-mounted disconnect switch in accordance with national and local code requirements is recommend-
ed.
