Make drain connection of equal to or larger size than the drain size on the dryer to the
Pioneer Oil-
Sep Coalescer Plus
(optional). The oil-water drain should be connected to an appropriate drainage.

Start Up
Purge clean all compressed air piping prior to installation and start up of the unit, to remove all pipe
scale, weld sludge, rust, and free moisture. In a newly installed piping system, the prefilter element may
need to be changed within a few days of installation to remove weld sludge, rust, and etc.
After all power and connections have been made, the unit is ready for operation. Generally, dryers
are shipped with a charge of refrigerant, with all refrigeration service ports closed. Switch the main
disconnect on, allowing the compressor crankcase heater (standard in three phase units) to warm up the
compressor lubricating oil and evaporate liquid refrigerant in the compressor.
Leave crankcase heater
on for a minimum of eight (8) hours before switching the dryer on.
Units equipped with semi-hermetic compressors are shipped with vibration blocks. These
must be removed prior to start up.
Start the dryer and observe the suction gauge pressure. Normal operating range is 55-67 PSIG (3.8–
4.6 BarG) for R-22 units, and 31-37 PSIG (2.1-2.5 BarG) for R-134a units. On units equipped with
Micro-Monitors, the normal suction temperature range is 35 to 45
o
F (2 to 9
o
C). The data label indicates
the type of refrigerant in the unit. After the dryer has run for about ten minutes, open the compressed air
