1.2 Mounting
Mount the dryer on a level solid surface. Holes are provided in
the dryer base to permanently mount the dryer to the floor.
1.3 Piping Connections
A. Air Inlet - Connect compressed air line from air source
to air inlet. (Reference markings on dryer or see callout
drawing on page 13 for air inlet/outlet connection loca
-
tions.)
NOTE:
Customer piping needs to be properly supported.
Use back-up wrench when making piping connections.
Refer to Serial Number Tag for maximum
working pressure. Do not exceed dryer’s Maximum Working
Pressure.
NOTE:
Install dryer in air system at highest pressure possible
(e.g. before pressure reducing valves).
NOTE:
Install dryer at coolest compressed air temperature
possible. Maximum inlet compressed air temperature: 120°F
(49°C). If inlet air exceeds this temperature, precool the air
with an aftercooler.
B. Air Outlet – Connect air outlet to downstream air lines.
NOTE:
Customer piping needs to be properly supported.
Use back-up wrench when making piping connections.
C. Bypass piping – If servicing the dryer without interrupting
the air supply is desired, piping should include inlet and
outlet valves and an air bypass valve.
D. Water cooled models – cooling water inlet and outlet
1. Connect cooling water supply to cooling water inlet.
2. Connect cooling water return line to cooling water
outlet connection.
NOTE:
Strainer and water regulating valve are supplied on
water cooled models.
1.4 Electrical Connections
IMPORTANT:
Use copper supply wires only.
A.
Dryer is designed to operate on the volt-
age, phase, and frequency listed on the
serial number tag.
B. Electrical entry on larger dryers is through
a hole in the cabinet. It is located on the right side panel
when facing the front of the unit. Connect power source
to terminal strip in electrical enclosure as shown on the
wiring diagram included with the dryer.
NOTE:
Refrigeration condensing unit is designed to run con
-
tinuously and should NOT
be wired to cycle on/off with the air
compressor.
1.5 Moisture Separator
A. Separator has an external drain which auto
-
matically discharges collected condensate.
NOTE:
It may be desirable to pipe the con-
densate from the Automatic Drain outlet to a
suitable drain.
B. For manual draining, convenient dryer depressurization,
and drain valve maintenance, a three-way valve assembly
is installed between the drain port on the moisture separa-
tor and the drain valve. On all models, the three-way
valve is mounted to the base pan. Review the following
for proper drain function:
• Automatic Draining - Valve handle should be positioned
parallel to the valve body (as shown), with the arrow
on the handle pointing toward the drain valve. In this
position, condensate will flow from the bowl to the drain
valve.
• Drain Isolation (Shutdown) - Valve handle shall be
turned perpendicular to the valve body (rotate 90°). In
this position, condensate flow is shutoff.
Solenoid Valve
Automatic Discharge
Line
Manual Discharge Line
3-Way Valve
Drain Inlets
• Manual Draining - Drain valve handle shall be rotated
slightly past the drain isolation position to allow
throttling through the valve for manual discharge and
depressurization.
NOTE:
Discharge is at system pressure. Drain line should be
anchored.
NOTE:
Condensate may contain oil. Comply with applicable
laws concerning proper disposal.
