4. Safety & Warning Information
This section contains general information about safety and warning points to consider and
adhere to during installation, operation, and maintenance of your air dryer. PLEASE
READ THIS SECTION BEFORE PERFORMING ANY OPERATION OR
PROCEDURE ON YOUR AIR DRYER.
Additional warnings specific to an operation or procedure will also be presented
throughout the following sections. These will include the symbol as well as a label of
“WARNING!”, “CAUTION!”, or “IMPORTANT!” Please be sure to pay close
attention for these warnings and read them as you encounter them.
WARNING!
For your safety, all the information in this User’s Guide must be
followed to minimize the risk of electrical shock and prevent
property damage or personal injury.
WARNING!
Extreme care should be exercised to avoid contact with live
electrical circuits. Many procedures performed during installation,
operation, testing, and maintenance of this air dryer require the
equipment to be running, creating a situation for potential electrical
shock. It is highly recommended that you remove all jewelry before
performing any procedures.
WARNING!
Internal surfaces may be hot. Use care when coming into contact
with internal components as there is a potential for some of these
components to become hot when in operation or standby.
WARNING!
High Noise. RFS air dryers are meant to be installed in an unattended
area.

6.5.12 Power the dryer ON.
NOTE: The Compressor and
heatless dryer will start,
creating air flow through the
Outlet Port.
6.5.13 Set the System Pressure:
With Compressor running:
6.5.13.1 Pull the Capacity
Control Valve knob
out.
6.5.13.2 Turn the knob until
the reading on the
pressure gauge is:
80 PSI (551.6 KPa)
for W & WLP
NOTE: 90 PSI (620.5 KPa)
may be used on W & WLP
dryers in low flow applications
to maintain low humidity.
6.5.13.3 Push the knob in to
lock.
6.5.14 Let the dryer run until the Humidity drops below 2% (may take up to 15
minutes). Press the RESET Button if the dryer goes into SHUTDOWN
mode.
6.5.15 Power the dryer OFF.

Radio Frequency Systems BD1500W Series Air Dryers User’s Guide
Page 18 of 98 100518834 – Rev. B
6.5.16 Remove the Precision Bleed Orifice fitting from the Outlet Port by
pressing the ferrule down
then pulling the fitting
upward.
NOTE: Save this fitting for use in
low flow applications.
6.5.17 Connect the air supply
line to the Outlet Port.
NOTE: If the downstream system is pressurized prior to installation of
dryer, make reasonable attempts to install the dryer while minimizing system
depressurization. Complete depressurization may result in ambient moisture
being introduced into the system, which may require extended run time and
dryer cycling to reduce or eliminate. Ambient moisture in the downstream
system may result in high humidity alarms and shutdowns.
6.5.18 When connecting to a completely depressurized system, a high
compressor run time alarm may be triggered. This alarm will need to be
manually reset until the system is pressurized and humidity levels have
reached their defined levels.

Radio Frequency Systems BD1500W Series Air Dryers User’s Guide
Page 19 of 98 100518834 – Rev. B
NOTE: For all dryers with minimal
FLOW:
Install the included Precision
Bleed Orifice fitting to
maintain a constant air flow.
6.5.19 Power the dryer ON.
6.5.20 Set the Static Pressure:
6.5.20.1 Pull Static Pressure
Regulator knob out.
6.5.20.2 Turn knob until the
reading on the pressure
gauge is:
17 PSI (117.2 PSI) for
W & WLP

Radio Frequency Systems BD1500W Series Air Dryers User’s Guide
Page 20 of 98 100518834 – Rev. B
6.5.20.3 Push knob in to lock.
6.5.21 Set the Outlet Pressure:
6.5.21.1 Pull the Outlet
Pressure Regulator knob
out (or loosen the
retaining nut – LP
Models).
6.5.21.2 Turn knob until
Outlet Pressure (OUTP) reading is at the desired setting.
6.5.21.3 Push knob in to lock (or tighten the retaining nut – LP Models).
6.5.22 Check for air leaks:
NOTE: This is a general procedure that can be applied to any fitting or hose
that has air pressure in it. DO NOT SOAP TEST THE HUMIDITY
SENSOR FITTING. DAMAGE TO THE SENSOR MAY OCCUR.
With Compressor NOT running:
6.5.22.1 Listen for any ‘hissing’ sounds which may indicate a fitting or hose
air leak.
With Compressor running:
6.5.22.2 Use a 1-inch paint
brush to dab soapy water
on the air fitting or hose
connection to be tested.
If air bubbles appear at the
connection, this indicates that
air is leaking from the
connection.
