23).  Press ‘Enter’ to accept new value

Note:  If the hour setting is ‘IGNORE’, Press ‘Enter’
again to move the cursor under the “Day of week + on/
off”.  Repeat steps a through b (or c) as needed.

c. Use the Up and Down arrow buttons to set minutes (00,

10, 20, 30, 40, 50; not shown if hour setting is
‘IGNORE’).  Press ‘Enter’ to accept new value and
return to “Day of week + on/off”.  Repeat steps a
through c as needed.

d. Push ‘ESC’ at any time to return to the Main Menu.

Hours To Service

a. Use the ‘Up’ and ‘Down’ arrow buttons to scroll through

the range of permissible values (0 to 8760) before
service reminder is initiated.  Press ‘Enter’ to accept
new value. (Only hours that refrigeration compressor is
operating are counted).

b. Press ‘ESC’ at any time to return to the Main Menu.

NOTE: On dryers with air-cooled condensers, regular
condenser cleaning is recommended. Dirtiness of
ambient air at installation site will determine frequency
of  service.  Typically once a month is recommended.
Dryers contain an integral 3 micron filter.  As the filter
element accumulates solid contaminants, differential
pressure increases.  Solid particulate load in the
compressed air supply will determine frequency of
service.  Typically element changeout is recommended
at least annually.

5.

Push ESC button to exit program mode

NOTE: If after 60 seconds no button is pressed while in
Program Mode, the audible alarm sounds for five (5)
seconds.  Dryer will resume previous operating mode.

6.

Manual Operation

a. To manually turn the refrigeration system on or off use

‘On/Off’ button; Push ‘Schedule On/Off and Enter’
button to return to schedule.

NOTE: After power interruption dryer will reenergize in
Manual override, refrigeration system off. To restart
Schedule:  Push ‘Schedule On/Off and Enter’ button.

C.

Starting dryer

IMPORTANT: Dryer must be energized 24 hours before starting
refrigeration compressor.

NOTE: It is recommended that dryer be started 15 minutes
before compressed air flow begins.

1.

On water-cooled models: after 24 hours, begin cooling
water flow.

2.

Check for proper electrical voltage.

3.

Slowly pressurize unit air side by opening inlet isolation
valve. Check for leaks.

4.

After 15 minutes, open outlet isolation valve slowly.

5.

Close air bypass valve.

6.

Dryer may be operated in Manual or scheduled modes.

NOTE: Check for correct phasing of unit. On air-cooled models:
check fan rotation (air must be pulled through the condenser.)
Fans may not start immediately or may cycle on and off. If
rotation is in the wrong direction follow the procedure below. On
water-cooled models: After starting dryer if an unusual noise is
heard and the discharge line does not get hot, stop the dryer,
reverse two power leads, restart, and verify discharge line gets
hot.

Manual mode - push On/Off button - refrigeration compres-
sor will start and run, green Compressor-on light will
illuminate. In this mode compressor will run continuously
and will not be turned on and off by the monitor. MANUAL
OVERRIDE will appear on interface panel.

Schedule mode - push Schedule On/Off and Enter button.
SCHEDULE RUNNING will appear on the interface panel.
The refrigeration compressor will continue to be on or off
(as selected in the Manual Override Mode) until the next
scheduled event. The compressor will then turn on or off as
programmed.

NOTE: Schedule may be returned to the manual mode at any
time using the ‘Schedule On/Off and Enter’ button. MANUAL
OVERRIDE will appear on interface panel. To reinstitute
Schedule, push the ‘Schedule On/Off and Enter’ button again.

NOTE: Restart after the power interruption. Unit will be in
MANUAL OVERRIDE mode, refrigeration compressor, off when
power is restored after power interruption.

7.

To reinstitute SCHEDULE RUNNING: push ‘Schedule On/
Off and Enter’ button.

IMPORTANT: Dryer must be energized 24 hours before
refrigeration compressor is started

D.

Operating check points

1.

Check that green Power-on light is illuminated

2.

Check that green Compressor-on light is illuminated if
dryer is on in the manual mode or it is a scheduled on time

IMPORTANT:  Refrigeration compressor must be restarted after
power interruption.

3.

Check interface panel

NOTE: Interface panel will scroll through three screens (Current
Time/Operating Status, Hours to Service, and Total Operating
Hours).

a.

Verify that current time is correct

b.

Check HRS TO SERVICE: this indicates time
remaining until service is required; allow time for
required maintenance items to be ordered

c.

Check operating status:

MANUAL OVERRIDE - Dryer is either running
continuously (not being controlled by the scheduled
on/off times) or the refrigeration compressor has been
shut off using the ‘On/Off’ button.

SCHEDULE RUNNING - Refrigeration compressor
is being turned on and off by the monitor per-
programmed schedule (see B.3. to set schedule).

d.

Check Temperature indicator - indicator should read in
the green area.
