The UP series integrated dryer is not for use with the
low ambient or outdoor module options .
INSTALLATION
a)
Do not obstruct the dryer air grilles.
b)
Allow sufficient gap around the unit to facilitate
maintenance and ensure unimpeded air discharge
from the condenser.
c)
Avoid recirculation of hot condenser air back into the
condenser air inlet.
d)
Do not connect condensate drains common to
other pressurized drain lines in a closed circuit.
Make sure the outflow from the condensate
drains is unimpeded. Connect the condensate
piping in such a way to ensure that sound levels
are kept to a minimum during drainage. Ensure
that all condensate is disposed of in a responsible
manner, in accordance with local norms concerning
environmental protection.
e)
The ambient air around the dryer and compressor
must not contain solid or gaseous contaminants.
All compressed and condensed gases can generate
acids or chemical products which may damage the
compressor or components inside the dryer. Take
particular care with sulphur, ammonia, chlorine and
installations in marine environments. For further
advice or assistance consult your local
Ingersoll Rand representative.
ELECTRICAL CONNECTION
The dryer is powered from single–phase that must be
supplied separately from the compressor three–phase
supply. The dryer should be connected to a single phase
supply in accordance with local requirementsand codes.
CONDENSATE DRAINS
The dryer package is equipped with three automatic
condensate float drains in the moisture separator, the
dryer's compressor, and the post–filter. Each float drain
has a drainage port near the compressed air outlet on the
package.
THESE LINES MUST BE KEPT SEPARATE. Joining them will
cause improper operation.
START–UP AND OPERATION
Preliminary checks
Before starting the compressor, make sure that: The
power supply is correct for the dryer voltage.
Starting the dryer
a)
Use the green switch to start the dryer (Fig.2b).
b)
To protect dryer equipment, always start up the
dryer before activating the air compressor.
c)
Wait about 5 minutes until the dryer is running at the
correct operating temperatures and pressures before
starting the compressor.

DRYER OPTION
d)
Always leave the dryer running while the air
compressor is operating, irrespective of load
condition.
After stopping the dryer, wait at least 3 minutes before
starting it again.
STOPPING THE DRYER
a)
Use the switch to stop the dryer (Fig.2b).
b)
Stop the dryer at least 2 minutes after shutting down
the air compressor or interrupting the air flow to the
dryer.
Compressed air must never enter the dryer when the
dryer is switched off or when it is in an alarm situation
which stops the refrigeration compressor. The dryer can
be bypassed in these conditions.
OPERATION
•
The dryer operates automatically. It is factory set for
a dew point of 7° C (46° F) ISO8573-1 and therefore
requires no further calibration
•
For maximum performance from your dryer, follow
the maintenance schedule.
•
The dewpoint thermometer gives an indication
of performance of the dryer. When the dryer is
switched off at ambient conditions, it displays red.
In normal conditions it should be operating in the
green region. If the unit continues to operate in
the red region, contact your local Ingersoll Rand
representative.
Fig.1 shows the dryer's refrigeration and air circuits.
In order to bypass the dryer, stop the UP compressor
and lock and tag it out. Turn BOTH valves to a horizontal
position, as shown. The compressor can be run and
the dryer can be removed from the system for repair in
bypass mode.
Do not operate with valves in positions other than those
shown here. This may pressurize dryer with no air flow.
