DRYER OPTION - OPERATION AND MAINTENANCE
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 (Figure 4b)��
b)
To protect dryer equipment, always start up the
dryer before activating the air compressor��

After stopping the dryer, wait at least 3 minutes before
starting it again��
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��
c)
Wait about 5 minutes until the dryer is running at the
correct operating temperatures and pressures before
starting the compressor��
d)
Always leave the dryer running while the air
compressor is operating, irrespective of load
condition��
STOPPING THE DRYER
a)
Use the switch to stop the dryer (Figure 4b)��
b)
Stop the dryer at least 2 minutes after shutting down
the air compressor or interrupting the air flow to the
dryer��
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��
