Stopping the dryer

a) Use the switch to stop the dryer.
b) Stop the dryer 2 minutes after shutting down the air compressor or interrupting
the air flow to the dryer.
Avoid allowing compressed air to enter the dryer when the dryer is
switched off or when it is in an alarm situation which stops the refrigeration
compressor.
3.4

Operation

S The dryer operates automatically. It is factory set for a dew point of 37˚F (3˚C)
(ISO 7183, Part 2) and therefore requires no further calibration.
S Do not exceed the machine's design limits, bypass excess air flow and check the
unit model and/or installation.
S For maximum performance from your dryer, follow the maintenance schedule de-
scribed in Chapter 4.
S The sound pressure level recorded for these dryers 40 inch (at 1 metre) from the
machine in free field conditions is less then 50 dB(A) (models SR- - 5 --- SR- - 15),
55 dB(A) (models SR- - 25 --- SR- - 100)
Fig. 5 shows the Dryer's refrigeration and air circuits.
