Initial startup
To start up the air treatment unit for the first time or after a long period of standstill,
proceed as follows:
1. Close the air supply from the compressor towards the unit by closing the inlet valve.
2. Close the outlet valve.
3. Remove the silencers of the dryer to prevent them from getting clogged by dust from the
new desiccant. Wear a dust mask, safety glasses and ear protection. (This is only
required at initial startup or after the desiccant was replaced).
4. the co Start the compressors by starting the ECO on the main controller.
5. Slowly open the inlet valve of the air treatment unit.
6. Check all connections for air leaks and remedy if necessary.
7. Let the unit operate for several hours with the external outlet valve closed.
8. In case the silencers were removed, refit the silencers.
9. Check the dew point downstream of the purifier unit. When the atmospheric dew point on
HTM models has reached -40 ˚C to -45 ˚C (-40 ˚F to -49 ˚F) or pressure dew point on
NFPA models has reached -25 ˚C to -30 ˚C (-13 ˚F to -22 ˚F), open the external outlet
valve and set the flow according to the specification of the unit (see section Technical
data). Make sure that the air flow does not exceed the specified flow and check what is the
highest temperature the ambient air will have. This flow must not be directed into the
air net but needs to be blown off via another way! The initial dew point of the air leaving
the unit will be higher than normal after starting. Since the air needs to be according to
Pharmacopoeia regulations, it is necessary to run the dryer for minimum 24 hours with the
outlet air blown off to make sure that the pipes are not contaminated.
10. When the atmospheric dew point for HTM models has reached -48 ˚C (-54 ˚F) or for
NFPA reached -32 °C (-256 °F), it is necessary to perform a validation of the air quality
according Pharmacopoeia. When the quality of the air is confirmed, change over from blow
off circuit to the air system by switching these valves. The records of these tests must be
kept by the user at all times.
11. Gradually open the external outlet valve.

At initial startup, and specially when the dryer is loaded from the beginning, it can take a
long time before the dew point is reached.
It is therefore recommended to operate the dryer for a number of days with the outlet valve
closed.
• All valves, couplings and pipes used/installed after the unit must be free from oil and
grease (hydrocarbon contamination below 550 mg/m
50 micrometer).
• For the location of the external inlet valve and external outlet valve (customer's
installation), see section
• Before starting the unit make sure that all pipes are connected and that items in drains
or pipes for protection during transport are removed.
