English

2 Introduction

This manual is in reference to Parker PSE325-1000 refrigeration dryers
designed to remove water vapor from compressed air.
2.1 Transportation
The packed unit must:
• remain upright;
• be protected against atmospheric agents;
• be protected against impacts.

2.2 Handling

Use a properly suited fork-lift truck for lifted. Avoid any type of impact
when handling the dryer.

2.3 Inspection

a) All the units are assembled, wired, charged with refrigerant and oil
and tested under standard operating conditions in the factory;
b) on receiving the machine check its condition: immediately notify the
transport company in case of any damage;
c) To avoid unnecessary handling of the dryer, unpackage the unit as
close as possible to the place of installation.

2.4 Storage

IIf stacking is required, follow the instructions stated on the packaging.
Keep the unit packaged in a clean, dry area that is protected from the
elements, direct sunlight and/or other harsh conditions.

3 Installation

Y
For the correct application of the warranty terms, follow the instruc-
tions given in the start-up report, fi ll it in and send it back to Seller.
Only competent personnel trained, qualifi ed, and approved by Parker
should perform installation, commissioning, service and repair proce-
dures. Use caution when near the dryer and wear the proper protective
equipment.

3.1 Procedures

Install indoors in a clean, dry area that is protected from the elements,
direct sunlight and/or other harsh conditions.
!
The installed product must be protected against fi re risk (ref. EN378-
3).
Y
Comply with the instructions given in par. 9.2 and 9.3.
All dryers must be fi tted with adequate pre-fi ltration near the dryer air
inlet. Seller is excluded any obligation of compensation or refund for any
direct or indirect damage caused by its absence
Y
Pre-fi lter element (for 3 micron fi ltration or better) must be replaced
at least once a year, or sooner as per manufacturer recommendations
Y
Correctly connect the dryer to the compressed air inlet/outlet con-
nections (see par.9.3 and 9.6).
PSE 325-1000 60Hz

3.2 Operating space

Leave a space of 5 ft (1.5 m) around the unit.
Leave a space of 6.5ft (2 m) above dryer models with vertical condensa-
tion air expulsion.
3.3 Condenser Types
Air-cooled version (Ac)
Standard condenser type for all PSE models. Note: Do not duct away,
create cooling air recirculation situations or obstruct the ventilation grills.
Water-cooled version (Wc)
Water-cooled version (Wc) - Optional condenser type only available on
PSE1000 and up. Note: It is recommended that a mesh fi lter be installed
on the cooling water inlet (not included with PSE as standard).

Note: For special cooling water types, such as demineralized, deionized
or distilled, it is necessary to contact the manufacturer to verify if the
standard PSE condenser is suitable.
3.4 Installation Environmen
PSE dryers are to be installed indoors only. To prevent damage to the in-
ternal parts of the dryer and air compressor, avoid installations where the
surrounding air contains solid and/or gaseous pollutants (e.g. sulphur,
ammonia, chlorine and installations in marine environments).
The ducting of extracted air is not allowed for versions with axial fans.

3.5 Electrical connection

Use approved cable that conforms with the local laws and regulations
(for minimum cable section, see par. 9.3).
Install a differential thermal magnetic circuit breaker with contact open-
ing distance 0.12in (3 mm) ahead of the system (RCCB - IDn = 0.3A) (see
relevant local regulations).
The nominal current of the magnetic circuit breaker must be equal to the
FLA with an interruption curve type D..

3.6 Condensate drain connection

Y
Make a connection to the draining system. Avoid connecting to a
closed circuit shared by other pressurized discharge lines. Ensure proper
condensate discharge. Dispose of all the condensate in conformity with
current local environmental regulations.

4 Commissioning

4.1 Preliminary checks

Before commissioning the dryer, make sure:
• All information in section 3 was read, understood and carried out
properly;
• the compressed air inlet and outlet isolation valves are closed and no
air is fl owing through the dryer;
<50 ppm
• the power supply is correct;
• Note: If using a Wc version, open the cooling water circuit 5 minutes
70-150 ppm
before starting the dryer.
<0.1 ppm

4.2 Starting

<0.2 ppm
a) Switch the power on by turning the MAIN SWITCH "
"I ON":the dryer is powered and the word "OFF" appears on the dis-
<2 ppm
play.
70-300 ppm
!
THE CRANKCASE HEATER MUST BE SWITCHED ON 12 HOURS
BEFORE STARTING THE DRYER.
set
<0.05 ppm
b) Press to start (for model 325-500).
Press to start (for model 700-1000).
<5 ppm
c) Start the dryer before the air compressor;
<0.2 ppm
Y
The fan will turn in the opposite direction which can result in dam-
age due to the air exiting the dryer cabinet from the condenser grill (side)
instead of from the fan grill (top). In this type of event, immediately invert
the two phases.
d) Wait 5 minutes, once at line pressure, slowly & partially open the
outlet valve to pressurize downstream equipment/processes. Once
downstream is up to line pressure, fully open the outlet valve.
e) slowly open the air outlet valve: the dryer is now drying.
Phases Monitor
If appears to display an alarm, during the start up of the dryer, the user
must verify the wiring of the input terminals of the disconnecting switch
of the dryer.

4.3 Operation

• Always leave the dryer on when the compressor is on and working.
• The dryer operates automatically , therefore constant fi eld adjustment
to settings is not required. See section 5 for navigating controls.
• In the event of unforeseen excess air fl ows or spikes in moisture load,
by-pass the dryer to avoid overloading it.
• Avoid inlet air temperature fl uctuations.
