PSE 325-1000 60Hz
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 lifting. 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 Only competent personnel trained, qualied, and approved by
Parker should perform installation, commissioning, service and repair
procedures. Use caution when near the dryer and wear the proper pro-
tective 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 re risk (ref. EN378-
3).
YComply with the instructions given in par. 9.2 and 9.3.
For reliable operation and warranty purposes, proper pre-ltration is rec-
ommended. Without a pre-ltration the dryer may see degradation in
performance and/or permanent dryer failure. Warranty will be voided if
the inlet air quality does not meet the required ISO8573-1 Class for par-
ticulate and total oil. Seller is excluded from any obligation of compensa-
tion or refund for and direct or indirect damage caused by its absence.
YPre-lter element must be replaced at least once a year, or sooner
as per manufacturer recommendations.
YCorrectly connect the dryer to the compressed air inlet/outlet con-
nections using pipe or hose that meets the temperature and pressure
requirements of the air compressor output. (see par.9.3 and 9.6).
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 lter be installed
on the cooling water inlet (not included with PSE as standard).
Y, Inlet condensation water characteristics:
Temperature ≥50°F (10°C) CL-<50 ppm
ΔT IN/OUT 41-59°F
5-15°C CaCO370-150 ppm
Max % glycol 50 O2<0.1 ppm
Pressure 43.5-145 PSIg
(3-10 barg) Fe <0.2 ppm
PH 7.5-9 NO3<2 ppm
Electrical
conductivity 10-500 μS/cm HCO3-70-300 ppm
Langelier
saturation
index
0-1 H2S<0.05 ppm
SO4
2- <50 ppm CO2<5 ppm
NH3<1 ppm Al <0.2 ppm
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 Environment
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
YMake 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 owing through the dryer;
• the power supply is correct;
• Note: If using a Wc version, open the cooling water circuit 5 minutes
before starting the dryer.
4.2 Starting
a) Switch the power on by turning the MAIN SWITCH “&” to
“I ON”:the dryer is powered and the word “OFF” appears on the
display.
!THE CRANKCASE HEATER MUST BE SWITCHED ON 12
HOURS BEFORE STARTING THE DRYER.
b) Press set to start (for model 325-500).
Press to start (for model 700-1000).
c) Start the dryer before the air compressor;
YThe 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, then slowly & partially open the inlet valve. Let the
dryer reach line pressure before fully opening the inlet valve.
e) Once the dryer is at line pressure and the inlet valve is completely
open, 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 eld adjustment
to settings is not required. See section 5 for navigating controls.
• In the event of unforeseen excess air ows or spikes in moisture load,
by-pass the dryer to avoid overloading it.
• Avoid inlet air temperature uctuations.

English 3/12
PSE 325-1000 60Hz
4.4 Stop
a) Stop the compressor or the air ow through the dryer and wait 2
minutes before shutting down the dryer;
b) Close the inlet air valve to ensure compressed air does not enter the
dryer when disconnected or if an alarm occurs.
c) Press set to stop the dryer (for model 325-500).
Press to stop the dryer (for model 700-1000).
d) Turn the MAIN SWITCH “&” to “O OFF” to switch power off.
YWc version, close the water circuit with the dryer stopped.
