FCC Compliance
The condensate drain series ZLD-006 to ZLD-330 is, according to the
manufacturer/applicant, primarily intended for use in industrial plants as "digital
devices" and "unintentional radiators". Therefore the drain series falls under the
category of exempted devices, according to FCC, CFR 47, 915.103 b).
Only the general requirement that a device must not emit electromagnetic
disturbances are to be fulfilled, and fulfilment is confirmed through an EMC report
according to the European EMC requirements for the CE mark.

General Information
About this operating manual
Signs and symbols
►Procedures that must be completed in the indicated sequence are numbered.
Items in lists are highlighted with grey boxes.
Note:
Always comply with these instructions to ensure safe and efficient
operation of the machines and devices.
Caution!
These safety notes help prevent damage to property and must always be
adhered to.
Danger!
These danger notes with a grey background warn against personal injury
and/or danger to life and limb; danger notes help you to avoid serious or
life-threatening situations for yourself and/or third parties.
Target group of these operating instructions
This operating manual is intended for all persons who work with the condensate
drain. We assume that these persons have technical qualifications, e.g. as pipe-
fitters or electricians.
About your safety
Please observe the following general safety instructions:
Caution!
All maintenance work must be completed by suitably qualified and
authorized specialist personnel.
Risk of injury from escaping compressed air!
Never remove any parts of the condensate drain or perform any
maintenance as long as the unit is pressurized! Rapidly escaping
compressed air can cause serious injuries.
Prior to any work, depressurize the unit, and verify that it has been
depressurized.
Warning! Risk of injury from electrical voltage
All work on electrical components must be carried out by suitably
qualified specialist personnel!

Proper use of the condensate drain
The condensate drain must only be used for the removal of standard
condensates (condensed water and liquid oil) from compressed air systems. Any
other use is deemed improper.

Function
The condensate enters the unit through the inlet (1 or 2) and collects in the
collecting chamber (3). When the collecting chamber is completely filled with
condensate (4), the condensate is drained through the outlet (5) until the
chamber is emptied. An integrated flow regulator (6) prevents rapid
depressurization when the valve is opened, ensuring smooth and quiet drainage
of the condensate.
The different condensate drain statuses are indicated by an LED in green,
orange and red. A green LED indicates normal and trouble-free operation. An
orange LED indicates that no condensate has been drained for a period of 15
hours. After condensate has been drained off, the LED changes to green.
5

The LED flashes slowly in red if the condensate cannot be drained off within the
set time and an internal cleaning program has been started. After successful
cleaning the drain returns to normal operating mode. If the cleaning program
cannot be completed successfully, an emergency program is started and an
alarm signal is issued (LED flashing rapidly in red).
Installation
All work at the pipelines and on the electrical components must be carried
out by authorized and suitably qualified technical personnel.
Requirements for installation
For proper installation of the condensate drain, the operator must provide the
following:
Proper connections and lines for the condensate inlet and outlet. For a list of
connection sizes, please refer to the technical data on page 17.
All lines and connections must be adjusted to the actual operating pressure.
Use only ball valves as shut-off valves.
Ensure that the condensate drain is connected to the correct electrical
voltage.
Basic requirements for installation
When installing the condensate drain, observe the following general instructions:
Avoid plumbing multiple
condensate lines into one
drain!
If condensate needs to be
drained at several locations,
separate condensate drains
should be used. Otherwise,
undesired flow will occur.
incorrect correct

Observe downward slope
into the condensate drain!
Ensure that the condensate
line entering the drain is
properly sloped in a
downward manner.
Otherwise, an air bubble
might prevent condensate
from entering the drain.
incorrect correct
Install vent line!
If the bottom condensate
inlet is used, install a vent
line. Otherwise, air bubbles
trapped in the condensate
inlet piping might prevent
condensate from entering
the chamber.
incorrect correct
Observe levels!
The switching level of the
condensate drain must be
lower than the vessel.
Otherwise, condensate
might be backed up in the
vessel.
incorrect correct
Prevent carry-over of
condensate!
Straight pipelines might
lead to carrying over of
condensate. Install suitable
condensate traps (driplegs).
incorrect correct

Connection of condensate inlet
20-606 and 20-613 are equipped with a top condensate inlet only, while model
20-623 has a revolving top inlet and a bottom inlet for condensate.
Note:
For installation, we recommend using the appropriate Parker
installation kit consisting of a ball valve with fittings.
Use open-ended spanner!
Never turn the condensate
drain to install it into the
pipeline! Always use an
open-ended spanner to
install the condensate drain.

Installation of 20-606
►Under certain circumstances, the 20-606 can be mounted directly onto the
filter bowl. Ensure that the drain is in vertical position (maximum permissible
deviation from perpendicular: +/- 5 %).
The integrated vent ensures proper condensate inlet to the collection chamber.
Installation of 20-613 and 20-623
►Turn the upper inlet piece to the desired position:
—Pull pin.
—Turn inlet piece.
—Push back pin.
►Select the condensate inlet connection to be used.
►Ensure that the drain is in vertical position (maximum permissible deviation
from perpendicular: +/- 5 %).
►Connect condensate inlet connection to feed line. Install vent line, if required.
►Check connections for leakage.

Connection of condensate outlet
The condensate drain delivery includes a 0.3-0.4 in hose tail.
Note:
The water column in the condensate outlet should not exceed 6.5 ft.
The condensate outlet lines should not be pressurized but open.
►Connect the condensate outlet to the condensate drain line.
Connection to power supply/potential-free contact
Warning! Risk of injury from electrical voltage
All work on electrical components must be carried out by suitably
qualified technical personnel!
Model 20-623 is equipped with a potential-free contact, in addition to the main
power connection (not available for 20-606 and 20-613). Model 20-623 therefore
features two connections with matching adapters:
Adapter for supply voltage: magnetic valve connector "type B plug" industrial
standard (0.43 in) 2 + PE (see figure, item 1)
Adapter for potential-free contact: magnetic valve connector "type C plug"
industrial standard (0.37 in) 3 + PE (see figure, item 2)
Connection to supply voltage
Beware of electric shock in case of a fault!
The drain features a ground connection. Its purpose is to provide a safety
cut-out of the condensate drain in case of an error, provided that the drain
is plugged into a ground fault circuit interrupter has been installed in the
electrical line.
Otherwise there is the risk of an electric shock in case of moisture
penetration.
We absolutely recommend that you install a ground fault circuit
interrupter in the power supply line prior to connecting the condensate
drain.
►Attach type B plug to the cable. Observe pin assignment (see figure).
