Safety instructions
Depressurize the system before carrying out any work on the piping or CDi-16B.
Installation and maintenance work may only be carried out when the device is not
under pressure.
Installation and maintenance work may only be carried out by trained and
experienced stuff.
Disconnect power supply before installation or any maintenance work.
Electrical work must always be carried out by qualified electrician.
Do not exceed max. operating pressure or operating temperature range (see data
label).
Do not use the device in hazardous areas with potentially explosive atmospheres.
Use original spare parts only.
Use the device for the appropriate purpose only.
Appropriate use
CDi-16B series electronic condensate drains are intended exclusively for draining
condensate from compressed air system (air compressors, air receivers/pressure
vessels, air dryers and air filters). This appliance must be used only for the
purpose for which it was specifically designed. All other uses are to be considered incorrect.
The manufacturer cannot be held responsible for any damage resulting from improper,
incorrect or unreasonable use.
Use genuine spare parts only. Any damage or malfunction caused by the use of ungenuine
parts is not covered by Warranty or Product Liability.

Operating
Condensate flows through inlet connection (1) and accumulates in the reservoir (2). Sensor
(3) is measuring condensate level. When reservoir (2) is detected full, sensor (3) sends signal
to electronic board. Electromagnetic valve (4) is than opened to discharge accumulated
condensate through outlet connection (5). When reservoir (2) has been emptied, the valve
(4) closes back without any losses of compressed air.
Led signal is indicating status of the device (see Functions).
If microcontroller registers faulty operation, device goes to alarm mode. At the same time
signal is sent through voltage free contact (see Functions).

Installation
Inlet pipe (1) size at least ½” (inner diameter > 13mm).
Collecting condensate line (3) size at least ¾ “.
At least 1% inlet pipe slope recommended.
Install ball valves (2) only.
Recommended connection (4) to water/oil separator.

The inclination of the unit must not exceed + / - 5° in both axes. If device is not installed
correctly it could cause faulty detecting of condensate level.

Connecting several condensate sources to one drain device causes operating problems (3).
Make sure that each drain source has its own drain device (4).

Trapped air prevents the condensate being purged from drain (5). During installation ensure
that no water pockets are formed in the piping (6).

8
When drainage is to take place directly from a pipeline it is recommended to arrange the
piping so that air flow is diverted (8).

In case there are problems with inflow, it is necessary to install a venting line (12). In this
case back connection is used as inlet and upper connection is used as air ventilation. Venting
line must never be installed as it is on pictures 9, 10 and 11.
Warning: Upper and back connections cannot be used as condensate inlet at the same
time.

Functions
LED indicator / TEST button
LED indicator:
LED indicates device condition.
1. Green ON: Power on, reservoir
empty, waiting condensate to
accumulate
2. Green FLASHES: Device is discharging
condensate
3. Red ON: Alarm mode
TEST button:
By pressing TEST button valve opens.

Operating modes
NORMAL
When sensor detects condensate the valve opens up to one second to discharge. Maximum
number of discharges in normal mode is up to 20.
OVERLOAD
If sensor detects condensed water continuously for 100 seconds, drain enters overload
mode. In this mode, the valve is opened for two seconds and closed for one second. This
cycle repeats for five minutes (up to 100 discharges). In case the reservoir empties during
overload mode, device enters normal mode again.
ALARM
If drain was still not able to discharge all condensate it enters alarm mode. In this mode, the
valve is opened for three seconds every fifty seconds. In case the reservoir empties during
alarm mode, drain enters normal mode again.
Alarm output
The switch is closed when CDi operates normally and it is open when CDi is in alarm mode or
when power is disconnected.

Maintenance
Service:
It is recommended to clean the device at least once a year. Sealing and valve elements are
subject to wear, which depends on various operating parameters such as pressure,
temperature, dirt content, etc.
For trouble free operation it is strongly recommended to change wearing parts every:
8000 operating hours of compressor
3 years in use regardless compressor operating hours
All parts that are subject to wear are packed in SERVIS KIT CDi 16-B.
Attention
Before beginning maintenance work take the drain out of operation, switch off the power
supply and depressurize the unit.
Service kits
Based on type of CDi-16B drain following servis kits can be used:
SERVIS KIT CDI 16-B 230V
SERVIS KIT CDI 16-B 115V
Servis procedure
Read complete installation and operating manual before beginning any maintenance or
service work.
Depressurize the unit, take the drain out of operation and switch off the power supply
Unscrew four screws (24) from drain housing and remove cover (2).
Remove worn components from the device and replace them with components you will
fint in SERVICE KIT.
Put che cover (2) back on and tighten it with four screws (24).
Before putting the device back to operation check for leackage and test proper
operating by pressing TEST button.
