2 Safety instructions
Please check whether or not these instructions correspond to the device type.
Adhere to all advice given in these operating instructions. They include essential information
which must be observed during the installation, operation and maintenance. Therefore it is
imperative for the service technician and the responsible operator / technical staff to read
these operating instructions prior to installation, start-up and maintenance.
The operating instructions must be accessible at any time at the place of application
of the BEKOMAT® 31U IF .
In addition to these operating instructions, local or national regulations must be complied
with, if necessary.
Make sure that the BEKOMAT® 31U IF is operated only within the permissible limit values
indicated on the type plate. Any deviation involves a risk for persons and materials, and
may result in malfunction and service failures.
If you have any queries regarding these installation- and operating instructions, please
contact BEKO TECHNOLOGIES GMBH.

Safety instructions
BEKOMAT® 31U IF built-in F 5
Danger!
Compressed air!
Risk of serious injury or death through contact with quickly or suddenly escaping
compressed air or through bursting plant components or plant components which
are not secured.
Measures:
• Do not exceed the maximum operating pressure (see type plate).
• Only carry out service measures when the system is pressureless.
• Use pressure-resistant installation material only.
• The feed pipe must be tubed firmly.
Discharge pipe: short, fixed pressure hose onto pressure-resistant pipe.
• Make sure that persons or objects cannot be hit by condensate or escaping compressed air.
Further safety instructions:
• For installation and operation, the national regulations and safety codes in force
must also be adhered to.
• Do not use the BEKOMAT® 31U IF in hazardous areas.
• Regarding the inlet screw joints, excessive tightening forces must be avoided.
This applies in particular to conical screw joints.
• The BEKOMAT® 31U IF will only function when voltage is applied.
• Use genuine spare parts only. This is imperative to ensure perfect functioning.
Additional advice:
• The removed control unit has no IP degree of protection.
• During installation, use spanner flat at the feed pipe (wrenchsize SW27) as a back rest.
• The service unit must not be dismantled.
Caution!
Malfunction during operation!
Through incorrect installation and poor maintenance, malfunction may occur at the
BEKOMAT® .
Condensate which is not discharged may cause damage to plants and in production
processes.
r
Measures:
• Condensate drainage which is reliable in performance directly optimises the compressed-air quality.
• To prevent damage and breakdowns, it is imperative to observe the following:
• Exact compliance with the specifications of use and with the performance parameters of
the BEKOMAT®, in connection with the case of application (see "Proper use" section)
• Exact compliance with the installation- and operation instructions in this manual
• Regular maintenance and control of the BEKOMAT® in accordance with the instructions
in this operating manual

Proper use
6 BEKOMAT® 31U IF built-in F
3 Proper use
• The BEKOMAT® 31U IF built-in F is an electronically level-controlled condensate drain for
compressed-air plants.
• The device is employed within the permissible performance parameters (see "Technical data").
• The BEKOMAT® 31U IF built-in F is able to drain condensate under operating pressure from
the plant components virtually without compressed-air loss.
• For its function, the BEKOMAT® 31U IF built-in F requires a supply voltage and an operating pressure
(see "Technical data").
• As far as the employment in plants with increased demands on compressed air is concerned
(food industry, medical technology, laboratory equipment, special processes etc.), the operator
must decide on measures for the monitoring of the compressed-air quality. These have an effect
on the safety of the subsequent processes and may prevent damage to persons and plants.
• It is the task of the operator to ensure that the indicated conditions are met during the entire
operating time.
4 Exclusion from the scope of application
• The BEKOMAT® 31U IF built-in F as a condensate drain alone cannot guarantee a defined
compressed-air quality, for this purpose, other additional technical devices are required.
• BEKOMAT® 31U IF built-in F is not suitable for use in plants carrying vacuum or atmospheric
ambient pressure or in ex-areas.
• The BEKOMAT® 31U IF built-in F must not be exposed to permanent direct solar or thermal radiation.
• The BEKOMAT® 31U IF built-in F must not be installed and operated in areas with an aggressive
atmosphere.
• The BEKOMAT® 31U IF built-in F is not heatable and, therefore, not suitable for the use in areas
where frost is likely to occur.
• The BEKOMAT® 31U IF built-in F is not suitable for CO2 plants.

Function
BEKOMAT® 31U IF built-in F 9
8 Function
Via the inlet line (1) the condensate flows into the
BEKOMAT® 31U IF and accumulates in the housing
(2).
A capacitively functioning sensor (3) continuously
registers the filling level and releases a signal to
the electronic interface (output Sen), as soon as
the container is filled.
(See also Chapter "Electrical installation")
The pilot valve (4) is triggered by an external signal
(input Drn). When this signal is available, the valve
is activated and the membrane (5) opens the outlet
line (6) to discharge the condensate.
With the reset of the signal, the outlet line is reclosed
tightly.

Pressure differences!
Each condensate accumulation point must be drained
separately.
Continuous slope!
Avoid a water pocket when installing the feed pipe
Deflector area!
If drainage is to be carried out directly from the pipe,
deflection of the air flow will be useful.
Ventilation!
If the slope in the inlet line is not sufficient or if any
other inflow problems occur, a venting line needs to
be installed.
