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 .

In addition to these operating instructions, local or national regulations must be complied

with, if necessary.

Make sure that the BEKOMAT® 31U 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.

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.

Safety instructions

BEKOMAT® 31U 5

Danger!

Supply voltage!

There is the risk of an electric shock involving injury or death when coming into contact

with non-insulated components carrying supply voltage.

Measures:

• During electric installations, all regulations in force need to be adhered to (e.g. VDE 0100 / IEC 60364).

• When the control unit is open, service and installation works must only be undertaken when the

system is deactivated.

• The removed control unit has no IP degree of protection.

• All types of electrical works must be carried out by authorised and qualified personnel only.

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 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 will only function when voltage is applied.

• Do not use the test button for permanent drainage.

• 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.

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

3 Proper use

• The BEKOMAT® 31U 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 is able to drain condensate under operating pressure from the plant components

virtually without compressed-air loss.

• For its function, the BEKOMAT® 31U 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 as a condensate drain alone cannot guarantee a defined compressed-air quality,

for this purpose, other additional technical devices are required.

• BEKOMAT® 31U is not suitable for use in plants carrying vacuum or atmospheric ambient pressure

or in ex-areas.

• The BEKOMAT® 31U must not be exposed to permanent direct solar or thermal radiation.

• The BEKOMAT® 31U must not be installed and operated in areas with an aggressive atmosphere.

• The BEKOMAT® 31U is not heatable and, therefore, not suitable for the use in areas where frost

is likely to occur.

• The BEKOMAT® 31U is not suitable for CO2 plants.
