DAILY: 

•  Check whether the dew point indicated on the electronics is correct. 
•  Ensure that the condensate drain system functions properly. 
•  Make sure that the condenser is clean. 

 

EVERY 200 HOURS OR MONTHLY

 

 

  

 

•  Clean the condenser using an air jet (max. 2 bar / 30 psig) inside out. Make 

sure not to damage the aluminium lamellae of the cooling package. 

•  Finally, verify the operation of the device. 

 

EVERY 1,000 HOURS OR ANNUALLY  

•  Verify all screws, clamps and connections of the electric system to make sure that they are fastened 

securely. Check the device for broken and ruptured cables or cables without insulation. 

•  Check the refrigeration cycle for signs of oil and refrigerant leaks.

 

•  Measure the current strength and note it down. Ensure that the read values are within the permissible 

limit values, as indicated in the specification table.

 

•  Check the hose lines of the condensate drain and replace them, if required. 

 

• 

Finally, verify the operation of the device. 

 

EVERY YEAR 

•  Clean housing and valve of BEKOMAT 
•  Replace BEKOMAT wearing parts 

12.2  Troubleshooting  

 

Certified skilled personnel  

Installation works must exclusively be carried out by authorised and qualified skilled personnel. Prior to 
undertaking  any  measures  on  the  DRYPOINT®  RS  15-550  HP50  NA  high  pressure  compressed-air 
refrigeration  dryer,  the  certified  skilled  personnel  shall  read  up  on  the  device  by  carefully  studying  the 
operating instructions. The operator is responsible for the adherence to these provisions. The respective 
directives in force apply to the qualification and expertise of the certified skilled personnel. 
For safe operation, the device must only be installed and operated in accordance with the indications in 
the  operating  instructions.  In  addition,  the  national  and  operational  statutory  provisions  and  safety 
regulations, as well as the accident prevention regulations required for the respective case of application, 
need to be observed during employment. This applies accordingly when accessories are used.

  

 

Danger! 

Compressed air! 

Risk of serious injury or death through contact with quickly or suddenly escaping compressed 
air or through bursting and/or unsecured plant components. 

 

Compressed air is a highly dangerous energy source. 
Never work on the dryer when the system is under pressure. 
Never direct the compressed-air outlet or condensate drain hoses at persons. 
The user is responsible for the proper maintenance of the dryer. Non-observance of the instructions in the 
"Installation"  and  "Maintenance,  troubleshooting,  spare  parts  and  dismantling"  chapters  leads  to  the 
expiration of the guarantee. Improper maintenance may result in dangerous situations for the personnel 
and/or the device. 

 

Danger! 

Supply voltage! 

Contact with non-insulated parts carrying supply voltage involves the risk of an electric shock resulting in 
injuries and death. 

 

Only qualified and skilled personnel are authorised to run electrically-operated devices. Prior to undertaking 
maintenance measures at the device, the following requirements must be met: 

Make sure that the power supply is switched off and that the device is off and marked for maintenance 
measures. Please also ensure that the power supply cannot be re-established during the works.
