8. Maintenance 

FAR eye showers must undergo a function test at least once a month. This is set down in 

regulation BGI/GUV-I 850-0 of the BG Chemie. To do this, activate the shower for approx.  

5 seconds. This ensures not only that correct function is tested but that any standing water  

in the shower is replaced by fresh water (protection against microbial contamination).

As part of this function test, the shower should be checked visually for signs of wear and tear 

and any possible leaks and dirt such as e.g. dust or scale deposits. Inspect the hose for any 

twisted, bent or otherwise damaged places. Faulty parts must be replaced immediately.

9. Procedure for leaking hand-held eye showers

After connecting to the cold water system, the hand-held eye shower may have started to 

leak. This is generally due to dirt from the water supply which collects in front of the valve.  

If this has happened, disconnect the handheld eye shower from the supply. Operate the 

shower a few times without pressure and rinse the pipe thoroughly before reconnecting. If the 

fault cannot be remedied by this means the enclosed mesh filter must be fitted in front of the 

stainless steel hose.
