The UBK 46 does not require any special maintenance. However, if used in new installations which have
not been rinsed it may be necessary to check and clean the trap.
You can check the trap for steam loss with GESTRA’s ultrasonic measuring unit VAPOPHONE ® or
the test unit TRAPTEST ® . The contact points required for this functional check are on the name plate
of the cover.
In case of steam loss clean the trap or replace the regulator.
