used in new installations which have not been rinsed it may be necessary to check
and clean the regulator (nozzle seat, capsule and capsule holder) and the strainer.
You can check steam traps MK 25... for steam loss during operation by using the
ultrasonic measuring unit VAPOPHONE

or the test unit TRAP

Should you detect any loss of live steam clean the trap and/or replace regulator.
