Correcting Excessive Water Flow from the Bubbler
Excessive water flow from the Bubbler outlet nozzle may be due to excessive
inlet water pressure. If inlet supply pressure is greater than 700 kPa, a pressure
limiting valve (PLV) should be fitted as per the manufacturer’s instructions (only for
EconoMaster/SiteMaster. The ChillMaster already has a PLV internally fitted).
If excessive water flow is still a problem, tighten the Cartridge inside the Bubbler, as
follows:
1. Turn off the water supply and use an adjustable shifter to remove the Cartridge
Locking Ring Cover from around the Bubbler Operating Button (Fig.3).
2. Remove the button to expose the Water Flow Adjustment Screw (Fig.4). Use a
small, flat screwdriver to remove this screw (Fig.5).
3. Using a small, flat screwdriver, remove the Water Flow Control Spring (Fig.6).
Inside the Spring Cavity is the Cartridge Assembly Fixing Nut.
4. Using a flat screwdriver, with a 7-8mm wide blade free of wear that fits freely
inside the Spring cavity, fully tighten the Cartridge Assembly Fixing Nut by
turning clockwise (Fig.7).
Note:
It is important not to use a flat screwdriver with a narrower blade than
recommended in Step 4, as this may damage the slot in the Cartridge Assembly
Fixing Nut and make future adjustment impossible. Do not force a screwdriver that
is wider than the Spring cavity into the cartridge, otherwise the cartridge may be
damaged and may malfunction.
5. Return the Spring and refit the Water Flow Adjusting Screw, using the flat of
your thumb before using the screwdriver to help prevent cross-threading of
the delicate plastic thread.
6. Turn ‘ON’ the water supply and adjust the Water Flow Adjusting Screw until
the desired water flow is achieved. Refit the Operating Button and then the
Cartridge Locking Ring Cover.
If water starts to come out of the bubbler outlet nozzle when refitting the Cartridge
Locking Ring Cover, repeat the above process, ensuring that the Cartridge
Assembly Fixing Nut is fully screwed in. If water outflow persists, the Cartridge may
need to be replaced. Contact Zenith Service.
