“Commissioning” for further details.
2. Fluctuating or
reduced fl ow rate.
a. Check the Showerhead, Hose and Filters for any
blockage.

nominally equal and sufficient. Refer to section:
“Specifi cations” for further details.
c. Make sure the inlet temperature differentials are
sufficient. Refer to section: “Specifications” for
further details.
d. Flow Regulator fi tted incorrectly.
e. Airlock or partial blockage in pipework.
3. No fl ow from the
outlet.
a. Check the Showerhead, Hose and Filters for any

b. Signifi cant supply temperature fl uctuation.
c. Signifi cant supply pressure fl uctuation.
d. Faulty Thermostatic Cartridge. Renew.
5. Maximum blend
temperature
setting too hot or
too cold.
a. Indicates incorrect maximum temperature setting.
Refer to section: “Commissioning” for further
details.
