Never use abrasives or abrasive cleaning agents to clean this product. Clean regularly with
contamination free warm soapy water and a damp soft cloth.
Care and Cleaning:
If the system is supplied by a pressure pump, ensure that the pump can maintain 300kPa at the
cold Inlet. If not, install a low pressure cold feed and install the mixer as if for a low pressure
equal system.
If the Cold pressure is ABOVE 400kPa, install the mixer without modification (i.e. with red nozzle
as factory fitted.)
If the Cold pressure is BELOW 400kPa, replace the Red Nozzle with the Blue Nozzle supplied in
the carton.
a) To remove a nozzle from the mixer body fit a 6mm hex key into the hexagon outlet of the nozzle
and turn anti-clockwise until the nozzle comes free of the mixer body.
b) Fitting a nozzle is the reverse procedure to removal. The nozzle is in the correct position when
approximately 2mm of the nozzle protrudes from the outlet of the mixer. Do not use excessive
force when fitting the nozzle, it should turn freely. Screw in until just tight and then unscrew half a
turn.
