WATER FILTER
The Rheem Boiling Water Unit incorporates an integral water filter. The water filter
improves the quality of water by filtering odours and particles. Over time the water
filter could become blocked with particles. Rheem recommends that the water filter
be changed at least every 12 months. The boiling water unit controller has an
*electronic filter counter that lets the operator know when the filter is getting close to
its recommended life. (*If activated by installer)
IMPORTANT
Rheem highly recommends that regular water filter cartridge changes are carried out
to ensure the system is performing to a high standard. If the water filter is not
regularly serviced and maintained on the recommended intervals, the water filter
cartridge can block with the trapped impurities, causing bacterial growth in the filter
media and dramatically reducing filtered water flow, affecting the operation of the
filtered boiling water unit.
