Plate Collectors
If any of the evacuated tubes have a clear or white bottom this may indicate that the
vacuum in the glass tube has gone, and the tube will not be performing properly� The
tubes are normally a silver colour�
If the vacuum in the tubes is gone or the tube is obviously broken, the system can
still be used� The remaining tubes will be fully operational� However the system
performance will be reduced�
If a tube is broken or damaged it should be replaced� Contact Rinnai to discuss�

solar collectors
There is a small amount of ventilation between atmosphere and the internals of the
solar collector to ensure e󰀩cient operation. Under certain weather conditions, water
vapour naturally present in the air may condense on the inside surface of the collector
glass. This does not a󰀨ect the performance of the system. If you are concerned contact
Rinnai to discuss�
NOISYSOLARCOLLECTORS
Noise from solar collectors Occasionally on days of high solar gain, the water temperature in the collector may
become very high� The noise may be similar to a boiling kettle, or an expanding
contracting metallic sound� The collector is designed to withstand these conditions, and
no action is needed, unless it is extreme� Contact Rinnai to discuss if you have any
concerns�
