EVT DD Solar Pre Heat System Operation and Installation Manual
BROKEN OR DAMAGED EVACUATED TUBES
Broken Evacuated Tubes
If any of the evacuated tubes have a clear or white bottom this may indicate that the
vacuum within the tube has gone and the tube will not be performing properly. The
tubes are normally a silver colour.
If the vacuum in the tube is gone or the tube is obviously broken, the system can
still be used. The remaining tubes will still 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.
WATER FLOW FLUCTUATIONS
High hot water usage
Higher than normal number of hot taps in use at the same time may cause a decrease
in the hot water flow from the taps.
WATER HAMMER
Hot and cold water
plumbing in the premises
Contact your installer or a plumber to discuss checking the clipping of hot and cold
water pipe work and install a pressure limiting valve or water hammer arrestor as
required.
