DOES THE WATER QUALITY AFFECT THE WATER HEATER?
The water heater is suitable for most public water supplies, however some water qualities may have
detrimental effects on the cylinder, solar collectors and fittings. If you are in a known harsh water
area you must read page
conditions described on page
HOW LONG WILL THE WATER HEATER LAST?
There are a number of factors that will affect the length of service the water heater will provide. These
include the water quality, the water pressure, temperature (inlet and outlet) and the water usage
pattern. However, your water heater is supported by a comprehensive warranty
ANODE PROTECTION
The anode(s) installed in your water heater will slowly dissipate whilst protecting the cylinder. The life of
the water heater cylinder may be extended by arranging for an authorised person to inspect the
anode(s) and replacing it if required.
The suggested time after installation when the anode(s) should be inspected is 8 years.
For softened water supplies or in areas of poor water quality, it is recommended the anode be
inspected 3 years earlier than shown (refer to
BLEEDING THE SOLAR COLLECTORS
It is necessary to purge air from the collector circuit:
•
When the water heater is to be turned on and the solar collectors and solar hot and solar cold pipe
work have been drained.
•
After maintenance has been conducted on the pipe work and air has entered the system.
•
If the circulator appears not to be circulating water around the system.
Warning: Bleeding the solar collectors should be conducted in the morning, within three hours of
sunrise, when the water temperature inside the solar collectors is lower.
To purge air from the collector circuit:
•
Ensure the water heater is full of water and all of the hot
taps are turned off.
•
Using a flat blade screwdriver, open the bleed valve (if it
is not already open) fitted adjacent to the solar hot water
(from collector) inlet of the solar storage tank (see
diagram).
•
The mains pressure will force water to flow from the tank
and through the pipe work, expelling air from the collector
circuit through the bleed valve. This is evidenced by
spurting of water from the drain line connected to the
bleed valve.
Warning: Exercise care to avoid any splashing of
water, as water discharged from the solar collectors may
be of a very high temperature.
•
Close the bleed valve when water runs freely from the
drain line.
