4.6 Cold Water Connection
Between the water supply main and the 3/4 inch BSP socket connection to the storage tank inlet
in the water heater, you must fit an approved Pressure Limiting Valve set at 500kPa water
pressure, an isolating valve, a non-return valve, a line strainer (optional but recommended), and
a union fitting. All fittings must be approved by the relevant Authority as per the following diagram.
4.5 Expansion Control Valve (ECV)
An Expansion Control Valve (ECV) must be fitted in WA, SA, NT and most country areas. Check
with your Plumber. This type of water is referred to as hard or scaling water because calcium
carbonate is deposited out of the water onto any hot metallic surface. The ECV should be set at
700kPa, 150 kPa lower than the PTR valve. The ECV should be fitted onto the cold water supply
line between the non-return valve and the water storage tank. We recommend the installation of
an ECV, even if it is not required, for additional safety and to reduce PTR valve hot water wastage.
4.4 Pressure & Temperature Relief Valve (PTR)
The Pressure and Temperature Relief (PTR) valve, supplied with the unit is rated at 850 kPa
pressure and must be fitted
remove the water discharged during the normal heating cycle. The valve
thread is 1/2 inch BSP.WARNING: A separate drain line must be run for this PTR valve. It is not
permitted to couple the drain lines from the PTR valve and evaporator into a single common line.
However, the use of a Tundish under the evaporator drain connected to the drain of the PTR
valve is acceptable.
Following installation
MAINTENANCE FOLLOWING INSTALLATION: The PTR valve lever must be operated AT
LEAST ONCE PER YEAR to ensure that the water-ways are clear and to remove naturally
occurring mineral deposits that may adhere to the valve, causing it to leak or rendering it
inoperative. When manually operating the lever, 60 deg C hot water will discharge so be careful
not to touch the PTR water outlet to avoid scalding. BEFORE operating the lever, check to see
that a discharge line is connected to this valve directing the flow of hot water from the valve to
a drain. If no water flows, the PTR valve is inoperative. TURN OFF THE WATER HEATER AND
CALL A PLUMBER IMMEDIATELY. This PTR valve is designed for emergency safety relief only.
to the top front socket and made accessible so that the release
mechanism can be operated and, if required, replaced. The outlet of the PTR valve must be
suitably drained to
