INSTALLATION INSTRUCTIONS - ALL MODELS
24
Plumbing
All plumbing work must be carried out by a qualified person. All installations are to be in accordance with national and
local codes and regulatory authority requirements applicable in your area. In Australia, this must also be in accordance
with Standards AS/NZS 3500.4 and all local codes and regulatory authority requirements. In New Zealand, the installation
must conform to Clauses G12 and H1 of the New Zealand Building Code.
Note that any pipes that are required to enter to the house either through a wall, ceiling cavity or roof need to be fully
sealed and waterproofed and should comply with local building codes and practices.
Warning: Plastic pipe work should not be used between this water heater and a temperature limiting device or a hot
water outlet if a temperature limiting device is not installed.
This water heater can produce water at a temperature and pressure which can exceed the performance limits of plastic pipe.
This may result in pipe work failure leading to severe water damage to the property. If plastic pipe is used as a hot water
pipe in the property, then a temperature limiting device must be installed between the water heater and this pipe work.
Note: The solar storage tank of a solar water heater should not be installed as part of a circulated hot water flow and return
system in a building. The benefits of solar gain will be significantly reduced. If a circulated flow and return system is
required, it is necessary to install a secondary water heater in the circulated flow and return system and supplied from the
solar water heater. The flow and return lines connect to the secondary water heater, not the solar storage tank.
This water heater is intended to be permanently connected to the water mains and not connected by a hose-set. A braided
flexible hose or semi-flexible connector may be used for connection to the water heater, where permitted by
AS/NZS 3500.4.
TEMPERATURE PRESSURE RELIEF VALVE
A combined temperature and pressure relief (TPR) valve (Part No. 451104) is to fitted to the connection end of the tank to
limit both the tank water pressure to 1000 kPa and the tank water temperature to 99°C. The temperature pressure relief
valve is supplied in the pipe kit. The temperature pressure relief valve must be fitted to the end of the hot water outlet Tee
before the water heater is operated, except where the storage tank is vented to atmosphere through an open pipe. Before
fitting the relief valve, make sure the probe has not been bent.
To fit the relief valve:
•
Seal the thread with an approved thread sealant such as Teflon tape - never hemp. Make sure tape does not hang over
the end of the thread.
•
Hand tighten the valve into the hot water outlet Tee (refer to
“Connection Details”
page 48).
•
Using a spanner engaged on the valve’s spanner flats and applying medium pressure to tighten, turn the relief valve an
additional ½ to 1 ½ turns to secure and make the joint water tight, leaving the valve drain pointing downwards
towards the rear of the storage tank and away from the electrical cover.
Warning: Do not use a pipe wrench or poor fitting tool on the valve body nor over tighten the valve, as this could
damage the valve and prevent safe operation.
•
Operate the easing lever on the valve to check the smooth operation of the valve plunger. It is very important the lever
is raised and lowered gently. The lever should move smoothly and without undue force.
•
If the lever cannot be moved or is jerky in its movement, then the valve has been damaged and must be replaced.
•
A copper drain line must be fitted to the temperature pressure relief valve (refer to "Relief Valve Drain" on page 25).
The drain line must not be installed in front of or prevent access to the electrical cover of the water heater.
•
The valve must be insulated with closed cell polymer insulation or similar (minimum thickness 9 mm) and the
insulation installed so as not to impede the operation of the valve.
The insulation must be weatherproof and UV resistant if exposed.
EXPANSION CONTROL VALVE
An RMC H50 Expansion Control Valve (part no 451103) is supplied in the pipe kit and Solahart recommend its fitment in
all instances. Install the expansion control valve using a brass Tee, brass union and brass nipple on the cold water line to
the water heater.
Local regulations may make it mandatory to install an expansion control valve in the cold water line to the water heater. In
other areas, an ECV is required if the saturation index is greater than +0.4. Refer to
“Saturation Index”
on page 17.
The expansion control valve must always be installed after the TRIO valve (part no 203701) or non-return valve and be the
last valve installed prior to the water heater. Refer to
“Cold Supply Line Valve Location”
and diagram on page 25. A
copper drain line must be fitted to the expansion control valve. Refer to "Relief Valve Drain" on page 25.
