ABOUT YOUR WATER HEATER

SAFETY
This water heater is supplied with temperature sensors, a pressure relief valve and a combination
temperature pressure relief valve. These devices must not be tampered with or removed. The water
heater must not be operated unless each of these devices is fitted and is in working order.
If the power supply cord or plug to the solar storage tank is damaged, it must be replaced by an
authorised person in order to avoid a hazard. The power supply cord and plug must be replaced with a
genuine replacement part available from Solahart. Phone your nearest Solahart Dealer to arrange for
an inspection.
The warranty can become void if relief valves or other safety devices are tampered with or if the
installation is not in accordance with these instructions.
TO TURN OFF THE WATER HEATER
If you plan to be away from home for a few nights, we suggest you leave the water heater switched on.
If it is necessary to turn off the water heater:
•
Switch off the electrical supply at the power outlet to the solar storage tank.
•
Close the cold water isolation valve at the inlet to the water heater.
TO TURN ON THE WATER HEATER
•
Open the cold water isolation valve fully at the inlet to the water heater.
•
Open all of the hot water taps in the house (don’t forget the shower).
Air will be forced out of the taps.
•
Close each tap as water flows freely from it.
•
Plug in the water heater at the power outlet and switch on the electrical supply.
The power outlet must be switched on for the solar controls to operate and solar gain to be
achieved.
HOW DO I KNOW IF THE WATER HEATER IS INSTALLED CORRECTLY?
Installation requirements are
shown on page
21. The water heater must be installed by an authorised
person and the installation must comply with National Standards AS/NZS 3500.4, AS/NZS 3000 and all
local codes and regulatory authority requirements. In New Zealand, the installation must conform with
the New Zealand Building Code.
Temperature controllers
must not
be fitted to the in-series booster water heater (refer to
warning
under
“How Hot Should The Water Be?”
on page 5).
PIPE WORK AND INSULATION
The solar hot and solar cold pipe work between the solar storage tank and the solar collectors and
between the solar storage tank and in-series water heater
MUST BE
of copper and fully insulated with
closed cell polymer insulation or similar (minimum thickness 13 mm). The insulation must be
weatherproof and UV resistant if exposed. The insulation will offer corrosion protection to a metal roof
against water runoff over the copper pipe, assist in avoiding accidental contact with the solar pipe work
and also reduce pipe heat losses.
The insulation must be fitted up to the connections on both the solar collectors and the solar storage
tank, as very high temperature closed circuit fluid can flow from the solar collectors to the solar storage
tank under certain conditions.
There must be a continuous fall in the pipe work from the solar collectors to the solar storage tank. The
continuous fall is essential to assist in the drain back function of the solar system.
