SECTION 1: PLUMBING INSTALLATION
It is recommended that hot-
water outlet pipes are fully
insulated with weather proof
insulation such as Armaflex.
The hot-water outlet pipe
should be angled down at
about 15
0
minimum for the
first 250mm after exiting
from the Water Tank outlet.
This will create a heat trap
that will avoid any thermal
siphoning from the Water
Tank.
A drain must be included to allow full and
complete draining of the Water Tank
A licensed plumber should install the Solarstream. It is the installers responsibility to comply with all AS/NZ Standards, Building
Codes and Trade Codes of Practice for compliant installations of domestic hot water heaters. In Australia, your plumber should
also hold a Restricted Split System Air Conditioning Installation and Decommissioning License (Certificate II course under the
Australian Refrigeration Council’s code RSS03) covering air conditioning and heat pump split systems.
WATER TANK INSTALLATION
As the Solarstream does not require a sacrificial anode, the headroom above the cylinder only needs to accommodate
convenient installation rather than the one metre or more required to remove/replace the anode. Therefore, the Solarstream
water tank can be comfortably installed inside or outside of your house in a tight space with little headroom, although the
Heat Pump unit should be installed outside.
It is best to install the Water Tank close to the outlet that has the greatest usage of hot-water, such as the laundry or
bathroom. Ensure adequate access for service to the Thermostat and Pressure and Temperature (P&T) relief valve. Ensure
the specification label is visible. Installation must comply with Australian Standard AS/NZS 3500.4 and any local authority
regulations.
OUTDOOR
For outdoor (external) installations, a plinth or concrete base pad is recommended in accordance
with Australian Standard AS/NZS3500.4 to properly support the Solarstream water tank such that the
water tank is assured of remaining in a vertical position throughout its usable life and not lean over
due to possible erosion of soil under the plinth, or such risk.
SIESMIC RESTRAINT
Some building codes require Seismic Restraint of storage water heaters to be adequately supported against earthquake
forces. You should consider restraining the tank to a wall with Stainless Steel bands.
FILLING
Fill the Water Tank by opening all hot-water taps and opening the cold-water inlet to allow air in the system to be expelled.
Close each hot-water tap; as the flow becomes free of air, check all pipes for any signs of leaks. Power should not be turned
on until the Water Tank is completely filled with water.

Notes:
327SSAD model has a ring main return
port just above mid tank. This should be blocked
off with a 3/4 BSP plug.
Water control valves are not supplied with the
Solarstream unit.
