COMMERCIAL INSTALLATIONS:

Whilst there is no specific need for any external
weather protection for the Solarstream Heat
Pump Water Heater, if shelter is available such
as an overhanging eave, it is a good idea to
use it.

The Heat Pump unit is designed to be installed
outside. In cold conditions it will produce a
lot of condensate water from the evaporator.
This needs to drain away with out causing
any damage to the surrounding building or
material.

The location of the tank and Heat Pump is
flexible. Good design considerations should
be given to:

1. Position the water tank in close proximity
to bathroom and kitchen area to reduce
heat waste.

2. Minimise the distance between Water Tank
and Heat Pump unit for efficiency.

3. Position the Heat Pump unit to maximise
any sun, ambient warm or reflected heat
from wall or building.

Solarstream units can be single units or coupled together in many combinations from 3 to 6 units for energy
efficient light commercial installations.

Typical Commercial Examples Are:

Gymnasiums, Fitness Centres, Health Spas 
Aged Care Facilities, Medical Centres, Hair Salons 
Kindergartens, Day Care Centres, Play Centres 
Hostels, Backpackers, Motels Complexes, Caravan Parks 
Manufacturing Facilities, Commercial Buildings, Bars, Restaurants 

INSTALLATION RECOMMENDATIONS:

SECTION 1: PLUMBING INSTALLATION

It is recommended that hot­water 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
r

egulations.

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.
