CONNECTING THE ELECTRICAL SYSTEMS
The Solarstream is designed for single phase 230~240 V A.C. 50 Hz supply, max load 1400 watt. Australian Standard AS/
NZ 3000 or AS/NZ 3006 Wiring Code and local supply authority regulations apply.
The Heat Pump should be plugged into standard day rate power points, or alternatively arrangements may be made with an
electrician to have the power lead directly wired into an off-peak supply at the main circuit board. Allow for a 10 amp power
supply with circuit breaker.
The Solarstream does not have an electrical booster element.
The Solarstream is supplied with a thermostat on the side of the Water Tank, behind the upper cover, to regulate the water
temperature and a manual reset, over-temperature safety cut-out located on the side of the Heat Pump to protect the Heat
Pump; these devices regulate the water temperature. Under no circumstances, should the Solarstream be operated without
both of these devices being in circuit.
The wiring loom connection between the Heat Pump and the Water Tank is standard 3 metres in length, designed for
230~240 volt ac power. It is a 1.5 mm
2
cable, protected in UV resistant flexible conduit.
Fit the wiring loom through the cable hole in top inspection cover on the Water Tank and secure with the conduit gland
and lock nut. Ensure the conduit gland is tight so cable cannot pull out.
Heat Pump connection: Connect the screw down spade lugs to the heat pump thermostat connection terminal, and the
earth wire to the earth lug as in Fig A below.
Water Tank connection: Connect the push on connectors to the tank thermostat and the earth wire to the earth lug as in Fig B below.
It is recommended that cable ties be used to tie the wiring loom to the refrigerant lines.
Where refrigerant line extension kits are used (refer page 4) these kits are supplied with matching extension thermostat
wiring looms.
Never attempt to join or extend a Solarstream wiring loom.
Do not connect the thermostat directly to an external power outlet. The power source must be derived from the Heat Pump
via the wiring loom. Replacement of the wiring loom should be undertaken only by a qualified electrician or authorised
Solarstream service technician.
A wiring diagram is located inside the plastic side cover of the heat pump (a detailed wiring diagram is located under heat
pump lid for maintenance).
