SECTION 5: TROUBLE SHOOTING
HEAVILY MINERALISED WATER
Where a Solarstream is connected to a water supply from unfiltered or highly mineralised water sources such as a spring,
dam, bore, river or other natural ground sources, we require that the water be tested. Where water stored in the Water Tank
exceeds the following characteristics an issue with corrosion may occur and void the water tank warranty.
Total dissolved solids
600 mg/litre or parts per million
Total hardness
200 mg/litre or parts per million
Chloride
250 mg/litre or parts per million
Magnesium
10 mg/litre or parts per million
Sodium
150 mg/litre or parts per million
Electrical Conductivity
850 µS/cm (micro siemens per centimetre)
pH
Min 6.5 and Max 8.5
INSTALLERS AND SYSTEM CHECKS
Commissioning
Heat Pump unit is securely fastened to prevent tipping over.
Water Tank is totally secure and cannot tip over.
Water Tank is plumbed correctly, bled of air and full of water.
Pressure and temperature relief valve is working. (Perform a manual release test)
Refrigerant lines are mechanically protected against possible impact or damage.
All refrigerant gas lines are free of any kinks or twists.
All couplers and flare nuts are tight with no gas leaks. (Perform soapy water test)
All Tank and Heat Pump covers are back in place and tight.
Condensate water spilling from the Heat Pump outdoor unit will not cause any problems.
240V Power is connected and switched on at the socket outlet.
Unit is electrically earthed, copper pipe work is earth bonded.
Thermostat is connected:
230 ~ 240 V between neutral and terminal 1 (power to thermostat)
230 ~ 240 V between neutral and terminal 2 (power return from thermostat)
Refrigerant gas valves open on Heat Pump unit.
Check the Heat Pump continues to run for at least 20 minutes on first start up.
Warm water should be evident at hot taps in about 60 minutes.
Check firstly that the Heat Pump is connected to an electrical outlet and that power is available at the outlet by testing it with
another electrical product. If the Heat Pump is connected to the controlled water heater wiring, then your electricity supplier
may have the hot water supply switched off due to high demand or power load scheduling. You can check by calling your
electricity retailer.
Recheck hot water in several hours, it may just have been heavy usage, or a cool ambient temperature which has affected
hot water recovery performance.
The Solarstream seems to be operating for too long each day up to 4 hours at times under normal domestic family use?
It is likely that your refrigerant levels are too low, you may even have a slow gas leak. You will need to contact a Refrigeration
Mechanic and ask them to check for gas leakage and re-gas your unit. The gas charge in the whole Solarstream system
should be 1.5kg of R417A refrigerant. (1.34 kg Heat Pump, 130 g Water Tank, 30 g/2 mtr pair of Refrigerant Lines)
R417A is a special high performance, ozone friendly gas.

LOSS OF HOT WATER
WATER IS WARM BUT NOT HOT
MAINTENANCE
For optimal long term performance, we recommend that you periodically check the fin coils of the evaporator and remove
any material deposits restricting air flow with a brush or high pressure garden hose. Annually, we recommend operating the
Pressure and Temperature relief valve (located at the top of the tank near the hot water outlet) by gently raising and lowering
the lever. We recommend that you check with your plumber whether you need to drain and flush your tank periodically to
remove possible sediment build-up inside the tank, depending on your local water quality. If so, follow the plumber’s instructions.
