5. OPERATING INSTRUCTIONS
5.1 Filling The Water Heater
Open all hot water taps. Open the isolating valve at the cold-water inlet and allow the storage tank
to fill until water flows through the system. Close each hot water tap after the air is expelled from
the inlet water line.
5.3 Water Quality
Your Solarstream has been manufactured to suit the water conditions of Australian reservoirs
fed by mountain water. Australia is the driest continent on Earth and is subject to extended
periods of drought which can cause water supplies to become mineralised. Because the stainless
steel storage tank of your Solarstream does not have a sacrificial anode inside, it is susceptible to
poor water quality and chlorine when heated to 60 degrees C. Please note that harsh water
supplies can have a detrimental effect on your Solarstream and its life expectancy. Also, if you
use a rain water supply for your Solarstream, this can be acidic and require pH balancing for long
life. Our warranty policy provides options for longer warranty and tank life (refer Section 13).
5.4 Water Quality Limits - Warranty Exclusion
NOTE: Your warranty will be void if your inlet water exceeds these limits (Refer Section 13)
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
Siddons Solarstream recommends the use of Tanamet filters in WA, SA and country areas where
chlorine is added to the water supply, and a pH balancing filter for rain water supply (refer S13.5).
Safety Notes
Note.1: This water heater is fitted with a thermostat and over-temperature power cut-out (both
incorporated into the digital controller). Under no circumstances should the water heater be
operated without both of these devices being in the circuit. Only a qualified technician or the
manufacturer should carry out replacement.
Note.2: If the supply cord is damaged, the technician must replace it in order to avoid hazard.
Caution: The water heater must be filled with water before turning on the electricity
4.13 Caution Regarding Drilling into the Casing
DO NOT DRILL ANY HOLES INTO THE STORAGE TANK CASING. IT MAY CAUSE DAMAGE
OR LEAKAGE TO THE STORAGE WATER TANK INSIDE AND VOID YOUR WARRANTY

5.2 Expelling Air from the Circulating Water Pump before Powering Up First Time
After the storage tank is full of water, keep all the hot water taps and isolating valve at the cold
water inlet to let the water flow out for a few minutes, then power up the unit (use the open
ON/ OFF button on the digital controller). If the heat pump continues operating for approximately
5 minutes, then it is functioning satisfactorily. Finally, close all the hot water taps.
If the heat pump stops operating within 5 minutes, then air is still likely to be trapped in the water
pipes. Power off the heat pump and open the hot water taps again for a few more minutes to let
the water flow out, then power up the unit again following the above process.
