Summary of Water Chemistry Advice Affecting Warranty
The water heater, solar collectors and their components are not suitable for certain water chemistries. Those chemistries are
listed below. If the water heater is connected at any time to a water supply with the following water chemistry, the Solahart
warranty will not cover any resultant faults on the components listed below:
Water Chemistry Component
Total Dissolved Solids (TDS) > 2500 mg/L water heater cylinder
Total Dissolved Solids (TDS) not suitable for anode type water heater cylinder
Saturation Index (SI) < -1.0 solar collector
copper sheathed heating unit
Saturation Index (SI) > +0.4
(if an expansion control valve is not fitted) water heater cylinder
temperature pressure relief valve
Saturation Index (SI) > +0.8 solar collector
standard watts density heating unit
MAINTENANCE REQUIREMENTS
Collector Care
Ensure the glass on your solar collectors is free of dust, salt spray or any other matter which may reduce the effectiveness
of the solar collectors. Rainfall should keep the collector adequately clean. It is recommended that the collector glass be
washed clean at least every three months should adequate rain not have fallen in this period. Collector glass can be hosed
down or if the solar collectors are accessible, wash the collector glass with water and a soft brush when the solar collectors
are cool, such as early in the morning. In extremely dusty areas, such as mining towns and locations adjacent to dust
forming plants, extra attention should be given to this matter.
Have any trees trimmed which may shade the solar collectors.
Minor Maintenance Every Six Months
It is recommended minor maintenance be performed every six (6) months. Minor maintenance can be performed by the
dwelling occupant.
The minor maintenance includes:
1. If readily and safely accessible, operate the easing lever on the temperature pressure relief valve. It is very important
the lever is raised and lowered gently. Refer to
“Relief Valves”
on page 7.
Warning: Exercise care to avoid any splashing of water, as water discharged from the drain line will be hot.
Stand clear of the drain line’s point of discharge when operating the valve’s lever.
If the temperature pressure relief valve is not readily and safely accessible, contact your local Solahart Dealer. Do not
attempt to climb onto a non-trafficable roof to operate the relief valve lever.
2. If readily and safely accessible, operate the easing lever on the expansion control valve. It is very important the
lever is raised and lowered gently. Refer to
“Relief Valves”
on page 7.
If the expansion control valve is not readily and safely accessible, contact your local Solahart Dealer. Do not attempt
to climb onto a non-trafficable roof to operate the relief valve lever.
