Filling and commissioning the iStore Hot Water System
1.
Turn on the cold water supply to the tank and open a hot water tap preferably laundry tap without filter as
existing sediment may partially block pre-existing water saving devices.
2.
Leave tap open until all air is bled, then turn off hot water tap.
3. Activate PTR Valve (Pressure relief valve) to ensure system is fully bled of all air.
4.
Once the system is fully pressurised with water, thoroughly check all fittings, connections and pipework for
water leaks.
ATTENTION
: The PTR valve attached with the
unit must be installed, failure to do so will cause
damage to the unit, and possible personal injury.
Do not use stainless steel fittings to connect directly
with other metals to prevent galvanic corrosion.
