Bosch BSS250E-2 Installation And User Manual page 19

WATER PRESSURE
Test incoming water pressure with a gauge. If the pressure exceeds 750kPa, an approved
pressure limiting valve is required.
Pressure limiting valves are not supplied with Water Heaters.
PUMP LIMITS
Head limit of 6 meters. A different model pump (available from Bosch) will be required to
maintain water flow through the solar collectors for heads greater than 6 metres.
ELECTRIC BOOSTER HEATING UNIT
The booster heating unit provides boosted hot water during periods of low solar gain or high
hot water use. The recommended installation is for the electric element to be connected to a
continuous electrical tariff. Other configurations of wiring the booster element are not
recommended and may affect overall system performance and will not be covered by the
warranty.
SADDLING – PIPE WORK
To prevent damage to the cylinder when attaching pipe clips or saddles to the water heater
jacket, we recommend the use of self-drilling screws with a maximum length of 12mm. Should
pre drilling be required extreme caution must be observed when penetrating the jacket of the
water heater.
Note: Damage to the cylinder as a result of saddling to the jacket will void the warranty.
