33-1197 Solahart Owner‟s Manual – Thermosiphon Systems - Revision H – Nov 2013 12 Electrical ELECTRICAL CONNECTION AND CODES All electrical work and permanent wiring must be carried out by a qualified person. All installations are to be in accordance with national and local electrical codes and regulatory authority requirements applicable in your area. In Australia, this must also be in accordance with the Wiring Rules AS/NZS 3000. ! WARNING: DO NOT TURN POWER ON UNTIL THE WATER HEATER IS FILLED WITH WATER OR DAMAGE TO THE HEATING ELEMENT WILL RESULT The power rating and current requirement of your Solahart water heater will be specified on the heater‟s data plate, located on the cover to the electrical cavity. The temperature rating of the power supply lead‟s insulation should suit this application. All electric wiring should be enclosed in suitable weatherproof conduit with watertight fittings. An isolation switch MUST be installed in the meter box for service work on the unit. The isolating switch should be left switched on. Leaving the isolating switch switched on will also provide a sufficient period of time each day for the booster heating unit to operate, if required, to satisfy the requirements of AS 3498. If water and/or power are not available on completion of installation, isolation switch in the meter box in the OFF position and place a warning label “Do not turn on electricity until filled with water” on the electrical isolation switch. Timer Control Switch A suitably rated timer control switch can be installed and will help maximise energy savings with an electrically boosted solar water heater connected to a continuous, time of use or extended Off-Peak (overnight and day) electricity supply. If used with an extended Off-Peak (overnight and day) electricity supply, the timer switch should: Be operated by a continuous power supply on its own circuit from the switchboard with the booster heating unit operated by the Off-Peak power supply. A double pole isolating switch is required to be installed at the switchboard to simultaneously isolate both circuits. Or Be of a type which has an internal rechargeable battery to keep time when the power supply is not available to the timer. Refer to “Programming the Timer” on page 5.
