Before Servicing a Solar water heater
Working on roofs should always be considered a hazardous activity,
particularly early in the morning, late in the evening or after periods of rain.
Safety precautions pertaining to working on roofs are outlined in the Work
Cover Code of Practice “Safe work on roofs” Part 1 and 2 and in the
Occupational Health and Safety Act 1983.
Water under pressure and at temperatures up to 150ºC may be present in
the collector/s. Isolate water supply and relieve pressure through a hot tap
or the temperature and pressure relief valve prior to opening the collector
pipe work. Wear protective clothing to prevent scalding or burns.
Certain diagnostic procedures outlined in these service instructions
require “live” testing to be conducted. Caution should always be exercised
when conducting these tests to prevent the risk of electric shock.
