foreign material in the water supply. This will restrict the
flow of water and may affect heater operation and prolong
filling time. To inspect the strainer, close the cold water supply
valve ahead of the heater, disconnect the S-bend from the
inlet of the water valve and remove strainer from inlet. Clean
if required, replace strainer in inlet to the water valve,
reconnect S-bend and turn on water supply.
