GENERAL MAINTENANCE
The jacket of the water heater can be cleaned with a soft cloth and warm mild soapy water. Under no
circumstances should abrasive materials or powders be used.
The area around the water heater can be sprayed with insecticide to rid the area of insects. Insects encroaching
into or nesting in the water heater can interfere with the operation of the water heater and also damage
components.
Switch off the electrical supply at the power outlet to the water heater and only spray the insecticide when
the water heater is not operating.
Gases from many aerosol sprays are flammable, or may become corrosive when drawn into a flame.
Wait a few minutes to allow any aerosol gases to dissipate before switching on the electrical supply at the
power outlet to the water heater.
