8.3.1 Owner Inspection
Water Pik Technologies recommends that you
inspect the heater on a continual basis and especially
after abnormal weather conditions. The following basic
guidelines are suggested for your inspection:
1. Keep the top and surrounding area of the heater
clear of all debris.
2. Keep the area around and beneath the heater
clean and free of all combustible materials such
as paper, leaves, etc.
3. Do not store or use gasoline or other flammable
vapors, liquids or chemicals in the vicinity of
this or any other appliance.
Ne pas entreposer ni utiliser d'essence ni d'autres
vapeurs ou liquides inflammables à proximité de
cet appareil ou de tout autre appareil.
4. Do not use the heater if any part has been under
water. Immediately call a qualified professional
technician to inspect the heater and replace any
part of the control system which has been
submerged.

l'eau, même partiellement. Faites inspecter
l'appareil par un technicien qualifié et remplacez
toute partie du système de contrôle et toute
commande qui ont été plongés dans l'eau.
5. If the heater is equipped with a pressure relief
valve, check for corrosion in and around the
valve. With the filter pump on, lift the release
lever on the top of the valve to make sure that
water runs freely through it. If corrosion is
found, replace the pressure relief valve. When
