FM Environmental warrants, to the original user, that the Grease
Guardian main tank supplied and used in the service and in the
manner for which it is intended shall be free from defects in materials
and workmanship for a period of 10 YEARS. This Warranty is void
should the product be damaged by the customer prior to acceptance
or as a result of unreasonable use neglect, alteration, improper
installation, improper service, maintenance neglect, installation or
other causes not arising out of defects in material or workmanship.
The warranty is also void should any of the following conditions exist at any time prior to the defect
becoming apparent on the box:
• Salinity level exceeding 1000 ppm
• Chloride level exceeding 250ppm
• pH lower than 6 or greater than 9
• Chlorine levels (from the use of bleach detergents or similar) exceeding 2ppm
• Detergents poured directly into the tank or in high concentrations. The use of bleach (chlorine)
and aggressive chemicals when poured in sinks and fixtures discharging into the Grease
Guardian is to be limited, and the tank is to be flushed with running tap water for a minimum
duration of 5 minutes after these are used in the sinks so to dilute their effect. Detergents are
not to be poured directly into the tank.
• Venting not provided on the outlet pipe as per the instructions given, thus inhibiting the venting
out of any corrosive gases
• Sludge emptying, if not happening on a regular basis will allow for the accumulation of heavy
deposits at the bottom of the tank and these will create corrosion problems. The tank should be
emptied, cleaned from sludge and refilled with clean water every 3 months
• Water softeners and reverse osmosis system reject, if allowed to enter the tank will increase the
salinity levels of the water and induce corrosion. Reject waters of water softeners and reverse
osmosis units have to by-pass the unit and discharge in the discharge pipe after the outlet
• Daily normal water discharge into the unit should not be inhibited, where regular discharge of
water from sinks/fixtures should happen for a minimum of 5 minutes daily so as to avoid static
water conditions which in themselves might induce corrosion.
