Geyser-RO Maintenance
The Geyser-RO requires very little maintenance however to ensure long trouble free use, these items
should be checked periodically.
Air filter: The air filter on the back of the unit should be cleaned whenever it is visibly dirty. The
filter can be cleaned by simply hand washing in water. Replacement filters may be purchased from
Hubbell Electric Heater Company.
Evaporator: the evaporator underneath the filter can become clogged or dirty. It may be cleaned by
vacuuming or by a service provider and professionally cleaned. Do not use solvents containing bleach,
acetone, or flammable substances. Turn the unit off at the breaker before cleaning.
Drain and flush the water heater: Draining the tank every six months will help to ensure that sediment
does not build up in the tank and get into the Geyser-RO. Follow the directions from the tank
manufacturer for draining the tank.
Turning off / Storage of the Geyser: When the Geyser is turned off (for example in a vacation home)
and/or disconnected and stored (for example in a garage), very likely there will be water left in the
internal piping and components. Make sure to either store it in a place that will never freeze or blow the
water out of the unit if there is any chance of freezing temperatures. This will prevent the water from
freezing and splitting the pipes and components.
