SYSTEM REQUIREMENTS
The Geyser-RO should only be installed in a dry/covered location. The Geyser-RO is not designed to
be installed outside where it can be exposed to adverse weather conditions. The ambient air
temperature in the installation area should not drop below 50°F (10°C). The space where the
Geyser-RO is located needs to be 1,000 cubic feet or greater for proper air flow and to avoid
excessive cooling of the area. The Geyser-RO can be installed in attics, garages, or basements
provided the above criteria are met for proper installation.
The Geyser-RO connects to a typical household outlet, 115 VAC and 15 A. While the device requires
approximately 12 Amps momentarily upon power-up, the device draws 5-8 Amps during normal
operation. It is recommended that a dedicated 15 A Circuit be used to power the Geyser-RO. The
Geyser-RO is recommended for installation on storage tanks of 40 gallons (151.4 liters) or greater.
A drain must be available to accommodate condensate generated during operation of the Geyser-
RO. In high humidity environments, the Geyser-RO is capable of generating as much as 50 pints (24
liters) per day. The condensate can be routed to a floor drain, sink, the house waste line, or to the
outside by way of the drain hose (provided).
Check with the codes in your area for the proper way to dispose of the condensate. A condensate
pump may be required (not included).
The Geyser-RO will remove moisture from the air. It is an efficient dehumidifier and many have
found that the unit provides all the necessary dehumidification for the space the Geyser-RO is
located.
Moisture may occasionally cause frost to form on the evaporator. When frost builds up, the
Geyser-RO will go into a defrost cycle. This could occur as often as every two hours in a cold, humid
environment. While in defrost mode the fan will continue to run until the frost is removed from the
coil.
The Geyser-RO does not have any source of backup heat due to the external temperature
controller. In the event of a spike in domestic hot water (DHW) demand or failure within the
Geyser-RO there will be no source to provide back-up heat. In this circumstance, turn the Geyser-
RO off and turn the original source of heating on. Call your service technician for more information.
The Johnson A419 Series Electronic Temperature Control is supplied with 6 ft of wire to the bulb
sensor. Make sure the Geyser-RO can be installed within 6 ft of your existing water tank. Longer
sensor bulb wire is available up to 15 ft.
If you are retrofitting a boiler mate with the Geyser-RO call Hubbell Electric Heater Company
(203-378-2659) to make sure you have the proper diptube assembly for installation.
