Selecting A Location; Assembly; Hanging The Basin - Desert Spring DS-3200 Assembly & User Manual

1. Selecting a location

• This humidifier is to be mounted on the COLD AIR RETURN
(preferably on the narrow side) of a forced air heating system.
If the humidifier must be mounted on a plenum/duct which is over
12" wide or on non-metal duct, the plenum/duct must be reinforced and/or
the humidifier must be supported by other means.
• Ensure that there is sufficient clearance for the humidifier, water
supply, and air supply ductwork. If clearance problems exist with
utilities, qualified tradespeople should be called.
• Air is supplied to the humidifier with a 3' flexible duct connected to
the air take-off (with sliding damper) mounted on the HOT AIR
SUPPLY coming out of the furnace. (Check clearance to Air conditioner coil)
• Follow the instructions on the humidifier TEMPLATE (Page 7)to locate
and cut holes for the humidifier and take-off.
• Note that the top of the round take-off opening should be a minimum of
1" higher than the rectangular humidifier opening (max. 8'). Mount the take-off
so that the damper can be easily opened and closed.
2. Humidifier assembly
• Install the float into the slot in the side of the basin, ensuring that
the float seal is against the outside wall of the basin.
Hand tighten the float adjustment nut.

• Next install the cap. Optionally, connect a garden
ball valve and a length of garden hose which
extends to a floor drain, or an Auto Flush unit.
• The humidifier can be configured with either
a right or left air supply. This will depend
upon the layout of your furnace.*
