3.1 Water Supply
Note: All water supply and drain line connections should be installed in accordance with local
plumbing codes, and/or national codes, whichever is more restrictive.
Before making the hydraulic connections, make sure the machine is disconnected from the power
supply.
The gaSteam can use water of virtually any quality, including demineralized water from a deionizer or
Reverse/Osmosis system. Generally, it is still advisable not to use water that has a high ability to cause
foaming, such as water containing high amounts of Phosphates, Nitrates, or softened. Softened water should
NOT be used in any case.
GaSteam 045: If the unit is attached to a water purification system that cannot produce more than 2.0 gal/min,
the existing internal fill valve (2.6 gal/min) must be replaced with the alternate 0.7 gal/min valve included with
the humidifier. Additionally, parameter b1 must be changed - see the section of this manual regarding
changing of controller parameters. Supply water flow must not be less than 0.7 gal/min
GaSteam 90: system must deliver 2.6 gal/min.
It is recommended that a 5 micron particulate filter be placed after the manual fill Valve 1 to trap solid
impurities, as shown below:
Connect the supply water and drain attachments as shown below.

IMPORTANT NOTE: Prior to starting the unit after installation, bleed the feed water lines for at least 30 minutes
before hooking up to the unit. This eliminates any contamination in the lines due to debris or sealing
compounds that could lead to foaming in the steam generator.
