Plumbing
To make the necessary connections for water fill and drain, the
following steps are required. (Refer to Figure 4 for locations)
1. Install external shutoff valve between the water supply and
the humidifier for ease in servicing the unit.
2.
Connect water supply to the 1/4” compression fitting on the
bottom of the cabinet.
3. Connect the 3/4” tube from the accessory pack to the drain
reservoir. Cut the tube to the length necessary to reach the
drain.
4. Insert the other end of the tube into a minimum 6” vertical
length of the 1-1/4” minimum I.D. drain line. The balance of
the drain line should be 1” I.D. minimum with a minimum
1/8” per foot slope. (See Figure 4.)
SECTION III INSTALLATION INSTRUCTIONS
Mounting
The cabinet is designed to safely contain the working components
of the HERRMIDIFIER 6500 series humidifier and dissipate
heat to protect the electronics. Locate humidifier, steam pipe
and accessories in a manner to allow routine inspection and any
necessary maintenance. DO NOT install the unit above false
ceilings or around valuable property, where a malfunction could
cause damage. Correct positioning of the humidifier is important
to allow for proper operation and easy maintenance. Minimum
clearance around the cabinet should be maintained as follows:
Minimum Clearances

6”
Right
12”
Top
6”
Bottom

1. Remove cover by removing four side screws.
2. Remove foam packing from top of cylinder.
3. Two 5/16” lag bolts are supplied with the CFS20/22 unit.
Install the lag bolts according to the dimensions in Figure 3.
4. Hang the unit on the wall and secure the bolts. Be sure the
unit is level and mounted directly to the wall into wood studs
at least 2” thick (or equivalent). Operating weight is 27 lbs.
5. Replace cover and four screws.

WARNING!
Do not mount any controls inside the unit or tap power
from any location in the unit, except as stated in these

CAUTION!
Do not use reverse osmosis or demineralized water
treatment without first consulting the factory. This
water may not be sufficiently conductive to allow proper
operation. Consult factory if water is outside the range
of allowable conductivities (125-1250 micro-Siemens).
Do not use hot water.

WARNING!
If the drain line is exposed, it is recommended that it be
insulated for safety. Do not use PVC drain line unless
“Drain Tempering” is enabled.
NOTE: Inlet water pressure must be in the range of
20-100 psig. Consult the factory if you are outside this
range. Softened water may be used but requires that
the low drain threshold be adjusted.
