Herrmersion RE
Installation, Operation, & Maintenance Manual
WARNING
Never service any component without rst disconnecting all
electrical supplies to the unit or severe personal injury or
death could occur.
CAUTION
Insure that all power sources conform to the unit requirements
or damage to the unit may result.
These units have been designed for any tap, softened, de-
ionized (DI) or reverse osmosis (RO) water applications.
With tap/softened water, an adjustable drain cycle and
skimmer cycle are provided to automatically drain away
some water contaminants; reducing cleaning intervals. For
DI/RO water, the system is virtually maintenance free. The
skimming cycle may be deactivated via the keypad.
Follow installation instructions CAREFULLY to avoid creating
unsafe conditions. All electrical wiring should be done and
checked by a qualied electrician using copper conductors
only. All piping connections should be made and leak-tested
by a qualied service technician, per instructions in this
manual.
Make certain that the power source conforms with to the
electrical requirements of the unit. Disconnect power before
installing or servicing the unit. If power disconnect is out of
visual sight, lock it into open position and tag it to prevent
unexpected application of power. Failure to do so could
result in fatal electrical shock.
WARNING
Do not depend upon a unit control switch or other switch as
the sole means of disconnecting power when installing or
servicing the unit. Always disconnect power at main circuit
breaker. Failure to do so could result in fatal electrical shock.
Special attention should be given to grounding this unit. To
prevent the risk of electrocution, the unit must be securely
and adequately grounded. This should be accomplished by
connecting a grounded conductor from the service panel to
the grounding lug located inside the control section of the
unit. To ensure proper ground, a qualied eld technician
must test the grounding means.
Do not defeat safety interlocks, such as the high temperature
limit or door switch. Do not attempt to operate the unit without
the doors installed.
In cases in which property damage may result from
malfunction of this unit, a backup system should be used.
INSTALLATION
WARNING
Open all disconnect switches and secure in that position
before installing unit. Failure to do so may result in personal
injury or death from electrical shock.
UNIT LOCATION & MOUNTING
The Herrmersion – RE unit is designed to be mounted on a
wall and should be located as close to the dispersion means
as possible (i.e. close to the duct being served with the
steam). This will minimize energy losses.
The unit requires electrical and plumbing connections and
should be mounted in such a way to facilitate access to these
connections.
In order for the magnetic water level switches and the
skimmer function to operate properly, the unit must be
mounted level and plumb with reference to the front and top
of the unit.
The cabinet is designed to safely dissipate heat to protect
the electronics. Herrmersion – RE humidiers, steam piping
and any other accessories should be located in a manner to
facilitate routine inspection and any necessary maintenance.
The unit should not be located above (false ceilings) or
around valuable property where a malfunction could cause
damage. Minimum clearance around the cabinet must be
maintained.
Minimum Access Requirements
Left 2”
Right 24”
Top 12”
Bottom 10”
Front 36”
Minimum access is 36” to the front for periodic removal of the
steam tank for service and 24” to the right side for access to
the electrical components.
Four lag bolts (2) 5/16” and (2) ¼” are supplied for securing
the unit to the wall. Install the top two lag bolts (5/16”)
according to the dimensions shown below. Hang the unit
on the wall, and then install the bottom two lag bolts (1/4”).
Finally, secure all four lag bolts. Be sure the unit is level and
mounted directly to a wall constructed of wood studs at least
2” thick (or equivalent).
WARNING
Do not place unit in a location where service personnel can
not safely service this equipment or personal injury could
occur.

PLUMBING
2. Connect the water supply to the bottom of the unit using
1/4” push-to-lock tting. Supply water line should be
sized so that line pressure loss is minimal.
3. A drain line should be extended from the drain
connection to a sanitary waste. A minimum 1” ID copper
tube is recommended. If PVC is used, local codes
may require lower drain water temperature; enable the
drain tempering feature (see the control section of this
manual).
4. The skim/overow connection on the front of the tank only
needs to be connected if the humidier is being supplied
raw water containing signicant mineral concentrations.
Deionized or reverse osmosis (technical waters) may be
used and do not require the use of this feature. The
skimming cycle allows oating debris to leave the tank
through the overow drain and will reduce maintenance
intervals.
5. If using the skimmer connection, a trap must be installed
in the line so that steam can not escape from the
skimming connection during operation.
STEAM DISTRIBUTION
Herrmersion units may be used with stainless steel duct
dispersion tubes for injecting steam directly into the ductwork.
A minimum of 3 feet downstream clearance is required
for many applications; however differing psychrometric
conditions may require a greater distance. If required, consult
the factory to design a guaranteed absorption Herricane –
CS Steam Distribution System.
To make the necessary connections for water ll, drain, and
overow/skim; the following steps are required. Refer to the
illustration below for dimensional information regarding the
ll & drain connections.

Mount the unit as close to the dispersion tube as possible.
Use 1.5” Type L insulated copper whenever the length of run
exceeds 20 feet. Do not exceed a 30 foot run as the capacity
of the humidier may be decreased by as much as 15% and
the increased static pressure could cause problems with the
ll system. The maximum duct static pressure is 5” W.C.
Any insulation inside the bulk evaporation zone (inside the
ductwork) should be removed.
Steam holes in factory supplied duct dispersion tubes are
located 2” from the mounting plate and are designed for a
maximum 1” thick duct wall. Consult the factory if special
hole locations are required.
Do not install or mount standard dispersion tubes in a vertical
position or in a vertical airow application. Special dispersion
tubes are available from the factory for installations which
require vertically mounted tubes or horizontal tubes with
vertical airow.
1. Install an external shut-off valve between the water
supply and the humidier for ease in servicing the unit.
