with water analysis and application data prior to selecting
equipment.
NOTE: If units are mounted in outdoor enclosures, conditions
inside enclosure must be maintained as shown above.
Mounting
The Herrmidicool system consists of two basic components:
the control cabinet and the atomizing head manifold
assembly.
The control cabinet should be mounted so that the water
outlet of the control cabinet is level with or below the water
manifold in the air handler. Air vents must be mounted on
any loops necessary to connect the cabinet to the manifolds.
Minimum Cabinet Clearances:
Top: 1’ Bottom: 2’
Sides: 2’ Front: 4’
Hang the cabinet on the wall or unistrut mounting frame.
Two keyhole slots and two additional mounting holes are
provided. Be sure the unit is level and mounted directly to
the wall to wood studs as least 2” thick (or equivalent).
The atomizing head manifolds consisting of air manifolds,
atomizing heads, water manifold and unistrut brackets are to
be located as shown on specific layout drawings with each
job. Typically, a “unistrut” style mounting structure is field
fabricated to support the atomizing manifold.
Manifold Installation:
1. Install the air/water manifolds per the layout drawing for
project.
2. Use only copper, plastic or stainless steel piping as
specified in your print package.
3. Keep runs between control cabinets and heads as short
as possible.
4. Piping runs between control cabinets and manifolds
should be as direct as possible. If loops are unavoidable,
automatic air vents must be supplied and installed.
WARNING
Do not mount any controls inside the unit or tap power
from any location in the unit, except as stated in these
instructions. Do not place objects near the cabinet.
Do not attach to dry wall without studs.
Plumbing
Each cabinet has an air inlet, water inlet, air outlet, water
outlet and a drain outlet. All air connections are ¾” and all
water connections, including drain, are ½”.
NOTES:
1. Drain loop must extend 3” above highest location of
heads or water outlet port on cabinet. This loop allows
water pressure to be relieved on system shutdown. If
blowdown system is used, drain loop is not required.
2. Piping from control cabinet to manifolds should be ¾” for
the air and ½” for the water piping unless otherwise shown
on your job specific drawings provided for your project.
CAUTION
Any minerals that are in the water will be injected into
the airstream. Your application/process may require
some means of air or water filtration to complete a
successful application. Consult the factory if you
should have any questions. Softening the water
only increase the TDS level.
NOTE:
Inlet water pressure must be in range of 50-100 psig. Consult
the factory if you are outside this range.
