Notes on condensation:
Both ‘thru mount’ and ‘flush mount’ units can be positioned in
any orientation and on any enclosure surface. It is important to consider interior
air flow patterns when determining the mounting location. Also of importance
is an unrestricted flow of ambient air thru the hot side heat exchanger. Ease
of access and inspection must be considered for those applications in
particularly severe environments which may require occasional
maintenance.
Vertical mounting refers to the vertical direction of the cold side
or interior fins and is recommended for applications with high
humidity, poor and incomplete cabinet seals or any condition which
may cause the cold side fins to be maintained at temperatures
below the dew point for long periods of time allowing for the
formation of condensation. The vertical fin direction provides a drip
path whereupon condensation can be collected via a moisture
removal system (standard on FHP-units) or a drip pan positioned
below the cold side fins. Drip pans are optional for thru mount units.
All FHP-Series and AHP-1400 air conditioners contain a built-in condensate removal system. The condensate kit consists of a
antifungal sponge with a condensate wick. PVC tubing is also provided for drainage. Drip pans are optional for thru mount units
which must be evaluated on an individual basis. Equations defining a relationship between the cold side fin and enclosure
temperatures are provided to assist in the evaluation.
Though often the easiest location to mount it is often the most difficult to protect from condensation in this orientation due to the
fin orientation, gravity and any susceptible components below. If a drip pan is employed by the end user use caution to place
the pan far enough away from the internal fan to minimize the restriction of air flow. The pan should cover the fin ends as well as
the fan area. When there is a choice, the vertical orientation is preferred by most users.
Since the technology is solid-state, there are no filters, compressors, or fluorocarbons to maintain. The only moving parts are
the fans.
It is recommended for harsh or dirty environments that the heat sinks be cleaned from time to time. This can be
accomplished by directing compressed air over the external fins or on NEMA 4 versions by hosing the unit down. This will
increase the overall life and performance of the system.
Take care when mounting not to damage the seal between the hot and cold side sinks. Do not attempt to mount a unit to a
warped surface or try to make the units mounting surface conform to an unflat surface. Do not pinch or damage any leads when
mounting. Do not over tighten any installation screw, use reasonable force. Always mount with any condensate drain down.
Do not compress the cold side between the hot side and any other surface. Do not obstruct the airflow on either side. When
mounting consider the natural air flows of the enclosure. Connect power only after the installation is complete.
Condensation occurs at the cold side fins when the surface temperature goes below the dew point. To reduce or remove
condensate, consider the following:
• Regulate the Fin Temperature above the Dewpoint.
• Keep Enclosure Closed and Sealed from Outside Humidity.
• Use Desiccant (Moisture absorbing Granules.)
• Employ Condensate Removal System/Drip Pans.
