Important Installation Notes for Air Conditioners
Mounting Styles: 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 (Side/Front/Back) Mounting:
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.
Wiring:
There are two locations for wiring. One for the main AC input, the other for
the DC control signals. To access these locations remove the top hot side
shroud. There are 4 small enclosures underneath, two of which have 3/4
NPT taps provided for locally and nationally approved conduit fittings. Remove the
cover from each of these small enclosure to perform the final wiring connections.
Refer to wiring diagram SK011101 provided in this documentation.
Condensate Removal System:
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.
Top Mounting:
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.
Maintenance:
Since the technology is solid-state, there are no filters, compressors, or fluorocarbons to maintain. The only moving parts are the fans.
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.
Cautions:
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.
Notes on condensation:
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.
