CEILING MOUNTED AIR HANDLER
CHP
DESCRIPTION
The EMI CHP is a highly effective ceiling mounted evaporator
for applications where fully exposed or partially recessed cabinetry
can be used. For partially recessed mounting, these units easily
adapt to standard T-bar, drop-ceiling openings. The CCP/CHP is
designed for residential and commercial applications where the
unit may be concealed in soffits or other structural spaces with
only the intake and discharge grilles exposed. When concealing
the unit make provisions to the soffit for future access to the unit
for maintenance purposes. When offering the Infra-Red Control
option, due to the fact that the infra-red receiver is located on
the unit, the CHP model cannot be mounted in a soffit or another
structural space.
The aluminum supply air louvers are dual adjustable for air
flow direction, to provide air flow throws to suit any installation.
The louvers are mounted in a high impact polystyrene front sec-
tion. The CHP incorporates dual blowers that produce efficient,
quiet operation, suitable for both residential and commercial
applications. A wide range of options are available for the CHP
units, including supplemental electric or hydronic heat options,
a factory or field installed condensate pump, and optional digital
and hand held IR remote controls.
The CHP models are fast and easy to install with 24V control
circuits to the outside unit, standard. Hanger brackets and fresh
air openings are standard on all models. Optional trim kits are
available for surface mounting applications.
NOTE:
If equipped with hydronic heat, the CHP will
only operate as a single-stage heating unit and not as
a two-stage heating unit.
ITEM FOR CONSIDERATION
Ensure that the CHP interconnect tubing is within a maximum
allowable length of 100’ including, a maximum 35’ lift.
MOUNTING PREPARATION
Choose the best location for the unit. Use the cardboard template
(provided with unit packing) to “test fit” the unit before installation
1. The CHP Series is designed to be mounted to a horizontal
surface which should be plumb and level.
2. Using the template, mark a spot where the piping should
penetrate the wall.
3. Determine appropriate hole size and cut through the
mounting surface.
Piping for new construction can be roughed in before wallboard or
panels are put in place. PVC pipe may be used as a pipe chase.
MOUNTING
1. Remove access panel, attach the front panel and louvers
to the chassis section with supplied nuts.
NOTE:
Front panel shipped separately in cartoning.
2. Secure the unit to the ceiling using appropriate hardware
(screws for wood, anchors for masonry).
3. The CHP unit can be ceiling suspended using threaded rods
and double nuts to ensure fasteners won’t loosen.
4. Pitch the unit slightly towards the drain for proper conden-
sate removal.
5. Run power wiring and refrigerant lines into the unit.
REFRIGERANT PIPING
CHP units are equipped with a piston flow regulator expansion
device. Piping connections are standard flare type
(flare nuts
not included)
.
NOTE:
See specifications for line sizing and actual unit
connections.
1. Be certain there are no burrs on either side of the tubing.
2. The large line (suction) should be insulated with closed cell
foam tube insulation. Do not insulate the small liquid line.
PIPING DO’S AND DON’TS
• Avoid piping on a rainy day.
• Use refrigerant grade copper tubing.
• Use a tubing bender and avoid unnecessary bending.
• Cap ends of lines until ready for final connections.
• Install a P-trap for every 10’ of vertical rise.
NOTE:
Connections to outdoor sections should be made
according to the outdoor section installation instructions.
OPTIONAL CONTROLS & COMPONENTS
See page 4 in Common Section for
complet list of Optional Controls/Components
FRESH AIR
This is a 4” round knockout and will accept a 4” round duct.
Dampers, wall collars, and outdoor grilles are field supplied. Do
not allow moisture or other foreign matter to enter through the fresh
air intake. When ducting, pitch slightly to the outside to prevent
moisture from entering the chassis.
