L-2200 Installation
Blower Assembly
Horizontal or vertical supply air discharge may be
achieved by rotating the blower. Its design allows the
blower to be rotated by removing the screws holding the
blower plate to the evaporator coil shroud. Rotate the
blower to allow the most direct flow of air to the supply
air grille.
To rotate the 10-16K blowers, remove the two
plastic plugs for access to the mounting screws.
Supply & Return Air Grilles
and Transition Boxes
As previously indicated, install the supply air grille(s) as
high as possible and the return air grille as low and
close to the air conditioning unit as possible to insure
direct uninterrupted airflow to the evaporator. In no
instance should the supply are grille discharge be
directed towards the return air grille, as this will cause
the system to short cycle.
The cut out for the 3" (76mm) round supply air grille for
the 3.5K unit is 3" (76mm) in diameter and the flange is
3

" (99mm) in diameter. The cut out for the 4" (102mm)
round supply air grille for the 5K unit is 4" (102mm) in
diameter and the flange is 5½" (140mm) in diameter. The
cut out for the rectangular supply air transition box used
with the 10 & 12K units is 11
5 /
8
" (295mm) by
5 5 /
8
" (148 mm) and for the 16K unit it is 13 5 /
8
" (346mm)
by 5 5 /
8
" (148 mm). Connect the 6" (152mm) or 7"
(178mm) oblong duct ring to the transition box by first
placing the ring on the box and tracing the hole. Cut the
oblong hole out of the box. Secure the ring to the box
with rivets (trim ¼" [6mm] from ring flanges if necessary).
Completely seal the joint between ring and box with
silicone. A minimum clearance of 3" (76mm) plus the
duct diameter size is required behind the grille for
attaching the ducting (see earlier section, “
Spacing
Allowance and Unit Dimensions”).
The cut outs for the return air grilles are as follows:
7-5/8" (194mm) square for the 3.5K & 5K units,
11-5/8" (295mm) square for the 10K & 12K units, and
13-5/8"(346mm) x 11-5/8" (295mm) (width x height) for
the 16K unit. The return air grille should have a minimum
of 4" (107mm) of clearance in front of it, free from any
furniture or other obstructions. The return air filter,
mounted to the front of the evaporator, removes debris
from the air prior to the air being drawn across the
evaporator coil and fins. Dust and lint can clog and
reduce airflow across the evaporator coil resulting in
poor performance. See the “
Maintenance” section for
filter cleaning instructions.
Ducting
Good airflow is critical for the performance of the entire
system. It is highly dependent on the quality of the
ducting installation. The ducting should be run as
straight, smooth and taut as possible minimizing the
number of 90 degree bends (two tight 90 degree bends
can reduce airflow by 25 percent). The following is a
summary of proper ducting connections:
1. Pull back the fiberglass insulation exposing the inner
mylar duct hose.
2. Slide the mylar duct hose around the mount ring until
it bottoms out.
3. Screw 3 or 4 stainless steel sheet metal screws
through the duct hose into the transition ring. Make
sure to catch the wire in the duct hose with the heads
of the screws. Do not use band clamps, as the hose
will slide off.
4. Wrap duct tape around the ducting and ring joint to
prevent any air leaks.
5. Pull the insulation back up over the mylar to the ring
and tape this joint.
6. Remove excess ducting and use the same connection
method at the supply air grille.
Manual Control Panel Installation
The manual control panel should be located within cap
tube length of the air conditioning unit. The dimensions
for the 2-knob panel are 3¼" (83mm) x 5½" (140mm).
The cut out size for the 2-knob panel is 2½" (64mm)
wide by 4¾" (121mm) tall. (Refer to Figure 5 at the back
of this manual.) Once the cut out is made, carefully
uncoil the copper cap tube with return air sensor (copper
bulb) and route the control wires and cap tube through
the hole and back to the unit
using caution not to kink
the cap tube. Mount the return air sensor into the clips
provided on the evaporator coil. If the return air sensor
cannot be mounted on the evaporator coil, mount it
behind the return air grille. The sensor must be mounted
in the return air stream. Make electrical connections
according to the wiring diagrams provided. (See wiring
diagrams, Figures 7-10 at the back of this manual.)
Electrical Connections, Grounding
& Bonding for AC Powered Cool
Mate
All Cool Mate units have a five position terminal strip
mounted inside the electric box. The terminal strip is
labeled for proper connections of the electrical supply,
ground wires and pump circuits. Wiring diagrams are
provided in the electrical box and in this manual. The
correct size circuit breaker should be used to protect the
system as specified on the air conditioning unit’s data
