NOTE: Do not drill, cut, or compromise the powder coat
finish in the wet section or behind the HMX’s or drive
screws into filter areas or where internal wiring, soap
bottles, etc has been installed. See Figure 19
Wet Area, Figure 19

If units are located inside or multiple units are
mounted side by side requiring a common working
air duct:
o
Seal ducts to prevent condensation from
leaking from the ducts
o
Provision must be made for the duct to
drain condensation back to the unit.
Connect to an appropriate drain if ducting is
lower than unit. Duct joints should be
constructed to drain water such that it will
not catch in seams.
o
Ducts may be cut in the top or on either
side of any of the units,
see Appendices 8,
10 and 12.
Top Mounted Exhaust Example, Figure 20
NOTE: If side louvers cannot be used, it is suggested to
extend the exhaust duct so that it is approximately 12 in
(30.5 cm) above the rooftop. This will help to prevent
working air from entering the system and decreasing
performance, especially on C60 models.
CAUTION: All duct connections to the unit must be able to
drain back into the unit. Ensure duct flanges mount to the
inside of the cabinet to prevent leakage of condensate. See
Figure 20 for an example.
CAUTION: Failure to prevent sunlight from reaching the heat
exchanger will allow degradation of the heat exchanger
material and possibly allow green algae growth if there is
enough dissolved nutrients in the water supply and or air.
The Clean HMX material will not support mold or algae
growth.
CAUTION: A bird screen must be installed over the outlet
exhaust to keep birds and squirrels out.
CONSIDERATIONS : The working air is always cooler than the
outside air. This air can be used to cool the back of solar
panels or directed to condenser coils (Most applications that
will not be affected by moisture).
CAUTION: Working air being drawn into the intake air will
seriously impact the temperature performance of the unit
and add significant humidity to the inside of the building.
When installing the unit on the roof or ground, use working
air louvers with protective screening (these louvers are sold
separately). Using louvers other than those supplied by
Coolerado may void the warranty.
NOTE: At least 24 inches (600 mm) should be left between
side louvers and any object to allow free air-flow.
Additionally, this will allow access for the louver panel
(which houses a filter pad that prevents water from spitting
from louver).
NOTE: Side louvers may have some condensation and excess
water carry over from the working air (which may contain
minerals) and should be located where mineral buildup
outside the unit will not be a problem.
