L-2028 Installation
housing an engine or generator, nor in a bilge, unless the
drain is connected properly to a sealed condensate or shower
sump pump. Failure to comply may allow bilge or engine room
vapors to mix with the air conditioners return air and contami-
nate living areas which may result in injury or death.
Consideration should be given to installing a trap in the
condensate drain line(s) so that normal discharge of conden-
sate can fill the trap and prevent the ingress of carbon
monoxide (CO) or other potentially harmful vapors.
Installation and servicing of this system can be hazardous
due to system pressure and electrical components. When
working on this equipment, always observe precautions
described in the literature, tags and labels attached to the unit.
Follow all safety codes. Wear safety glasses and work gloves
and place a fire extinguisher close to the work area. The
following is a summary of the labels on the unit:
! DANGER Electrical shock hazard. Disconnect voltage at
main panel or power source before opening any cover. Failure
to comply may result in injury or death.
! WARNING
This component does not meet Federal require-
ments for ignition protection. Do not install in spaces contain-
ing gasoline engines, tanks, LPG/CPG cylinders, regulators,
valves or fuel line fittings. Failure to comply may result in injury
or death.
NOTICE This component is charged with hydrochlorofluoro-
carbon (HCFC) refrigerant R22. Effective July 1, 1992 it shall
be unlawful for any person to knowingly vent or otherwise
knowingly release any class 1 (CFC) or class 2 (HCFC)
substance as a refrigerant in a manner which permits such
substance to enter the atmosphere per the clean air act of
1990. Public law 101-549 Title IV Section 608-c. Failure to
comply may result in severe penalties, including fines and
imprisonment. Note: The Cuddy dc unit is charged with
R417A.
! WARNING
To minimize the hazard of electrical shock and
personal injury, this component must be effectively grounded.
Refer to the installation guidelines for further information.
! WARNING The compressor and fan on the Cuddy dc air
conditioning unit are AC voltage components, running on
115VAC supplied by the DPM. The pump and 2-knob
mechanical control also run on 115VAC supplied by the DPM.
Disconnect voltage at main panel or power source before
opening any cover. Failure to comply may result in injury or
death.
Placement Of System
Selecting a good location for your air conditioner is the most
important part of your preparations. Be sure to consider the
size of the area you are cooling, the air distribution needs,
and the size of the unit you have chosen. Keeping in mind that
cool air has a tendency to fall, it is highly recommended that
you locate the supply air grill as high as possible in the cabin.
Figure 1a at the back of this manual shows the single duct
application and Figure 1b shows a dual duct application.
The air conditioning unit should be installed as low as
possible,
but never in the bilge or engine room areas.
Insure that the selected location is sealed from direct
access to bilge and/or engine room vapors
. Installing the
unit as low as possible (such as under a V-berth, dinette seat
or bottom of a locker) and ducting the supply air as high as
possible, creates an ideal air flow condition. This type of
installation will prevent short or premature cycling.
The unit should be positioned on a firm, level, horizontal
surface and the condensate drain line should run downward
from the unit to a suitable drain location. Plan all connections
which must be made including ducting, condensate drain,
seawater in and out, electrical power connections, location of
control, and seawater pump placement, to assure easy
access for routing and servicing.
Tools Required for Installation
• Screw drivers
• Pliers
• Pipe wrench
• Wire cutters/crimpers
• Drill & 7/8" bit
• Jig saw
• Duct tape
• Electrical tape
• Teflon tape
• Bedding compound to seal thru hull fittings
• Hardware to secure unit, pump, strainer, grills & control
panel
Spacing Allowances & Unit Dimensions
The following space allowances should be considered when
mounting the unit:
1. Allow a minimum of 6" (152mm) around the perimeter of
the unit in the area of the seawater and condensate drain
piping.
2. Allow a minimum of 3" (76mm) of air space in front of the
evaporator coil for the return air intake if it is adjacent to a
bulkhead.
3. Allow a minimum of 3" (76mm) of air space for the electric
blower motor ventilation. For Cuddy dc systems, allow at
least 1" (25mm) above DPM for adequate ventilation.
4. For flexible ducting connection, allow 2" (51mm) for the
duct ring, 1" (25mm) for the duct bend radius and add
diameter of the ducting to get the total clearance distance
(2" [51mm] + 1" [25mm] + duct diameter) as measured
from the blower outlet (this also applies to clearance
needed behind the supply air grill). Note that the blower
and duct ring can be positioned either vertically or
horizontally. See Figure 2 at the back of this manual.
