L-2028 Installation
Zephyr and Cuddy dc Units • Installation
Powered Cuddy dc”. Cuddy dc owners may skip the sections
that are subtitled “for AC Powered Zephyr.”
Cuddy dc
kits contain the air conditioning unit and these
three components: a Dedicated Power Module (DPM), a 2-
knob mechanical control, and the water pump. Each of these
components is connected to the a/c unit with a polarized plug.
These plugs are configured unique to each component. The
DPM is sized to run the Cuddy dc system only and should not
be used for any other appliance(s). See Figure 14 in the back
of this manual for DPM specifications
! WARNING
The DPM is not ignition protected and must not
be installed in the engine compartment or in any area with
flammable or compressed gasses or liquids (see the Safety
Considerations section of this manual for more information).
Dometic recommends using a separate battery bank dedi-
cated to run the
Cuddy dc
. For specific instructions, please
see the two sections in this manual titled “Electrical System
and Wiring for DC Powered Cuddy dc” and “Electrical Con-
nections, Grounding & Bonding for DC Powered Cuddy dc.”
! 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.
Once the DPM is connected to the dedicated 12VDC battery
bank, then all necessary power distribution to each of the
components is handled through the polarized plugs—truly a
“plug & play” system.
Unpacking and Inspection
When the equipment is received, all items should be carefully
checked against the packing list to ensure all cartons have
been received. Move units in the normal “up” orientation as
indicated by the arrows on each carton. Examine cartons for
shipping damage, removing the units from the cartons if
necessary. If the unit is damaged, the carrier should make the
proper notation on the delivery receipt acknowledging the
damage.
CAUTION: When unpacking and installing the control, care
must be taken not to kink or break the copper cap tube when
uncoiling the sensing bulb. The cap tube is hollow and kinking
or sharp bends will inhibit system operation.
Safety Considerations
Never install your air conditioner in the bilge or engine room
areas. Insure that the selected location is sealed from direct
access to bilge and/or engine room vapors. Do not terminate
condensate drain line within three (3) feet of any outlet of
engine or generator exhaust systems, nor in a compartment
Warning
This manual contains essential safety information concerning
the safe and proper installation and operation of Zephyr and
Cuddy dc self-contained direct expansion air conditioners. It is
very important that you read and understand the contents of
this manual thoroughly before attempting to install any
Cruisair equipment. If there are any statements in this manual
that you do not understand, contact the Dometic Environmen-
tal Applications Department (Dometic) for assistance. Phone
(804) 746-1313, Fax (804) 746-7248 (8:00am - 5:00pm
United States Eastern Time).
Notice
As of July 1, 1992, United States federal law prohibits the
intentional release of refrigerant gases into the environment,
including the R-22 refrigerant mostly used in Cruisair air
conditioning systems. Special care must be taken when
installing, charging and servicing Cruisair equipment to
prevent any loss of refrigerant.
Cruisair does not recommend the practice of using refrigerant
to purge air and moisture from the system at installation. This
formerly used practice of purging is in violation of United
States federal law.
Introduction
You have just purchased the first complete built-in marine air
conditioning system designed for self installation. We are
confident you will find the added comforts experienced in your
boat to be well worth the money spent. If, upon opening your
new system, you discover any parts are missing, contact your
dealer immediately.
Before attempting to install your new Zephyr (AC powered) or
Cuddy dc (DC powered) air conditioning system, you must
read this installation manual completely. Failure to perform
certain tasks in the proper sequence could result in an
inoperative system as well as a voided warranty.
Cuddy dc
The new
Cuddy dc
marine air conditioner is very similar to
the standard Zephyr but is unique in one way–it is designed to
be run on 12VDC battery power. Most of the installation,
operation and maintenance information in this manual applies
to both types of air conditioners, the AC voltage Zephyr and
the DC voltage Cuddy dc. Installation of either unit is nearly
identical with the exception of the power supply and how that
power is connected to the unit, control and pump. With that in
mind while reading this manual, please read the Installation,
Operation, and Maintenance sections titled “Zephyr and
Cuddy dc Units”, and especially the sections subtitled “for DC
