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
housing an engine or generator, nor in a bilge, unless the
drain is connected properly to a sealed condensate or shower
sump pump.
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.
! 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.
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 Zephyr 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" around the perimeter of the unit in
the area of the seawater and condensate drain piping.
2. Allow a minimum of 3" of air space in front of the evapora-
tor coil for the return air intake if it is adjacent to a bulk-
head.
3. Allow a minimum of 3" of air space for the electric blower
motor ventilation.
4. For flexible ducting connection, allow 2" for the duct ring,
1" for the duct bend radius and add diameter of the
ducting to get the total distance as measured from the
blower outlet (this also applies to clearance needed
