English L-2254 Installation
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 3-knob
control (if mechanical option is used), 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
VERY IMPORTANT: 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 hazard-
ous 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 containing gasoline engines, tanks, LPG/
CPG cylinders, regulators, valves or fuel line
fittings. Failure to comply may result in injury or
death.
INSTALLATION
Notice
This component is charged with hydrochloro-fluorocarbon
(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.
Caution
High compressor temperature is normal.
Do not touch.
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 grille as high as possible in the cabin. See Figures 2
and 3.
The Vector Compact unit should be installed as low as
possible, BUT NEVER IN THE BILGE OR ENGINE
ROOM AREAS. INSURE THAT THE SELECTED LOCA-
TION 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 airflow 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.
