INTRODUCTION Congratulations on the purchase of your Marine Air Systems’ Vector Compact® air conditioner. No matter which of the following features was the reason for your purchase of this air conditioner, we are sure it will meet your needs and will give you many years of efficient and trouble free use.
INSTALLATION Unpacking and Inspection Notice 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.
Minimum Tools Required utilized. This will help to prevent water from standing in the pan. See item 7 for instructions on connecting two drain lines. • Screws drivers • Pliers IMPORTANT! 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.
line and as close to the keel as possible in any application, but especially on a sailboat, to keep the intake in the water when the boat heels over so that air does not get into the system. (See Figure 7 for proper installation.) duct diameters and their corresponding supply and return air grille minimum area in square inches. If a transition box is used, the total area of supply air ducts going out of the box should at least equal the area of the supply duct feeding the box.
Electrical Connections, Grounding and Bonding ABYC standards are available from: American Boat and Yacht Council 3069 Solomons Island Rd. Edgewater, MD 21036 Telephone: (410) 956-1050 All a/c units have a terminal strip mounted inside the electric box. The terminal strip is labeled for proper connections of the electrical supply, ground wires and pump circuits. A wiring diagram is provided in the electrical box and in this manual.
Installation Checklist Electrical (Review prior to installation) ❑ The wiring diagram is located in the electrical box. If that diagram is damaged or if you need a copy, please call Dometic with the unit part number, serial number, and wiring diagram number, all of which are located on the unit data plate. Note: Refer to the Elite and Passport I/O manuals for installation and operation of those digital controls.
OPERATION Mechanical Control Panel (MCP) Operation Quick Start Operations Checklist 1. Ensure seawater intake ball valve (sea cock) is open. ❑ Turn on the a/c circuit breaker. If the seawater pump has its own circuit breaker, turn that on. ❑ Ensure seawater intake ball valve (sea cock) is open. 2. Turn SYSTEM SWITCH control knob to OFF. ❑ Turn the system on. 3. Turn on AC circuit breaker. If the seawater pump has its own circuit breaker, turn that on too.
TROUBLESHOOTING General Troubleshooting 5. Seawater temperature too high for cooling or too low for heating. Also see specific digital or mechanical control troubleshooting sections following these general guidelines. Seawater temperature will directly affect a/c unit's efficiency. This a/c unit can effectively cool your boat in water temperature up to 90°F and heat (if reverse cycle option is installed) in water as low as 40°F. Fault: Will not start. 6.
3. Seawater temperature too high for cooling or to low for heating. Fault: Low airflow. Possible Reason/Correction Seawater temperature will directly affect the a/c unit's efficiency. This a/c unit can effectively cool your boat in water temperatures up to 90°F and heat (if reverse cycle option is installed) in water as low as 40°F. 1. Airflow is blocked. Remove any obstructions in return air stream. Clean return air filter and grille.
Fault: Fan runs continuously although it is set to cycle with compressor. Fault: System runs continuously. Possible Reason/Correction 1. Improper air sensor location. Possible Reason/Correction Verify display head location with criteria found in the control manual. Install alternate air sensor if necessary. 1. Failed triac on Passport I/O circuit board. Send for repair or call local service technician (see back of book for a listing). Fault: No cooling or heating. Fault: “HPF” is displayed.
2. Damaged jack/socket in display head or on circuit board. Visually check to see that pins inside socket are not bent or corroded. Repair or replace display or circuit board if needed. Fault: “PLF” is displayed (Elite Digital Control only). Possible Reason/Correction 1. Indicates that seawater flow through the condenser coil is insufficient. Check for adequate seawater flow. Verify pump operation. Inspect the condenser coil, it may need cleaning (see maintenance section).
MAINTENANCE Reversing Valves Return Air Filters Reverse cycle units have a reversing valve; the valve must be energized periodically to keep the internal parts moving freely. To do this, switch the a/c unit into heat for a few seconds once a month. Check the return air filter about once a month and clean as necessary. To clean the filter, remove it from the unit, rinse with water, air dry and reinstall.
