Introduction any such substances shall not be subject to the prohibition set forth in the proceeding sentence.” * Class I substances include CFC-12 ** Class II substances include HCFC-22 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 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.
Minimum Tools Required water from standing in the pan. See item 7 for instructions on connecting two drain lines. • Screws drivers 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.
The speed scoop intake must face forward and not be shared with any other pump. A seawater strainer is mandatory between the shut off valve (seacock) and the pump to protect the pump from any foreign matter. Failure to install a seawater strainer will void the pump warranty. The seawater system should be installed with an upward incline from the speed scoop & seacock, through the strainer, to the inlet of the pump and then up to the inlet of the a/c unit’s condenser coil.
vessels bonding system also. This will help eliminate any possibility of corrosion due to stray current or voltage. The correct size circuit breaker should be used to protect the system as specified on the a/c unit’s data plate label. A minimum of 12 AWG boat cable should be used to supply power to the a/c unit and the seawater pump. All connections shall be made with ring or captive fork terminals. Turn off a/c power supply circuit breaker before opening electric box. See Figures 9 and 10.
❑ Seawater pump is at least one foot below water line and securely mounted Grilles and Ducting ❑ Strainer mounted below pump with access to filter ❑ Return air grille mounted as low and as close to the a/c unit as possible ❑ Supply air grille mounted as high as possible ❑ Double/reversed stainless steel hose clamps on all hose connections ❑ Return air grille mounted away from bilge vapors or exhaust fumes ❑ Threaded seal tape on all threaded connections ❑ Ducting is pulled taut, straight, smooth and
Operation Mechanical Control Panel (MCP) Operation Note: Do not turn the unit off and immediately turn it back on. Wait at least 30 seconds. Quick Start Operations Checklist Note: Do not turn the unit off and immediately turn it back on. Allow at least 30 seconds for refrigerant pressure equalization.
Troubleshooting General Troubleshooting Fault: Low airflow. Fault: Will not start. Possible Reason/Correction Possible Reason/Correction 1. Airflow is blocked. 1. A/C circuit breaker is off. 2. Fan Coil is iced. 2. Control is not turned on. Fault: Fan coil is iced. 3. Wrong wiring at terminal strip. Possible Reason/Correction 4. Push-on butt connectors became disconnected during installation. 1. Thermostat set point is too low. 2. Improper airflow. 5. Input line voltage is insufficient. 3.
Fault: Fan is not running but the compressor is. Fault: “LPF” is displayed. Possible Reason/Correction 1. Low-pressure switch is open due to low seawater and/or low return air temperatures. Possible Reason/Correction 1. Failed triac on Passport I/O circuit board. 2. Low pressure switch is open due to loss of refrigerant. Fault: Fan runs continuously although it is set to cycle with compressor. Fault: “ASF” is displayed. Possible Reason/Correction Possible Reason/Correction 1.
