Installation Guidelines for Elite Environmental Control Unit

Each Elite Environmental Control Unit comprises a display panel, display cable, and a control circuit board assembled into the air conditioning unit's electrical box. Determine the proper location of all components before proceeding with the installation.

Locate and secure the air conditioning unit in a dry, accessible area with the fastener provided. Secure remote electrical boxes containing the Passport I/O circuit board with the fittings provided. The central system condensing unit;s electrical box can remain factory-installed on top of the unit. Some electrical boxes contain position-sensitive components and require correct mount positioning.

Allow adequate access for all wiring connections. Wiring and circuit breakers must be sized according to marine design standards. Only stranded tinned copper wire must be used. Make sure all components are properly grounded.

Determine proper location for the display panel in he cabin area (see installation manual) and cut out the the bulkhead for mounting (3.31" W x 2.19" H). Properly route and secure the display cable between the control board and the display panel.

Note: In central system applications, the display cable could be routed with the refrigerant line set from the condensing unit to the evaporator/blower assembly. Leave a few inches of extra cable at each end for ease of installing or removing components. Do not stretch or pull a cable. Do not use staples to secure any cable. Plug in the display cable(8-pin connector). Attach the other end of the display cable to the display panel. Secure the panel to the bulkhead. The optional remote air sensor, when used be plugged into the 6-pin socket on the circuit board marke "J4" (ALT AIR). It must be located and installed properly in the return air stream. When used as an outisde air temperature sensor, it must be plugged into socket "J3" (OAT), routed and secured properly to a pre-determined location outside the cabin areas. The sensor should not be located in direct sunlight. Refer to the AH-Elite operations manual for proper programming and locations of air and chiiled water sensors.

The new optional "Pump Sentry" feature monitors condenser coil temperature, and shuts the system down if the the coil gets too hot due to loss of seawater flow. The 6-pin water sensor must be plugged into socket "J5" (SERVICE/H2O). Connect the water sensor to the condenso coil water outlet and insulate it. When using the AH-ELite with a chilled water air handler, plug the water inlet cable into socket "J5" (SERVICE/H2O).

Access to the control circuit board is achieved by removing the screws on the electrical box. Slide the front piece containing the components away from the mounting base. Turning this piece over to any side will expose the circuit board and electrical components. A complete wiring diagram is secured to the inside of the mounting base and /or in the operations manual for reference. Be sure that power is "off" before opening electrical box.
