3.
Screw 3 or 4 stainless-steel sheet-metal screws through the duct hose into the mount ring. Make sure to catch the wire
in the duct hose with the heads of the screws. Do not use band clamps, as the hose will slide off.
4.
Wrap duct tape around the ducting and ring joint to prevent any air leaks.
5.
Pull the insulation back up over the mylar to the ring and tape this joint.
6.
Run the ducting to the other end, keeping it as straight, smooth, and taut as possible. Minimize the number of 90-
degree bends and dips that can reduce airflow.
7.
Remove excess ducting before attaching the duct to the opposite end. Follow the procedure above to attach the duct
as described in steps 1 through 5.

Mount the control panel on an inside wall, slightly higher than mid-height of the cabin, in a location with freely circulating air
where it can best sense average temperature. Do not mount the control panel above or below the supply-air or return-air grille,
in the supply-air stream, in direct sunlight, near any heat-producing appliances, or in a bulkhead where temperatures radiating
from behind the panel may affect performance.

1.
The control panel must be mounted within 15 feet (4.5m) of the electrical box.
2.
Make the cut out for installation of the control. The cut out size for the digital control panel is
2.5” (64mm) wide by
1.88" (48mm) tall
. The actual dimensions of the control panel are 3.19”x 2.50”x 0.94” (81mm x 64mm x 24mm). See
Figure 6: Digital Control Assembly below.
3.
Use the supplied 8-conductor RJ-45 ribbon cable to make electrical connections according to the wiring diagram in
Figure 7: Wiring Diagram for EnviroComfort Digital Control Panel, page 13.

All units have a five-position terminal strip mounted inside the electrical box. The terminal strip is labeled for proper connection
of the electrical supply, ground wires, and pump circuits. Wiring diagrams are provided in the electrical box and in the “Wiring
Diagram” section of this manual, starting on page 13. The correct size circuit breaker must be used to protect the system as
specified on the air conditioning unit’s data plate label.
Use a minimum of 12 AWG boat cable to supply power to the air conditioning unit and to the seawater pump (see “Circuit
Breaker” on page 11). Connections should be made per ABYC electrical standards.
Make all connections to the terminal strip with ring terminals. Turn off the alternating-current (AC) power supply circuit breaker
before opening the electrical box and accessing the terminal strip.

Each air conditioning unit requires its own dedicated circuit breaker. If there is only one air conditioning unit installed, the
seawater pump does not require a circuit breaker; the wiring from the seawater pump is connected to the terminal strip on the
unit. For a wiring diagram, see Figure 7: Wiring Diagram for EnviroComfort Digital Control Panel, page 13.
Use a minimum of 12 AWG boat cable to extend the wires on the pump if necessary. Connections should be made per ABYC
electrical standards.
