Reverse Heat
Optional air conditioning systems feature a reverse heat
cycle. This can be extremely valuable to boaters in colder
climates especially for early spring and late fall cruising.
To accomplish reverse cycle heating, the R-22 refrigerant
flows in the opposite direction through a reversing
valve located on the evaporator/condenser unit. Heat is
transferred from the seawater in the coil of the condenser
to the R-22 refrigerant and then to the air as it is blown
through the evaporator to the cabin.
Obviously, the temperature of the seawater will effect the
air conditioner effi ciency.
The temperature variance for cooling effi ciency is:
Up to 90 Degrees F. ( 32.2 Degrees C. )
The temperature variance for heating effi ciency is:
Down to 40 Degrees F. ( 4.4 Degrees C. )
Typical Air Conditioning System Operation
Below is a basic quick start-up checklist for the air
conditioning system.
For more in depth information,
refer to the vendor operation manual.
Operations Quick Start-Up Checklist:
1. Check the AC seawater strainer for debris.
2. Make sure the AC seawater pump seacock located in
the engine room is opened completely (handle should be
in-line with the hose).
3. Activate the forward air conditioner breaker on the boat’s
main AC control panel located in the starboard aft salon
overhead cabinet.
4. Check the hull side for a steady stream of seawater.
Seeing water here is normal when the AC pump is running.
If stream is diminished or no water emits from the fi tting
immediately turn the AC pump off and investigate the
cause of the problem.
5. Press the Elite thermostat Power button once to activate
the air conditioning system. A blank screen displays when
system is off and indicates present cabin temperature.
6. For cooling or heating press and release the Mode button
until the desired LED is illuminated ie; automatic mode.
7. Press the Up or Down button to set the desired cabin
temperature. To view the set point, momentarily press and
release the Up or Down button.
8. Auto fan LED lights when Auto fan speed is selected.
