Follow these procedures to operate the air conditioner on shore power:
1. Make sure the air conditioner breaker in the cabin is off.
2. Plug AC shore power cord into the receptacle on the boat, and turn
clockwise to lock. Thread the locking ring on the inlet to secure the
cord. Connecting the cord to the boat first will prevent dropping a "hot"
cord into the water.
3. Make sure dockside power is off. Then, plug in the cord. Turn the dock-
side shore breaker on.
4. Immediately check the polarity light on the main cabin panel. If the re-
versed polarity light on the main panel illuminates, do not turn on the
cabin main breaker. Turn off the dockside shore power breaker and
disconnect the power cord. Inform marina manager of the problem.
5. Make sure the sea water inlet seacock is open and strainer is free of
debris.
6. Make sure the sump pump is on when you operate the air conditioner.
Condensate from the air conditioner drains to the sump pump.
7. Make sure 120 or 220 volt AC or 12 volt DC power switch for air con-
ditioner is on.
8. Set temperature on display. Select either heating or cooling.-
9. Turn selector switch to --ON. Fan, water pump, and compressor will
start.
10. Look over side of boat and check for water flowing from dis- charge
port. If water is not flowing, stop air conditioner. Check for the follow-
ing: blocked water intake, air in line, clogged sea strainer, or closed
seacock that should be open. Correct the problem before restarting
the air conditioner.

2013 Chaparral Signature Cruiser Owner's Manual
Note: On the 270 Signature Cruisers, there is an optional 12V air
conditioner. Power supplied to the optional 12V air conditioner
comes from two additional batteries located in the engine compart-
ment. These batteries are recharged when docked and connected to
shore power with the battery charger breaker on. Batteries are also
recharged by the engine alternator when the boat is underway.
Note: The manufacturer's operation manual covers detailed infor-
mation for operating the air conditioner including temperature set-
ting, display and calibration, and fan speed and calibration. Also
provided are technical data and troubleshooting information to help
you keep the unit in safe and proper operating condition.

WATER HEATER

The water heater, which runs on 120 or 220 volt AC power, has an ON/
OFF switch at the main panel in the cabin area. A check valve in the water
heater piping prevents hot water from washing back into the cold water
source. A pressure relief valve prevents damage if pressure or tempera-
ture gets higher than safe settings. The thermo stat on the water heater
is preset and is not adjustable.
Note: Refer to the water heater instruction manual for safety pre-
cautions and for detailed operation, maintenance, and winterizing
instructions. In areas where frost is possible, the heater tank must
be drained completely or filled with potable water antifreeze to
prevent possible damage during winter storage.
Before turning on power to the water heater, be sure tank is full and wa-
ter is covering the heating element. The heater tank must be kept full of
water to avoid damage to the heating elements.
The water heater has a heat exchanger which captures heat from the
engine cooling water by circulating the hot water through the exchanger
to heat potable (fresh) water in the heater. Engine cooling water circulat-
ing through heater for more than two hours results in excessively HOT
water.
