Air Conditioner - Regal 53 SC Owner's Manual

AIR CONDITIONER:

Before each outing inspect the thru-hull fitting for
leaks. Make sure the seacock is open. Also, the sea water
strainers located under the engine room center walk-thru
should be checked periodically for foreign objects and
accumulated debris. To clean the strainer, fi rst position the
seacock handle to the "off " position. Unscrew the strainer
fasteners by turning counterclockwise, remove the wire
strainer, and blow it out if possible with compressed air.
Reinstall the strainer, make sure the gasket on the top of
the seacock is centered, and tighten the fasteners. Check
for leaks since sucking air into the system could cause the
seawater pump to malfunction. See the illustration.
Inspect the air fi lter monthly. The air conditioner fi lter is
located at the condensation unit at both forward and aft A/
C units. To clean the fi lter remove it and rinse with plenty
of fresh water. Blow with compressed air as needed.
Check the AC hose output located on the hull side insuring
there is a full discharge when the AC pump is running.
If there is little or no discharge shut down the unit and
immediately fi nd the cause of the problem.
Periodically check the drain located at the compressor to
make sure the entrance to the hose at the AC pan is not
clogged with foreign matter.
If clogging occurs, blow out the hose with compressed
air and pour in a bleach/water solution at 5/1 parts water
to bleach.
Be sure to read and understand the A/C owner's manual
before attempting any maintenance. It covers the operating
system and equipment more thoroughly than can be done
here. Pay close attention to all safety labels since both high
pressure and high voltage are part of the A/C system.

TO PREVENT BODILY INJURY OR DEATH!
DISCONNECT THE A/C BREAKER AT THE
MAIN A/C PANEL BEFORE OPENING ANY
COVER ON THE A/C UNIT.
REVERSING VALVES
All reverse cycle units use a reversing valve: the valve must
be energized periodically to keep the internal parts moving
freely. To do this, switch the AC unit into heat for a few
seconds once a month.
SEAWATER STRAINER
Check the AC pump for proper seawater fl ow by cleaning
the seacock strainer basket. Check the overboard discharge
for proper water fl ow. Check seawater intake speed scoop
for obstructions. Make sure hoses are not looped, kinked
or crushed.
