42C System Operations - 2
The desired zone temperature is manu-
ally set on the “Passport Control” and the
air conditioning unit is activated to supply
cooling or heating as required to constant-
ly maintain the temperature selected. The
photo below shows the control.
Each air conditioning unit will operate in
a “Dehumidifi cation” mode upon demand
and is controlled by the “Passport Con-
trol”. Refer to the Marine Air Systems
Operation and Maintenance Manual for a
complete description and instruction in the
operation of this mode.
Operation of the Air Conditioning/Heating
System in your 42C is as follows:
Turn ON the respective air conditioner
breaker switch, located on the AC/DC
Electrical Panel (See AC/DC Electrical
Pages in the System Operations Section
of this manual).
Make sure seawater intake is open and
seawater pump is operating properly.
Refer to the Marine Air Systems Opera-
tion and Maintenance Manual for a de-
tailed description of the function of each
button located on the “Passport Control”.
Both Air Conditioning units create con-
densation, which creates water that has
to be drained. The forward unit drains
into the shower sump pump. Make sure
shower sump circuit breaker is turned ON
when operating the Air Conditioning. The
aft unit has its own drain which discharges
directly overboard.
Turn ON the power button located on
the respective air conditioning unit “Pass-
port Control”.
Press the fan speed button on the
“Passport Control” until the desired speed
is obtained.
Press the appropriate temperature con-
trol button (Down/Up) to obtain the desired
temperature.
Only certifi
ed and trained service techni-
cians should perform maintenance of your
Air Conditioning/Heating System. Contact
your Silverton Dealer for general mainte-
nance and winterization of the system on
your 42C. Untrained persons may care-
fully perform routine maintenance, such
as the cleaning of fi lters and the exterior
surfaces of the condensing coils.
