Chaparral 420 PREMIERE, Owner'S/Operator'S Manual

Page: 127 / 164

Note: The air filters for each unit should be
removed and cleaned periodically to assure
fresh, clean air circulation and to reduce stress
on the unit.
To Start System:
1. The sea water inlet seacock should be open and
strainer should be free of debris.
2. Turn ON the A/C WATER PUMP AND RELAY
circuit breaker on the main AC distribution panel.
Turn ON each A/C UNIT circuit breaker located
on the same panel. 3. Set temperature on dis-
play. Select either heating or cooling.
REFER TO THE OWNER’S MANUAL PACKET FOR
INSTRUCTIONS AND WARRANTY INFORMATION.
WATER SYSTEM
The 420 Premiere is equipped with a fresh water sys-
tem consisting of one (1) 78 gallon (295.3 liter) water
tank, a 12 volt water pump, primary and secondary
water system filters and a water distribution manifold.
The fresh water system is activated by the FRESH
WATER PUMP breaker on the salon DC distribu-
tion panel. The breaker must be ON to operate the
head, faucets, shower, ice maker, and fresh water
washdowns.
Water Tank
The 420 Premiere has one (1) 78 gallon (295.3 liter)
water tank located between the port and starboard
inboard stringers underneath the V-Berth Floor.
You will need to check the water level in the tank. To
check, turn on the master head breaker. The lights will
indicate the amount of water that is in the tank.
Filling The Water Tank
Fill the water tanks only from a source known to pro-
vide safe, pure drinking water. To fill your water tank
you should use a plastic hose. Do not use a rubber
hose; it can give the water a disagreeable flavor.
The hose should be kept for filling use only.
You should empty the hose after each use. Start at
one end and raise the hose to shoulder level and walk
to the opposite end of the hose, allowing the remain-
ing water to flow out. Store your water tank filling
hose in a clean, dry place. It is also a good practice
to cover the ends of the hose to keep the inside clean.
To Begin Initial Operation:
1. Fill the water tank only with drinkable water.
2. Switch the water pump breaker to the ON position.
3. Open all hot and cold faucets one at a time, to
release air from the water lines.
4. Once air has been eliminated from water lines,
close faucets.
5. Pump should shut off when shutting the last faucet.
Winterizing The Water System
In regions where temperatures fall below freezing,
winterization of the systems and components is nec-
essary. Failure to do so will seriously damage them.
As a result of not being able to completely drain
water systems with a water heater installed, it is rec-
ommended that potable water system antifreeze be
run through the entire system at the time of winteri-
zation. This needs to be COMPLETELY flushed
before using the following spring.
