Fresh Water Tank; Water Pump - Nucamp Cirrus 620 2021 Owner's Manual

CAUTION
Never exceed 50 PSI when using the city
water connection with the fresh water
system. Water damage may occur if fittings
or pipes fail under excessive pressures.
CAUTION
Never run the water pump dry. Damage
may occur and your pump may be
ruined. Follow all supplied manufacturer
instructions to properly operate pump.
HOT WATER?
The number one issue the nuCamp
Customer Service Team is asked concerns
the issue of no hot water. This is a simple
fix and is only a matter of adjusting the
hot water mixing valve to the (+) symbol
located near the Alde® boiler. Follow
manufacturer instructions for proper
valve adjustment.

FRESH WATER TANK

An equipped fresh water holding tank stores water for you to use when dry
camping. Important information:
• The fresh water tank has an overflow drain connected into it that
also serves as an air outlet when the tank is being filled. It is not
unusual for water to drain out of this drain when the tank is filled.
• Do not overfill the fresh water tank. If water is draining from the
tank's overflow drain, immediately open the fresh water tank
drain valve and release water until there is no more water coming
from the overflow.
• The tank's water holding capacity may be higher than the amount
of water that can be pumped out of the tank and used. This is
normal due to the slight expansions of the tank when water is
inside it and the limitations of where the low point drain exits the
fresh water tank. A few gallons may be trapped inside at any
time. This can sometimes be remedied by dropping the side, front
or rear of the camper so as much water as possible flows into the
low point drain.

WATER PUMP

There are two 3-way switches for the water pump. One is located on the
nuCamp monitor panel and the other on the Nautilus Plumbing Control
panel. Either one can be used to control the pump. When the pump is
turned on it will run until the line is pressurized to about 45 PSI. The water
pump can be accessed under the dinette close to the shower wall. Refer to
the Water Pump Owner's manual for detailed operating instructions.
Initial Start-up process and normal operation:
1. Make sure the fresh water tank is filled.
2. Place the pump control switch in the ON position.
3. Open all water outlets, both hot and cold, one by one.
4. Allow time for the system to be filled. Shut off each faucet as the
flow becomes steady and free of air. When the last faucet is turned
off, the pump should turn off as well.
5. The system is now pressurized and ready for normal operation and use.
6. During normal operation the pump will cycle on whenever a water
outlet source is turned on or when pressure drops in the line. A
check valve in the pump will keep water from back flowing.
7. If the pump cycles frequently while there are no water outlets open,
you may have one of three common issues:
a. Debris accumulation in the filter. Remove and clean.
b. Leak in the line between tank and pump. Have your dealer
repair the system.
c. Pump needs priming. This is sometimes due to a weak pump,
which will need to be replaced by your dealer.
