INSTALLATION
OVERVIEW
The Dometic CR330 removes the condensate water produced during the cooling cycle of your reverse cycle air conditioner and
discharges the condensate into the air conditioner's outlet water line. The condensate is pumped overboard any time the air
conditioner's circulation pump is working and sufficient condensate is in the condensate pan of your unit. By operating on the
Venturi effect, a separate condensate pump is not required.
A water filter/strainer, a reducer and a check valve are also provided and must be installed with the CR330. The filter prevents
debris from entering the CR330 and obstructing the water flow. The check valve allows the condensate to flow in only one
direction.
WARNING
•
The seacock or ball valve in the air conditioner's supply water line must be closed when installing
the CR330. Failure to close the seacock or ball valve may result in the flooding or sinking of the boat.
•
A check valve (supplied) MUST be installed in the condensate line as described in the instructions.
A failure of the check valve may result in the flooding or sinking of the boat. Verify proper
operation of the check valve monthly.
NOTICE
The flow rate, measured at the air conditioner, must be at least 1.0 GPM (3.8 LPM) but no more than 4.0
GPM (15.1 LPM). Flow rates less than 1.0 GPM (3.8 LPM) may result in improper removal of the
condensate. Flow rates greater than 4.0 GPM (15.1 LPM) may result in a restriction of water flow to the air
conditioner. Always refer to the air conditioner's Owner's manual or Product Data Sheet to determine the
correct water flow for proper operation of the air conditioner.
INSTALLATION
NOTICE
Before installing the CR330, turn the circuit breaker off to the air conditioner and to the water pump, if the
pump has a separate breaker. If the pump turns on while the seacock or ball valve is closed, damage to the
pump may occur.
The CR330 is installed into the outlet water line of the air conditioner. The discharge water flows through the CR330 to the
overboard thru hull fitting. Condensate from the drain pan is pulled into the CR330 and is pulled overboard by the discharge
water from the air conditioner. See Figure 1, page 4.
Included in the installation materials are 1/4" clear tubing and 5/8" clear tubing. Various lengths of this tubing must be cut to
connect the components. To optimize the safety and performance of the system, be sure to follow the recommendations for the
lengths of tubing. See Figure 1, page 4.

NSTALLING THE
Locate the outlet (discharge) water line on your air conditioner. Follow the water line, looking for a suitable place to install the
CR330.
NOTE:
•
The CR330 must be secured to a bulkhead to prevent movement while the boat is underway.
•
The CR330 does not have to be level, but the minimizing of bends in the tubing will improve the performance
of the CR330.
•
The filter/strainer must be checked and cleaned regularly. Put the filter/strainer in an easily accessible place.
•
Use pipe dope to seal all threaded connections.
CAUTION
Overuse of sealer will cause the CR330 (see Figure 1, #12, on page 4) to become clogged and inoperative,
and may result in flooding.
1.
Cut the water outlet line between the air conditioner and the thru hull fitting where the CR330 is to be installed.
