Dometic turbo a/c systems
The following is a summary of the seawater system
installation:
1. Install the seawater scoop thru-hull inlet as close to
the keel and as far below the water line as possible,
facing forward. Bed the scoop with a marine sealant
designed for underwater use.
2. Install a bronze, full flow seacock on the
scoop thru-hull inlet.
3. Install a seawater strainer below the level of the
pump with access to filter.
4. Mount the pump above the strainer and at least
one foot below the waterline.
5. Connect the seacock and strainer with an uphill run
of reinforced marine grade hose.
6. Connect the discharge from the pump uphill to
the bottom inlet of the a/c unit's condenser coil with
enGlisH
5/8" (15.9mm) reinforced marine grade hose. Connect
the discharge from the condenser coil to the over-
board discharge thru-hull fitting with 5/8" (15.9mm)
reinforced marine grade hose.
7. Avoid loops, high spots or the use of 90° elbows
with seawater hose (each 90° elbow is equivalent to
2.5' (0.762M) of hose and a 90° elbow on the pump
seawater
outlet is equivalent to 20' (61M) of hose.
8. Double clamp all hose connections with two stain-
less steel clamps, reversing the clamps.
9. Use Teflon tape on all threaded connections.
10. Connect all metallic parts in contact with seawater
to the vessel's bonding system including the speed
scoop inlet, strainer, pump and the air conditioner.
Failure to do so will void warranty.
