L-2028 Installation
the shut off valve (seacock) and the pump to protect the pump
from any foreign matter.
Failure to install a seawater
strainer will void the pump warranty
. The seawater system
should be installed with an upward incline from the speed
scoop & seacock, through the strainer, to the inlet of the pump
and then up to the inlet of the air conditioning unit’s condenser
coil. The discharge from the air conditioning unit should then
run to the seawater outlet thru-hull fitting which should be
located where it can be visually checked for water flow and as
close as practicable to the waterline to reduce noise. All hose
connections shall be secured by means of double/reversed
stainless steel hose clamps. Use teflon tape on all threaded
connections. The following is a summary of the seawater
system installation:
1. Install the speed 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 speed 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
5/8" reinforced marine grade hose.
6. Connect the discharge from the pump uphill to the bottom
inlet of the air conditioning unit’s condenser coil with 5/8"
reinforced marine grade hose. Connect the discharge
from the condenser coil to the overboard discharge thru-
hull fitting with 5/8" reinforced marine grade hose.
7. Avoid loops, high spots or the use of 90° elbows with
seawater hose (each 90° elbow is equivalent in pressure
drop to 2.5' of hose and a 90° elbow on the pump outlet is
equivalent to 20' of hose).
8. Double clamp all hose connections with stainless 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
.
Refer to Figure 12, 13a , and 13b at the back of this manual
for seawater kit installation drawings.
Installation Checklist
(review prior to and after installation)
Seawater cooling system
• Speed scoop located as far below the water line and as
close to the keel as possible
• Shut off valve and speed scoop properly sealed and tight
• Seawater pump at least one foot below water line and
securely mounted
• Strainer mounted below pump with access to filter
• Double/reversed stainless steel hose clamps on all hose
connections
• Teflon tape on all threaded connections
• Hose runs uphill from speed scoop to strainer, pump and
air conditioning unit
• Water flowing freely from overboard discharge while pump
is running
Air Conditioner Unit Mounting
• Not in engine room or bilge areas, must be sealed away
from exhaust or fumes
• Proper spacing allowed around unit
• Attached to solid level platform with four hold down clips
provided
• Condensate drain routed aft and down hill to a sealed sump
(not bilge), and should have a trap
Grills and Ducting
• Supply air grill mounted as high as possible
• Return air grill mounted as low and as close to the unit as
possible
• Return air grill mounted away from exhaust and bilge vapors
• Ducting is pulled taut, straight and properly connected with
no excess
Electrical for AC Powered Zephyr

shrunk
• AC power source installed and grounded/bonded in
accordance with ABYC standards

terminals
Electrical for DC Powered Cuddy dc
• All polarized plugs connected securely with an audible
“snap”
• DC power source installed and grounded/bonded
inaccordance with ABYC standards
• Bonding ground stud on Dedicated Power Module con-
nected to vessel’s bonding system per ABYC
