INSTALLATION CHECKLIST (review prior to 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 is 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 and sea cock to strainer, pump and a/c unit, then
downhill (if possible) from a/c unit to overboard discharge
□ Water flowing freely from overboard discharge while pump is running
□ Pump relay panel, if used, must have its own circuit breaker sized for the pump (20 amp max)
□ All metal fittings should be bonded
Mounting
D 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 hold down clips provided
□ Condensate drain routed aft and down hill to a sealed sump (not bilge)
□ Blower rotated toward supply air grille
Electrical
□ All butt connections on pump wire tightly crimped and heat shrunk
□ AC power source installed and grounded/bonded in accordance with ABYC standards
□ Control wires connected to terminal strip with fork or ring terminals
□ Circuit breakers sized according to specifications on the data plate label
□ Passport II display cable is connected at both ends
□ Pump Relay Panel (if used) has a dedicated circuit breaker sized for the pump but not to exceed
20 amps maximum.
Grilles and Ducting
□ Supply air grille mounted as high as possible
□ Return air grille mounted as low and as close to the a/c unit as possible
□ Return air grille mounted away from bilge vapors or exhaust fumes
□ Ducting is pulled taut, straight, smooth and properly connected with no excess
QUICK START OPERATIONS CHECKLIST
□ Ensure seawater intake ball valve (seacock) is open.
□ Turn on the A/C circuit breaker. If the seawater pump has its own circuit breaker, turn that on.
□ Turn the system on.
□ Set the desired cabin temperature (set point).
□ Check for a steady solid stream of water from the overboard discharge.
□ Verify that there is steady airflow out of the supply air grille.
□ If the unit does not appear to be operating properly, refer to troubleshooting guidelines.
Note: Do not turn the unit off and immediately turn it back on. Allow at least 30 seconds for
refrigerant pressure equalization.
