SA 3 134a - Sea Frost Refrigeration

THERMOSTAT WIRINGThe thermostat electrical leads are low voltage for safety. Connect the red thermostatwires to the red wires exiting the condensing unit.110-VOLT CIRCUITA separate 15-amp breaker is required for the 110-volt circuit. The Shore Assist isprovided with a 3 wire male plug. A standard outlet mounted next to the unit isrecommended. Secure all wiring as necessary. We recommend following ABYCguidelines for wire specifications and proper procedures.PUMP INSTALLATIONProper pump installation is important for pump operation. The SA-III uses a centrifugalpump, which is not self-priming. Air pockets caused by loops or descending lines fromone component to the other may cause pump problems. The pump is water cooled andlubricated; it must never be run dry doing so will destroy the pump. A separate throughhull fitting 3/4" or larger should be used. It should be as low in the boat as possible andaway from head and cockpit drains. A forward facing scoop will prevent problems if theunit is operating underway.A large seawater strainer should be mounted above the seacock.The pump should be mounted horizontally and should be higher than the strainer. Thedischarge should be on the top. Refer to the drawing at the back of this manual.WIRING THE PUMPA three-prong plug to the compressor unit connects the pump. Be sure this plugcannot get wet.15
