Sea Frost 372 ROUTE manual Installation Requirements For Condensing Unit, Pump Installation

Service access and installation requires that the front, left end (inlet) and back (condenser) air outlet be exposed. A duct hose will require 4 inches of clearance past the end of the cabinet.

Mount the Sea Frost BD level, (the compressor is at the bottom). The BD may be platform mounted. Two holes have been drilled through the bottom for screw mounting to a shelf or bulkhead. If using the bulkhead mount bracket kit, follow directions supplied with the kit.

INSTALLATION REQUIREMENTS FOR CONDENSING UNIT

•Never block air inlet or outlet.

•Provide for driest, coolest air for intake.

•Total air duct length for intake should not exceed six feet.

•Make sure installation location is vented to allow warm discharge to escape.

•For intake through a finished panel, order black flange grill.

PUMP INSTALLATION

For proper operation, please understand pump installation before beginning. The BD water-cooled uses a magnetically coupled centrifugal pump. It is not self-priming and must be well below the water line. Air pockets caused by loops or descending lines from one component to the other may cause pump problems. This pump must never be run dry. It is water cooled and lubricated. The wet end may be destroyed if it is started dry. Using a different pump will defeat any energy gain.

A separate through hull fitting 1/2" or larger should be used. It should be as low in the boat as possible and away from head and cockpit drains. A forward facing scoop will prevent problems if the unit is operating underway.

A large seawater strainer should be mounted above the seacock.

The pump should be mounted horizontally. It should be higher than the strainer. The discharge should be on the top. A 3/8” hose should feed up hill to the BD unit. This should connect to the lower water fitting. From the upper water fitting a 3/8” hose should connect to a through hull above the water line.

Refer to the pump installation drawing at the end of this manual.
