SEA FROST SHORE ASSIST SA-1 134a

THIS MANUAL IS SUPPLEMENTAL TO

THE SEA FROST R-134a ENGINE DRIVE MANUAL.

INSTALLATION INSTRUCTIONS

CONDENSING UNIT LOCATION AND MOUNTING

The design of the Shore Assist allows placement of the air-cooled unit in an enclosed

space such as a cabin locker, sail locker or engine room. Intake air should be drawn in

from the cabin area to insure the coolest, driest air supply. Standard 4" duct hose may

be used. Discharge does not need ducting if a vent in the area allows warm air to

escape. Intake ducting from the exterior of the boat will cause damp salt air to be drawn

in reducing unit life. This will also increase below deck moisture. The SA-I is extremely

quiet.

An unducted SA-I in a poorly ventilated small space will heat the air,

lowering the capacity of the unit and possibly causing damage by

overheating the compressor.

Service access and installation requires that the front and left end (inlet/outlet side) be

exposed. The duct hose will require 4 inches of clearance past the end of the SA-I.

Mount the Shore Assist level. The compressor is at the bottom. The unit may be

bulkhead or platform mounted. Pilot holes have been predrilled for the # 8 x 3/8" self-

taping screws and aluminum angle clips, included with the system.

INSTALLATION REQUIREMENTS

 Neither inlet nor outlet should ever be blocked.

 Provide for driest, coolest air for intake (top air port on housing.)

Total combined air duct length for intake and discharge should not exceed six feet. Only the intake needs ducting if the area is vented to allow warm discharge to escape. For intake or exhaust through a finished panel order an extra black flange grill. One part is shipped with each system. BEFORE BEGINNING THIS SECTION READ; "WORK HABITS", "TUBE HANDLING", "CUTTING and BENDING", and "SWAGELOK FITTINGS", in the SEA FROST ENGINE DRIVE INSTALLATION MANUAL.

WARNING: The SA-I unit is shipped under some nitrogen pressure. Before removing the caps on the Swagelok fittings, remove the screw caps on the service valve covers and depress the cores to vent any existing pressure. COMPRESSOR CONNECTIONS Working one line at a time, remove the Swagelok caps from compressor and condenser. Attach the union fitting bodies. This is a pre-swaged connection; See the Swagelok fittings text in the Engine Drive installation manual. Make up is 1/4 turn from wrench snug.

HANDLING", "PROCEDURES FOR WORKING WITH R-134a". Attach clean, purged gauges to the suction service port on the compressor. This is the blue capped tube stub. It is not necessary to connect to the high-pressure port when starting a new system. This is provided to aid in fault diagnosis. Evacuate the system and perform the "Evacuation Leak Check" and "Leak Check" as in the "R-134A Engine Drive Manual".

adjustment. Be sure valve is dry before final cap replacement. Operate for 30 minutes to confirm proper valve setting and operation. The valve may need to be cleared of dirt or chips if adjustment is not possible. With the compressor running, turn the valve adjustment knob clockwise about 3 turns momentarily then back to the proper setting. Do not leave the valve in the open position allowing high backpressure, as this may cause the compressor to overload.

the high side pressure will be 80 to 135 psi depending on the air temperature (50 to 95 degrees F.) through the unit. Almost immediately upon start up the valve body will begin to frost. THE THERMOSTAT The Shore Assist thermostat is variable. Turning the knob fully counterclockwise turns the unit "OFF". The one snowflake position is the warmest setting. The fully clockwise setting at three snowflakes is the coldest.

THERMOSTAT CALIBRATION INSTRUCTIONS Note: Be sure that the unit is operating properly before making any thermostat adjustments. The sensing bulb must be in excellent thermal contact with the plate or block. The range of this control may be changed. To access the adjustment screw, remove the four mounting screws on the thermostat panel. Tip the panel forward and remove the protective tape to expose a slot in the case. Make the adjustment with a torx or small phillips head screwdriver. Make small adjustments.
