DISCHARGING THE SYSTEM
Before the connections or components can be disassembled, the refrigerant must be recovered with a reclaiming machine. Connect a gauge set to the suction access port and slowly recover the refrigerant. Keep the pressure under 20 psi. Do not loosen any connections until the system holds 10 inches of vacuum for 10 minutes.
To discharging an overcharged system; recover at the same 20 psi rate for a minute at a time between test operations. Be sure the gauge hand wheel is off before starting the compressor.
TROUBLESHOOTING
The most common problems that can occur in a SEA FROST DC 5000 system are:
1.Low voltage which can cause premature motor brush wear and commutator damage.
2.Loss of refrigerant charge resulting from leaks.
3.Moisture or dirt plugging the valve.
4.Compressor malfunction due to loss of refrigerant charge.
5.High pressure cut out from loss of water flow.
6.High pressure cut out from over charging.
STEP 1. Gather information as to the nature of the problem before operating the system. A leak often leaves a trace of oil. Inspect fittings, components, and tubing for wear, corrosion, and chafe. Do not operate the compressor until trouble is
corrected.
High pressure
For further troubleshooting, attach purged gauges to access service ports or observe the temperature of the lines. See pages
a)If the icebox and SEA FROST plate is warm and pressure readings are below 50 psi with the compressor off (in 50 degree F or higher ambient conditions), pressurize the system with
