The high/low pressure switch, where present must be tested with the
machine “closed”, reading the high pressure circuit pressure on the machine
control panel.
In case of machines with the cooling circuit compartment not closed by fra-
mework, the high/low pressure switch must be tested by standing in front
of the machine panel where the control panel is located, remaining distant
and not exposed to the under pressure parts of the cooling circuit.
CLEANING COIL MICRO-CHANNEL
Keep surfaces clean battery mirco-channel is critical to maintaining the refrigeration systems at optimum performance levels. Dirt, grease, oil, and other
foreign material must be removed periodically from the surface of the battery according to the following recommendations.
REQUIRED ELEMENTS:
• Personal protective equipment
• Hot water
• High-pressure washing
PROCEDURE:
• Use a detergent-type aqueous / spray- with a basic pH of less than 10.5 when mixed at the concentration recommended by the detergent
manufacturer. Silicied formulations are preferred. The use of inadequate detergents can damage the surface of the battery.
• Mix the detergent with warm water according to manufacturer’s instructions. For best results, the temperature of the detergent mixed must be
118,4 °F.
• Use a high-pressure washer with a large cast and enough force to remove all foreign material. minimizing cleaning time. Proceed with care to avoid
damage and possible wear of the ns.
• Leave the cleanser on the batteries to the amount of time prescribed by the manufacturer’s instructions.
• Rinse thoroughly with water all the cleaning material from the battery and surrounding equipment, including the fan and carpentry.
