● General warnings in operating this unit are mentioned in this section.
● While specific details are mentioned in each particular clause.
◆ When performing recycle operation, choose a location that has good
ventilation. In enclosed areas, mechanical ventilation should provide at
least four air changes per hour or the unit should be used at least 0.5m
above the floor.
Leakage of gas without sufficient ventilation may cause suffocation due to lack of
oxygen.
◆ Do not recycle flammable gas(hydrocarbon or hydrocarbon material) .
If anything other than fluorocarbon [Ammonia, hydrocarbon (propane,
isobutene,) ,etc.] gets into the unit, it may cause an explosion.
◆ Burning refrigerant creates a deadly poisonous Carbon Oxy-Chloride
and inhaling this gas is very dangerous.
There should be absolutely no flammable material near the working area and the unit
must be operated under good ventilation.
◆ Absolutely no smoking or any open flame during the work in process.
Cigarettes may create Carbon Oxy-Chloride and cause a fire.
◆ Use safety glasses and leather hand gloves during operation or when
disconnecting hoses.
Refrigerant gas may cause frostbite or damage your eye sight.
◆ Do not close the valves of the unit and the hoses when they are full of
liquid refrigerant.
◆ Do not operate or store the unit at temperature above 35℃ .
When the recycle operation is done, operate the purge procedure to prevent the liquid
refrigerant from expanding which may cause an explosion.
◆ Use a scale to monitor the amount of refrigerant in the cylinder.
Stop filling at 80% or less as the cylinder may explode in the event of full filling.
◆
Use ONLY authorized refillable refrigerant cylinders. The unit requires
the use of recycle cylinders with a minimum working pressure of 27.6
bar (2.76 MPa/400psi).
Do not exceed the working pressure of the recycle cylinder.
◆ Do not operate the unit with wet hands or in the rain.
Handling the electric plug and power switch with wet hands or in the rain, may cause
electric shock.
◆ Make sure to have the unit grounded (earthed).
If the unit is not properly grounded, it may cause electric shock.
◆ Check the electric power plug regularly to make sure of no damage.
Always have the plug inserted firmly.
When the plug has dirt or oil or the connection is incomplete, it may cause electric shock
or fire.
