Maintenance Safety Requirement
Each component should be maintained by qualified technicians. Please contact competent
maintenance technicians in the event of leakage or breakdown. The safety devices should be checked
after each maintenance. Once leakage occurs, all the refrigerant in unit should be pumped out and the
leak point should be repaired and then charge the unit with suitable refrigerant according to the
nameplate. Some parts on unit can be separated and if the leakage occurs on these parts it is no need
to pump out all refrigerant in system.
Refrigerant type should be ensured according to the nameplate before charging, to charge incorrect
refrigerant will result in severe damages.
Ensure the lubricant type is equivalent with the technical document requirement when charging the
lubricant in maintenance.
Do not vent oxygen to the unit to avoid the violent reaction of oxygen and oil.
Do not exceed the max. allowed working pressure when unit operates.
Do not use oxygen for leakage inspection, only refrigerant or dry nitrogen is allowed.
Do not cut any component or pipes with flames or electrical soldering unless no gas or liquid refrigerant
is contained in the unit.
Toxic gas will be generated when refrigerant contacts with naked flame thus protection should be
provided for conveniently available for extinguisher.
Protection glass should be used for avoiding splashing of refrigerant to skin or eyes. Please use soap
and water to clean the refrigerant on skin and if refrigerant splashes into eyes by accident, use water to
wash eyes repeatedly and immediately go hospital.
Do not use naked flame or steam to heat refrigerant containing vessel otherwise over high pressure will
result in severe danger. Only mild temperature water can be used if heating refrigerant is needed.
Do not remove any cover or connection when chiller is operating or with internal pressure. Ensure no
internal pressure exist in unit before open any valve which may connected to atmosphere.
If any contamination, corrosion or mechanical damage exists in valves, do not try to repair or reset any
safety device. Please replace it when needed.
