Installation - Operation - Maintenance manual (IOM) • AIR COOLED CHILLERS & SPLIT UNITS - 1106-E
• 6 •
ƒ All installation parts must be maintained by the personnel in charge, in order to avoid material
deterioration and injuries to people. Faults and leaks must be repaired immediately. The authorized
technician must have the responsibility to repair the fault immediately. Each time repairs have been
carried out to the unit, the operation of the safety devices must be re-checked.
ƒ Follow guidances and recommenadations given in safety and machine standards such as EN378, ISO5149,
etc
ƒ Do not use oxygen to purge lines or to pressurize a machine for any purpose. Oxygen gas reacts violently
with oil, grease, and other common substances.
ƒ Never exceed the specified maximum operating pressures. Verify the allowable maximum high- and low-
side test pressures by checking the instructions in this manual and the pressures given on the unit name
plate.
ƒ Do not use air for leak testing. Use only refrigerant or dry nitrogen.
ƒ Do not unweld or flamecut the refrigerant lines or any refrigerant circuit component until all refrigerant
(liquid and vapour) has been removed from chiller. Traces of vapour should be displaced with dry air
nitrogen. Refrigerant in contact with an open flame produces toxic gases.
ƒ Do not siphon refrigerant
ƒ Avoid spilling liquid refrigerant on skin or splashing it into the eyes. Use safety goggles. Wash any spills
from the skin with soap and water. If liquid refrigerant enters the eyes, immediately and abundantly flush
the eyes with water and consult a doctor.
