R41 0A contains no chlorine, does not destroy the
ozone layer and so does not reduce the earth's
protection against harmful ultraviolet radiation. R41 0A
will contribute only slightly to the greenhouse effect if
released into the atmosphere.
• Since design pressure is 4.0 MPa or 40 bar (for R407C
units: 3.3 MPa or 33 bar), the thickness of pipes must be
greater than previously. Since R41 0A is a mixed
refrigerant, the required additional refrigerant must be
charged in its liquid state.
(If the system is charged with refrigerant in its gaseous
state, due to composition change, the system will not
function normally). The indoor unit is designed for R41 0A
use.
components and parts may result in the unit falling, water
leakage, electric shocks or fire hazards.
• Explain the users how to operate the air conditioner's each
function properly and how to regulate the temperature. Ask
them to operate personally while reading the operation part
