Refrigerant

If applicable. See the installation manual or installer reference guide
of your application for more information.
NOTICE
Make sure refrigerant piping installation complies with
applicable legislation. In Europe, EN378 is the applicable
standard.
NOTICE
Make sure the field piping and connections are NOT
subjected to stress.
WARNING
During tests, NEVER pressurize the product with a
pressure higher than the maximum allowable pressure (as
indicated on the nameplate of the unit).
WARNING
Take sufficient precautions in case of refrigerant leakage. If
refrigerant gas leaks, ventilate the area immediately.
Possible risks:
▪ Excessive refrigerant concentrations in a closed room
can lead to oxygen deficiency.
▪ Toxic gas may be produced if refrigerant gas comes
into contact with fire.

1 General safety precautions
DANGER: RISK OF EXPLOSION
Pump down – Refrigerant leakage. If you want to pump
)
down the system, and there is a leak in the refrigerant
circuit:
▪ Do NOT use the unit's automatic pump down function,
with which you can collect all refrigerant from the
system into the outdoor unit. Possible consequence:
Self-combustion and explosion of the compressor
because of air going into the operating compressor.
▪ Use a separate recovery system so that the unit's
compressor does NOT have to operate.
WARNING
ALWAYS recover the refrigerant. Do NOT release them
directly into the environment. Use a vacuum pump to
evacuate the installation.
NOTICE
After all the piping has been connected, make sure there is
no gas leak. Use nitrogen to perform a gas leak detection.
NOTICE
▪ To avoid compressor breakdown, do NOT charge more
than the specified amount of refrigerant.
▪ When the refrigerant system is to be opened,
refrigerant MUST be treated according to the applicable
legislation.
WARNING
Make sure there is no oxygen in the system. Refrigerant
may only be charged after performing the leak test and the
vacuum drying.
▪ In case recharge is required, see the nameplate of the unit. It
states the type of refrigerant and necessary amount.
▪ The unit is factory charged with refrigerant and depending on pipe
sizes and pipe lengths some systems require additional charging
of refrigerant.
▪ Only use tools exclusively for the refrigerant type used in the
system, this to ensure pressure resistance and prevent foreign
materials from entering into the system.
▪ Charge the liquid refrigerant as follows:
If
A siphon tube is present
(i.e., the cylinder is marked with
"Liquid filling siphon attached")
A siphon tube is NOT present
▪ Open refrigerant cylinders slowly.
▪ Charge the refrigerant in liquid form. Adding it in gas form may
prevent normal operation.
Then
Charge with the cylinder upright.
Charge with the cylinder upside
down.
