of the liquefier unit
WARNING – danger of intoxication!
If large amounts of R410A escape into the
room atmosphere, fumes are produced which
can lead to intoxication or irregular heartbeat
which could be fatal.
Take immediate safety precautions in case of
heavy leakage from the coolant circuit!
Pipe connections (liquefier unit):
The pipe connections on the liquefier unit consist of two
valves
1
and
2
(see
fig. 6.5
). The valve
2
of the sup-
ply line has an additional maintenance connection
6
with
Schrader valve. The pipes
3
to be laid by the customer
must be fitted with a union nut
4
and equipped with a
flanged end
5
.
NOTE – nature of the flanged end!
The wall length of the socket should be evenly flanged.
Make sure that no chips, dust or other foreign bodies fall
inside the pipes because the coolant circuit could otherwise
be blocked at the level of the hair pipe. This would result
in blockage of the system or seizing of the compressor
of the liquefier unit.
Coolant volume:
The coolant volume of 1050 g is sufficient to supply a
piping system (supply and return line) of a total length
of 10 m. If the piping system exceeds this dimension, an
additional 15 g of coolant (R410A) for every further meter
of pipe laid must be added into the circuit. The coolant
is added at the maintenance connection
6
through the
Schrader valve.
Checking for leaks:
To check for leaks, pressure is applied to the supply line
(liquid gas pipe) and to the return line (suction gas pipe)
for approx. 30 minutes.
