Normal Noises When Functioning; Temperature Control - Electrolux ENB3660 Instruction Book

Normal noises when functioning

1. Temperature control.

May cause clicking sounds when the system is connec-
ted or disconnected.
2. Cooling system.
The injected cooling gas may produce a gurgling sound
while passing through the tubes.
3. Motor.
May cause a humbing noise and/or slight bumping.
4. Insulation.
The material used has a tendency to slightly increase
noise levels, however it allows for much better insula-
tion and a lower energy consumption.
5. Fans.
You may occasionally hear the fans working. This is
nothing to worry about. The fans are simply helping the
air to circulate more effectively.
