Before Use
The SCU is operated via the SCU control panel (see chapter
5 Control Panel Description
).
9.5.1
Inflation
Ensure that SCU is not covered and air flow around SCU is not obstructed in order to avoid overheating.
Connect mains cable of SCU to suitable mains socket.
For Mains Operation (For Accumulator Operation see chapter 10):
Switch on SCU using bigger power switch on side of SCU.
The SCU will take 30 s for the initialisation. After that the mattress will start to inflate.
After activation of SCU the mode set before turning off starts again if this previous mode was used for 15 minu-
tes or more. This settings is saved in SCU unless backup memory is completely erased. After that default mode
is set back to APT mode with pressure level 3.
Inflation Mode CLP:
When CLP is set, indicator
14
and indicator
3
will keep flashing during the initial inflation.
Then CLP indicator
14
will light solid and indicator
3
will flash while pressure is adjusted to the set pressure level.
When the set pressure level is reached, indicator
14
and indicator
3
will remain solid on.
When the inflation process is finished:
Check if safety straps of mattress cover are too tight and correct if necessary.
If indicator 7 (see Control Panel picture) flashes during inflation process and audio alert signal sounds:
Check if air pipe is connected correctly.
Fig. Switching on SCU
To switch off SCU:
Switch off SCU using Mains and Accumulator power switch on
side of SCU.
Disconnect mains cable from mains.
NOTE When switched on, the SCU will return to the last mode (APT) or
CLP) and pressure setting. The mode and pressure settings are only valid
when the SCU has been running with these settings for more than 15 minu-
tes.
During the inflation process:
Indicator
14
or
4
flashes white, depending on the last mode setting. The
inflation process takes 15 minutes at most.
Inflation Mode APT:
When APT is set, indicator
4
and indicator
3
will keep flashing during the
initial inflation.
Then APT indicator
4
will light solid and indicator
3
will flash while pre
-
ssure is adjusted to the set pressure level.
When the set pressure level is reached, indicator
4
and indicator
3
will
remain solid on.
