Installation |
Mount the KP pressure control on a bracket or on |
|
|
||
|
|
|
|
||
|
a completely flat surface. |
|
|
||
|
The pressure control can also be mounted on the |
|
|
||
|
compressor itself. |
|
|
||
|
In unfavourable conditions, an angle bracket |
|
|
||
|
could amplify vibration in the mounting plane. |
|
|
||
|
Therefore, always use a wall bracket where strong |
|
|
|
|
|
|
||||
|
vibration occurs. |
|
|
|
|
|
|
|
|
|
|
Al0_0001
If the risk of water droplets or water spray is |
|
|
|
||
present, the accompanying top plate should be |
|
|
used. The plate increases the grade of enclosure |
|
|
to IP 44 and is suitable for all KP pressure controls. |
|
|
To obtain IP 44, the holes in the backplate of the |
|
|
control must be covered by mounting on either |
|
|
an angle bracket (060-105666) or a wall plate |
|
|
(060-105566). |
|
|
The top plate is supplied with all units incor- |
|
|
porating automatic reset. It can also be used on |
|
|
units with manual reset, but in that case must |
|
|
be purchased separately (code no.: for single unit, |
|
|
060-109766; for dual unit, 060-109866). |
|
|
If the unit is to be used in dirty conditions or |
|
|
Al0_0007 |
||
where it might be exposed to heavy spray - |
||
|
||
from above or from the side - it should be fitted |
|
|
|
||
with a protective cap. The cap can be used |
|
|
together with either an angle bracket or a wall |
|
|
bracket. |
|
|
|
|
Al0_0008
If the unit risk being exposed to heavy water influence a better grade of enclosure can be achieved when mounting the product in a special IP 55 enclosure.
The IP 55 enclosure is available for both single unit (060-033066) and dual unit (060-035066).
