Installation
Connecting the com-
pressor to the com-
pressed air network
– Connect the compressor to the compressed air network or a compressed
air receiver.
For this, use a BOGE high pressure hose.
Connecting the cooling
water (optional acces-
sory)
The pipework for the cooling water circuit in the compressor was fully installed
in the factory.
Only the following work must be performed during installation:
1. Check, whether the water supply has the required data, see “ Water con-
2. and whether the cooling water quality is adequate (see " Cooling water
3. Connect the cooling water supply and discharge line to the water supply
(cf. dimensioned drawing).
The following additional components must be provided by the customer when
installing the water cooling unit:
–
Dirt trap
The dirt trap at the cooling water inlet protects the cooling units against sed-
iment collecting. Pore width: max. 0.02 inch.
–
Expansion vessel and safety valve
NOTICE!
Do not install a non-return valve in the pressure line.
The compressor is already equipped with a non-return valve.
WARNING: Risk of injury!
Risk of injury due to pressurised water when connecting the cooling water
system!
Close external water mains prior to connection!
The connection must only be carried out by authorised and qualified person-
nel!
WARNING!
If the stop valves in the supply and discharge lines are simultaneously closed
in a closed cooling system, an enclosed chamber will result. If the water
heats up in this room, it will expand and the pressure will increase.
Install an
expansion vessel
and a
safety valve
to prevent damage to the
cooling units.
