6.5.1 Option H1
Anchoring the machine
➤ Use appropriate fixing bolts to anchor the machine.
Further information Details of the fixing holes are contained in the dimensional drawing in chapter 13.3.
6.5.2 Option K2
Connecting the cooling water
➤ Take the electrochemical series into consideration and choose suitable materials for water
connections.
➤ Keep the effect of pressure surges on the coolers as low as possible.
➤ Install an expansion tank to act as a pulsation damper if pressure surges cannot be avoided.
➤ Avoid a low inlet temperature for the cooling water as it can cause condensation. If required,
contactKAESER for suitable insulation measures.
Temperature-controlled cooling water supply systems, to which numerous machines are connected,
regulate the water flow rate according to the difference in temperature between the supply and the
return water. Individual machines may not receive an adequate flow under this system. Breakdowns
are the result.
➤ KAESER can advise on how to ensure the cooling water supply via suitable control valves.

1. The user is to provide the following fittings:
■ Dirt trap with max. 0.1 mm strainer mesh
■ Shut-off valves 10 and connection ports 12 for maintenance and venting
■ Pressure relief valve 17 to prevent build-up of excessive pressure.
Blow-off pressure and capacity are governed by the user's installation design. The technical
specification of the cooler must be taken into account.
2. Connect the cooling water lines to the fittings.
3. Open the shut-off valve on the cooling water outlet A .
