- After coolant (water + glycole) charge operation, it is necessary to vent the unit. Use venting valve installed on
top of MCH coil to do this operation.
5.1.5 Free cooling purge valve related
The purge valves locate at four corners of the free cooling MCH are used for air purging and water purging. The below
instruction is defined to protect the purge valve from deformation and/or failure.
After dismounting the cap, please refer to the below:
- Check and clean the screw if there is dust and debris on screw’s surface
- Check the rubber o-ring in the cap and make sure that it is in the cap and in the right position
- Screw the purge valve with one circle by hand and make sure the screw match is well.
- Clockwise screw the purge valve with torque wrench. Make sure the torque should be applied around the screw
axis. The eccentric torque might damage the screw.
- Operation torque:
o The recommended torque value to install the cap is 5 Nm
5.1.6 Operations in case of failure
In case of free cooling coil breakage,
1. Empty the unit
2. Close valve 1 and valve ”d” (see Fig. 28) In case of glycol free unit, close the two valves ”d” (see Fig. 28).
3. Isolate the failed coil/coils which need to be replaced
4. Close the coil so to avoid air entrance inside it and any trace of humidity
5. Pressurize all coils with nitrogen at 1-2 barg
The purge valves protrude from the machine’s envelope.
Pay attention to not let the purge valve be impacted during transportation and installation process.
Please note that free cooling MCH coil cannot be exposed to open air for too long due to possible
humidity entrance.
DAE cannot be considered accountable for any failure of flexible hoses which connect free cooling
coils to stainless steel main manifolds.
