Figure 4-16 Removing an air filter (NetCol5000-C065) Figure 4-17 Removing an air filter (NetCol5000-C030/C032) NO TE For single-cabinet packaging and dual-cabinet packaging, the methods for removing air filters are the same.
NetCol5000-C(030, 032, 065) In-row Chilled Water Smart Cooling Product User Manual 4 Installation Figure 4-20 Checking the nitrogen pressure (NetCol5000-C030/C032) ----End Follow-up Procedure Check that thermal insulation foam is in close contact with the pipes, there is no crack in each cutting position, and the chilled water valve is tightly wrapped by thermal insulation foam.
● To replace the entire device, it is recommended that an active connector of the pipe is reserved for connection. ● NetCol5000-C030/C032 need to make the holes for the chilled water inlet and outlet pipes using a knife. Step 3 Clean the pipe and remove the thermal insulation foam from the pipe plug.
● In connecting the pipes, avoid violent shake. ● NetCol5000-C030/C032 need to make the holes for the chilled water inlet and outlet pipes using a knife. Step 3 Clean the pipe and remove the thermal insulation foam from the pipe plug.
