Step 2 Connect the pressure inlet tube.
●
Cold aisle containment: Connect a pressure inlet tube to the + mark and route
it to the aisle through the hole on the top of the cabinet. Ensure that the
pressure inlet faces downwards. Connect another pressure inlet tube to the –
mark and route it to the cabinet top through the hole atop.
●
Hot aisle containment: Connect a pressure inlet tube to the + mark and route
it to the cabinet top through the hole atop. Connect another pressure inlet
tube to the – mark and route it to the aisle through the hole on the top of
the cabinet. Ensure that the pressure inlet faces downwards.
Step 3 Connect the cable terminal of the differential pressure sensor to the DPT terminal.

3.13 Checking After Installation
1. Check the drainpipes are securely installed, clear, free of leakage, and not over
bent.
2. Check that the chilled water connector joints have been tightly wrapped with
thermal insulation foam, and no metal or hose is exposed.
3. Check that the liquid level detector is horizontal, that the water pan is free of
foreign matter, such as residual cables and thermal insulation foam, and that
the cables are secured bound and not in the water pan.
4. Check that the distance between two chilled water pipes outside the cabinet
is sufficient (recommended distance: longer than 25 mm), the hose is tightly
wrapped with insulation foam, and that junctions are secured using glue.
5. Check that the pipe lines have completed pressure preservation and air
tightness test.
6. Check that the needle valve plugs and the nuts are tightened.
7. Check that the cabinet is grounded.
