12. If the required booster start delay is greater than 30 seconds, use the SEM to edit and save the
original configuration set uploaded from the iH (the set saved as, for example, "iH600"): set
the BOOSTER START DELAY to the required booster start delay time.
13. Use the SEM to download the original configuration set (with file name, for example, of
"iH600") to the iH system.
14. Start up the iH system again and at the same time start the stop-watch. Watch the pressure
gauge in your inlet pipeline. The HCDP pump will start and the pressure will start to reduce.
After the booster start delay time, the HCMB pump will start (at an inlet pressure of
approximately 5 mbar, 5 x 10
2
Pa):
•
If the pressure increases or does not decrease any further when the HCMB pump starts,
the HCMB pump-motor terminal-box is incorrectly wired: immediately shut down the iH
system, correct the electrical wiring (refer to Section 3.16.2), then repeat this procedure
from this step (Step 14) again.
•
If the pressure continues to decrease after the HCMB pump starts, continue at Step 15.
15. After you have commissioned the iH system:
•
If you want to continue to operate the iH system, refer to Section 5.
•
Otherwise, shut down the system: refer to Section 5.10.
3.21 Install the disconnect box (accessory)
The following sections provide the installation of the disconnect box to your system. The
disconnect box general arrangement is shown in Figure 1-9.
3.21.1 Unpack and inspect
Remove all packing materials and protective covers and check the controller. If the controller
is damaged, notify the supplier and carrier in writing within three days; state the item
number of the controller together with the order number and suppliers invoice number.
Retain all packing materials for inspection. Do not use the controller if damaged. Check that
the package contains the following items:
