Mechanical Start-Up
Procedures |
|
| |
Prior to start-up,
the as-installed drawings should be studied to
ensure a sound knowledge of the pipe runs,
ductwork,
isolating valves, bypass valves, shut-off dampers,
etc. Likewise, a study should be made of the
electrical power and
control philosophy to ensure an understanding of
total system operation and determine likely
sources of malfunction,
should they occur.
Reference to the relevant manufacturer’s technical
literature should be made to ensure adequate
familiarity with the
plant prior to start-up and operation. |
| |
| |
1) |
Ensure that all local
isolators are in the OFF position |
| |
|
|
| |
2)
|
Inspect all pipe work, etc. and
ensure that all system valves, (control,
isolating, bypass, strainers, drains, vents,
etc.) are at the correct settings |
| |
|
|
| |
3) |
Vent system if necessary |
| |
|
|
| |
4)
|
Ensure all system dampers,
(shut-off, volume control, fire/smoke,
bypass, supply and extract grilles, etc.) are
at the correct settings |
| |
|
|
| |
5) |
Ensure thermostatic controls
/ time-switches are correctly adjusted |
| |
|
|
| |
6) |
Ensure all safety devices
are in place |
| |
|
|
| |
7) |
Ensure all filter media is
serviceable |
| |
|
|
| |
8) |
Inform appropriate personnel
that plant start-up is imminent |
| |
|
|
| |
9) |
Switch ON electrical supply
to plant |
| |
|
|
| |
10)
|
Start plant using local
start arrangement (motor control centre,
inverter, etc.)
NB: where possible always
start plant on low load and check for
correct rotation |
| |
|
|
| |
11) |
Increase plant slowly to
operational speed, checking on electrical
load, noise, vibration, etc. |
