Pretest &
Functionally Test All Equipment
to be Commissioned & Correct Deficiencies
Inspect
and pretest all major equipment before installation is complete,
to discover serious defects that may affect the commissioning
and occupancy schedule. Finalize testing once installation
is substantially complete, but before full start-up.
Testing
should include proper operation of:
- all
motors;
- all
major controls, servos and actuators;
- pumps;
and
- other
electrical and mechanical devices.
- PV
and water solar collectors
Check
for correct voltage, starting and operating current, shaft
speed, pressure, correct rotation, full travel and positive
closure of dampers and valves, etc. Check electrical controls
for response to sensors.
All
pressure vessels and piping should be pressure- and leak-tested
just prior to completion of installation to determine any
defects in joints, welds, etc. Ensure that each pretest
and test is fully documented, and the records given to the
commissioning coordinator.
Caution
- Ensure
lock-out and tagging procedures are rigorously followed
for motors and electrical circuits during testing to maintain
safety.
