3.2.3
Acceptance Tests
Upon completion and prior to acceptance of the work, the Contractor shall
perform pre-operational checkout, calibration and adjustment of system
components to ensure and demonstrate stable, accurate, reproducible, energy
efficient operation and optimum performance. Systems shall be operated for
[48] [_____] hours after all major corrections have been made. If tests do
not demonstrate satisfactory system performance, deficiencies shall be
corrected and system shall be retested. Prior to acceptance, service valve
seal caps and blanks over gauge points shall be installed and tightened.
3.3
CLEANING AND ADJUSTING
Equipment shall be wiped clean, with all traces of oil, dust, dirt, or
paint spots removed. System shall be maintained in this clean condition
until final acceptance. Bearings shall be properly lubricated with oil or
grease as recommended by the manufacturer. Belts shall be tightened to
proper tension. Control valves and other miscellaneous equipment requiring
adjustment shall be adjusted to setting indicated or directed.
3.4
DEMONSTRATIONS
Demonstrations shall be conducted for the operating staff as designated by
the Contracting Officer. Demonstrations shall start after the system is
functionally completed but prior to final acceptance tests. Demonstrations
shall be under the direction of a registered professional engineer who
shall attest to installed systems and equipment compliance with the
requirements of the contract documents. Demonstrations shall include
operation of systems equipment and controls through normal ranges and
sequences and simulation of abnormal conditions. Each device shall be
caused to function manually and automatically in accordance with its
