Sign off on the daily compressor unit check

Warning: This procedure requires trained personnel with PPE!

EZ-CAL High pressure cut-out check valve test block

Is the EZ-CAL test block installed on the package?

Is the pressure transducer wired to the Quantum HD controller?

Is the tubing run to the compressor discharge connection?

Is the HPCO fully open to the discharge pressure source in the RUN position?

Is the external source connected directly to the HPCO in the TEST position?

Is the function of the HPCO and pressure setting confirmed by application of external pressure?

WARNING: Failure to enter skip frequencies could cause catastrophic compressor failure or severe compressor damage and result in serious injury or death.

Check for excess vibration and skip frequencies anytime unit operating conditions change

Decrease the VFD speed by 100 rpm increments and check for elevated energy

Enter the vibration meter reading

Does the vibration meter reading meet or exceed one inch per second?

If the vibration meter reading meets or exceeds one inch per second, skip that frequency range in the microprocessor for the VFD

Enter the identified frequency range to be skipped

Set the skip to as narrow a frequency band as possible, only making it wider until full range is accommodated

Warning: Use of filter elements other than Frick may cause warranty claim to be denied.

Is a single oil filter installed?

If a single oil filter is installed, push [STOP] key on microprocessor panel to shut down unit, then open disconnect switches for compressor and oil pump motor starters.

Are dual oil filters installed?

If dual oil filters are installed, open the outlet, then inlet service valves of the standby filter.

Warning: Open inlet service valve slowly to prevent a sudden pressure drop which could cause an oil filter differential alarm.

Close outlet then inlet service valves of filter being serviced.

Open bleed valve and purge pressure from the oil filter cartridge.

Remove the plug from the bottom of the filter canister and drain the oil. Remove the canister cover and discard the gasket. Remove the screws securing the filter assembly. Pull the filter assembly from the canister and discard the gasket and the element.

Check coupling: Check bolts, shim packs, center inserts, keys, and all bolt torques.

Check alignment: Refer to 070.210-IB for foot mounting alignment.

Suction and discharge flange bolts: Verify tightness of bolts on suction and discharge flanges. See Table 13 for torque requirements.

Check electrical connections: Check and torque all terminals in the processor and starter panel per the specification posted in the enclosure.

Check sensor calibration: Check calibration of slide valve, slide stop, pressures and temperatures. Calibration should be conducted with NIST certified devices.
