Carrying out the tests and check program listed below will extend the life of the equipment and avoid possible breakdowns.
Please Note: it is of utmost importance the compliance with Regulation (EC) No 842/2006, regarding mandatory regular
leakage-check program, as described in Section 2 of this Operation and Maintenance Manual.
Check mechanical working of the compressor . Control the absence of metallic vibrations and not too high noises and
temperatures on the compressor head during running to verify its regular working.
Check the operation of the fan.
Check the electrical alarm systems and controls.
Check the filling of the tank (visual level). If the system is filled with a glycol-mix, refill only with the same mix. Only water will
reduce the concentration of glycol.
Check that pressure, flow rate and temperature values of the hydraulic circuit are included into the limits indicated on the
machine label. For closed loop system (PWW) pelase verify periodically the pressure indicated on the manometer (with
pump OFF) to verify the precharge value. If it’s necessary a refill please follow the start up procedure in Appendix A2.
