Evaporative cooling Worn pad and sign of Deteriorating Inspect the evaporative cooling pads and if required ideally replace them within 1-2 years to avoid clogs of dirt ACTION AT THE TIME OF FAILURE When the adiabatic cooling solution fails to operate, close the water supply manual ball valve to avoid over flow. To avoid failure recurrence, use caution for the following. (1) To avoid recurrence of the same failure, execute reliable failure diagnosis and identify the true cause before starting a repair. (2) When the piping is to be corrected, be sure to close the water supply and disconnect the solenoid valve from the power supply. Disconnect is to be undertaken by qualified persons only. (3) Always check and if necessary, shut down power and restart the unit. CAUTION: If any damaged electrical components are identified during inspection isolate case power and contact service contractor. PAGE 29 2HP OUTDOOR REFRIGERATION UNIT- HUSSMANN... -
