Congratulations on purchasing an Opti-Mist+ Adiabatic ® A unit-mounted interlock authorizes the system to run. A Pre-Cooling System from RefPlus . Your system has been ® fluid temperature and an outside temperature sensors vary thoroughly inspected and leak tested before shipment to the required USGPM to cool the air before entering the heat ensure peak performance.
Figure 2 Piping connections installation and sent back to RefPlus. This is to insure proper follow-up from the manufacturer and to activate the warranty. This form is also available at the end of this All piping should have a minimum slope of 1/4"/12"...
WATER PRESSURE ADJUSTMENT FLAT SLAB MODELS “V” MODELS “W” MODELS Figure 4 Proper nozzle orientation 6. WATER PRESSURE ADJUSTMENT When pump outlet valve (3) is closed, pressure should not be above 85 psi. If you are not able to meet this outlet pressure Inlet water pressure: and if it is too high, lower the inlet water pressure (1) as close Water pressure is adjusted through a regulating valve on the...
Refer to the Controller's Programming Manual to complete the RefPlus recommends a monthly check of the spray nozzles configuration and adjustments, such as the temperature and the water distribution piping for damage and uniform settings, system selection, etc.
TROUBLESHOOTING 9. TROUBLESHOOTING PROBLEM POSSIBLE CAUSES POSSIBLE CORRECTIVE STEPS Check if Status on Main Status screen is ON. If not, switch the system ON and check for alarms and continue troubleshooting. Check Offsets. They should be at zero during normal operation or can be used to simulate FT and OT to create a Cooling demand.
