What to do if no input signal is detected for Daikin Fan?
If your Daikin Fan shows no input signal or the signal is out of range, check the input signal connections. Make sure that the signal is within the acceptable range.
What to do if Daikin Air Handlers Multi-Steam discharges water inside the duct or AHU?
If your Daikin Air Handlers Multi-Steam is discharging water inside the duct or AHU, several factors could be at play. First, check if the steam supply line is adequately insulated; if not, insulate it. Second, ensure the steam supply line is properly drained and sloped according to instructions. Third, verify that the Multi-Steam condensate drain isn't blocked and that the drain line is correctly sloped. Fourth, confirm the Multi-Steam is properly pitched as per instructions. Finally, inspect the gasket on the Multi-Steam collapsible for leaks and replace it if necessary with gasket (p/n SP 6867).
