Tech found the drain for the larger gas pack (kitchen) was completely clogged with algae and partially obstructed by a zip tie. Tech used water hose and shop vac to clean and clear drain trap and drain line. Partially removed drain pan from package unit to use shop vac and water hose to completely clean drain pan. Reassembled drain and closed up unit. System is back draining correctly. Manager on duty also reported front gutter dripping. There are no HVAC drains near that location. There is a tree that has likely clogged the roof gutter with leaves. Tech recommends cleaning gutter and sealing seam in the bottom of gutter where it drips. Not HVAC related.

Humidistat is lit up and reports humidity setpoint is satisfied. Humidistat is powered from dehumidifier. No batteries. Dehumidifier is operational. Said registers in
