Cleaning The Condensate Drain System; Flushing A Water Regulating Valve - Water-Cooled Models Only; Cleaning The Humidifier (Optional); Heating Coil Option - Wine Guardian D050V Installation, Operation And Maintenance Manual

5. Inspect and clean the face of the coil.
6. Reinstall the filter.
7. Replace the duct collar.

Cleaning the Condensate Drain System

The condensate drain system traps dust and dirt. Clean the drain system once a year.
1. Shut off the rocker switch and unplug the unit.
2. Remove the grille or duct on the evaporator inlet.
3. Remove the filter and inspect the drain pan under the coil.
4. If drain pan appears soiled, pour some hot water mixed with liquid bleach (diluted
solution) along the length of the pan to flush the dirt down the drain tube.
5. Continue this treatment until the drain appears clean and free of dirt.
6. Reinstall filter and grille or duct collar.
7. Plug in the unit and restart.
Flushing a water regulating valve – water-cooled models only
To clear any sediment that may accumulate,
valves may be manually flushed by inserting
screwdrivers under both sides of the main spring
and lifting upwards to flush the valve. Manual
flushing does not affect valve adjustments.

Cleaning the Humidifier (optional)

I
f the unit was furnished with a humidifier it
requires periodic maintenance. Follow the instructions in the humidifier guide.

Heating Coil Option

The heating coil is located between the evaporator coil and blower inside the transition duct. It
contains the heating element and high temperature limit switches. The heating coil is wired to work
in conjunction with the thermostat. Since the thermostat prevents the heating and cooling circuits
from being energized at the same time, no additional power wiring is needed. We do recommend
using the AUTO mode on the thermostat so it can switch from heating to cooling automatically. If
using either the heat or cool only mode, the thermostat will not switch automatically.
No additional maintenance is required for the heating coil. To test the heating coil operation, set the
thermostat on HEAT and set the temperature above the cellar temperature. The supply air temperature
should rise above the return air temperature by an amount shown in the specifications.
