Cleaning The Filters; Cleaning The Condensate Drain System; Cleaning The Humidifier (Optional); Heating Coil - Wine Guardian DP25 Installation, Operation And Maintenance Manual

Cleaning the Filters

The condenser coil is provided with a reusable, washable air filter. The filter protects the coil from
becoming coated or plugged by dust. Frequency of cleaning the filters is based on the amount of dust
or dirt generated in the cellar or basement.
1. Remove the duct collar on the inlet end of the unit.
2. Remove the filter covering the face of the coil.
3. Wash it under warm water.
4. Shake off excess water.
5. Inspect and clean the face of the coil.
Sharp edges are present on the fins and coils.
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 duct on the evaporator inlet.
3. 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 duct collar.
7. Plug in the unit and restart.

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

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.
