Using the Manual
This Owners Manual is intended to assist in the proper installation maintenance of the system. In order to ensure the
longevity of your humidier, the equipment should be installed as outlined in the Owner’s Manual. It is also vital to
establish a proper care and maintenance schedule. Please read and review this manual carefully and keep it for future
reference.

Receiving and Inspecting the System
• Lift only at the designated hand hold locations on the shipping container or fully support the unit from
underneath. A shipment may include one or more boxes containing accessories.
• Before opening the container, inspect the packaging for any obvious signs of damage or mishandling.
• Write any discrepancy or visual damage on the Bill of Lading before signing.
Note: CellarCool units are manufactured in the USA and tested prior to shipment.
Review the Packing Slip to Verify Contents
• Check the model number to ensure it is correct.
• Check that all factory options ordered are listed.
If any items listed on the packing slip do not match your order information,
contact CellarCool Customer Service immediately.
Check the Box for the following contents:
RECEIVING & INSPECTING THE SYSTEM

BEFORE YOU START
1. Inspect all components prior to installation. If damage is found, please contact your distributor or CellarCool
Customer Service at 1-855-235-5271.
2. It is REQUIRED to install a drain line to remove condensation from the Humidifier.
3. The system is intended for use in properly designed and constructed controlled rooms. Hire a professional
consultant with a valid contractor’s license to build your controlled room that is well insulated.
If you encounter a problem with your CellarCool unit, please refer to the Troubleshooting Guide on page 15. If you
have any further questions, concerns, or need assistance, please contact CellarCool’s Customer Service at 1-855-235-
5271. Please be sure all testing has been completed prior to contacting Customer Service. Please have your results
ready for your representative.

Unobstructed Airow
Unobstructed airflow to and from the system is critical for the Humidifier’s overall performance and life-span. A
minimum three-foot clearance (five foot is ideal) area is crucial.
Note: Avoid attempting to camouflage the unit. This will restrict airflow and thus the systems’s ability to work
efficiently.
Mounting the Humidier
The Humidier must be mounted at least 3’from the oor in order to achieve sucient humidity. Mounting the
unit high in the room will contribute to a consistently humid environment.
Door and Door Seal
An exterior grade (1 3/4”) door must be installed as a cellar door. It is essential that weather stripping is attached to all
4 sides of the doorjamb. A bottom “sweep”or threshold is also required. The door must have a very good vapor seal
to prevent the moisture in the cellar from escaping. One of the most common problems with a humidifier running
continually is due to the door not sealing properly.

Page 8 | 1-855-235-5271
ACTIVE HUMIDITY OPTION OVERVIEW
Use of the Active Humidity Option
Humidity may uctuate in the controlled room. The Active Humidity Option stabilizes the environment by adding
moisture when the relative humidity in the controlled room is becoming low. Using a humidistat and a water source,
the Active Humidity Option is able to regulate and establish a humid environment suitable for wine storage.
Note: The target humidity for most controlled rooms is between 50-70%.
General Active Humidity Option Recommendations
• Water source needs to have at least 40 psi.
• Water tubbing size: 1/4”O.D
• Water source should be tested for content and characteristics.
• In areas that are known to have hard water, the use of a Water-Softener System is required.
Note: Failure to install a Water-Softener or a Filtration system will allow an
excessive particle residue buildup and may lead to system failure.
• Even if the area is not known to have hard water, the use of a Filtration System (Particle Filter) is required.
• Use a Self-Piercing Saddle Valve as a simple connection to a water source.
• Clean or replace the Misting Nozzle every 12 months.

Failure to install the drain line voids the warranty.
To prevent mold from growing, allow the drain line to
hang above the water line.
Drain Line
The drain line tube is used to remove excess water from the humidier to a proper discharge location. It is important that
the drain line tube is properly connected and used to prevent leakage and other problems associated with excess water. It is
mandatory to install the drain line whether it leads through the wall and out of the controlled space.
Failure to use the condensation drain line tube will void the warranty on the unit.
WRONG: Drain line is under water.
INSTALLING THE DRAIN LINE
Use the barbed elbow as shown in Figure 12 to route the water to the discharge location below.
NOTE: Using the barbed elbow as shown
in Figure 12 is recommended.

Unit does not run/power up
Possible Cause Solution
Humidier is not plugged in Make sure the unit is plugged into an outlet
Power switch not on Turn unit on by pressing the power button on the control
Line voltage is incorrect rating for the system Check line voltage to make sure there is 110v/120v
Room at set point Lower set point
Humidistat not calling for humidifying Lower set point
Faulty Humidistat or wiring Call Customer Service at 1-855-235-5271
Humidity Levels are too Low
Possible Cause Solution
There is something blocking the supply and/or return air,
on the Humidier. Remove air ow obstruction

System Runs Constantly
Possible Cause Solution
Leaky door seal or poorly insulated cellar. Fix leaky door seal and insulate cellar in accordance with
this manual. (Page 9)
Unit leaks water
Possible Cause Solution
Humidier is not level Humidier should be level on the wall to prevent leaking.
Drain line clogged or kinked Check drain line to make sure water can ow freely.
Drain is clogged preventing water form escaping Disconnect drain and clear out, open access door and check
drain for blockage
Drain line does not have a downward slope Fix Drain line so there is a downward slope from the unit to the
drain.
