  • Page 4 Standard Design Features Our Large Air Handler cooling systems use a common approach to optimize compressor size, fin spacing and coil size, and blower air fan. The goal is to maximize cooling power without stripping humidity and maintain consistent temperatures. Our Large Air Handlers offer a wide array of modifications, such as a networkable controller, integrated humidifier and integrated heater.
  • Page 5 Refrigeration System Components Easily accessible components in the Evaporator include: thermal expansion valve, pump-down solenoid valve, suction line service access port, and condensate overflow emergency shut-off float switch. Condensing Unit components include an electronic controller for low pressure control cut-in/cut-out adjustment, mounted filter drier and sight glass, and liquid/suction service valves.

    Electric Heat For wine cellars that are exposed to conditions below 55°F temperatures, CellarPro Air Handlers can be configured with optional integrated heaters to provide 3kW (10236 BTUH) of heat. The unit incorporates a factory installed nichrome wire heater.
  • Page 7 Ecobee Networkable Thermostat The cooling unit is compatible with most 24V Networkable Thermostats (sold separately). We offer the Ecobee SmartThermostat Pro (P/N 31453) which incorporates temperature control and humidity display in an attractive, backlit, easy to install wall- mounted unit. Features include: ...

  • Page 15: Installation Instructions

    Installation Instructions  Unit Clearance: The evaporator supply and return openings should be located at least 24 inches from any obstructions for proper airflow on non-ducted units. The left side electrical enclosure and right side access panels should be located at least 24 inches from any obstructions for service access. Reference the Condensing Unit Dimensional Data drawing for required condensing unit clearances.
  • Page 16 Thermostats (NT (sold separately)). The Evaporator is also configured with a unit- mounted temperature display that provides troubleshooting, operational safety controls , defrost cycles, and freeze protection. Compatible NT CellarPro has tested and approved the following NT brands/models:  Ecobee4 Pro  Nest ...
  • Page 17  Compressor Minimum Off Time: If this setting is disabled by default, it must be enabled, with a minimum off time for CellarPro product s of 3 minutes.  If the Thermostat allows high/low temperature alarms, we recommend the following settings: 40°F (Low) and 70°F (high).
  • Page 18  Humidity Management: The humidity level in the cellar can be maximized by allowing the cooling fans to run at the end of every cooling cycle. The unit is equipped with an Off-Delay relay in the electrical enclosure and can be adjusted from 12 -390 seconds. The recommended setting is 180 seconds (3 minutes).
  • Page 19 Optional Integrated Humidifier General Description The humidifier is designed to increase the cellar humidity level above a 50% threshold where wine bottle storage is more stable for preserving the corks. It is intended for situations where the ambient relative humidity of the air surrounding the cellar is insufficient to maintain the desired humidity level inside the cellar, as indicated by the shaded areas in the chart below: Typical Relative Humidity Range (%RH) for 55°F Cellar Temperature without Humidifier...
  • Page 20 WATER SUPPLY AND PLUMBING  Supply water pressure must be 30 to 80 PSIG,  For cases above 80 psi, install a pressure reducing valve in the water feed line to the unit.  With extremely dirty or muddy water sources, e.g., some well sources, ensure proper filtration by adding an external filter to the water line entering the unit.
  • Page 21 OPERATING INSTRUCTIONS The humidifier is controlled by the remote humidistat located in the cellar. The only function enabled on the controller is humidity. The humidistat displays temperature in addition to relative humidity; however the cooling unit temperature control is managed by the primary temperature controller. The humidistat controller will have no effect on the air handler temperature settings for the cellar.
  • Page 22 Pressing the "Up" or "Down" arrows will cause the display to change and the current set point value to blink. Use the arrows to increase or decrease the humidity set point to the desired value. The display will return to the normal display mode after a few seconds, showing the current relative humidity.
  • Page 23 GUIDELINES Region 1: Initial Cellar Startup As the temperature pulls down, the relative humidity rapidly increases from the base humidity level. This increase in humidity will happen naturally, so for a faster pull down it is strongly recommended that the humidifier not be turned on until the cellar pulls down to the set point temperature.
  • Page 24 Optional Condensate Pump The condensate pump is mounted inside the evaporator drain pan. The pump activates when the water level in the drain pan reaches a depth of 5/8”, and shuts off when the water level reaches a depth of 3/16”. The pump is provided with 25 feet of ¼”PVC drain tubing. This tubing should be routed to a suitable open drain according to the following design limits: Over time, the pump sensor may become contaminated by particles in the condensate water causing the pump to run constantly.
  • Page 25: Line Sizing Chart

    Line Sizing Chart Refer to the Line Sizing Chart below for selecting the appropriate tubing size for the length of the piping run. Note that the recommended line size may not match the connection ports on the Condensing unit and the Evaporator. Refrigeration grade fittings must be supplied by the installing technician to make the necessary transitions.
  • Page 26 Vertical Piping Guidelines Piping runs should be kept as short and compact as possible. Low-lying areas (oil “traps”) where oil can accumulate should be avoided. Refer to the following guidelines with regards to the vertical placement of the evaporator and condensing units: 1.
  • Page 27 3. When the evaporator is located above the condensing unit, pipe suction line with inverted trap as shown to prevent liquid migration to the compressor during the off cycle. The vertical lift of the liquid line is limited to 30 feet. The lift may be increased to 60 feet if an optional liquid/suction Heat Exchanger is added to the field piping.
  • Page 28 Bump Starts to protect against floodback damage, then start normally. IMPORTANT: If the system does not power up after the start up delay and Bump Start, verify field wiring according to the appropriate wiring diagram. If correct, disconnect power from the system and contact Cellarpro at 707.794.8000.
  • Page 29 o Condensing Unit Controller Startup Settings: After powering up the condensing unit, adjust the following settings on the condensing unit controller:  Hold “SET” and “Down” for 3 seconds to enter programming mode.  Use “Up” and “Down” to cycle through the parameters until “PAr” is displayed. ...
  • Page 30 The target superheat at the evaporator is 15°F +/- 3°F. 3) Reinstall the cap and cork tape insulation. 11. Confirm that the compressor, condenser fan, and evaporator fan are energized. Allow the system to balance for 30 minutes, then record all readings on the Data Sheet and submit to CellarPro for warranty activation review.
