Never place the chiller in a location where excessive heat, moisture,
inadequate ventilation, or corrosive materials are present.

Note Refer to the nameplate information on the rear of the chiller.

Air-cooled chillers retain their full rated capacity at 20°C setpoint in ambient
temperatures up to 25°C (77°F). For ambient temperatures above 25°C please
de-rate the cooling capacity 3% for every 1°C above 25°C (77°F), up to a
maximum ambient temperature of 40°C (104°F). Note that when operating
at a process temperature lower than 20°C the de-rate percentage may increase
due to additional gains from losses to ambient.
Note Depending on the setpoint and ambient temperatures, there may be a
heat gain or loss through the plumbing resulting in a variation from setpoint
temperature at the application inlet. Applications with large temperature
variations between ambient and setpoint temperatures, and/or long plumbing
lengths, may require additional insulation.

ThermoFlex2500 air-cooled chillers have a two-speed fan. Should the chiller's
internal ambient temperature reach 50°C for 30 seconds, or reach 53°C, the
fan speed will switch from slow speed to high speed to maintain internal
temperatures within acceptable limits. When the temperature reaches 44°C or
below for at least 15 minutes the speed will return to low. When in high speed
the chiller's decibel level increases significantly.
Note
High speed is required for the chiller to achieve its 2500 watt cooling
capacity. At high-end operating conditions the fan can be set to run at high
speed all the time using the controller's Setup Loop, see Section 4.

Site Requirements
*Because of the decrease in air density, maximum temperature for the air entering an air-cooled
ThermoFlex is reduced by 1°C per 1,000 feet above sea level. In addition, cooling capacity is
reduced 1.2% per 1,000 feet above sea level.
