WASHDOWN NOTE
Testing has confirmed that with the cover in place the X 2302 Air Conditioner will successfully withstand a clean water washdown procedure
while the unit is energized. If the washdown procedure is performed with the cover removed the unit must first be de-energized, and must be
allowed to dry completely before the cover is reinstalled and power is reapplied.
SMART CONTROLLER
• All Model X 2302 X 6 Air Conditioners are equipped with a Smart Controller.
• A Remote Access Control (RAC) optional accessory is available. The RAC can be ordered along with the X 2302 X 6 , or if desired, it can be
ordered separately as an upgrade at some later date. The RAC is packaged and shipped separately from the air conditioner since it cannot
fit inside the unit. The RAC is field installable.
PRINCIPLES OF OPERATION
• If electrical power to the air conditioner is interrupted and reapplied immediately (within 3 to 5 seconds), the compressor may not restart
due to the high back pressure of the compressor. It takes a minimum of one ( 1 ) minute after shut-down for the compressor suction and
discharge pressures to equalize in order for the air conditioner to restart.
• Operating the air conditioner below the minimum ambient temperature or above the maximum ambient temperatures indicated on the
nameplate voids all warranties.
• It is recommended that the warranty section of this manual be read in order to familiarize yourself with parameters of restricted operation.
• The moisture that the enclosure air can contain is limited. If moisture flows from the drain tube continuously this can only mean that
ambient air is entering the enclosure. Be aware that frequent opening of the enclosure’s door admits humid air which the air conditioner
must then dehumidify.
Overview
The smart controller is a parametric controller for the complete management of air conditioners. All settings are pre-programmed at the
factory. Cooling/heating setpoint, cooling/heating differential and high/low temperature setpoint are designed to be adjustable by the
operator. All alarms are outputted through the alarm relay. See “AIR CONDITIONER UNIT REMOTE COMMUNICATION FEATURES” on page 18
for remote input and output capabilities.
Energizing the controller
The digital controller is wired and programmed at the factory to operate when power is applied to the air conditioner. In normal condition, the
evap fan starts operating after the completion of the self-evaluation which is less than 30 seconds and fan icon should be illuminated along
with the inlet and outlet temperature data (if an option outlet temperature sensor is installed).
Control status indication
The display has numerous symbols to indicate the various controller functions such as cooling, heating, alarming, evaporator fan, and
heating. Indicators (icons) are steady illuminated on screen when active.
