Subsystems
Self-contained units require subsystems that are purchased
separately because of the many variations and options
available. These subsystems include the air distribution
system and the system control.
Air Distribution System
Compartment air is drawn into the self-contained unit
through a return air grill, it is cooled or warmed and blown
back into the compartment through a ducting system. The air
should be discharged high in the compartment and away
from the return air grill to ensure good circulation. Good air
distribution throughout the space is the key to comfort. An air
filter is located on the cooling unit or on the return air grill,
and must be cleaned regularly.
System Controls
SMX controls are advanced microprocessor systems that
provide a more comfortable environment and better system
protection than mechanical controls. In addition, over 20
programmable functions allow the user to customize the
system to suit the specific needs of their environment.
The SMXir System consists of the following components:
• Power/Logic (P/L) board
- Monitors and controls all
functions of the air conditioning unit.
• Keypad/Display -
A 10-button user interface with a digital
readout and LED indicators.
• Temperature-Sensing Element -
Air temperature is
monitored by a temperature-sensing element (TSEP) that
plugs into the power/logic board.
• Connecting Cable -
The keypad/display connects to the
P/L board with a CXP connecting cable.
Condensate Drain
When the air conditioner is running, moisture is removed
from the air by the evaporator coil. This condensation is then
caught in a drain pan and must be drained off. In humid
climates the system can produce a large amount of conden-
sate water that could cause significant damage if the drain
system doesn’t work properly.
Warning
The drain should have a hose attached, and should
have a trap to create a water seal to prevent hazardous
or deadly gasses from entering!
