V / Built in Safeguards

KwiKool is proud to provide its customers with high quality features and safety devices

that are not found in most other brands.

COOL - If the unit was previously set to the cooling mode (cool) then “cool” will be

displayed. If the compressor is running, the ”cool” on the display will be flashing. If

your unit has been sitting for over 2 minutes, this should happen immediately upon

turning the unit on, unless your set point is lower than the current room tempera-

ture. In this case your unit is ready to automatically turn on once the temperature

rises above the set point. If the unit was recently turned off or the unit turned itself

off because it reached the set point, the compressor will not turn on until the

system waits for approximately 2 minutes. This prevents the compressor from

being damaged do to a condition called short cycling. The indicator that the unit is in

the “time out” condition is that the F (or C) in the display will be flashing. When the

compressor starts, the F will stop flashing and the “COOL” will begin flashing.

Note that the condenser fan will not start immediately with the compressor. And

once the condenser fan kicks in and if the ambient temperature entering the make

up air for the condenser return is below 75 degrees F you may notice the fan

cycling on and off, this is normal. For KIB120 models, the fan will instead speedup

and slowdown in lieu of turning on and off. If the display flashes 99, this indicates

ambient temperature of 99 degrees F or more. This is normal and will stop flashing

when the ambient temperature falls below 99 degrees F.

FAN - If the unit was previously set to the fan mode then “FAN” will be displayed

and the fan will start to run.

Time Delay - Protects your KwiKool from potential damage by delaying the compres-

sor from starting before the pressures in the mechanical system equalize. This always

activates when your KwiKool cycles off, is turned off, power is lost and then restored or

the operational mode is changed. Display flashes C or F if the time delay is activated.

Condenser Fan Cycling or Condenser Fan Speed Control - Part of your

KwiKool limited freeze protection and works by regulating the discharge air flow to keep

the refrigerant pressures at the optimum range.

High-Pressure Switch and Alarm - Protects your Iceberg Series unit from

potential damage to the mechanical system by shutting down, sounding an audible alarm

and displaying a fault code (HP) when the system pressure exceeds safe operating

conditions. The high pressure switch is a manual reset switch and must be reset after

the switch is activated and the condition causing the trip is corrected.

Low Pressure Switch and Alarm - Protects your KwiKool from potential damage

to the mechanical system by shutting down the system, sounding an audible alarm and

displaying a fault code (LP) when the low side pressure is too low. This is normally

caused by low refrigerant charge. This switch is an automatic reset.

Automatic Restart - In the event of a power loss your KwiKool Iceberg resumes

operation when the power is restored. All operational functions are preserved in the

memory of the Microprocessor Board including the ON/OFF selection.
