SECTION V BUILT IN SAFEGUARDS
A COMPRESSOR TIME DELAY
Protects the KwiKool while in COOL mode from potential damage by delaying the compressor from
starting before the pressures in the mechanical system equalize. Always activates when the KwiKool
cycles off or is turned off, or if power is lost and then restored.
B HIGH-PRESSURE SWITCH AND ALARM
Protects the KwiKool from potential damage to the mechanical system by shutting down and alerting
operators of a condition such as stopped or slowed airflow over the condenser coil, make-up air tem-
perature above operating range, or mechanical failure. If these conditions exist, the KwiKool will sound
an audible alarm only, and display HP on the control.
To resume operation, the system requires a manual reset after corrective action is taken.
The reset switch is located on the left side of the unit as the operator faces the control in the service
door access on the compressor discharge line for KPO5 and KPO12. Push in to reset. If activated,
the operator will hear a click.
KPO25 systems have two reset switches located in the return air compartment of the system,
mounted one on each side of the compartment. If activated, the operator will hear a click.
Be sure to reset both switches if getting the HP alarm. If this alarm is engaged the system will not
operate in COOL, FAN, or HEAT mode.
C LOW PRESSURE SWITCH AND ALARM
Protects the KwiKool from potential damage to the mechanical system by shutting down and alerting
operators of the condition. This safety mode activates when pressures below 20 PSI are detected in the
mechanical system of the KwiKool. The KwiKool will sound an audible alarm and displays LP on the
control. There is an automatic reset upon correction of the low-pressure condition. If this alarm is en-
gaged the system will not operate in COOL, FAN or HEAT mode. Call 1-800-KWIKOOL, if this alarm is
present on initial startup.
D SERVICE PORTS
Located in the service access door, on the left side when facing the control panel on KPO5 and KPO12.
KPO25 service ports are in the return air compartment. This gives service personal a connection point
for service gauges to monitor the operating pressures of the KwiKool.
E SIGHT GLASS
Located in the condenser access compartment on the control side of the KPO, the sight glass allows
operators and service personal to view the condition of the refrigerant returning to the evaporator coil.
Used as a diagnostic tool by qualified personal.
