Low Pressure Switch And Alarm; Service Ports; Sight Glass/Moisture Indicator; Application Requirements - KwiKool KPHP Series Operation Manual

The most common reason for this alarm to activate during operation is:
Restricted water flow through the discharge tubing due to crimping or clogging
•
Too much length in the discharge line connected to the system.
•
There is an automatic reset upon correction of the condensate flow. If this alarm is engaged,
the system will not operate in COOL, FAN or HEAT mode. Call 1-800-KWIKOOL, if this
alarm is present on initial startup.
G. LOW PRESSURE SWITCH AND ALARM
Protects the KwiKool System from potential damage to the mechanical system by shutting
down the system and alerting operators of the condition. This safety mode activates when
pressures below 20 psi are detected in the mechanical system of the KPHP. The KPHP will
sound an audible alarm and display LP on the control. There is an automatic reset upon cor-
rection of the low-pressure condition. If this alarm is engaged, the system will not operate in
COOL, FAN or HEAT mode. Call 1-800-KWIKOOL, if this alarm is present on initial startup.
H. SERVICE PORTS
Located in the filter access compartment in the front of your KPHP below the control panel.
This gives service personnel a connection point for service gauges to monitor the operating
pressures of your KPHP refrigeration system.
I. SIGHT GLASS/MOISTURE INDICATOR
Located in the Discharge Air / Make-up Air inlet. This feature allows operators and service
personnel to view the condition of the refrigerant returning to the evaporator coil. Used as a
diagnostic tool by qualified personnel.
SECTION VI - APPLICATION REQUIREMENTS
A. AIR TEMPERATURE REQUIREMENTS - COOL MODE
The environmental requirements of your KPHP unit at the installation site are 60 to 110 F for
the Condenser Make-up Air located on the front inlet on the top of the unit. If the unit is oper-
ated in an environment above 110 F the HP Reset switch may trip, stopping the unit's com-
pressor.
Temperatures below 60 F will cause the Discharge
Air exhaust fan to cycle excessively and may dam-
age the fan cycling switch, which requires qualified
service personnel to repair. Failure to use qualified
service personnel can void your warranty.
