7.0COMPONENT OPERATION AND MAINTENANCE

7.1System Testing

7.1.1Environmental Control Functions

The performance of all control circuits can be tested by actuating each of the main functions. This is done by temporarily changing the setpoints.

Cooling

To test the cooling function, set the setpoint for a temperature of 10°F (5°C) below room temperature. A call for cooling should be seen and the equipment should begin to cool. A high temperature alarm may come On. Disregard it. Return setpoint to the desired temperature.

Heating

Reheat may be tested by setting the setpoint for 10°F (5°C) above room temperature. A call for heat- ing should be seen and the heating coils should begin to heat. Disregard the temperature alarm and return the setpoint to the desired temperature.

Humidification

To check humidification, set the humidity setpoint for an RH 10% above the room humidity reading. For infrared humidifiers, the infrared element should come On. Steam generating humidifiers should click immediately as it energizes. After a short delay, the canister will fill with water. The water will heat and steam will be produced. Return the humidity setpoint to the desired humidity.

Dehumidification

Dehumidification can be checked by setting the humidity setpoint for an RH 10% below room relative humidity. The compressor should come On. Return humidity setpoint to the desired humidity.

Electric Panel

The electric panel should be inspected for any loose electrical connections.

! WARNING

Risk of electric shock. Can cause injury or death.

The Liebert iCOM microprocessor does not isolate power from the unit, even in the “Unit Off” mode. Some internal components require and receive power even during the “Unit Off” mode of Liebert iCOM control.

The only way to ensure that there is NO voltage inside the unit is to install and open a remote disconnect switch. Refer to unit electrical schematic.

Be sure that all power has been disconnected from the unit before attempting to tighten any fittings or connections.
