COMPONENTS OPERATION GUIDE AND MAINTENANCE 

 

 

HIGH-SPEED MOVING PARTS 

Risk of high-speed moving parts can cause injury or death. Disconnect all local and remote electric 
power supplies and make sure blowers have stopped rotating before performing service operations. 

Do not operate up-flow units without installing a supply air plenum, ductwork or protective guard 
over the blower openings.  

The unit you have received is very special.  It is specifically designed for Computer Room 
applications.  Please read the following INSTRUCTIONS prior to working on the equipment.  
 

ELECTRICAL DATA:

 208v, 3 phase, 60 h, 460v, 3 phase, 60 hz, 208v, 1 phase, 60 hz, 575v, 3 phase, 60 

hz, 3 phase, 60 hz, or 415/380v, 3 phase, 50 hz. 
Please check the voltage.   

 

NAMEPLATE DATA:

 Refer to the unit name plate.  It indicates all the electrical data for the unit.  

LOCAL ELECTRICAL CODES OR ANY OTHER APPLICABLE CODES MUST BE COMPLIED WITH PRIOR TO 
WORKING IN THE UNIT.

   

 

9.1

 

System Testing 

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

9.1.1

 

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

9.1.2

 

Heating 

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

9.1.3

 

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.
