Page 5: Safety Information
This installation and operation manual (IOM) contains important safety information that should be followed during installation or servicing of a System 2100 series. Below is general safety information as well as descriptions of safety and accident prevention symbols that will be utilized throughout this document. - Page 6 DESCRIPTION OF IMPORTANT ACCIDENT PREVENTION SAFETY SYMBOLS SYMBOL DEFINITION Indicates an extremely hazardous situation which, if not avoided, will result in death or serious injury. Use of this symbol is limited to the most extreme situations Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
- Page 7 System 2100 Series equipment requires a permanent power connection from an isolated circuit breaker. The customer must provide earth ground to the unit per NEC, CEC, and local codes when applicable.
- Page 8 While every precaution has been made to ensure sharp edges, splinters, and exposed fasteners have been minimized internally and externally on the unit to prevent personal injury, it is highly recommended that all personnel installing or servicing the unit wear safety headgear, glasses, gloves, and shoes at all times.
- Page 9 severe property damage and loss of critical data center equipment. Suitable leak detection system should be installed inside or around the proximity of the unit to minimize any type of property damage. REFRIGERANT LEAKAGE DUE TO FREEZING TEMPERATURES AND/OR CORROSION Refrigerant leaking from the unit coil or piping due to freezing and/or corrosion can cause serious equipment and building damage.

Page 14: Important - Read Before Installing
5.2 IMPORTANT – READ BEFORE INSTALLING Check the power supply. Voltage, frequency and phase must correspond to that specified on the unit nameplate. The power supply must be able to handle the additional load imposed by this equipment. 6 LOCATING THE UNIT Consult local building codes and National Code for special installation requirements. -
Page 15: Setting Of The Unit
Install unit on leveled solid floor that can support the unit weight and vibrations. Securely mount the unit with floor and brace it with wall if needed. Install the unit closer to the largest heat load. Air distribution is very important for proper unit operation. Air balancing is required to obtain design CFM at site. -
Page 16: Connections
6.2 Connections In connecting the unit, several items must be addressed. They are: 6.2.1 Structural Support The unit can be installed directly on the floor of on the raised floor without the need for any special support. The floor should be level. Gasket material should be placed between the bottom perimeter of the unit and the floor on the downflow unit to act as vibration isolator. -
Page 17: Water Connection
6.2.4 Water Connection Follow local and building codes for field piping installation. A close circuit dry fluid cooler is to be used. A pump package for field install by other is generally included in the system with separate cabinet unit. Provide a shut off valve in supply and return line for isolation. Refer to general unit dimension for location of piping connection access. -

Page 19: Electrical Connection
Note: Glycol and water cooled units are designed for maximum of 150 psig water pressure. Higher pressure units are available; refer to unit nameplate. 6.2.5 Electrical Connection The unit is completely factory wired with self-contained controls. IMPORTANT - Before proceeding with the electrical connections, make certain that the volts, hertz and phase correspond to that specified on the unit rating plate. -

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. -
Page 25: Dehumidification
9.1.4 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. 9.1.5 Electric Panel The electric panel should be inspected for any loose electrical connections 9.2 Steam Humidifier The steam humidifier on System 2100 system is the most advanced OEM steam humidifier and provides steady and reliable humidification using the same proven cylinder technology as Nortec’s... -

Similar to the clogged filter switch, adjustment may be necessary for the no air flow switch(s). The loss of airflow switch is wired in the normally closed position to open on airflow and the dirty filter switch is wired to the normally open position and set to close with dirty filter. Adjustment can be made by removing the top cover and turning the dial to the proper pressure. - Page 36 (1) Check electrical components and tighten any loose connections. (2) Check all wiring and electrical insulators. (3) Check contactors to ensure proper operation and contact point for wear. (4) Check that fan motors (if applicable) are operational, ensure fan blades are tight and all mounting bolts are tight.
