1. Introduction

Tripp Lite's SRCOOL33K/SRXCOOL33K is a self-contained air conditioning unit housed in a standard 42U enclosure. The SRCOOL33K/SRXCOOL33K is optimized for general computer room cooling or supplemental cooling in a large server room. It features an inverter-driven DC (direct current) variable-speed compressor that delivers high-efficiency precision cooling. This helps maintain set temperature without the traditional method of wasteful On/Off cycling.

A menu-driven, multi-line LCD screen provides on-site monitoring and control of various operating conditions. These operational conditions can also be monitored and controlled remotely via SNMP, Web, telnet or Modbus.

2. Important Safety Instructions

SAVE THESE INSTRUCTIONS

All sections of this owner's manual contain instructions and warnings that must be followed during the operation of the products described in this manual. Read ALL instructions before attempting to operate these products. Failure to comply may invalidate the warranty and cause serious property damage and/or personal injury.

• Prior to use, the individual user must determine whether this device is suitable, adequate or safe for the use intended. Since individual applications are subject to great variation, the manufacturer makes no representation or warranty as to the suitability or fitness of this device for any specific application.
• The cooling unit operates under pressure. Observe proper safety precautions when operating or servicing the unit.
• Do not operate the unit with any cover, guard, door, or panel removed unless the instructions indicate otherwise.
• Do not run cabling or service utilities in front of the fan outlets.
• Connect the unit directly to a grounded AC power outlet. Failure to do so may cause electric shock or fire. Note: If the unit is hardwired, the user should ground it according to local regulations.
• The power supply for the unit must be rated as specified on the unit's nameplate.
• Never modify the unit's plug or use an adapter if the unit is equipped with an input power cord.
• Comply with all local and national wiring and safety regulations applicable where the unit will be installed, e.g. The National Electric Code (NEC) in the United States.
• On models with an input cord, never use the cord as a means to turn the unit on or off. A serious electric shock may occur. Always use the control panel to power the unit on or off.
• Always turn the unit off and disconnect it from the mains input source by unplugging the unit or opening the mains circuit breaker before performing maintenance.
  • Before connecting the unit to a dedicated drainage system, turn it off and unplug it.
• Maintenance should be performed by trained personnel only.
• Do not use thinners, alcohol, detergents or abrasive brushes to clean the unit's cabinet. These may damage the cabinet.
• Do not operate the unit without the air filter. This may cause dust accumulation that can damage the unit.
• Do not attempt to operate the unit in any room with inadequate air circulation. There must be adequate airflow to the condenser.
• Do not place objects on top of the unit.
  • Prior to operation, ensure that:

- The unit has been properly installed in accordance with the procedures detailed in the Installation Manual

• There is no evidence of damage to the unit

• The unit is level and stabilized

- The clearance around the cooling unit complies with local and national codes and regulations as well as the installation manual

- Warning! Do not use this equipment in the presence of a flammable anesthetic mixture with air, oxygen or nitrous oxide.

3. Features

Line drawing of a multi-tiered industrial air conditioning unit with mounting holes and control panels (no text or symbols)

• 33,000 BTU of cooling power
- Variable-speed, DC-inverter-driven compressor and microprocessor-controlled electronic expansion valve (EEV) enable precision cooling adjustments
- Soft-start feature limits inrush current to prevent introduction of line noise, voltage disruptions and potential circuit overloads
- Self-contained, zero-maintenance unit atomizes condensate and expels it through the exhaust air stream—no floor drain, water collection tank, external condenser, refrigerant piping, ductwork or plumbing required when used in typical conditions
- Convenient LCD control panel and network interface enable local and remote monitoring and control of temperature, fan speed, alarms and logging via front-panel buttons, SNMP, Web, telnet or Modbus
- Row-based airflow path maximizes hot-aisle/cold-aisle efficiency and cooling predictability by supplying cold intake air high in the cold aisle and removing hot equipment exhaust air low from the hot aisle
• Eco-friendly R410a refrigerant meets environmental standards worldwide
• Nominal 208-240V AC Input, 50/60 Hz frequency compatibility

Regulatory Notice: This unit carries less than 22 lbs. of refrigerant and complies with all Department of Transportation shipping regulations. It is exempt from any additional requirements. The user does not have to make any extra accommodations to transport the unit.

5. Operation

Caution: Before attempting to operate the SRCOOL33K/SRXCOOL33K, ensure that it has been properly installed in accordance with the Installation Manual, including stabilization and sufficient clearance around the unit.

Tip Warning! If the unit has been tilted more than 15^ during shipping, unpacking or installation, allow unit to stand for 24 hours before turning on. Do not operate if there is visible internal or external damage.

5.1 Cooling Methods

The main function of the SRCOOL33K/SRXCOOL33K is to remove waste heat and return treated air to the room at the required temperature. The specific cooling method used is determined by the configuration of the rack enclosures in the room. The unit continuously varies the cooling output to maintain a set temperature at the return of the unit. The cooling output is varied by constantly adjusting the speed of the fans and the compressor. If desired, the fan speed may be set to a constant value by the user. Note: Setting a lower fan speed may limit the unit's capacity.

The unit uses the setpoint entered by the user to control the fan speed. This variable should be set based on the installation configuration.

Configurations

Room Cooling Mode: When the unit is installed stand-alone in a server room acting as a CRAC unit, the setpoint should be set to the desired room temperature.

In-Row/Hotspot Mode: When the unit is installed in a hot aisle/cold aisle configuration, the setpoint should be set to the desired cold aisle temperature plus the expected temperature rise across the problem rack ( 10^ ; 50^ ).
