1. Important Safety Information
DANGER
DANGER indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.
DANGER
Hazard of electric shock, explosion or arc flash
• Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices.
• This equipment must be installed and serviced by qualified HVAC personnel only.
• Comply with all local and national wiring and safety regulations applicable where unit will be installed, e.g.
National Electric Code (NEC) in the United States.
• Turn off all power supplying this equipment before working on or inside of the equipment.
• Always use a properly rated voltage sensing device to confirm power is off.
• Replace all devices, doors and covers before turning on power to this equipment.
• This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction
concerning the use of the appliance by a person responsible for their safety. Children should be supervised to
ensure that they do not play with the appliance.
Failure to observe this warning may result in death or serious injury.
WARNING
WARNING indicates a potentially hazardous situation which, if not avoided, can result in death or serious injury.
CAUTION
CAUTION indicates a potentially hazardous situation which, if not avoided, can result in minor or moderate injury.
NOTICE
NOTICE addresses practices not related to physical injury including certain environmental hazards, potential
damage or loss of data.
1.2 Handling Information
Read handling information prior to installing, operating, servicing or maintaining the equipment. Comply with local regulations

The SRCOOLDXRW12 and SRCOOLDXRW25 In-Row Air Conditioning Systems are precision, split type, DX, air-cooled systems.
They require copper piping connections to bridge the In-Row Cooler (indoor) with the condenser (outdoor). No ductwork
or raised floor is required. As a result, these are dedicated cooling systems, meaning the design enables them to operate
independently of the building’s HVAC/comfort cooling system.
The system requires charging with R-410A refrigerant.
Notes:
• These are cooling-only devices with no heating capability.
• In-Row Coolers shall be spaced properly to provide coverage across all rack enclosures. Ensure the total number and placement of all
coolers adheres to the redundancy model required as per customer design. Typical redundancy is n+1.
• Install the In-Row Cooler either on a solid surface or a raised floor. Ensure the floor is level.
• The In-Row Cooler design is for data centers and other cleanroom applications. It is not intended for harsh or dirty environments.
1. Important Safety Information
CAUTION
Hazard to equipment or personnel
• All work must be performed only by qualified personnel.
Failure to observe this warning may result in death or serious injury.
WARNING
Hazard of equipment falling over
• Use two or more persons at all times to move or turn this equipment.
• Always push, pull, or turn while facing the front and rear of this equipment. Never push pull, or turn while facing
the sides of this equipment.
• Slowly move this equipment across uneven surfaces or door thresholds.
• Lower leveling feet to floor when this equipment is at rest.
• Lower leveling feet and attach joining brackets to adjacent racks when this equipment is in final position.
Failure to observe this warning may result in serious injury or equipment damage.
CAUTION
Hazard to equipment or personnel
• Make sure no spare parts or tools are in the equipment before handling the equipment.
• Do not operate unit without the air filter. This may cause dust accumulation that can damage the unit.
Failure to observe this warning may result in serious injury or equipment damage.
CAUTION
Refrigerant high pressure and hazard to equipment
• This unit operates under high pressure. Observe proper safety precautions when operating or servicing the unit.
• The equipment is to be charged with R-410A refrigerant only.
• Copper pipe must support minimum 55 bar pressure.
Failure to observe this warning may result in serious injury or equipment damage.

2. In-Row Cooler Installation
• For maximum cooling performance in humid environments, install vapor barriers on walls and floors to ensure the cooler is generating the
highest amount of sensible vs. latent cooling.
• This product is rated for 64.0 to 98.6°F (17.7 to 37°C), 20 to 80% RH indoor temperature and 14 to 95°F (-10 to 35°C) outdoor
temperature. The system continues operating when the outdoor temperature is up to 113°F (45°C), but at reduced cooling capacity and
efficiency. The system is protected for temperatures above 113°F (45°C). Contact the manufacturer if over range.
Minimum/maximum air temperature test was conducted at 55°F (12.8°C) indoor temperature and 5°F (-15°C) outdoor temperature /
116.6°F (47°C) indoor temperature and113°F (45°C) outdoor temperature for cooling mode.
• GWP for R410A (R32/125: 50/50): 2087.5.
2.1 Unpacking
Refer to the unpacking guide attached to the outside of the In-Row Cooler container.
Note: Retain the shipping brackets attached to the In-Row Cooler if installation will be anchored to the floor.
2.2 Side Air Discharge
CAUTION: Remove front airblock (if installed flush) or install perforated side panels (if installed protruded)
before turning on the In-Row Cooler. Failure to do so will result in damage to the In-Row Cooler.
The In-Row Cooler ships with both the solid front door airblock and the solid side discharge panels pre-installed. Configure the
air discharge according the following table.
Table: Air Discharge Configurations
Front of In-Row Cooler Alignment Front Door Airblock Side Airblock Type
Flush, front-only discharge Removed Solid panels
Protruded, side-only discharge Installed Perforated panels
Protruded, front and side discharge Removed Perforated panels
Figure 2-1: Perforated side panels installed, front airblock installed. Figure 2-2: Solid side panels installed, front airblock removed.

2. In-Row Cooler Installation
2.3 Placement Clearance
Using its casters, install the In-Row Cooler beside a rack enclosure. Ensure the installation area has sufficient clearance for
both airflow and maintenance and repair. Refer to Figure 2-3: Installation Clearance Requirements below.
Figure 2-3: Installation Clearance Requirements
If installing the cooling unit at the end of a row, a minimum of 19 in. (460 mm) clearance is needed on the side for servicing.
Adjust the leveling feet to ensure the entire unit is level for proper condensate drainage.
Secure the unit directly to the adjacent rack enclosure using baying brackets. For installation next to Tripp Lite racks, use the
Z-shaped baying brackets included with the cooler. Refer to Protruded (left) and Flush (right) installation diagram below.

3. Condenser Installation (Outdoor Unit)
Note: Avoid installing the condenser in areas with excess heat, dust or debris. Refer to local codes and regulations for proper reinforcement
for high wind areas. The maximum outdoor operating temperature is 110ºF (43ºC).
3.1 Condenser Elevation and Distance
Confirm that the vertical distance between the condenser and In-Row Cooler is within the range listed in the Condenser
Elevation Installation Limits table.
Take measurements from the bottom surface (excluding legs) of the condenser to the bottom surface of the In-Row Cooler.
Table: Condenser Elevation Installation Limits
Type Vertical height value
Positive (condenser higher than indoor unit) Max: +65 ft. (20 m), bottom-to-bottom
Negative (condenser lower than indoor unit) Max: -16 ft. (-5 m)
3.2 Attach Supplied Lifting Brackets and Screws to Condenser
Figure 3-1: Attach Supplied Lifting Brackets and Screws to Condenser
Note: After removing the lifting brackets, save the screws; they will be used to attach the condenser’s legs at a later time (refer to section
3.4 Condenser Leg Installation for more information).
3.3 Lifting Crane
If the condenser will be installed on a rooftop, a lifting crane may be required.
