Mechanical Connections; Duct Installation - Tripp-Lite SRCOOL33K Manuel D'installation

5. Stabilization and Baying
5.2 Baying
If your application requires the SRCOOL33K to be bayed in a row of rack enclosures:
• Locate the two baying brackets that correspond to baying connection points on the adjoining racks. If necessary, remove screws from the
baying connection points of the adjoining racks.
• Loosen the screw in each baying bracket and turn each bracket 90 degrees, aligning each bracket with the corresponding baying
connection point on the adjoining rack.
• Connect each bracket to the adjoining rack using the screws removed in Step 2, but do not fully tighten the screws. Adjust the position of
the unit as required and tighten all screws.

6. Mechanical Connections

If the condenser airspace is a drop ceiling plenum and is connected to a building cooling system return, the unit should be installed using
the flexible air ducts ducted through the ceiling tiles. This is the preferred method for managing condenser air. For proper operation, the
plenum must provide adequate airflow volume within the allowable temperature range, and be capable of continuously treating heat rejected
by the unit. This requires:
• At least 1012 CFM (1720 m
• Condenser inlet air temperatures between 32°F-104°F (0°C-40°C)
• Total heat rejected by condenser will be up to 55,000 BTU (16kW) per unit. The condenser air must be treated by the building cooling
system or exchanged with outdoor air.
If the building cooling system has night and weekend setbacks, is shut down during the off-season, shut down for maintenance, or has
limited excess capacity, an alternative to the standard installation may be required.
Caution: A very large plenum is not a substitute for proper ventilation and heat rejection. Heat rejected into the plenum must be
able to exit the facility. Otherwise, heat buildup in the plenum will cause the unit to shut down.
6.1 Removing Compressor Bracket
The SRCOOL33K ships with a bracket to stabilize the compressor during transit. This bracket must be removed prior to operating the unit.
Open front door and locate the compressor bracket

Remove both screws and lift bracket out of the unit.

Caution: Do not loosen or remove the bolts attaching
the compressor to the bottom of the unit.
Warning! Failure to remove the compressor bracket
voids the product warranty!

6.2 Duct Installation

If installing in an application without air ducts, proceed
to 6.4 Ductless Installation.
Remove the six screws securing the top panel and remove the panel
from the unit.
Install two exhaust flex duct tubes to the front and two supply flex
duct tubes to the back of the unit. All four tubes must be ducted out
of the conditioned room.
Take installation requirements into consideration when deciding
where to run the flexible ducts. Ensure that the four duct tubes are
similar in length, with no sharp bends.
To prevent hot air from bypassing the airflow between the exhaust
and supply air duct, ensure that the two exhaust tubes (front)
protrude higher above the ceiling tile than the intake tubes by a
minimum of 6 inches. In installations with ducts less than 24 inches
high, the supply ducts should be turned 90° and pointed towards the
supply of fresh air. The exhaust ducts should be turned 90° and face
towards the building HVAC return.
Note: It may be necessary to secure the flex duct tubes above the ceiling.
Caution: Use only the provided ducts when making condenser ventilation connections. Any additional length of ducting may significantly
degrade the performance of the unit.
