6. Mechanical Connections
Please use following procedure when re-routing the drain line.
1
Make sure that the unit is powered down and disconnected from
AC input.
2
Open side panel and locate the condensate pump
A
, main drain
line
B
, auxiliary drain line
C
and drain line routing openings
D
E
.
3
Remove the main drain line
B
from the condensate pump valve.
Install the auxiliary drain line
C
.
4
The auxiliary drain line is pre-routed through the unit. Route the
unattached end of the auxiliary drain line to a nearby drain or
other water removal method.
Note: If a nearby drain is not available, the user must make
other water removal arrangements or relocate the SRCOOL33K/
SRXCOOL33K. Auxiliary drain line is 6 ft. in length. For drainage
at a longer distance, user must supply longer compatible drain
line. Maximum drain length is 33 ft. with a 10 ft. height.
Caution: Before moving the unit, remove any excess water from the
bottom pan. Failure to remove excess water could result in damage
to the unit and surrounding hardware.
6.2 Ducting to Outside Environment
If required, the SRCOOL33K/SRXCOOL33K can be ducted to the outside environment. Additional hardware for this application must be user
supplied; it is not included with the unit. The following requirements apply:
• Additional 250 mm (10-in.) diameter tubes may be needed
• Booster fans may be required depending upon the length of the additional tubing installed
• All four tubes must be routed to the ambient environment
• The tubes must be similar in length, with no sharp bends that could impede airflow
• All tubes must be insulated to prevent condensation on their outer surfaces
• Screens or nets must be provided to prevent insects or other solid objects from entering the tubes
• Covers must be provided to prevent rain and snow from entering the tubes
• Air temperature must be maintained between 0-40°C (32-104°F)
Caution: Unconditioned air imposes extreme load variation on the cooling equipment from summer to winter, resulting in higher system
operating costs. Equipment performance should be monitored to ensure that the venting installation is working properly. The unit’s cooling
capacity will be reduced during periods of very hot weather.
6.4 Installation in High-Humidity Environments
The SRCOOL33K/SRXCOOL33K comes with a built-in condensate removal system that evaporates condensate removed from the air by
atomizing it into the condenser air stream. During normal operation, the amount of water removed from the air is minimal; however, if the
amount of water removed from the air exceeds the capability of the internal removal system (0.85 gal/hr; 3.22 L/hr), the user must re-route
the drainage to a nearby drain using the provided auxiliary drain line.
6.3 Removing Compressor Bracket
The SRCOOL33K/SRXCOOL33K ships with a bracket to stabilize the compressor during transit. This bracket must be removed prior to
operating the unit.
1
Open rear door and locate the compressor bracket
A
.
2
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!
