5.5 Condensate Valve Setup
The SRCOOL33K features 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.
1
Make sure that the unit is powered down and disconnected from AC input.
2
Open side panel and locate the condensate valve (for more information, see 6.4 Installation in High-Humidity Environments in the
Installation Manual).
