For installation guidelines, refer to Installing the Indoor Condensing Unit on page 48.
7.6.1Piping Considerations
It is recommended that manual service
When the water source for the condenser is of poor quality, it is good practice to provide cleanable fil- ters in the supply line. These filters will trap the particles in the water supply and extend the service life of the

7.6.2Condenser Water Requirements
The standard maximum water pressure is 150 psig (1034 kPa). For applications above this pressure, consult the factory about high pressure systems.
The system will operate in conjunction with a cooling tower, city water, or drycooler.
7.6.3Regulating Valve Adjustment and Testing
Refer to 4.3.1 - Water Regulating Valve Adjustment and 4.3.3 - Testing Valve Function.
7.6.4Glycol Systems
For split system glycol systems, use drycooler and pump data found in 5.0 - Glycol/GLYCOOL- Cooled Models. See Table 16 - Drycooler data.
Electrical control interconnect to drycooler is wired from water/glycol condensing unit.
