� CAUTION! �

Water Source Heat Pump systems (including Water Loop Heat Pump systems) must have antifreeze protec- tion to 20°F [-6.7°C] for ClimaDry applications. The ClimaDry option MUST NOT be used on open water loop systems, or any system without antifreeze protection.

Notes:

1.ClimaDry reheat option must be ordered with original equipment (cannot be field added). Unit must have DXM control. Not available for units with internal water valve, or flow regulator options. Check unit product catalog for limitations and specific requirements.

2.ClimaDry cannot be used on open loop systems, only closed loop systems.

3.ClimaDry systems must use appropriate antifreeze solutions.

4.ClimaDry is not recommended for applications with poor water quality (see water quality guidelines in unit IOM). The copper heat exchanger with cast iron pump (standard ClimaDry option) are designed for closed loop sys- tems.

5.Max working water pressure for the ClimaDry option is 145psig.

6.Available with TT, TS models. Check unit product catalog data nomenclature for models with ClimaDry reheat option.

7.Thermostat must be either:

1.Thermostat with dehumidification mode (similar to ATA32U02)

2.Thermostat and separate humidistat or dehumidistat controller (see Table 3 for DXM DIP settings).

8.ClimaDry units must have minimum entering air temperature of 70°F DB / 61°F WB
