Installation, Operation & Maintenance - HKV Series
Model Nomenclature
Notes:
1. ClimaDry
®
II reheat option (Digit 12 - D, E, F or P) must be ordered with original equipment (cannot be field added).
Unit must have DXM2 control. Not available for units with internal water valve, flow regulator options, or 575Volt.
Check unit submittal for limitations and specific requirements.
2. Antifreeze is not required for HKV but may be required due to EWT in heating or other models with orginal ClimaDry
®
Option on the same loop.
3. ClimaDry
®
II is not recommended for applications with poor water quality (see water quality guidelines in unit IOM).
The copper heat exchanger (Digit 12 - D or E) with cast iron pump are designed for closed loop systems.
4. The cupro-nickel heat exchanger (Digit 12 - F or P) also includes bronze pump, and is required for use with open loop
or ground water systems.
5. Max working water pressure for the ClimaDry
®
II
option is 145psig [999kPa].
6. Thermostat must be either:
A. Thermostat with dehumidification mode
B. Thermostat and separate humidistat or dehumidistat controller (see Page 22 for DXM2 DIP settings).
8. ClimaDry
®
II units must have minimum entering air temperature of 70°F DB / 61°F WB while in the
cooling, continuous fan, or dehumidification modes. Minimum entering air temperature while operating in the heating
mode (not continuous fan) is the minimum entering air temperature for the standard model (without the ClimaDry
®
option) in the heating mode. Operating below these minimum entering air temperatures may result in nuisance faults.
