System shall be installed, started, and commissioned by manufacturer's representative. The unit shall have the following features: 1. Dehumidification by means of a direct expansion evaporator coil. 2. Space heating by means of a packaged hot water coil. 3. Cooling mode with heat rejection to a remote outdoor air cooled fluid cooler (dry-cooler). Piping connection between dehumidifier and dry cooler, start-up, and fill with glycol shall performed by manufacturer. 4. No field refrigeration work shall be required. Substituting an outdoor condenser and increasing the refrigerant charge grows the owner's long-term liability and will not be allowed. 5. Pool water heating from reclaimed compressor waste heat by means of a full flow titanium heat exchanger. 6. Packaged minimum exhaust fan and purge fan with economizer mode. 7. Integral minimum outdoor air connection. 8. Integral purge outdoor air connection with economizer mode. 9.
