Guide Specifications

PART 1 — GENERAL

1.01SUMMARY

A.The environmental control system shall be designed specifically for precision temperature and humidity control applications. It will automatically monitor and control heating, cooling, humidifying, dehumidifying, and filtering functions for the conditioned space. The system shall be built to the highest quality engineering and manufacturing standards, and shall be floor mounted and configured for horizontal airflow, with draw-through air pattern, to provide uniform air distribution over the entire face of the coil.

1.02DESIGN REQUIREMENTS

A. The system shall be as described in the following specification as manufactured by APC.

1 . Model: ____________________________.

2 . Total net cooling capacity: _______________ kW (MBH).

3 . Sensible net cooling capacity: ____________ kW (MBH).

4 . Return air dry bulb temperature: _______________ º C (º F) DB.

5 . Return air wet bulb temperature: _______________ º C (º F) WB.

6 . Humidity: __________________________% RH.

7 . Air Volume: _______________________ L/s (CFM).

8 . Humidifier capacity: _________________ kg/hr (lbs/hr).

9 . Electrical supply: ________ V, _________ Hz.

1.03SUBMITTALS

A.Submittals shall be provided with the proposal and shall include: capacity data, electrical data, physical data, electrical connection drawing, and piping connection drawing.

1.04QUALITY ASSURANCE

A.The system shall be factory-tested prior to shipment. Testing shall include, but not be limited to: complete pressure and leak testing to ensure system integrity, “Hi-Pot” test, and controls calibration and settings. The system shall be NRTL listed, MCA, and electrical system shall be UL Listed to UL 1995 and CSA 22.2 No. 236.

1.05WARRANTY
