|
| The unit is designed for indoor application and must be located in a space | provided on either end to facilitate tube cleaning, or removal and clear- | |
| where the surrounding temperature of equipment is between 5° C and | ance on all other sides of the unit for general unit maintenance. See the | |
| 45° C, and at no more than 90% relative humidity. Clearance must be | dimensional data tables for clearance requirements. | |

3.An expansion tank should be provided in the chilled/hot water line.
4.Thermometers and pressure gauges should be

5.During heating operation, the cooling water circuit should not be in operation and should be blown down.
6.All external piping connections are provided with JIS 10K flanges un- less noted.
7.A drain line must be installed from the smoke chamber drain to a floor drain.
8.See Figure 32 (DE), Figure 48 (NE), Figure 61 (LE) for typical sys- tem piping arrangement.
