Location It is assumed that the design engineer has selected, sized, and located in the area to be heated. However, the information given here may be of additional help to the installer. These sketches indicate suggested basic locations for different types of unit heaters. Horizontal unit heaters should be located to give a circulatory motion, preferably in the outer perimeter of the building. The units should be spaced to properly blanket the areas with warm air.

Technical Data Technical Data: S Models The performance data listed in Table 11 includes sound ratings. The ratings provide a guide in determining the acceptable degree of loudness in particular occupancy situations. Certain general rules apply to specific selection of unit heaters with regard to degree of quietness (or loudness); • The greater the fan diameter, the higher the sound level. • The higher the motor RPM, the higher the sound level.

Maintenance Periodic Service WARNING Hazardous Voltage Open all disconnect switches and secure in that position before servicing unit. Failure to do so may result in personal injury or death from electrical shock. CAUTION Rotating Components Allow rotating fans to stop before servicing to avoid serious injury to fingers and hands. Because of the simple design of the steam and hot water unit heaters, they are nearly maintenance free.
