Engineering Information  
Rheemglas® compact commercial electric water  
heaters are quality engineered models designed  
to provide the maximum amount of hot water from  
the energy input of the heating elements. These  
models include Rheem-Ruud’s System Sentinel,  
an exclusive Element Diagnositic Panel. A light  
emitting diode monitors each element’s on-off  
cycle and identifies any nonfunctioning element.  
The precision thermostat(s) is easily adjustable  
from 100°F to 180°F (38°C to 82°C), with positive  
off position at low end temperature range. With  
the design capability to be connected to 208, 240  
and 600 volt, single or three phase power installa-  
tions, they are ideally suited for a wide variety of  
water heating systems. Detailed engineering  
information is available in Tables A & B.
