Components

 
Item No. Description Function
1 Water valve An electrical solenoid valve energized by the float switch or the water control switch (in manual position); when open, it allows water to flow into the water pan
2 Water strainer A filter to prevent particles from plugging the water valve
3 Contactor The relay that directs power to the water heaters
4 Relay Shuts the heat off to the water pan when a low watercondition is sensed by the float switch
5 Radiant heater A long tubular heater mounted in a reflector located in the ceiling panel of the unit
6 Hi-limit thermostat A safety device mounted to the bottom of the water pan which detects an over temperature condition if the water pan runs dry
8 Water pan insert Holds the pans in place over the water
9 Pan support-top Tilts the pans used in the top toward the customer side of the unit
10 Light bulb A 60 watt rated long-life bulb that should be replaced by a bulb of the same rating
11 Lamp socket A high temperature ceramic socket for holding the light bulb

12

 Tinted glass panel

Specially tempered colored glass with a thin film of silicone that protect the light bulbs and colors the light
13 Water control switch A three-position switch on which the center position is off; in the position marked AUTOMATIC (up), water level in the unit will be controlled by the float switch; in the position marked MANUAL (down), water valve is opened directly by the switch; the MANUAL position is spring loaded so that the water valve will close when the switch is released
14 Water light A light, operated directly by the float switch, that indicates low water conditions, regardless of the position of the water control switch; the low water level is indicated when the light is illuminated
15 Thermometer Indicates the water temperature
16 Water Thermostat An electro-mechanical device used to regulate the water temperature

17

 Power Switch

A two-position, three pole switch used to turn on and off the heat and water control systems
18 Power Light Illuminates when the power switch is on and the heat and water system controls are energized; if the power light goes off during normal operation, this means the water pan hi-limit device has opened indicating that the unit is out of water
19 Radiant Heat Infinite Regulator The infinite regulator is a time proportioning controller; the higher the number set means the radiant heat will be on a greater percentage of time
20 Light Switch The light switch is a two-position, two pole switch used to turn the lights on and off
21 Light Fuse Holder The fuse holder is a protective device for the lighting circuit; the fuse is a 15 amp rating and must be replaced by a fuse of the same size and rating

22

Float Switch

An electro-mechanical sensing device used to automatically control the water level in the water pan; the sensor can be inactivated by the water control switch; the sensor illuminates the low water light when it senses a low water condition
23 Water Heater The water heater is a flat strip heater which measures approximately 3” wide by 25” long; there are two heaters rated at 1020 watts each attached to the bottom of the water pan
