The HORNE EA-1 valve must be fitted above the heating coil in the tank. It may be fitted in any orientation where the thermostat element is level with, or below, the valve body. It should NOT be fitted with the thermostat element above the valve body. A strainer should be fitted in the pipeline before each valve.
|
Where the HORNE EA-1 is being fitted to a tank which also contains an electric immersion heater, the electrical heater thermostat MUST be set at a slightly lower temperature than the control temperature for the HORNE EA-1, otherwise the HORNE EA-1 thermostat element will be overheated. |

 |
The HORNE EA-1 thermostat element must be located in a position which is always immersed in the fluid being heated. Where the element is inserted vertically in the tank, the thermostat pocket must be long enough to ensure that, at the lowest liquid level in the tank, at least 230mm of the thermostat pocket is immersed in the liquid. The HORNE EA-1 valve includes an integral thermostat pocket. It should NEVER be fitted into a separate pocket or thermowell. |
