OPTIONS

The following optional features may be included in your water heater. Reference included drawing specific to your heater for further details.

Low Water Cut-Off

Used as a safety device, the float type (316 stainless steel) low water cut-off is used to detect a low water situation and disengage the

operating coils in the magnetic contactor(s). Once the condition is remedied, the low water cut-off switch is automatically reset. This type of low water cut-off uses a 316 stainless steel float.

Fused Low Voltage Transformer

A fused low voltage transformer may be supplied. This option is provided only in 480-volt systems with low water cut-offs to step down the voltage to 240-volt for safety when working with control circuits. As an option, a transformer may be installed on any unit to step down the voltage to 120-volts
