Premium Heavy Duty Electric Water Heater

Optional Equipment & Construction

■Silicon Bronze Tank – Available for deionized water.

■Stainless Steel Tank – Available for deionized water.

■150 or 160 PSI Working Pressure – Available when required. Must be specified at time of order.

■Handhole Cleanout – 4˝ x 6˝ size.

■Combination Temperature/Pressure Gauge – Dial type combination gauge (shipped loose).

Control Options:

■Low Water Cutoff – Probe type electric low water cutoff prevents energizing of elements in the event of low water condition.

■Override Switches – A simple form of load control allows all or part of unit input to be controlled manually. Up to one override switch per contactor is available.

■Indicating/Pilot Lights – For indicating element operation and/or switch closure. Up to one indicating light available for each switch and/or contactor is available.

■Thermostat Step – The simplest form of modulation. Allows elements to be stepped on in groups or individually by specifying additional thermostats (up to 1 per contactor).

Control Options Continued:

■Sequencer – Two or three step time delay sequencer provides for stepping of elements in groups or individually (maximum of 1 step per contactor).

■Modulating Step – Solid state electronic control device that modulates input to match load through progressive sequencing of steps (up to 3 steps with maximum of 1 per contactor).

■Time Clock – Seven day clock may be programmed for up to 14 on/off operations per week. Skip a day feature allows for weekend shutdown.

■Immersion Auto Reset High Limit – Adjustable automatic reset type. Provides additional protection against high temperature conditions.

■Safety Door Interlock – Prevents openings of control panel door when heater power supply is energized.

NOTE: Once door is open, the heater may be energized if necessary for service diagnosis.

■Pressure Limit Switches – Both high and low pressure limit switches available.

■Power Circuit Fusing – Sub-divides internal circuitry with maximum of 60 amp fuses. Supplied as standard when required by NEC and UL.

■Alarm Horn – Horns may be furnished to warn of any condition in the heater for which sensors have been specified.

*Figured at 1 KW (3413 Btu) = 4.1 gallons at 100˚F temperature rise. **Available on 50 gallon models or larger.

To determine recovery rate per minute, divide recovery rate per hour by 60. NSF ratings may be obtained by multiplying above figures by 0.98.
