5.2 System Start-Up: (Continued)
5) Engage the "CONTROL POWER" switch on the control panel. At this time the temperature controller and all optional
displays will come on.
Note: Temperature controller set point should be set to "0" at this time to prevent accidental heater
engagement during calibration procedures. Reference temperature controller section if required.
5.3 Normal Operation:
Normal operation of the TYTANu DI Water Heater will consist of the following steps:
1) Initiate water flow. Allow water to flow for several minutes to ensure all entrapped air has been removed from column(s).
2) Make sure that the “Off-On-Reset” switch is in the “Off” position.
3) Energize the unit by turning on the Electrical Disconnect.
4) Turn the “Control Power” switch to the “On” position.
5) Adjust the desired set point on the temperature controller.
6) Turn the “Off-On-Reset” switch all the way to the “Reset” position and release to the “On” position. If all safety circuit
requirements are satisfied, the heaters will operate at this point.
Note: If the temperature set point is changed, it is necessary to recalibrate the temperature controller.
5.4 Shut Down Procedure:
1) Turn “Off-On-Reset” switch to “Off”.
2) Allow heater to cool to a maximum of 95°F (35°C).
3) Turn Main Power OFF.
Note: When long shut down periods are required, drain system, and dry heater by blowing inert gas through
piping system.
Note: No scheduled maintenance is required for DI heating systems. However, it is recommended to
replace the SSR relays every 24 to 30 months as some applications may exceed the SSR relay cycle life.
Section 6: Service and Maintenance:
6.1 Maintenance:
Normal maintenance of TYTANu DI Water Heaters consists of the following:
1) Disinfect the water heater along with the rest of the plumbing system on a regular basis if continuous sanitizing such as
ozone injection is not employed.
2) Replace the temperature sensors every 24 months.
3) Replace the heater control relays and fan after approximately 24-30 months of use. Actual life expectancy varies with
application conditions such as hours of operation, control tuning parameters, applied voltage and amperage.
4) The Solid State Relay fan should be replaced and the heat sink is to be cleaned every 24 months.
