2K-4. Pressure Relief Valve

A pressure relief valve is mandatory in any installation in which the water flow can be shut off between the heater outlet and the pool/spa.

A pressure relief valve is not supplied with the Hi-E2 in the United States; however, it may be required by local codes. A pressure relief valve must be provided in Canada.

To install a pressure relief valve, remove the 3/4" brass plug from the top of the inlet/outlet header (See Figure 22). Install the pressure relief valve in the opening. Provide a short length of brass or stainless steel pipe as necessary to position the valve above the sheet metal cover. Turn the valve or route discharge piping as necessary to assure that hot steam will not endanger persons near the heater. The valve setting should be at or below the maximum working pressure of any component in the filter system. The working pressure of the Hi-E2 heater is 75 psig.

2K-5. Automatic Chlorinators (Chemical Feeders)

A high concentration of chlorine (and many similar chemicals) in the pool heater can be very destructive. Heater damage caused by chemical concentration is not covered by the Teledyne Laars Warranty. See Table 7 for guidelines on pool water chemistry.
