When pool equipment is located below the pool surface, a leak from any component can cause large scale water loss or flooding. Pentair Water Pool and Spa, Inc. can not be responsible for such water loss or flooding which may cause damage to property or to the product.
Equipment Pad For proper drainage of condensation and rain water, place the heater on a flat slightly pitched surface, such as a concrete or fabricated slab (pad). If possible, place the pad at the same level or slightly higher than the filter system equipment pad. The equipment pad should also be in an area where leaves or other combustible debris will not collect on or around the heater.

Internal Automatic Flow Occasionally a two-speed pump will not develop enough pressure on the low speed to operate the heater. In this case, Control Valves run the pump at high speed only to operate the heater. If The inlet/outlet header of the UltraTemp ETi™ Hybrid this does not solve the problem, do not try to run the heater.
Ensure that the open end of the 90-degree elbow is oriented vertically. See Figure 11. 5. Install the Pentair pressure relief valve (P/N 072138), included in the PRV kit, or an equivalent 50 PSI 3/4” ASME-Type IV relief valve [3] into the 90-degree elbow [1].
Multi-Heater Installations All plumbing on multiple heater installations must be done in parallel (see Figure 12 and 13 below). An equal flow of water to each heater is important for optimum operation. Note: It may be necessary to adjust the water pressure switch if a unit is installed below the water level. Refer to page 10-11 for details on when and how to adjust the pressure switch.
Solar Installations Water Pressure Switch Adjustment The UltraTemp ETi™ Hybrid Heater can be used in The water pressure switch should be adjusted to turn combination with other heating schemes such as solar. All the heater off when the pump is off. Setting the switch heat sources must be plumbed in series to work correctly to close at too low of a flow can damage the appliance.

Check the setting of the water pressure switch by The use of Flexible Gas Connectors (FLEX) is NOT starting and stopping the filter pump and checking recommended unless they are properly sized according the control panel and operation of the heater between to the supplier recommendations for the heater rating.
Consult local codes and fire protection authorities about specific installation restrictions. Figure 17 The UltraTemp ETi™ Hybrid Heater is 100% factory tested, however Pentair recommends installations 18–24-in of 3/4-in be tested to ensure proper combustion and optimal Gas line from Valve performance.
Electrical Connections and Wiring RISK OF ELECTRICAL SHOCK OR ELECTROCUTION. This heater contains wiring that carries high voltage. Contact with these wires could result in death or serious injury to pool or spa users, installers, or others due to electrical shock, and may also cause damage to property. Always disconnect power circuit before connecting the heater. Label all wires prior to disconnection when servicing controls.
