Made In Rome, NY, USAWatter$aver Heat Pump Water Heater 8! !! !! !! !7. After piping has been properly connected to the waterheater, open all hot water faucets and the cold water supplyvalve to the tank and allow the tank to completely fill withwater. To purge the lines of any excess air and sediment,keep the hot water faucet open for 3 minutes after a con-stant flow of water is obtained. Close the faucet and checkall connections for leaks.WARNINGWater supply to the Watter$aver must not exceed180° F (82.2° C). Water temperatures in excess of 180°F (82.2° C) will cause the high temperature cutout switchto shut off power to the unit. The high temperature cut-out switch must be reset before the water heater canbe operated.IMPORTANT: Remember to install a suitable drainpan under the water heater and pipe the drain line toan adequate drain.WARNINGDo not operate the Watter$aver with the cold watershutoff valve closed. This can result in serious damageto the water tank and will void the warranty.ELECTRICAL CONNECTIONSCAUTIONDo not apply power to an empty or partially filled waterheater. This can result in serious damage to the tankand destroy the heating elements and will void the war-ranty.When making electrical connections, always make sure:• The electrical supply has the proper overload fuseor breaker protection.• Wire sizes and connections comply with all appli-cable codes.• Wiring is enclosed in an approved conduit (if re-quired by local codes).• The water heater and electrical supply are properlygrounded.If you lack the necessary skills required to properly installthe Watter$aver, DO NOT PROCEED. Have a qualified elec-trician perform the installation.WARNINGDo not use an extension cord to supply power to theWatter$aver Heat Pump Water Heater!!1. Install the water piping and fittings as shown in Figure 3by connecting the cold water supply to the fitting marked“C” and the hot water piping to “H.”2. The installation of unions and water shutoff valves in boththe hot and cold water supply lines is recommended foreasy removal of the unit if service or replacement is re-quired. (Figure 3.)3. ECR International recommends installing a tempering valvein the domestic hot water line of the Watter$aver. A temper-ing valve reduces the risk of scalding injuries by loweringthe point of use temperature of the hot water for faucets andshowers by mixing cold and hot water in the supply lineswhile allowing untempered hot water to be used by certainappliances such as dishwashers and washing machinesthat require increased water temperatures. By setting thethermostat on the Watter$aver to obtain the higher tem-peratures required by these appliances, you may create thepotential for a scald injury if a tempering valve is not in-stalled. (Figure 4.)4. If installing the Watter$aver in a closed water system,install a relief valve or expansion tank in the cold water lineas specified under “Closed System/Thermal Expansion.”(Figure 3.)IMPORTANT: The manufacturer recommends install-ing thermal traps to reduce the effects of stacking. (SeeFigure 3 and page 10.)5. Install a shutoff valve in the cold water inlet line. It shouldbe located close to the water heater and be easily acces-sible. Know the location of this valve and how to shut off thewater to the heater.6. Install a discharge line in the temperature and pressurerelief valve as shown in Figure 2 of these instructions.Figure 4 Tempering Valve ConnectionsCold Water InletHot Water OutletTemperedWater SupplyUntemperedWater SupplyTempering Valve** When installed in the Commonwealth of Massachusetts, the TemperingValve must have a maximum setting of 130 °FVacuum Relief Valve |
