Congratulations! You've just purchased a new Power Pak Plus tankless water heater and will soon begin to enjoy the benefits of “going tankless.” WARNING 04 Take the time to thoroughly read and understand this safety and installation manual in its entirety before you attempt to install your new Power Pak Plus tankless water heater, as it contains important safety tipsandinstructions.
If your water heater requires a reset, be sure to TURN OFF THE BREAKER prior to resetting the unit. Resetting your unit without turning off the breaker can result in personal injury and damage to your water heater. The wire gauge necessary will vary based on amperage and distance to the breaker, but 8 gauge wire is generally sufficient for most installations. If the distance is very short, sometimes smaller gauge wire may be used.
Power Selector Minimum Breaker Position 1 and 2 20 Amperes Position 1, 2 and 3 30 Amperes Position 1, 2, 3 and 4 40 Amperes Remember that the above instructions are just guidelines that apply at most installations. POWER PAK - PLUS Amperage Control Knob Swing Check Valve PP110: Connect (1) white wire to breaker and (1) white wire to neutral. PP220: Connect both white wires to breaker. Main Water Supply Valve Green Ground Wire. Connect to ground bar on breaker box.
OFF OFF ON ON DO NOT operate the appliance if water ceases to flow during use, if the outer case or cover is loose or if the unit is not working properly. If the unit leaks or does not heat properly, disconnect the unit. ISOLATE the electrical and water supplies before removing the cover and before proceeding with installation or servicing. NEVER OPERATE THIS HEATER WITHOUT THE COVER! WATER AND PLUMBING REQUIREMENTS DO NOT USE PVC, CPVC or plastic supply lines directly to the unit.
PLUMBING 7. Use stainless steel flexible hose or copper tubing of ½" on the inlet and outlet pipes (right side water inlet, hot water outlet, left). WATER INLET RIGHT SIDE WATER OUTLET LEFT SIDE OUTLET INLET Power Selector Off Water Temperature Cold I Temperate II Hot III Hotter IIII Max. Hot Water Temperature 8. Turn on the mains water supply to the water heater and then plug the unit at the isolated electrical outlet.
We recommend that you install the unit under the sink in the main bathrooms or utility areas. This will allow for lower amperage usage and a reduced heat loss from long pipe runs. The pressure relief device is designed into the water heater. The device will work automatically, when excessive build up of pressure occurs. Do not replace the pressure relief device with any other screw. For additional savings, reduce the water flow valve at the inlet of the heater so the temperature increases.
