IMPORTANT SAFETY INFORMATION. READ ALL INSTRUCTIONS BEFORE USING DANGER! WATER TEMPERATURE SAFETY SETTING Safety and energy conservation are factors to be considered when selecting the water temperature setting of water heater’s thermostat.

ABOUT YOUR HOTMAX Congratulations on the purchase of your HotMax! You have purchased the most technologically-advanced electric tankless water heater on the market today designed to produce an endless amount of near boiling hot water instantly.

1- BEFORE INSTALLATION PLEASE READ THESE INSTRUCTIONS THOROUGHLY AND COMPLETELY PRIOR TO INSTALLATION & USE. FAILURE TO FOLLOW INSTRUCTIONS COULD CAUSE PROPERTY DAMAGE, SERIOUS PERSONAL INJURY, OR DEATH. By installing this product, you acknowledge the terms of the manufacturer’s warranty. Once the heater is installed, do not return product to the place of purchase.

Alternatively, you may install an active water leak detector and shutoff valve designed to turn off your water supply in the event that a leak is ever detected. 3- MOUNTING YOUR WATER HEATER Your HotMax should be secured to the mounting surface with 4 screws (minimum 1” (25.4mm) long) using the built-in mounting holes on the back side of the heater (Figure 1). If using a pre-existing dispenser location, make sure the heater is mounted within 20” of the dispenser fittings.
PAGE 6
Notice: Before drilling any holes, manufacturer recommends dry fitting the installation to make sure the proprietary copper tube reaches both the intended dispenser location and heater.  Pre-drill three holes in the locations specified on the mounting template (Figure 2).  DO NOT completely sink all three screws. Leave ¼” clearance to hang the unit. Remove the template and hang the unit.

4- DISPENSER/PLUMBING INSTALLATION Please follow all plumbing and dispenser instructions carefully. We recommend that this product be installed by a licensed and qualified plumber in accordance with all applicable national, state, provincial, and local plumbing codes. DO NOT install HotMax with a different dispenser or outlet hot water pipe that is not included in packaging. DISPENSER INSTALLATION INSTRUCTIONS STEP 1: Identify which hole in the sink basin will be used for the new dispenser.
PAGE 8
PLUMBING INSTALLATION INSTRUCTIONS STEP 1: Thoroughly flush and check that all water lines are free of debris. Tighten the proprietary 20” 4 mm copper HOT WATER line that is connected to the dispenser to the OUTLET located on the left side of the heater when facing HotMax. Use the supplied ferrule and nut. STEP 2: Connect the COLD WATER supply line to the 3/8” INLET fitting on the right side when facing HotMax. Properly seal all compression fittings. Be careful to not overtighten.

IMPORTANT NOTES: 1. We recommend a metallic brass drain, tailpiece and p-trap as plastic (PVC) cannot withstand temperautres greater than 140 °F. 2. Do not solder any pipes with the unit connected to pipes – heat from soldering may damage the flow sensor. Doing so will void the warranty. 3. This automatic tankless water heater is equipped with both computer-controlled and electromechanical auto resetting thermostat switches for high-limited temperature protection.

5- ELECTRICAL INSTALLATION WARNING Manufacturer recommends that this product be installed by a licensed and qualified electrician in accordance with all applicable national, state, provincial, and local electrical codes. As with all electrical appliances, under no circumstances should you attempt to install, repair or disassemble this water heater without first shutting off all power to the unit directly at the fuse or breaker box. Make sure to shut off all breakers.

STEP 3: A separate 8 AWG ground (green wire) conductor for the incoming circuit is required. Route the ground wire along the same path as Line 1 and Line 2. Using a Philips head screwdriver, tighten the ground wire to the ground lead. STEP 4: Use a flat head screwdriver to DOUBLE CHECK the electrical connections to make sure they are correct and that all wire connections are tight and secure. Pull on wires to ensure that they do not pull out of their connections.

6- GENERAL OPERATING INSTRUCTIONS Operating your new tankless water heater is similar to using any traditional water heating system. However, HotMax endlessly produces near boiling hot water instantly without dropping in temperature over time so it is very important that you carefully read all of the setup procedures and operating instructions and tips to ensure the maximum performance and energy savings from your new water heater.
PAGE 13
7- MAINTENANCE To ensure maximum performance of your water heater and to reduce the risk of a water leak, we recommend the following maintenance: Remove the Eemax Steam ShieldTM steam separating aerator (Patent Pending) once a month and soak in white vinegar to descale any buildup. Perform this maintenance more often in heavy use or if the supply water is very hard (hardness > 11 GPM). FAILURE TO DO SO CAN CAUSE HAZARDOUS OPERATION – SERIOUS BODILY INJURY OR DEATH COULD OCCUR IF YOU IGNORE THIS WARNING.
