If your water heater requires a reset, be sure to TURN OFF THE BREAKERS prior to resetting the unit. Resetting your unit without muting off the breakers can result in personal injury and damage to your water heater. WARNING Hers is water contained in the coils of your water heater at all times. If your water heater is exposed to freezing temperatures, the water in the coils could freeze, causing a break in the heat exchange of the unit, or the supply and rectum lines.
The heater must be connected to its own independent electrical circuit. Install a fuse box or switch ("breaker") for exclusive use of the 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. If you aren't sure which gauge of wire should be used, contact an electrician.
Position 1 and 2 20 AMPS Position 1, 2nd 3 30 AMPS Position 1, 2, and 4 40 AMPS Remember that the above instructions are just guidelines that apply at most installations. CAUTION: these are TWO separate units. Not one unit that can be wired as 110V or 220V.
Working with electricity requires proper skills and knowledge Installation of the unit should be performed by someone who is familiar or trained in this trade. We HIGHLY recommend that you hire the services of a licensed and qualified “Electrician/Plumber” familiar with thankless water heaters installation. IMPROPER INSTALLATION CAN CAUSE INJURY OR EVEN DEATH. IMPORTANT: all electrical work and unit fixing to the wall should be completed before connecting electrical wiring.
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! DO NOT USE PVC, PVC or plastic supply line directly to the unit. A 16” copper or stainless steel pipe must be con nested to the heater. Be sure to clean the pipes before connecting the heater to the main line.
2. The unit must be mounted on a flat surface in a vertical position with the incoming and outgoing water pipes facing down. It is not possible to install the unit horizontally. Please use the installation sticker guide and screws supplied in the product's original package. Drill the wall for the indicated holes. Check that there are no hidden wires or pipes, before riling holes for wall mounting. 3. Secure the bracket to the wall with the screws supplied. 4.

The power Indicator will light. TO STOP THE WATER HEATER: Tum off the faucet.
The water temperature Is altered by Increasing or decreasing the flow rate of the water through the water heater, via the temperature control knob. Increased amperage settings will result In Increased water temperatures. Lower water outflow. Warmer water. Higher water outflow. Less hot water. NOTE: If water pressure Is low, the Inlet pipe of the water should be 3/4" with outputs of 5/8". The heater should be installed as close as possible to the point of uss to avoid heat loss.
Your Mara Power Pak Plus should give you trouble free operation, however should a problem or fault occur, the table below will assist in identifying the most common faults. Diagnosis and fault finding should be carted out by a qualified Individual, skilled In electrical/plumbing. Double check for correct wiring and that all connections ars secure. Nero that there Is sufficient water flow 10 engage unk (PS) Increase size of breaker to 40 Amps If smaller breaker Is In uss, Tum heating dial to ful.
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. The unit Is bully of fireproof material. There Is a safety thermal cut-out device In the water heater. This thermostat will cut off electricity to prevent scalding, when there is a sudden rise in water temperature, this protecting the user.
