INSTALLATION GUIDE AND OWNER’S MANUAL LavAdvantage ELECTRIC INSTANTANEOUS WATER HEATERS
BEFORE ATTEMPTING ANY INSTALLATION, MODIFICATION OR SERVICE OF THIS HEATER, MAKE SURE THE ELECTRICAL POWER IS DISCONNECTED. Read and understand these instructions thoroughly before attempting the installation or service of this water heater. Failure to follow these instructions can result in serious injury, death and/or property damage. The warranty of this water heater will depend upon the proper installation according to these instructions. Some heaters come supplied with separate faucet aerators.
(CANADIAN INSTALLATIONS ONLY) CONNECT ONLY TO A CIRCUIT PROTECTED BY A CLASS A GROUND FAULT CIRCUIT INTERRUPTER. ATTENTION: BRANCHER UNIQUEMENT À UN CIRCUIT PROTÉGÉ PAR UN DISJONCTEUR DE FUITE DE TERRE DE CLASSE A. (CANADIAN INSTALLATIONS ONLY) DO NOT INSTALL IN A BATH ENCLOSURE OR SHOWER STALL OR CONNECT TO A SALT-REGENERATED WATER SOFTENER OR A WATER SUPPLY OF SALT WATER.
1) MOUNTING THE UNIT TO THE WALL THIS HEATER MUST BE INSTALLED IN A LOCATION WHERE IT IS NOT SUBJECT TO FREEZING TEMPERATURES. 1. The heater should be mounted “under the sink” as close to the point of use as possible. Ideal position is fittings pointed down, but the heater can be mounted in any orientation 2. Make sure to leave a minimum of 8 inches service 3. Remove the cover and fasten to the wall using the clearance at the end OPPOSITE the fittings.
2) PLUMBING HOOK-UP The heater is supplied with brass 3/8” compression fittings that are compatible with either stainless steel flex hose, copper or plastic pipe. Make sure these fittings are used for this installation. Contact your Eemax representative for further information. NEVER SUBSTITUTE THREADED PIPE FITTINGS USING PIPE DOPE OR TEFLON TAPE AND NEVER SOLDER ANY PIPE CONNECTIONS WHILE ATTACHED TO THIS HEATER BECAUSE DAMAGE TO THE HEATER WILL RESULT.
3. Remove the cover. Connect the pre-assembled inlet and outlet pipes to the heater and fully open the inlet and outlet ball valves. Check for water leaks. If a leak is at a compression fitting, slowly tighten the compression nut until it stops. Replace the cover. 4. Open the hot water faucet and run water for minimum 60 seconds and until the flow is continuous and free of air pockets. Close the faucet and install the aerator (if supplied).
3) ELECTRICAL HOOK-UP BEFORE BEGINNING ANY WORK ON THIS INSTALLATION, BE SURE THAT THE ELECTRICAL BREAKER IS “OFF” AND THAT ALL MOUNTING AND PLUMBING WORK HAS BEEN COMPLETED PER THESE INSTRUCTIONS. This heater must have its own independent circuit using insulated, UL listed, 2 wire cable (2 wire plus ground) of the appropriate size suitable for up to 75°C and protected by the correctly rated circuit breaker.
2. The power leads are to be secured to the L1 and L2 or L and N connectors on the terminal block or relay. The ground lead is to be secured to the GND connector on the block or the green ground wire with the provided wire nut. FAILURE TO GROUND THE SYSTEM MAY RESULT IN SERIOUS INJURY, DEATH AND/OR PROPERTY DAMAGE. 3. Leave the breaker in the “OFF” position.
3. Keep water flowing through the faucet for the next step. 4. For 60 seconds after “power ON”, display will countdown from 60 seconds to 0. When the display timer reaches 45, the unit starts heating. 5. After the 60 seconds in step 4, the display will show temperature setpoint. The heater is considered commissioned at this point. Faucet can be turned off and used as needed. Note: the temperature display will turn off after 5 minutes of inactivity.
5) UNIT OPERATION Remove screw to access user interface Using the Eemax LavAdvantage Control Functions Using the Eemax LavAdvantage is EASY. There are only 2 buttons: “–“and “+”.
