MANUAL

“SINGLE POINT”, “FLOW CONTROLLED” and “THERMOSTATIC”

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. If supplied, the aerator must

be installed in the faucet for optimum performance. This heater must be used to heat water only and

be in a location where it is not subject to freezing temperatures. The manufacturer is not liable for any

damages resulting from improper installation or misuse.

This installation must conform to the latest requirements of the National Electrical Code and all

applicable state and local codes. This information is available through your local authorities. You must

understand these requirements before beginning this installation.

This unit is not required by UL 499 to have a Temperature and Pressure relief valve (T&P). You should

check with local codes to find out if one is required. If it is, it must be installed in the outlet hot water

pipe between the heater and the isolation valve.

IMPORTANT SAFETY INSTRUCTIONS

When using this electrical equipment, basic safety precautions should always be followed, including the

following:

READ AND FOLLOW ALL INSTRUCTIONS

A green terminal (or a wire connector marked “G”, “GR, “Ground”, or “GROUNDING”) is provided within

the control box. To reduce the risk of electric shock, connect this terminal or connector to the

grounding terminal of the electric service or supply panel with a continuous copper wire in accordance

with your local electrical code.

(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.

This heater must be installed in a location where it is not subject to freezing temperatures. 1) MOUNTING THE UNIT TO THE WALL 1) The heater should be mounted “under the sink” as close to the point of use as possible. “Single Point” will have the brass fittings on the top pointing “up”. “Flow Controlled” and “Thermostatic” will have the fittings on the bottom pointing “down”. 2) The fittings must be pointed in the vertical direction and be at least 16 inches below the level of the hot water faucet.
PAGE 4
2) PLUMBING HOOK-UP The heater is supplied with brass compression fittings that are compatible with either copper or plastic pipe. “Single Point” has 3/8” fittings. Both “Flow Controlled” and “Thermostatic” units have ½” fittings. Make sure these fittings are used for this installation. Contact your Eemax representative for further information.

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 the water a minute or two 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 degree C and protected by the correctly rated circuit breaker. Refer to the chart on page 7.

3) Leave the breaker in the “OFF” position.

4) COMMISSIONING THE HEATER BEFORE SWITCHING THE ELECTRICAL BREAKER “ON”, MAKE SURE THE INLET AND OUTLET BALL VALVES ARE FULLY OPEN AND WATER IS FLOWING THROUGH THE HOT WATER FAUCET FOR A MINUTE OR TWO UNTIL THE FLOW IS CONTINUOUS AND FREE FROM AIR POCKETS. DO NOT SWITCH THE BREAKER “ON” IF THERE IS A POSSIBILITY THE WATER IN THE HEATER IS FROZEN. 1) Make sure water is flowing through the faucet. 2) Switch “ON” the electric power supply at the breaker.
PAGE 9
5) SETTING THE TEMPERATURE At this point, the water temperature may not be very hot. Using the OUTLET BALL VALVE, slowly reduce water flow until the desired temperature is achieved. Always keep the INLET BALL VALVE fully “OPEN”. NEVER RESTRICT THE WATER FLOW USING THE INLET VALVE. The temperature is proportional to the flow through the heater; the lower the flow, the higher the temperature and vice versa.

BASIC TROUBLESHOOTING SYMPTOM: NO HEAT AND THE POWER INDICATOR LIGHT ON THE CIRCUITBOARD IS “OFF”. 1) Verify the heater is mounted to the wall correctly. “Single Point” has the brass fittings pointed “UP”. “Flow Controlled” and “Thermostatic” have the fittings pointed “DOWN”. 2) Verify it is plumbed correctly. The cold water INLET is on the “RIGHT” and the hot water OUTLET is on the “LEFT”. 3) No electrical power to the heater. Switch the breaker “ON”. 4) Incorrect power supply.

PERIODIC MAINTENANCE This heater is designed for many years of care free use. In order to maintain consistent water flow, it may be necessary to periodically clean the faucet aerator or the filter screen located in the brass inlet fitting at the heater.
