INSTALLATION GUIDE AND OWNER’S

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. Attention: Ne pas installer dans une baignoire ou une cabine de douche et ne pas brancher à un adoucisseur d’eau régénéré avec du sel ou à un approvisionnement en eau salée.

(Canadian Installations Only) Use copper conductors only. Use bonding conductor in accordance with the Canadian Electrical Code Part I. Utilisez dez conducteurs en cuive uniquement. Utilisez des conducteurs de mize à la masse conformement au Code Canadien de L’Électricité, Partie I.

SAVE THESE INSTRUCTIONS

GENERAL

The Eemax “Single Point” or “SP”, “ Flow Controlled” or “EX” and “Thermostatic” or “EX-T” heaters will provide optimum performance and energy savings when located under the sink and as close as possible to the point of hot water use. For best performance the heater should be BELOW the point of use.

Failure to do so may void the warranty. Contact your Eemax representative for further information.

“Single Point” heaters and “Flow Controlled” heaters are to be plumbed to a cold water source ONLY and heat it with a temperature rise at flow rates as shown on the table on page 10.

“Thermostatic” heaters are the only heaters of the three outlined in this manual which have thermostatic control. “Thermostatic” heaters accept cold or preheated water and heat it to temperatures suitable for normal domestic usage up to a maximum of 140 degrees F. With the “S” option, they can be used as a temperature booster for sanitation applications sometimes required for dishwashers in commercial kitchens. Units built with the “ML” option are factory-set to a maximum temperature of 110°f and are recommended for hand washing applications. The “ML” option is an excellent choice for supplying hot water to sensor-type or metering faucets.

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. Make sure to leave a minimum of 8 inches service clearance at the end OPPOSITE the fittings.

3) Remove the cover and fasten to the wall using the four mounting holes at each corner of the back plate. Make sure the “UP” arrow on the circuit board is facing “UP”.

Replace the cover.

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.

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. DOING THIS WILL VOID THE WARRANTY.

Eemax strongly recommends that the heater be supplied directly from the main cold water line when possible. This helps to avoid a potential water flow interruption to the heater which could lead to a failure of the heating element.

For optimum performance, we recommend the use of isolation valves (full flow ball type) on the inlet and outlet pipes.

1) The heater’s cold water INLET is on the “RIGHT” and the hot water OUTLET is on the “LEFT”. Install full flow ball valves to the inlet and outlet pipes and run water through the inlet pipe into a bucket to purge it of any debris. Close the inlet ball valve.

2) Make sure the inlet filter screen is present in the inlet fitting and the inlet and outlet pipes are correctly aligned with the heater connections to minimize stress on the heater.

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). Failure to install aerator (if supplied) will result in lower-than-expected heater performance.
