ELECTRIC INSTANTANEOUS WATER HEATERS
BEFORE ATTEMPTING ANY INSTALLATION, MODIFICATION OR SERVICE OF THIS
HEATER, MAKE SURE THE ELECTRICAL POWER IS DISCONNECTED.
Read and understand the instructions thoroughly before attempting the installation or service of this water heater. Failure to follow the instructions can result in serious injury, death and/or property damage. The warranty of the water heater will depend upon proper installation according to the instructions. Some heaters come supplied with separate faucet aerators. If supplied, the aerator must be installed in the faucet for optimum performance. The heater must only be used to heat water and must be installed 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.
The installation must conform to the latest requirements of the National Electrical Code and all applicable state and local codes. This information is available through local authorities. You must understand the requirements before beginning this installation.
This unit is not required by UL 499 to employ 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

SAVE THESE INSTRUCTIONS
GENERAL
The Eemax, Inc.™ FlowCo is a non-thermostatic electric tankless water heater. FlowCo is specifically designed to take in cold water and heat it to temperatures suitable for handwashing and other fixed-flow applications.
To obtain optimum performance and energy savings, the unit should be located as close as possible to the point- of-use. The unit is supplied with compression rings and nuts suitable for direct coupling to 3/8” copper or PEX™ piping. Do not use additional screwed fittings, pipe dope or teflon tape – doing so will void the warranty. DO NOT SOLDER PIPES WHILE THE UNIT IS INSTALLED as serious damage to the heater will result and the warranty will be voided.

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 on the wall 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 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. Replace the cover.

2) PLUMBING HOOK-UP
The heater is supplied with 3/8” brass compression fittings that are compatible with either copper or plastic pipes. 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 trunk 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.
System Requirements:
•Minimum/maximum working pressure: 30 PSI/150 PSI
•Optimal operating pressure range: 35 to 80 PSI
•Minimum turn on flow rate is model dependent (refer to the table below)
