INSTALLATION GUIDE AND OWNER’S MANUAL
LavAdvantage™, AccuMix II™, & FlowCo™
ELECTRIC INSTANTANEOUS WATER HEATERS
Read and understand the instructions thoroughly before attempting the installation or service of the 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 fully understand the requirements before beginning this installation.
This water heater is not required by UL 499 to employ a temperature and pressure relief valve (T&P). Check with local codes to find
out if one is required. If it is, the T&P valve must be installed in the outlet hot water pipe between the heater and the isolation valve.
BEFORE ATTEMPTING ANY INSTALLATION, MODIFICATION OR SERVICE OF THE HEATER, MAKE SURE THE
ELECTRICAL POWER IS DISCONNECTED.
