IMPORTANT SAFETY INFORMATION
READ ALL INSTRUCTIONS BEFORE USING.
This system is designed to operate up to 6 tankless water heaters in a parallel manifold system. All tankless
water heaters on a single system and connected to this controller must be a like model. Do not connect water
heaters of different sizes, capacities, or types, to this system.
WARNING!
!
For your safety, the information in these instructions and the instructions provided with the water heater must be
followed to minimize the risk of fire or explosion, electric shock, or to prevent property damage, personal injury,
or loss of life.
Improper adjustment, alteration, service or maintenance can cause property damage, personal injury or death.
Only qualified service personnel should install or make adjustments.
DANGER!
!
Safety and energy conservation are factors to be
considered when selecting the water temperature setting
of a water heater. Water temperatures above 125°F
(52°C) can cause severe burns or death from scalding.
Be sure to read and follow the warning outlined in the
label pictured below.
!
D A N G E R
Water temperature over 125°
can cause severe burns

scalds.
! DANGER: Households with small children, disabled,
or elderly persons may require a 120°F (49°C) or lower
temperature setting to prevent contact with "HOT" water.
Notice: When this water heater is supplying general
purpose hot water requirements for use by individuals, a
thermostatically controlled mixing valve for reducing point
of use water temperature is recommended to reduce the
risk of scald injury. Contact a licensed plumber or the local
plumbing authority for further information.
