NOTES:
1. Units are suitable for use on electrical systems where voltage supplied to the unit
terminals is not below or above the listed minimum and maximum limits. Maximum
allowable phase imbalance is: voltage, 2%; amps 10%.
2. All units have single point primary power connection. The unit control circuit power
(24 v, single-phase) is supplied from the main power and does not require a separate
power source.
3. Hydronic package and cooler heaters are wired into the control circuit so they are
always operable as long as the power supply disconnect is on, even if any safety
device is open, and the unit ON/OFF switch is in the OFF position.
4. Power draw control circuits include cooler heaters (where used).
