SINGLE POINT NO HYDRONIC PACKAGE

LEGEND

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/modules have single point primary power connection. (Each unit/module requires

its own power supply.) Main power must be supplied from a field-supplied disconnect.

3. Cooler heater is wired into the control circuit so it is always operable as long as the power

supply disconnect is on, even if any safety device is open.

4. Power draw control circuits include cooler heaters (where used).
