drops below 38°F or water flow has ceased
the 24VAC control circuit will be broken to
disable the cooling system.
Electrical
Verify the unit name plate agrees with
power supply. M2 Series units are provided
with single point power wiring connections.
Connection terminations are made to the
main terminal block. A complete set of unit
specific wiring diagrams, showing factory
and field wiring are laminated in plastic and
located inside the controls compartment
door.
All units require a field supplied electrical
overcurrent and short circuit protection.
Device must not be sized larger than the
Maximum Overcurrent Protection (MOP)
shown on the unit nameplate.
Codes may require a disconnect switch be
within sight of the unit.
Note: Do not install the required field
installed overcurrent protection or
disconnect switch on the unit!
Electrical supply can enter through the
bottom or side of the controls compartment.
Entry must be field cut into panels of the
unit.
Disconnect all electrical power
sources before servicing the unit.
More than one power source may be
provided. Failure to do so may result
in injury or death from electrical
shock or entanglement in moving
parts.
