o Separate connection for light 120v, neutral & ground.
Water connection (tap) ¼” – ½” incoming. ½” – ¾” condensate.
Condensing unit: 230-208V/60/1 or 3phase (440V/ 3-phase units also available when this is plant voltage)
Note: Amperage is in accordance to the number of diffusers and size of condensing units in system. Please
contact TMB Baking for these calculations based on model and voltage supplied by plant.
Important Notes for assembly:
Forklift is required for most deliveries

ILLUSTRATION OF DIFFUSERS AND CONNECTIONS TO THEM:
Plumbing and electrical contractors are permitted to make hole penetrations through the 31/2” walls or ceiling
panels for the purpose of mounting and running wire for light fixtures or running condensate piping from the
diffusers to the floor sinks/drains. The walls contain stainless steel or Galvalume® sheating on the inside and
outside of the panel with polystyrene and wood on the inside. There are no concealed wires or pipes inside of
the walls for a drill bit to hit. Penetrations for the refrigeration lines are pre-drilled and located in the top left side
of the diffusers
