pertinent information.
Important: Do not interrupt the flow of make-up air or the exhaust!
Use the shortest possible path with the fewest number of bends to connect to the outlet ductwork.
Measured backpressure should not exceed 0.3 inches of water column pressure for reliable ignition
and best results.
Note: Check for proper exhaust fan rotation direction before placing the equipment into ser-
vice. If the rotation is incorrect, remove power from the machine and exchange any two incom-
ing power leads.
3.3.5 Electrical Requirements
Pay attention to the nameplate of the machine - it contains the specific electrical requirements of
the machine. Additional requirements can be found in the previous section.
Note! Do not use phase adders (roto-phase) on inverter driven equipment!
The machine should be connected to an individual branch circuit not shared with lighting or other
equipment.
A lockable, load break rated, visible break disconnect switch with safe working clearances is re-
quired for all installations. A disconnect plug is also acceptable, so long as it is able to safely break
the load, is in an accessible location, and can be locked.
The connection should be shielded in a liquid tight or approved flexible conduit with proper con-
ductor of correct size installed in accordance with National Electric Code (USA) or other applicable
codes. The connection must be made by a qualified electrician using the wiring diagram provided
with the machine.
For personal safety and for proper operation, the machine must be grounded in accordance with
state and local codes and in the USA in accordance with the National Electric Code, article 250-96.
The ground connection must be to a proven earth ground, not to conduit or water pipes.
Do not connect the ground to the neutral (N) leg at the terminal strip.
If a DELTA supply system is used, the high leg should be connected to T or L3, as control power
is derived from L1 & L2.
3.3.6 Electrical Connection
Electrical connections should be made by a qualified electrician in accordance with all applicable
codes or requirements. Use a separate branch circuit to power each machine. Do not share circuits
with lighting or any other equipment.
A shielded liquid tight or approved flexible conduit with proper conductor of correct size installed
in accordance with National Electric Code (USA) or other applicable codes is required. The connec-
