• Supply circuit protective devices may be fuses or
“HACR” type circuit breakers.
• Largest motor load is included in single circuit and
multiple circuit.
• If non-standard fuse size is specified, use the next
larger fuse size.
• J Voltage (230V) single-phase air handler is
designed to be used with single or three phase 230
volt power. In the case of connecting 3-phase
power to the air handler terminal block, bring only
two leads to the terminal block. Cap, insulate and
fully secure the third lead.
• The air handlers are shipped from the factory with
the proper indoor coil installed, and cannot be
ordered without a coil.
• The air handlers do not have an internal filter rack.
An external filter rack or other means of filtration is
required.
