Operating Limits
Environment
This equipment is designed for indoor installation only.
Sheltered locations such as attics, garages, etc., generally
will not provide sufficient protection against extremes in
temperature and/or humidity, and equipment performance,
reliability, and service may be adversely affected.
Additional Information
Units are designed to start and operate with entering
air at 40˚F (4˚C), with entering water at 70˚F (21˚C),
with both air and water at the flow rates used in the ISO
Standard 13256-1 rating test, for initial start-up in winter.
Note: This is not a normal or continuous condition. It is
assumed that such a start-up is for the purpose
of bringing the building space to occupancy tem -
perature.

Notes: 1. Maximum and minimum values may not be
combined. If one value is at maximum or
minimum, the other two conditions may not
exceed the normal condition for standard
units. Extended range unit may combine any
two maximum conditions, but not more than
two, with all other conditions being normal
conditions.
2. This is not a normal or continuous operating
condition. It is assumed that such a start-up
is for the purpose of bringing the building
space up to occupancy temperature.
Electrical Data
General
1. Be sure the available power is the same voltage
and volt operation unless specified for 230 volts.
phase as that shown on the unit serial plate. Line
and voltage wiring must be done in accordance
with local codes or the National Electrical Code,
whichever is applicable.
2. Apply correct line voltage to the unit. A disconnect
switch near the unit is required by code. Power
to the unit must be sized correctly and have dual
element (Class RK5) fuses or HACR circuit breaker
for branch circuit overcurrent protection. See the
nameplate for correct ratings.
3. All 208-230V single phase units are factory wired for
208 volt operation unless specified for 230 volts.
Operating Voltages
115/60/1 ............................104 volts min.; 127 volts max.
208-230/60/1 ....................197 volts min.; 253 volts max.
265/60/1............................238 volts min.; 292 volts max.
230/50/1............................197 volts min.; 253 volts max.
