FURNACE RELIABILITY HAZARD
Failure to follow this caution may result in nuisance limit
switch cycling and unit component damage.
When a 17--1/2--in. wide upflow N coil is used with a
42060 furnace, the N coil must either be raised using a
transition piece at least 3--in. (76 mm) high or if a transition
piece is not used, the refrigerant lines must point to the front
of the furnace casing.
CAUTION
!
N Coil Installation
When a 17--1/2--in. wide upflow N coil is used with a 42060
furnace, the N coil must either be raised using a transition piece at
least 3--in. (76 mm) high or if a transition piece is not used, the
refrigerant lines of the N coil must point to the front of the furnace
casing.
Factory accessory 4--3/4--in. transitions are available.
Refer to the Product Data sheet for the current accessory transition
part number.
NOTE:
The furnace must be pitched as shown in Fig. 25 for
