Replacement Line Set - Ducane 13HPD-018-230 Instructions Manual

CAUTION
Physical contact with metal edges and corners while
applying excessive force or rapid motion can result in
personal injury. Be aware of, and use caution when
working near these areas during installation or while
servicing this equipment.
POSITIONING CONSIDERATIONS
CAUTION
In order to avoid injury, take proper precaution when lift-
ing heavy objects.
Consider the following when positioning the unit:
S
Some localities are adopting sound ordinances based
on the unit's sound level registered from the adjacent
property, not from the installation property. Install the
unit as far as possible from the property line.
S
When possible, do not install the unit directly outside
a window. Glass has a very high level of sound
transmission. For proper placement of unit in relation
to a window see the provided illustration in figure 5.
PLACING OUTDOOR UNIT ON SLAB
When installing a unit at grade level, the top of the slab
should be high enough above the grade so that water from
higher ground would not collect around the unit as
illustrated in figure 5.
Slab may be level or have a slope tolerance away from the
building of not more than two degrees, or 2 inches per 5
feet (51 mm per 1524 mm) as illustrated in figure 5.
INSTALLING OUTDOOR UNIT ON ROOF
Install the unit at a minimum of 4 inches (102 mm) above
the surface of the roof. Ensure the weight of the unit is
properly distributed over roof joists and rafters. Redwood
or steel supports are recommended. Refer to figure 5,
detail c, for rooftop wind barrier considerations.

NOTICE
Roof Damage!
This system contains both refrigerant and oil. Some
rubber roofing material may absorb oil and cause the
rubber to swell when it comes into contact with oil. The
rubber will then bubble and could cause leaks. Protect
the roof surface to avoid exposure to refrigerant and oil
during service and installation. Failure to follow this
notice could result in damage to roof surface.

Replacement Line Set

This section provides information on new installation or
replacement of existing line set. If a new or replacement
line set is not required, then proceed to Brazing
Connections on page 8.
REFRIGERANT LINE SET
Field refrigerant piping consists of liquid and suction lines
from the outdoor unit (braze connections) to the indoor unit
coil (flare or braze connections). If replacing line set, use
brazed, non−flare line set, or field−fabricated refrigerant
lines as listed in table 2.
Existing line set should meet size requirements listed in
table 2.
NOTE − When installing refrigerant lines longer than 50
feet, contact technical support for assistance. To obtain the
correct information from manufacturer, be sure to
communicate the following points:
S
Model (13HPD) and size of unit (e.g. −060).
S
Line set diameters for the unit being installed as listed
in table 2 and total length of installation.
S
Number of elbows and if there is a rise or drop of the
piping.
