Horizontal unit installation
clearance
Adequate clearance should be spared
for service access. Required service
access for horizontal unit is shown in
Figure 3. A 457mm pass-way space
should be reserved around the unit
for service. For units with supply and
return at the same side, as shown in
Figure 3, a 76mm pass-way at one
side of the unit, other methods should
be taken for thermal expansion valve
maintenance. This configuration
is typical for units installed in a
constrained place, corridor specially.
