outdoor use� Provide protection from water and
shielding from solar radiation as necessary�
10. Max. total equivalent line length is 100 feet.
(a)
Max. elevation difference between Evap. And Cond.
Is 40 feet.
(a) (b)
(a) Contact the factory for installations with elevation
differences greater than 40 feet or total equivalent
lengths greater than 100 feet� Alternate line sizes and
specific additional refrigerant circuit components may be
required�
(b) If condensing section is 20 feet or more above the
evaporator an oil separator is to be included for each
circuit�

Add the appropriate charge of R-410a Refrigerant
using the Schrader valves to compensate for the
additional interconnecting tubing as follows:
a.
For 3/8” liquid line – add 0�6 oz� per foot
b.
For 1/2” liquid line – add 1�2 oz� per foot
c.
For 5/8” liquid line – add 1�8 oz� per foot
d.
For 7/8” liquid line – add 2�4 oz� per foot
Condensate Pump
If an optional condensate pump is to be used, it will be
mounted external to the unit�
Follow pump manufacturer instructions�
A 115 volt power supply must be field supplied for the pump.
INFORMATION
The condensate line out of the unit must be
trapped before going into the condensate
pump�
Refer to Figure 8 for the termination of the condensate tubing
inside the pump�
Refer to Figure 9 for the inverted “U” trap that is to be installed
for the condensate line�
