Data subject to change without notice.
IMPORTANT:
Cut tubes as necessary using a tube-
cutter only. DO NOT use a saw.
Never apply heat to a refrigerant line
until all pressure has been released -
unsafe pressures could result, causing
violent explosion and serious personal
injury or death. Be sure the area is
well ventilated.
Air-cooled systems must be installed
by qualified refrigeration technicians,
using industry-standard practices.
Dectron, Inc. assumes no
responsibility for improper installa-
tions or for the results of failure to
follow instructions in this manual.
IMPORTANT:
The total length of tube one way
must not be greater than 100 ft.
(30 m). The total equivalent length
must not be greater than 150 ft.
(45 m). The remote condenser
must not be located below the
Ecosaire® unit.
IMPORTANT:
Never allow dirt or other foreign
materials to enter the remote con-
denser or the tubes connecting it
to the Ecosaire® unit. Foreign
material may damage valves and
other components.
If the inside of the tubes is con-
taminated with dirt, oil, sludge,
rust, or other materials, then they
must be thoroughly cleaned.
IMPORTANT:
Never allow liquid water to enter
the remote condenser or the tubes
connecting it. Water must be
removed from the remote con-
denser and the tubes that connect
it to the
Ecosaire® . Evacuation
will take much longer if liquid water
is present.
