Data subject to change without notice.
On the remote DryCooler,
mount the pump to its
mounting plate and mount
the assembly between the
cooler legs.
For units with brazed-
plate condensers, install a
16-20 mesh strainer in the
fluid-inlet tube nearest the
unit.
An installer trained in the
application of closed-loop
systems should perform
glycol-pipe size selection.
Improper pump and/or gly-
col pipe selection can
result in excessive noise,
inadequate solution flow or
premature pipe and pump
impeller erosion.
Glycol piping should be
installed according to stan-
dard practice. The factory-
supplied expansion tank
should be installed
upstream of the pump.
The air purger and auto-
matic float-type air vent
should be installed down-
stream of the pump -
ideally at the system high
point. If not, manual or
automatic air vents must
be installed at the high
point along with the fill fun-
nel. Air vents must also be
installed anywhere air can
be trapped in the system.
All horizontal piping runs
should be pitched upward
in the direction of flow to
prevent trapping air.
Insulate the pipes where
they run through condi-
tioned spaces if the water
temperature is likely to
drop below room-air dew
point.
Install temperature
gauges (or wells), pressure
gauges, valves, and pipe
unions according to the fac-
tory piping diagrams.
Install a fill port at the
highest point of the
system. To insure proper
glycol/water ratio, never
use automatic fillers.
Where copper tubing (use
Type L only) is used, joints
should be hard soldered.
The inlet header is con-
nected to the top of the
condensers and the outlet
header to the bottom.
FreeCool units include
head-pressure-controlled
glycol regulating valves at
the inlet connections.
Fill port at highest point.
