must be approved by the factory before installa-
tion. Design information to be submitted for approval
includes:
1.
Location of aftercooler module – inside or out-
doors.
2.
Range of operating ambient temperatures at the
aftercooler location.
3.
Pipe type and size(s) to be used to connect the af-
tercooler, separator, and compressor unit – mini-
mum pipe size is 3” NPT.
4.
Lengths of the pipe run. If more than one pipe size
is used, list length of each size and total length.
5.
Number and size of elbows, tees, unions, reduc-
ers, and valves to be used in the pipe run.
6.
A dimensional sketch of the proposed piping sys-
tem showing location of the compressor unit, af-
tercooler, separator and auxiliary air receiver, pipe
and fittings of 3 through 5 above.
Water–Cooled Machines (Figure 2–4) – On water–
cooled machines with aftercooler, the moisture separa-
tor and condensate drain are shipped loose and must
be installed by the customer. The customer must fur-
nish and install all water piping required.
INSTALLATION FOR COLD WEATHER OPERA-
TION – It is recommended that whenever possible the
unit be installed inside a shelter that will be heated to
temperatures above freezing (32
_
F, 0
_
C). This will
eliminate many of the problems associated with operat-
ing the units outside in cold climates where freezing
rain, drifting snow, freezing condensate, and bitter cold
temperatures are encountered.
Refer to Engineering Data Sheet 13–9–411 for the ad-
vantages of using the heat recovered from rotary com-
pressors. This heat recovery could easily pay for an
adequate shelter for the unit.
When an outside installation must be made, the pre-
cautions required will depend on how severe the envi-
ronment will get. Following are general guidelines for
outside installations:
Cold Weather (Down To +10
_
F)
1.
Be sure all control lines, drains, and traps are
heated to avoid freezing of condensate. A heat
tape with thermostat control is generally satisfac-
tory for this purpose and can be obtained at vari-
ous local plumbing or hardware outlets.
2.
If an air–cooled aftercooler is to be used, provi-
sions to bypass the aftercooler should be made.
Since cold air contains very little moisture, suc-
cessful operation can be achieved without the af-
tercooler. Successful operation down to +15
_
F
can be accomplished by reversing fan flow, but
cooler bypass should still be provided should it be
required.
3.
Provide at least some simple shelter such as a ply-
wood windbreak to protect against drifting snow.
4.
Use only Gardner Denver AEON 9000 SP Lubri-
cating Coolant.
