protected from corrosion with a suitable corrosion inhibitor added
periodically to the cooling water supply. It is the Customer’s responsibility
to maintain their cooling system based on analysis performed in their plant
with their test equipment. SST has no control over cooling water quality and
in particular PH and therefore cannot extend warranty protection for damage
caused by corrosion.
Chamber Exhaust
Warning! In all applications, process exhaust must be vented to the
outside atmosphere. It is the customer’s responsibility to review their
process, local laws, and facility when specifying an exhaust system
because some processes can produce poisonous or acidic gases. No valve
shall be installed in the exhaust line; the exhaust line must always vent to
free atmosphere with zero backpressure. The connection to the machine
is 3/8”-NPT, (1/2”-NPT with formic acid option).
• In installations where cooling water is available meeting the required
specifications, re-enforced polyurethane tubing with an inside diameter of
½-inch (12.7 mm) minimum is routinely used. It is not necessary to use
high temperature tubing because process exhaust is forced through a
water-cooled heat exchanger before exiting the furnace.
• In installations where the process envelope will not exceed the operating
parameters specified for operations without cooling water, Hypalon
rubber tubing, meeting ASTM D2000 CE-815, should be used instead of
re-enforced polyurethane because of its higher temperature rating.
• In all installations where N
2
/formic acid gas will be used it is highly
recommended that all connections and fittings be corrosion resistant.
Vacuum Pump Exhaust
Caution! Vacuum pump exhaust must be vented to the outside
atmosphere to prevent process-induced vapors from entering the facility.
Please review the paragraph for Chamber Exhaust and follow the same
general guidelines using ½ inch (12.7 mm) inside diameter re-enforced
polyurethane tubing, the connection to the machine is ½” NPT. Note:
Vacuum and chamber exhaust lines are to be kept separate to prevent
chamber exhaust from flowing into the vacuum pump.
Process Gas
The 1200 Table-Top soldering furnace has two separate gas inputs
identified as “GAS 1,” and “GAS 2.” Please refer to Paragraph 1.3.7 for
a listing of gases that may be used with the furnace.
DANGER! Do not use flammable gases! Forming gas mixtures may
be used with 5% hydrogen maximum.
