OVERVIEW
SAFETY PRECAUTIONS
To insure safe operation, the operator should be familiar
with the pinch points and a possible burn hazard near
the seal jaw area. Warning stickers mark the location of
these hazards.
Do not wear neckties, jewelry or loose clothing when
operating the H-1075.
Do not operate, troubleshoot or maintain the H-1075
under the influence of any drug or alcohol.
Always observe all safety warnings and notices on the
machine and in this manual.
DO NOT use flammable or toxic cleaning fluids such as
gasoline, benzene or ether.
CAUTION! Keep hands, fingers and flammable
objects out of the seal jaw area. If a foreign
object is caught between the jaws, turn main
power switch to OFF immediately to prevent
possible burns.

seal cycle.
HEAT TIMER – Controls heating time. To increase heat,
turn heat timer knob clockwise. To decrease, turn knob
counterclockwise. Timer is set in seconds – 10 seconds
maximum.
COOL TIMER – Controls amount of time that pressure
bar remains closed for cooling. To increase cool time,
turn cool timer knob clockwise. To decrease, turn knob
counterclockwise. Timer is calibrated in increments of
1/10 minute.
LED INDICATORS ON HEAT/COOL TIMERS:
• UNLIT: Timer is not active.
• SOLID COLOR: Timer is active.
• FLASHING: Timer has timed-out.

OPERATING INSTRUCTIONS
IMPORTANT! Read this section prior
to operation.
SETUP
1. Place the H-1075 on a flat working surface.
2. Locate the "Air In" port on rear.
3. Attach clean, dry air supply using 1/4" OD plastic
tubing (supplied with sealer).
4. Verify air pressure.
CAUTION! DO NOT exceed 85 psi.
START-UP
WARNING! Keep fingers away from seal jaw.
1. Insert plug into 120VAC, 60Hz outlet.
2. Turn sealer ON by pressing main power switch.
3. Set Heat Timer at #2 position (2 seconds) and Cool
Timer at #1 (6 seconds).
OPERATION
IMPORTANT! If you are vacuuming a granular or
fine substance, the machine will need a filter.
Failure to use a filter will clog the ejector and
the machine will not be able to vacuum.
1. Load the product into the bag and place the bag
opening over the nozzle (between the sealing jaws).
Pull the bag so its seal area is straight and creasefree.
2. Press Foot Switch. Jaws will close and Heat Timer LED
will illuminate.
3. Remove bag and inspect seal. If the seal is weak,
increase Heat Timer slightly. Adjust Cool Timer to
allow plastic to cool before pressure bar reopens.
7. At the end of each shift or production run, turn sealer
OFF by pressing the Main Power Switch.
NOTE: Sealing cycle may be aborted at any
time by turning Main Power Switch to "OF F."
HEATING TIPS
• Uline recommends cooling time should be double
the heating time.
• To extend element life and avoid overheating, set
Heat Timer at the lowest number for the required
seal. Slight adjustments can significantly change
results.
VACUUM TIPS
• For sealing heavy bags, heat time may need to be
increased slightly.
• Practice the above process by setting the Heat Timer
at zero and operating the machine in the vacuum
mode only. This allows the operator to become familiar
with the vacuum process without wasting bags.
• If available, attach the optional support tray. The
tray aligns the product with the nozzle, leaving the
operator’s hands free to work with the bag.
• The most desirable operator position is normally at
waist level. Otherwise, bag may be misaligned with
nozzle, affecting the evacuation flow.
• Move product as close to the nozzle as possible
without interfering with front vacuum bar. The
product’s thickness will prevent the bag from
collapsing in front of the nozzle.
• If the product is thick or bulky, reposition slightly
further from the vacuum jaw to prevent creases in
the seal area.
• As the vacuum jaw closes, gently pull the bag back
and up, away from the nozzle. Otherwise, the bag
may collapse in front of the nozzle.
4. Hold Foot Switch until desired vacuum level is
achieved. Sealing cycle will initiate when Foot
Switch is released.
5. The sealing jaws will automatically release when
heating and cooling cycles are completed. The
machine will then return to its pre-set heating and
cooling cycles.
6. Continuously monitor seal area. If the area
overheats, lower heating time and increase
cooling time.

MAINTENANCE
INSPECTIONS
At the start of each shift or production run, inspect the
seal jaw area.
1. Check the Teflon® tape covering the heating
element for wrinkles, bumps or burn marks. If present,
remove and reapply covering to smooth them out.
For burn marks, replace with new Teflon® covers.
2. Inspect the element for kinks or signs of overheating.
If present, replace with element of same length
and width.
®
3. When replacing an element, also check Teflon
cover and EPA’s insulated backing under the
element. Replacement is necessary if burns,
bubbles or other surface defects are present.
REFERENCE
Retractable Nozzle
4. Also check the Pressure Bar for burns and replace
if necessary.
CLEANING
CAUTION! Prior to cleaning, always unplug the
machine. NEVER immerse or spray the H-1075
with a hose. Failure to follow these instructions
can lead to fire, electrical shock or premature
machine failure.
Use ONLY denatured alcohol or soap and water to wipe
down your H-1075 Sealer.

Check Main Power Switch.
Check fuse.
Is the machine operating?
Has the machine’s duty cycle increased?
Is Power Switch in the ON position?
Replace fuse if necessary.
If yes, green lamp is out on the Main Power Switch. Replace
