Connect the device to an outlet with a protective conductor. Any interruption of the protective con-
ductor inside or outside of the device is dangerous.
Only use extension cables with protective conductors.
The local supply voltage must match the nominal voltage specified on the device. Maximum network
impedance according to EN 61000-3-11 / UL 499 / CSA C22.2 No 88: Zmax = 0.141 Ω + j 0.088 Ω.
In case of doubt, the responsible electricity supply company should be contacted.
If the line voltage fails, then the main switch and the drive must be switched o (extend hot-air blower).
Danger to life
Before opening the device, pull the power plug out of the socket, because voltage-bearing components
and connections will be exposed when it is opened.
Danger of fire and explosion
Risk of fire and explosion caused by improper use of the automatic welding machine (such as material
overheating), and particularly in the vicinity of flammable materials and explosive gases.
Risk of burning
Do not touch the heating element tube and nozzle when they are hot. The device should always first be
allowed to cool down.
Never point the hot air flow at people or animals.
Caution
Warning
Read through the operating instructions before commissioning for the first time.
In addition to the safety instructions contained in the individual sections of this instruction manual, the following
regulations must always be observed.
1. Important safety instructions

Anti-fall protection when working on areas where there is a danger of falling.
When welding on roof parapets (parapet, eaves), the hot air welder on the carrying handle (5)
must be secured to a stop fixture with horizontal guides (such as rail or rope safety systems)
as protection against falling.
With respect to the safety chain, care must be taken to ensure that all of the safety elements (carabiner
hooks, ropes) have a minimum load-carrying capacity of 7 kN in every direction that can be anticipa-
ted. For the suspension of the machine, it is mandatory to use clasp carabiners (Twist-Lock or screw
types). All safety chain connections must be installed and checked in accordance with manufacturer
specifications.
Health risk
Welding PVC materials creates harmful hydrogen chloride vapors. The hot air welder should be used
only in well-ventilated indoor areas.
Read the material safety data sheet from the manufacturer of the material and follow that company's
instructions. Be careful not to burn the material during the welding process.
Danger of fire and explosion
Never use the hot-air welder in explosive or readily inflammable surroundings. Maintain sucient
distance from combustible materials or explosive gases at all times.
Caution
The device should only be used on a horizontal (roof slope up to 30°) and fireproof support.
Caution
Comply with national statutory requirements regarding occupational safety (securing personnel or
devices).
6.1 Work environment and safety
6. Commissioning your UNIROOF 700/300

17
Caution
The eects of gravity mean a danger of uncontrolled falling or sinking. The securing point is not desig-
ned to withstand the shock-like stress of an abrupt fall.
Absolutely contact the manufacturer if anything is unclear during installation or operation.
Caution
Only secure the hot air welding machine by the carrying handle (5).
Caution
The hot wedge welding machine must never be fastened to single anchoring points which allow ropes
to sag. The connection equipment must always be set to the shortest length possible in order to elimi-
nate any chance of falling over the edge of the parapet.
Before each use and after unusual occurrences, the
carrying handle (5) that is used for fastening the
safety rope must be inspected by an individual with
expertise in this area. The carrying handle (5) is not
permitted to exhibit any cracks, corrosion, notches or
other material faults.
The additional weights must be reliably secured with
the safety clamps (1 each at the front and rear) provid-
ed for this purpose.

6.2 Operating readiness
Hook up the strain relief of the power supply cord (1) into the spiral holder (25) and then check the basic
setting of the welding nozzle (9).
• The nominal voltage specified on the device (see technical data [2]) must match the supply voltage.
• The power cord (1) must be able to move freely and must not hinder the user or third parties during work
(trip hazard).
• The extension cables must be authorized for the utilization site (such as, outdoors) and be marked accordingly.
Take the necessary minimum cross-section for extension cables into account as required.
On-site generators for power supply
When using on-site generators as a power supply, please ensure that the on-site generators are grounded and
equipped with residual-current circuit breakers.
For the nominal output of the power plants, the formula “2 x nominal output of the hot-air welder” applies.
Power cord and extension cable
In cases of supply power failure, during work inter-
ruptions or when cooling down, you must swivel the
hot-air blowers (10) into park position and allow them
to engage there.
Take care to ensure that the hot-air blower lock (15)
engages.

6.3 Positioning the device
• Check whether the material to be welded is clean between the overlap on both the upper and lower sides.
• Then check whether the welding nozzle (9), drive/pressure roller (8), deflection roller (27) and press-
down belt (26) are clean.
• Swivel the hot-air blower (10) so it engages in the park position.
• Now raise up the hot air welder by the guide bar (22, 24) and move the device to the desired welding posi-
tion.
• Now position the welding plate (see scope of delivery[4.2]) and then swivel the track guide roller (16)
downwards.
• Take care to ensure that the track guide roller (16) is positioned parallel to the drive/pressure roller (8).

If the device was allowed to cool down beforehand, this will be followed by a static
display of the setpoints of the most recently used profile (the Basic profile is dis-
played when the device is first commissioned).
The heating is not yet switched on at this stage.
• Select the desired welding profile or define the welding parameters individually.
• Now switch the heating on with the heating On/O button (31).
After startup, the Start screen will appear briefly in the display, with the
version number of the current software release and the device designation.
• Once you have prepared the working area and the hot air welder in accordance with the description, connect
the hot air welder to the supply voltage.
• Use the main switch (19) to switch the hot-air welder on.
