Depending on the valve length the shaft has to be adjusted. The recommended way to find the correct shaft lengths is shown in the pictures below.
– At first, push the shaft forward so that the pilot drill touches the pipe surface.
– Measure the lengths between the lower shoulder of the shaft and the upper device body.
– The measured distance should be between 100 – 170 mm
– Adjust the length of the shaft if necessary as shown in chapter 4.2.1 and 4.2.2
The feeding distance is recommended to be at least 35 mm.

Operational Instructions

4.1 Branch Preparations before the Hot Tapping
Before the drilling process can start, the branch of the decided dimension has to be prepared. Keep in mind that the branch size should be at least one nominal size smaller than the main line.
4.1.1 Removing the insulation
– If the main line is insulated, remove the insulation and clean the pipe surface.
– Remove the insulation far enough in order to have sufficient space for the welding. 4.1.2 Adjusting the Hot Tap Valve
– Adjust the lower end of Danfoss Hot Tap Valve to the round of the main line using a grinding machine.
– It is important that the valve is handled in a proper way to prevent grind or other foreign particles to get into to valve. It is suggested that you insert a rag to prevent damage of internal parts. Before welding, the rag must be removed.
– The valve has to be fully open during the adjustment.
4.1.3 Welding of the Hot Tap Valve to the Main Line
– The hot tap valve can be welded on to the pipe in every possible direction, but the angle between the center line of the main pipe and the valve axis must be 90°. The valve has to be welded by certified welder. Welding technology electric arc welding or TIG welding, with low current as possible. Ensure surface along joint line is free of oxides and grease.
Make sure that no welding material enters the valve. Valve need to be welded to the main pipe by single run closed fillet weld. Avoid multiple run fillet welding to prevent overheating and potential weld cracks.
The ideal relation between the weld throat thickness and wall thickness of both welding parts need to be considered (see picture 1).
– Before welding, check the closing mechanism of the valve.
– During welding the ball valve must be open.
– The valve has to be welded on by electric arc welding.
– Make sure that no particles are entering the valve.

• Considered welded part with the smaller wall thickness (main pipe thickness or valve welding end thickness)
  WARNING: Avoid multiple run fillet welding to prevent overheating
  4.1.4 Testing the Valve
  – Before starting the drilling process it is mandatory to test the closing mechanism of the valve.
  – Use the proper key to close the valve and open it completely afterwards
  WARNING: NEVER start drilling if the valve doesn’t close or open completely 4.2 Assembly of the Drilling Device
  Danfoss Hot tapping machine is delivered in a box, including all the items described in chapter 3.2 plus additional tools for (dis)assembly and pressure tests.
  4.2.1 Assembly of the Shaft for hole saws > 32mm
  – A proper hole saw ③ for the dimension according to chapter 3.3 shall be chosen.
  – It shall be connected winding clockwise to the drill chuck ④.
  – When connected, it shall be released so much that the closest turning pins E can be pushed through the holes F at the bottom of the hole saw.
  – The drill chip magnet ② can be put around the pilot drill ① the drill is pushed to the hole of the chuck aligning the groove B and the screw A.
  – Finally, the drill is locked by tightening the screw A.
  – The drill chuck shall be connected on the top of the drilling shaft ⑤ or, if used, the shaft extension ⑦.
  – If the valve should be so long that the shaft length would not be long enough to enable the drilling, the useable shaft length can be extended by the feed extension socket ⑥
  at the end ot the shaft or by adding shaft extensions ⑦ at lower end of the drilling shaft ⑤.
  CAUTION: Make sure that the drilling shaft is screwed in completely so that chuck pins ⑧ are alining with the chuck bottom.
  NOTICE: Check that the pilot drill is neither too big no too small for the used hole saw. A too long pilot drill increases the feeding distance unnecessarily while a too short drill doesn’t provide the guidance for the hole saw.
  CAUTION: If the pilot drill it too long it might be impossible to close the valve !
  4.2.2 Assembly of the shaft for hole saws < 32 mm
  – For hole saws <32mm and >24mm use the small chuck ⑧. The smallest chuck ⑨ should be used for hole saws <20mm.
  – Screw the hole saw ③ to the chuck ⑧ or ⑨ depending on the hole saw size.
  – The magnet ② has to be put around the pilot drill ① and pushed into the hole of the chuck ⑧ or ⑨.
  – The groove in the pilot drill ① has to be alligned to the screw G.
  – Attach the assembly to the shaft ⑤. Use shaft extensions ⑦ or the feed extension socket ⑥ if necessary.

4.2.3 Assembly of the Danfoss JIP Adapter Socket
The Danfoss JIP Hot Tapping Adapters are delivered in a tool box including all the sizes from DN 15/20 to DN 100. For the sizes DN 25 as well as for DN40 reduction sockets have to be added to adapter of the next size as shown in the following picture. 4.2.4 Assembly of the Device to the Hot Tapping Valve
– The adapter has to be connected to the thread of the valve by first winding with hand and tightening it tenderly using the wrench. Because the tightening O-ring, it is not necessary to use much force while connecting the parts.
– Prior connecting the adapter to the valve, a proper central drill, hole saw, chuck and drill shaft have to be assembled together as shown in chapter 4.2.1- 4.2.2.
– When all parts have been screwed on, test that it is still possible close the valve as shown in the picture below ! Dismantle the machine and adjust it again if the valve cannot be closed !
– Remember to FULLY open the valve after that ! 4.2.5 Installing the Feed Unit
– The feed device ⑦ is used to create a feed force for the drillling.
– The feed thread has to be winded to back position completely by turning the feed wheel ⑧ counter-clockwise.
– The adjusting socket ⑨ shall be connected by first alignig the grooves and the guide screws A and there after slided to the closest locking groove B at the machine body.
– The excessive clearance is removed by turning the feed wheel ⑧ clockwise.
– Measure the feed distance as described in chapter 3.3 and adjust it by shaft or feed extensions if possible. 4.2.6 Installing the Driving Unit
– The shaft square shall be aligned with the drive square hole and then connected and locked using the connecting screw.
– The right rotating speed is chosen for the drilling according the table below.
– For the pilot drill the maximum rpm is suitable.

4.3 The Hot Tapping Process
After the machine is assembled, all the connections shall be checked and controlled. The user can continue with the following steps after that.
4.3.1 Pressure Test
Prior the actual branching a pressure test must be conducted to ensure the tightness of both the welding seams of the valve and the drilling equipment.
– A hose ① of cold water or pressurized air is connected to the coupler of the body.
– The control cock ② is opened to let the pressure in.
– If desired, close the control cock ② and mount the pressure gauge ③ in order to monitor a possible fall of pressure
– After the test, the test fluid is released through the same control cock ②
– In case of an occuring leakage, it is not allowed to start the drilling process until the failure is eliminated 4.3.2 Starting the Driling Process
The drilling process starts by creating a center hole with the pilot drill :
– The maximum rpm is chosen from switches and.
-The feed is started lightly by very slowly turning the feed wheel clockwise.
– Feed very slowly in the beginning to ensure a good centering of the central drill.
– A penetration of the pilot drill through the main pipe wall can be observed by observing the pressure meter ⑦. Raising of the needle indicates the penetration.
– An adequate feed using the max. rpm must be continued until the pilot drill gets through the wall of the main line.
– After the pilot drill is through, the turning speed for the hole saw has to be adjusted as described in chapter 4.2.6
– Start the feeding with the hole saw carefully and keep a fixed stand. Extra caution must be pointed to cope the reaction forces. Pull the machine in the direction shown in the picture to compensate the force.
– When the drilling advances, the feed rate can be slightly accelerated until at the end of the drilling.
-The final penetration of the main pipe wall can be confirmed by pushing the shaft forward firmly without turning shaft – When it advances, the hole must be free. CAUTION: The drive must never be locked to continuous run, since the variations of machining forces may cause an unexpected lost of control of the drive and thus cause severe damage to the operator. Be aware of the reaction forces from the cutting.
WARNING: The drive and the shaft must always turn CLOCKWISE. Accidental opening of the connecting threads of the shaft may cause severe damage to the operator.
WARNING: NEVER use lever tools at the feeding wheel and feed very carefully ! When the hole saw gets stucked, stop feeding or turn the saw a little bit backwards. Continue feeding slowly ! 4.3.3. Adjusting the Feed
– If the feed extent runs out and feed wheel ① can not be turned anymore, the adjusting socket ② must be released and locked to a lower groove.
– If the pressure is >12 bar, use the chain block for this operation! The use of the chain block is explained in chapter 4.6.
– At first, switch of the driving unit.
– Screw the feed wheel ① counter clockwise.
– Don’t unscrew it too much as the hook of the pilot drill might break. – Grip the adjusting handles ③ and push them firmly forward. Turn the adjusting socket ② until it can be released.
– Push the adjusting socket down in the direction of the next groove.– Continue to turn the feed wheel ① counter clockwise until the next groove can be reached.
– Lock the adjusting socket ② to the next groove by turning it clockwise.
Warning: If you are unsure about the forces acting on the shaft while releasing it, use the chain block for this operation. From the manufacturers experience, it is advisable to use it at a pressure >12 bar. See chapter 4.6 how to use the chain block. 4.3.4 Releasing the Feed Unit
After finishing the drilling, the drive shall be released from top of the assembly. In lower pressures, this can be done by hand. For higher pressures

12 bar it is highly recommended to use the chain block.
– Both of the the adjusting handles ③ shall be gripped, pushed forward and simultaniously turned counterclockwise to release the adusting socket.
– The socket can now be reversed by sliding the power screws completely off from the drill body
– Release the shaft completely. The chuck inside the drilling chamber stopps the shaft from comming out.
Warning: If you are unsure about the forces acting on the shaft while releasing it, use the chain block for this operation. From the manufacturers experience, it is advisable to use it at a pressure >12 bar. See chapter 4.6 how to use the chain block. 4.3.5 Closing the Valve and Releasing the Pressure
– The valve has to be closed completely by turning the ball using proper allen key and turning it 90 degrees. Since the ball in the hot tap valve has no automatic stop, you may have to adjust the position of the ball until it is in correctly closed position.
– The tightness can be controlled by opening the control cock.
– Connect the hose to the control cock and open it to release the pressure
CAUTION: Keep enough distance to the hose while releasing the pressure to protect yourself. Make sure the valve is completely closed !
4.3.6 Disasembling of the Machine
The machine is dissasembled in the oposite order as shown in chapter 4.2. At the end, the cut out piece shall be removed.
– The pilot drill is loosened by opening the retainer screw using the proper allen key
– The central drill is pulled out and the coupon is removed around the drill stem.
– The drill chips are cleaned from the gathering magnet 4.4 Creating the New Branch
For creating the new branch, follow the valve manufacturers instructions carefully.
– When the Hot Tapping has been acomplished, the new line can be connected to the Danfoss hot tap valve by electric arc welding.
– During that operation, make sure that the sealings inside the valve are not overheating.
– After the welding and when the line is approved to start operatiing, open the valve first very slowly.
– Open the valve COMPLETELY afterwards.
– After the valve is completely open, screw the top plug. It is recommended to weld the plug to the valve neck by single run closed fillet weld. Fill the gap between top plug and valve neck completely. Avoid multiple run fillet welding to prevent overheating. 4.5 Maintanance Plan and Spare Part List
Before and after every hot tapping, the whole device should be visually inspected and maintained. Don’t start the drilling work without inspecting the device before. Never start the drilling if any damages are observed. If any technical problems occur don’t hesitate to contact the manufacturer Danfoss.
