PLUS 115
5.3 INFORMATION ABOUT ACCESSORIES
Two collaring heads are available for the PLUS 115. They cover collar diameters from
54mm to 115 mm / 2” to 4”. Within the diameter range, each collaring head is freely
adjustable to any required dimension. Once adjusted, the settings will produce accurate
collar diameters repeatedly.
Instructions for forming tees in various combinations of parameters are listed in the PLUS
115 capacity and instruction chart at the back of the manual. However, for processing
the largest run tube dimensions, the collaring head must be properly lubricated and the
instructions for the annealing must be followed. Use of improperly or poorly lubricated
collaring head may overload the tool!
6. LUBRICATION
In order to prevent device overloading, the lubrication of the collaring head is essential.
Lubrication also reduces wear of the collaring heads and hole drill and ensures that the
collar is formed correctly. T-DRILL recommends use of T-DRILL lubricant. The lubricant
should be applied generously:
1. To the cutting edges of the drill before each drilling.
2. To the forming pins before each collaring operation.
Use safety gloves when operating with the machine.
NOTE!
¨
Your PLUS 115 is supplied with lubricant in a convenient plastic squeeze
bottle. Additional lubricants are available from T-DRILL.
6.1 FLUSH OUT LINES
After the collars are made, all lines must be flushed out before the system is put into
operation in order to remove any lubricant residue and metal chips from the lines.
7. BRAZING AND TORCH RECOMMENDATIONS
Due to the height of the extruded collar, soft solder can not be used to join the branch
tube to the run tube. Use only a recommended brazing material. T-DRILL recommends
the use of brazes and flux as prescribed by the Copper Development Association with the
silver content of the brazing alloy, as specified by them.
NOTE!
¨
Temperatures required for brazing are higher than the ones required for
soft soldering. The torch used must be capable of heating the joint area to 600 -
800 °C (1100-1500 °F). All brazing on copper sprinkler systems must conform to
requirements of NFPA-13.
