Make sure to use torque wrench to tighten
the service kit.
Locate the ball valve that needs to be tted with the
service kit.

located to the lowest permissible pressure, governed by
the suction low pressure safety switch.
In case it is impossible to pump down the section of the
system, please contact Danfoss for further instructions.

Below extra cautions should be followed
during the installation of service kit in CO

systems
• Use appropriate safety equipment, such as: Safety glasses, gloves, ear
protectors and where necessary a helmet, before operating the GBC during
service.
• Be aware of your surroundings BEFORE removing the cap from the standard
GBC ball valve. ENSURE that you do not occupy the area in front of the spindle
to avoid any potential danger of being hit by the spindle and provide a
means of stopping the spindle should it become ejected from the body after
the cap has been removed (in extreme cases).
• Take extra care when working on steps or in conned spaces.
• When working at height – Consider the use of a suitable safety harness.
Generally, all work should be carried out in a well-ventilated area. Ideally, the
technician should use a personal R744 detector to ensure that the area is safe to
work in.
All tools and equipment such as hoses should be rated for the pressure of the
system, R744.
The servicing technician should be familiar with the system and should
understand how sections of the system are safely isolated. This includes the eect
on the system when closing valves and the potential for trapping liquid R744
between closed valves.
Welding or brazing should not be attempted on the system until fully
de-pressurized.
