ZoomLock MAX

Press-to-Connect Refrigerant Fittings

General

ZoomLock MAX ﬁttings must be installed by an installer

who is appropriately trained and qualiﬁed to work on air

conditioning and refrigeration installations and certiﬁed via

the ZoomLock MAX training course. All installations must

be completed in line with local regulations and by-laws

governing the installation, and all applicable health and

safety practices must be adhered to. When using the press

tools, care must be taken to ensure hands are kept away

from the jaw during the pressing process. Always wear ear

and eye protection.

Important: Select the correct size of tube, ﬁtting and jaw

for the job. Ensure the ﬁtting and tube are kept free of any

dust or dirt and that the O-ring is undamaged. Check the

inner pressing contour of the jaw is free of dirt and debris.

Do not force tube ends together prior to making joints.

Joints should only be made on an unstressed pipework

assembly.

Remarks

• A joint is ﬁnished after one complete compression cycle

of the tool.

• Do not press any ZoomLock MAX ﬁtting more than

once.

• Pipework alignment must be completed prior to

pressing.

• Do not rotate joints after they have been pressed.
