Replacing Cylinders; Single Pane Glass - Hussmann Elite Series Installation & Operation Manual

REPLACING CYLINDERS —

SINGLE PANE GLASS

When cylinders need to be replaced, the lift-
ing force of the cylinder must be known . The
lifting force can be determined by the data
printed on the cylinder being replaced .
NOTICE
Cylinder rods must point down so oil will
lubricate the rod and seals. Failure to
lubricate will severely shorten cylinder life.
Cylinders are a wear item.
They are designed:
• to support the glass when fully open.
• to allow the glass to come down
(or close) slowly.

if support cylinders are worn and need to
be replaced. If the glass does not stay in a
raised position, have the cylinders replaced.
Each front curved glass section weighs about
40 lb (18 kg). To prevent glass from falling
during installation, use or maintenance, and
causing injury to customers or personnel,
Hussmann recommends one person hold the
glass in a raised position while the other
person performs cylinder replacement.
Support the front glass at all times until cyl-
inder is replaced or the glass is lowered.
Once cylinders are removed, front glass will
have NO support to maintain it in a raised
position.
