1.0 STORAGE
Ideal storage is in a warehouse with a relatively dry, cool location. Store flanged units face
down on a pallet or wooden platform.
If storage is outside, keep expansion joint protected in waterproof protected crate until
ready for installation. Keep expansion joint protected from external elements such as di-
rect UV sunlight and/or animals from nesting.
Do not lay other boxes on top of expansion joint or expansion joint box.

ANDLING
:
Do not lift expansion joints with ropes or bars through bolt holes. Lift through the
bore using padding or saddle, so that weight is evenly distributed during installation.
Make sure crane cables (or forklift tines) do not contact rubber surface.
2.2.1 Do not let expansion joint sit vertically on the edge of its flanges for any peri-
od of time.

REPARATION
:
It is acceptable ( but not necessary ) to lubricate the expansion joint flanges with a
thin film of graphite dispersed in Glycerin or water to ease disassembly at a later
time. (
It should be noted that petroleum lubricants should not be used on expansion
joints .)

NSPECTION
Check outer cover of expansion joint for damage before placing in service. The
cover is designed to keep harmful materials from penetrating the carcass of the
joint. Penetration of cover by harmful materials can cause premature failure of the
expansion joint tube. If outer cover is damaged during unpacking or installation,
contact Proco Products, Inc. by phone 209-943-6088, by facsimile 209-943-0242, or
by e-mail sales@procoproducts.com, to determine a course of action before joint is
put in service.

LIGNMENT
:
Check piping system alignment ( where rubber expansion joint will be located ) to de-
termine offset before installation. Pipe flanges should be lined up within a maximum
of

1/8". If this maximum

1/8" misalignment is exceeded, the piping should be cor-
rected before installation of the expansion joint takes place.

UPPORTS
:
Check piping supports where rubber expansion joint will be located. Piping to and
from rubber expansion joint must be properly hung and guided so that its weight is
not transferred to the joint.
