Procedure
1.
Clean threaded surfaces and pour locations
should be with soap and water and
thoroughly dried before proceeding.
2.
Install two conduit runs
(one signal, one power) between the enclosure I/O casting
and AC power source (located in a safe area or in an explosion-proof box). See
drawing P011 for added details.
3.
Shake the sealing compound powder
well before mixing with water. The
recommended mix ratio is 5 parts powder to 1-part clean water, by weight.
4.
Place 25ml of 70°F water into a clean mixing container
and gradually add powder to
water while mixing with a slow-speed mixer or by hand with a spatula until a uniform
consistency is obtained.
•
A minimum amount of water should be used. Excessive water reduces
mechanical strength, increases shrinkage, and delays set time.
•
Failure of the cement to adhere indicates setting has begun. Do not attempt to
re-temper by adding more water. Discard cement and start a new batch.
5.
Apply compound
by pouring, casting, or using a mechanical dispenser. The sealing
compound hardens with an internal chemical-setting action in 18 to 24 hours at
ambient temperature. Working time of the sealing compound when the powder is
mixed with water is approximately 30 minutes at 70
°
F. If accelerated curing is
desired, low temperature oven drying at 180
°
F can be used. Do not expose the
sealing compound to higher temperatures, constant water immersion, or steam
environments while curing. If high humidity resistance is required in the cured
product, a moisture-resistant lacquer or silicone coating should be applied to the
exposed surfaces.
6.
Place Packing fiber around the ends
of each individual wire or cable ends to create a
dam for pouring the compound into the PAC Seal. This allows for the entire contents
of the PAK Seal to be encapsulated by the compound with environmentally safe,
non-asbestos material.
7.
LUBT-2 lubricant is recommended for use on threaded joints.
This lubricant is used
to prevent galling of the pipe threads when threading into couplings, junction boxes,
etc. It provides for undamaged male and female threads and a quick release when
parts are being disassembled. The thread lubricant should be a high-quality lubricant
used in temperatures ranging from -40
°
to +50
°
F, and is recommended for use in
hazardous locations. The PAC Seal Compound, packing fiber and LUBT-2 are available
8.
For enhanced reliability
of the Purge unit, an AC line conditioner is recommended.
AC power lines should be no smaller than 14 gauge and have a TRUE EARTH
GROUND.
