Appendix A

Electrical connections require an approved explosion proof sealing fitting and packing around wires and cables (for incoming

power for the analyzer electronics, power failure alarm relays, set point alarm relays and 4-20mA signal output) coming into and

out of the explosion proof enclosure that houses the interconnection PCB. Further full compliance with hazardous area electrical

code requires the wires and cables to be protected by conduit. Advanced Instruments recognizes that safety is an important

factor and offers for the convenience of our customers an approved sealing fitting and packing material as options.

Explosion Proof Packing Fiber ( non-asbestos )

For use as packing at the hub of sealing fittings. Note: These instructions are supplied

from information and data which we believe is reliable and is given in good faith. Since

our methods of application and conditions under which our products are put to use are

beyond our control, we are not able to guarantee the application and/or use of same. The

user assumes all risks and liability in connection with the application and use of our

products.

Directions: Tamp packing fiber between and around conductors where they enter fitting

to prevent leakage of the liquid cement. Leave enough space in the fitting for length

equivalent to the inside diameter of the conduit but, not less then 5/8”.

Caution:

¾ Avoid getting in eyes or breathing dust.

¾ Use barrier cream, gloves and long sleeve shirts if dust or fiber is irritating.

¾ Prolonged contact may cause lung, eye or skin irritation.

Explosion Proof Sealing Cement

Directions:

Tamp packing fiber between and around conductors where they enter the sealing fitting to prevent leakage of

liquid cement. Make sure conductors are not

in contact with each other or with fitting wall. Leave space in the fitting for a

sealing length equivalent to the trade size of the conduct seal but not less than 5/8”. Fill marked shipping container with clean

cold water to the “water line” (35 ml to be precise). Caution: Do not exceed the required amount of water. Gradually pour

cement from the plastic bag into the water and stir thoroughly for proper mixture. Fill fitting completely within five (5) minutes

after mixing, then tamp with blunt stick to expel any air bubbles. Close up any opening in the fitting to insure integrity of the

seal. Fittings requiring more than 10 oz. of cement must be filled from a single mixture of cement and water. DO NOT POUR

IN STAGES. Allow cement at least 72 hours to cure.

Warning: At least five threads must engage on all fill plugs.

Caution: Water-mix sealing compound should not be poured or installed at temperature below 40F (4C). Maintain

temperature at or above 40F for at least 72 hours after pouring. CSA certified when used with any CSA certified sealing fitting.

Adaco No. 1 sealing cement must be used as a part of any Adalet UL listed fitting.

Notice: This instruction is supplied from information and data which we believe is reliable and is given in good faith. Since the

methods of application and conditions under which our products are put to use are beyond our control, we are not able to

guarantee the application and/or use of same. The user assumes all risks and liability in connection with the application and

use of our products.

Caution:

¾ Prolonged breathing or ingestion may cause internal obstruction, seek medical care.

¾ Do not get into eyes or on skin – flush for 15 minutes.

¾ Large amounts on skin when hardening may burn.

¾ Use adequate ventilation.
