Conduit Runs
Conduit can be run either vertically or horizontally. But either way the conduit must be sealed properly to
maintain the explosion proof integrity of the unit. The following paragraphs explain the proper way to install a
conduit run and the sealing fittings.
Horizontal Conduit Runs
Install the fitting with covered filling opening facing up. Remove the threaded cover and pack Adaco
fiber around and between cables at both ends of fitting to block the flow of cement into conduits. Packing fiber
must not project into the main cavity of fitting. The cavity length free of packing fiber must be at least equal to
inside diameter of conduit but not less than 5/8".
Mix the cement per label instructions using the enclosed shipping container. Fill the container with clean cold
water to "water line" (make sure not to exceed required amount of water). Gradually pour cement from the
plastic bag into water and stir thoroughly for proper mixture. Fill the fitting in one continuous pour to the top of
filling opening within five minutes after mixing cement. Tamp with a blunt stick to expel any air bubbles. Install
and tighten filling opening cover.
Fittings requiring more than 16 oz. of cement must be filled from a single mixture of cement and water. Do not
pour in stages.
Water-mix sealing compound should not be poured or installed at temperatures below 35F. Adaco
Caution
!
no. 1 sealing cement must be used as a part of Adalet UL listed fittings.
Vertical Conduit Runs
Install the fitting with angled fill plug or cap fill plug towards the top. Remove angled fill plug, large hole plug or
threaded cover. Pack Adaco packing fiber around and between cables at lower end of sealing fitting to block flow
of cement into conduit. Packing fiber must not project into main cavity of fitting. Install and tighten large plug or
threaded cover with fill plug facing up but do not install fill plugs at this time.
Mix the cement per label instructions using the enclosed shipping container. Fill the container with clean cold
water to "water line" (make sure not to exceed required amount of water). Gradually pour cement from the
plastic bag into water and stir thoroughly for proper mixture. Fill the fitting in one continuous pour to the top of
filling opening within five minutes after mixing cement. Tamp with a blunt stick to expel any air bubbles. Install
and tighten fill plug.

Gasketing
This unit is a custom application and has a NEMA 4 gasket installed in a slot in the door. This gasket prevents
water from entering the enclosure and damaging or destroying the electronics inside, therefore it must be
inspected periodically to make sure it has not cracked, split, or deteriorated from heat, cold, or chemicals.
If the gasket becomes damaged, it must be replaced as soon as possible (damage is not covered by warranty).
The enclosure was shipped with grease on the machined surfaces. Do not remove it. These surfaces must fit
together tightly to maintain the seal on the enclosure. For that reason, the machined door surface and enclosure
must not become scratched, pitted, or damaged. It is recommended that a white lithium grease be used to keep
these surfaces free from contaminates, etching, and moisture.
Note:
Do not use a petroleum based grease. If in doubt, contact your dealer.
