Conduit Runs - Rice Lake IQ plus 310A XPCD Technical And Service Manual

2.3.2

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 packing
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.
Caution
!
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 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.
