NOTE: Many times the footing will not set early enough to support the cylinder
weight, so it must remain suspended. A poorly centered suspension or sling may
try to pull the cylinder out of plum, even though it is fully backfilled. This is why the
plumb of the cylinder should be re-checked often while backfilling, the suspension
should be reasonably centered, and should be braced back to the pit walls or
wedged with blocks at the top until the sling is removed. Do not use a sledge to
drive the wedges as the cylinder may be damaged.
8.
Install the reinforcement bar in the pit floor before the “top cap” of concrete is
poured to finish the pit floor. If this rebar is not installed, the top cap may sink into
the backfill beneath.
PIPING INSTALLATION
1. Install piping between the ram inlet port (in the pit) and piping entering the pipe
chase in the pit wall, and between the “stub up” out of the pipe chase to the power
unit discharge port. Piping should be steel with a minimum wall thickness of
schedule 40, and a diameter no smaller than the oil coupling connection on the
ram(s).
2. To avoid introducing harmful debris into the piping, do not use Teflon tape; use pipe
dope such as Loctite PST #567. Also, an air compressor should be used in the
piping previously installed to blow out any possible debris in the pipe chase which
my have been introduced during site construction.
3. Be sure to install at least one to two union fittings in the pit to allow for future
maintenance by providing a means to drop the pipe manifold without removing the
ram(s). A block valve installed near the riser in the pit will also prove useful for
future maintenance by providing a means to block oil in the piping from the power
unit.
4. It is best to leave enough space for a pipe wrench between the pit floor and the
bottom of the pipe run.
NOTE: For proper air-valve performance in APA (air-powered) models, the “IN” port
must be connected to an air supply line and the “OUT” port to exhaust only.
