ISSUE POSSIBLE CAUSE(S) SOLUTION
1 The curtain sags and/or falls
into the pit after the leveler has
stored.
The hook and loop fastener has
come loose between the main
curtain and the top section.
Re-attach the hook and loop fastener from the middle out. Make
sure the main curtain is evenly spaced and rmly pressed to the top
section.
One or more of the spring clips has
detached or broken from the leveler
frame.
Examine the spring clip to determine if it can be remounted.
Remount or if spring clip is broken, contact Rite-Hite Environmental
Enclosures Parts Department for replacements.
2 The width of the main curtain
and top section are not the
same width as the leveler.
Main curtain and top section may be
misapplied or on the wrong leveler.
Make sure components are being applied to the correct leveler. If
correct, re-apply and evenly space the main curtain and top section.
Main curtain and top section are
wider than the leveler.
Make sure components are being applied to the correct leveler. If
correct, trim edges of each for a better t.
3 The unit is not sealing the sides
of the pit well.
The side seals may be damaged. Check if the side seals have been bent or torn from the wall. They
can be reattached with concrete anchors (supplied by others) or
new side seals can be purchased from Rite-Hite Environmental
Enclosures Parts Department.
The side seals may be the wrong
height.
The side seals come in 16 in (406 mm), 24 in (610 mm) or 34 in
(854 mm) heights and are trimmed to t the pit. Side seals that are
too tall of can be trimmed for a better t. Side seals that are too short
need to be replaced.
4 The toe guards, safety legs,
end load legs, or other obstacles
hit the curtain when leveler is
coming down.
This is normal contact between
parts. The main curtain and top
section are designed to move and
ex with the leveler components.
The PitMaster II is reinforced to allow safety or end load legs to
perform their function without major wear or damage to the main
curtain or top section. It is normal to see some discoloration or wear
on the curtain from these legs.
5 The safety or end load legs are
pulling o󰀨 the curtain or are
wearing through the curtain.
The building may have high positive
pressure or the main curtain may
not be folding properly when the
leveler moves.
Make sure there is enough tension on the shock cord connected
to the back of the main curtain and the leveler stringers. The shock
cords should be pulled tight and not sagging The spring clips on
the leveler stringers may need to be moved further into the pit to
increase tension.
The building may have high
negative pressure and is pushing
the main curtain too far into the pit.
When there is a high negative pressure, the bottom aps of the main
curtain can be attached to the ller panels or front of the pit. This
prevents the main curtain from pushing too far into the pit.
Refer to
"Non-Standard Levelers" on page 3 for more
information or contact Rite-Hite Applications.
6 Bottom of main curtain catches
on lip keepers or subframe.
The bottom of the main curtain may
not be trimmed correctly.
The main curtain has aps at the bottom which need to be trimmed
to correctly t and seal around pit obstructions. Make sure all 3
layers of aps have been separated to ll in the space around the
subframe. Trim any that are catching.
