WARNING
Sewage is a common mode of transmission for parasitic organisms that may
have the capability of causing communicable diseases. After coming in contact
with sewage or contaminated equipment, be sure to clean yourself with a disin-
fectant soap. Avoid sewage contact with skin abrasions, punctures, cuts, and
other open wounds. Wipe up and clean any spills and/or contaminated equip-
ment using a disinfectant soap.
! CAUTION
Failure to use two wrenches while loosening pipe fittings, couplings, and valves may
cause damage to the valves, fittings, couplings, and piping.
2. Using a pipe wrench, loosen the union (figure 1, item 1) and allow any effluent to drain into the suitable drain
pan.
3. Remove the pipe (figure 1, item 3) from the threaded gate valve (figure 1, item 2).
4. Remove the threaded gate valve (figure 1, item 2) from the remaining piping (figure 1, item 4).
INSTALLATION
WARNING
Removing components by means of wire brushing produces flying particles. These
particles can cause serious injury to personnel. Protective goggles, gloves, and
long sleeves must be worn at all times during wire brushing operations. Failure
to comply with this warning can result in serious injury to personnel.
1. Clean the threaded ends of the piping (figure 1, items 3 and 4) with a wire brush and apply antiseizing tape to
the threaded ends of the piping.
! CAUTION
Failure to use two wrenches while tightening pipe fittings, couplings, and valves may
cause damage to the valves, fittings, couplings, and piping.
2. Install the threaded gate valve (figure 1, item 2) onto the existing piping (figure 1, item 4).
3. Install the pipe (figure 1, item 3) into the threaded gate valve (figure 1, item 2).
