Installation
Installation of the Inlet & Outlet DISS Assemblies
Inlet and outlet DISS assemblies must be installed in accordance
with NFPA 99 or CSA Z7396.1. An internal nitrogen purge must be
used during the brazing operation. The purge gas should flow away
from the DISS body. Brazing alloys per appropriate standards must
be used. Before brazing, wet rags must be wrapped around the tube
extensions next to the DISS body to prevent overheating and possible
damage to the DISS O-ring seals. Direct the flame away from the DISS
body. The DISS body temperature must not exceed 300°F to prevent
damaging the O-ring seals.
The system must be tested (per appropriate standards) to ensure
that no cross-connections have been made.
The system must be tested (per appropriate standards) for leaks.
Note:
Pressure in the system will increase or decrease with
temperature rise or fall.
Miss-connection of the gases could lead to serious
or fatal injury to patients. Following installation,
DISS connections must be tested for cross-connection (per appropriate
standards) to ensure that the intended services are correctly connected to
the appropriate service lines.
5.
The center of the rough-in box should be 60” in height above
the finished floor. Fasten the back box to horizontal braces
installed between the studs so that the front edge of the rough
in box will be flush or slightly recessed with the finished wall
covering.
6. Before brazing, remove the plastic tube caps from the DISS
assembly (risers) copper extensions. DISS assemblies must be
installed in accordance with “Installation of Inlet and Outlet
DISS Assemblies” above.
Sleep Lab Panel Installation
1.
Powerex Sleep Lab Panels may be plumbed in either direction
– with the patient (use) side on the left or the right. This saves
the plumber time and money.
2.
The rough-in (back box) is shipped with a cardboard dust cover
installed. You will need to remove the dust cover to install
the rough-in and perform the pressure test. The dust cover
should be re-installed after the pressure test to protect the
DISS connections until the wall covering (drywall, paint etc.)
is complete.
3. The DISS risers are shipped loose and must be installed in the
back box.
4.
Adjustable depth mounting flanges (top & bottom) should be
utilized to align front edge of box to be flush with the drywall
surface.

The system must be tested (per appropriate standards) to
ensure that no cross-connections have been made. The
system must be tested (per appropriate standards) for leaks.
Note: Pressure in the system will increase or decrease with
temperature rise or fall.
8.
After the system passes the leak test, install the labels provided
in the back box paying careful attention to the direction of the
gas flow (left to right, or right to left). The direction of flow
affects where you place Inlet and Outlet Labels in the back box.

9.
After the wall covering is complete, the dust cover may be
removed from the rough-in box and the hose assemblies and
front panel may be installed.
10.
Make sure the hose assemblies are attached to the
appropriate inlet/flow meter connection point, and
outlet/flow meter connection point. Failing to do so
may affect the patient and the sleep lab test results.
Note: Sleep Lab Panels may be plumbed in either direction –
with the patient (use) side on left or the right.
