Claw Medical Vacuum Systems
installation
Disconnect, tag and
lockout power before
attempting to install, service, relocate or perform
any maintenance.
Do not lift or move unit without
appropriately rated equipment.
Be sure the unit is securely attached to lifting device used.
Do not lift unit by holding onto tubes or coolers. Do not use
pumps to lift other attached equipment.
Installation of inlet / outlet air
plumbing from the system and
electrical connections must be in accordance with National
Fire Protection Association (NFPA99) Code Compliance for
Medical Gas Breathing Air (Level 1).

1. The vacuum system must be located in a clean, well lit
and well ventilated area.
2. The area should be free of excessive dust, toxic or
flammable gases and moisture.
3. Never install the vacuum system where the surrounding
temperature is higher than 104° F or where humidity is
high.
4. Clearance must allow for safe, effective inspection and
maintenance.
5. If necessary, use metal shims or leveling pads to level the
system. Never use wood to shim the unit.
6. The frame is drilled to allow bolting to the floor. Secure
it as necessary. Rubber composite isolation pads should
be used to minimize transmission of noise and vibration
to the building. Additional measures for isolation may
be required. Drill a hole through the isolation pad and
center it under the mounting point.
7. Some systems are built with multiple frames and must be
installed and the air and electrical connections between
the frames made at the time of installation. Be sure to
install the system in the same configuration as shown on
the system drawing so that the flexible connection hoses
and electrical lines will fit.
VenTilaTion
1. If the vacuum system is located in a totally enclosed
room, an exhaust fan with access to outside air make up
air must be installed.
2. Never restrict the cooling fan exhaust air. Maintain the
clearance listed above.
3. Never locate the vacuum system where hot exhaust air
from other heat generating units may be pulled into the
unit.

hazard. Make sure
the system is grounded in accordance with NEC and
local requirements.
All electrical hook-ups must be performed by a qualified
electrician. Installations must be in accordance with local and
national electrical codes. Make sure power supply conductors
are sized adequately for full system demand.
PiPinG
The system may have temporary shipping supports in
place. These should be removed when the system piping
is connected to the building piping. Appropriate supports
should be added to the system when building tie in is
completed.
The system has a single point inlet with a flexible connector.
Each pump is supplied with a flexible connector for tying
in to the system exhaust. A drip leg should be placed in the
exhaust as close to the system as possible or multiple drip legs
can be used at each pump exhaust connection. The drip leg
must prevent collected condensation from draining back into
the pump or pumps.
1. Make sure the piping is lined up without being strained
or twisted when assembling the piping for the system.
2. The exhaust piping should be kept as short and have the
least restriction possible. The flex connector supplied by
Powerex may be repositioned (changed from vertical to
horizontal and the elbow turned or removed) if desired
to achieve a more effective installation to match the field
installed exhaust piping. Repositioning is desirable if the
final system plumbing design can be shorter by doing so.
3. Never use any piping smaller than the pump connection.
To determine the minimum required pipe size for a
vacuum system exhaust, calculate the equivalent straight
length of the run. Never use a pipe size smaller than the
flex connector supplied by Powerex or smaller than the
size shown in the 100 foot column on the chart for the
CFM of the pump. The equivalent straight length is the
length of all the pipe needed from the flex connector to
the final outlet plus a factor for each elbow, cross or tee.
Pipe must be smooth ID. If rough pipe is used, increase by
one size.
4. If a grating or grille is used at the end of the exhaust
pipe, make sure its open area is at least equal to the area
of the exhaust pipe.
