SafeRoom
8/18 Installation:
1. Locate and cut the intake vent hole through the shelter/safe room wall insuring
that there is an electrical power source within the range of the power cord length.
A. Minimum diameter of 6.75-inch/172-mm
B. Minimum height location as to insure that the intake vent is located at least
24-inch/600-mm above any outside flat surface.
2. Layout and drill holes for lug Flange Disc, taking care to insure that the
Flange Disc & the hole pattern is centered over the intake vent hole.
3. Drive the respective lug bolt anchors into their respective holes.
4. Apply a liberal amount of caulking compound to the mating side of the Disc-mounting
flange.
5. Secure the Disc Flange and wall bracket and tighten
6. Mount the filtration unit into the wall bracket
7. Remove the plastic port plugs from the filtration unit and install the intake
hose between the Disc Flange and the intake side of the filtration unit.
Overpressure
Valve Installation:
1. Locate and cut the exhaust vent hole through the shelter wall Minimum diameter
of 3-inch/76-mm.
2. Layout and drill holes for lug bolt anchors taking care to insure that the
overpressure valve hole pattern is centered over the exhaust vent hole.
3. Drive the respective lug bolt anchors into their respective holes.
4. Apply a liberal amount of caulking compound to the mating side of the overpressure
valve mounting flange.
5. Secure the overpressure valve and tighten the anchor bolts to their rated
torque using a cross torque pattern.
Operation:
Electrical power
1. Connect the power cord to the control panel power socket
and plug into a working power source, switch on the lighted
power switch.
Automatic battery back up:
2. Connect the battery jumpers to the control panel battery
socket and connect the clip leads to a 12-volt battery/ 65Amp+.
A. Make sure the positive clip lead (+) is to the positive
post of the battery (+). (Readand understand the caution
below)
B. Switch on the lighted power switch. If necessary toggle
the blower control push button to on so that the system is
running.
CAUTION: NEVER ALLOW THE BATTERY CLIP LEADS TO CROSS
Allowing the battery jumper clip leads to cross while connected
to the control panel battery socket will burn the 8-amp fuse.
CAUTION: LEAD ACID BATTERIES RELEASE HYDROGEN GAS
Use only sealed unvented batteries / Or Deep circle/Dry Sealed
Bateries are recommended.
Hand Operated Bellow:
The SafeRoom 8/18 hand operated bellows with an output is
50-m³/1766 ft³ pr/hr at 50 strokes per/min. Physical
size: 304-mm/12-inch diameter, having a 179-mm/7-inch stroke.
The procedure is to remove the filtration unit from its quick
disconnect wall brackets and install the manual pump will
quick couple directly to the top of the filtration unit.
This places the pumps operating handle at waist height for
sustained hand pumping operation.
Overpressure valve:
The Overpressure Valve has two functions:
1. It creates an overpressure in the shelter by adding the
proper resistance to the outgoing airflow. The valve is normally
closed and will not open unless the air pressure inside the
shelter is greater than the outside air pressure.
2. It automatically closes when a positive pressure wave
from an explosion or wind exceeds the internal pressure of
the shelter. When the outside air pressure returns to normal
the overpressure valve automatically returns to its open
state.
Positive Over-Pressure Test:
Check and make sure the shelter is sealed/closed.
After turning the system ON, wait approximatly 10-15 minutes & then
check that the Over-Pressure valve LATEX Foil is going flapping
up and down. If it is not, wait and recheck at 5 minute intervals
Note:
It is recommended that the port plugs be left in the filtration
unit until
time of use to increase the life of
the activated carbon & the HEPA Filter as well.
