MODEL: Pressurized Housing
PPFD8C

DESCRIPTION:

The PPFD8C is a 24 VAC pressurized housing enclosure
constructed of .125 Engineered plastic, aluminum and stainless
steel. All plastic components are designed to be UV stable; the
housing top is rated at 94VO. The unit measures 11.5" (w) by

12.9”(h) with a weight of 8 lbs. The housing is capable of
containing a maximum of 5 psi of nitrogen gas injected through a
Schraeder valve located at the top of the unit. A pressure relief
valve, located under the vented top cover, is designed to release
pressure in excess of 5 psi. A 10-pin hermetic connector located
in the center of the top coupling bracket contains 10.2” long leads
for all incoming power and video connections. The leads are
supplied with a standard BNC and (2) screw-down connectors.
The housing is supplied with standard dual 25 watt heater and (2)
circulation blowers. Service to the unit is accomplished by
removing the lower dome and ring assembly.

PRODUCT INSTRUCTIONS

NOTE: Be sure to periodically examine the unit and the
supporting structure to which it's attached. If the
dome shows any signs of wear, such as stress
cracking, it should be replaced immediately.

GENERAL INSTRUCTIONS:

Tools Required: .100" Flat Head Screwdriver
Phillips Head Screwdriver
7/16" socket

Preparing Mounting Brackets

1. Carefully remove the housing from the packaging material.
Check to be sure all parts are present, and that there is no
damage to the unit.

2. The standard model is designed as a pendant mount housing
with a 1.5" NPT housing coupling provided (to be used with a
standard 1.5" (NPT) pipe. The housing can also be used with
other brackets designed with 1.5" male pipe threads, such as
the PWM20G and PWM20 Panasonic wall mount brackets.

3. Install the pendant pipe or wall mount bracket in the desired
location.

IMPORTANT SAFEGUARDS

NOTE: Remember that the PPFD8C is a pressurized enclosure.

To prevent damage, care should be used at all times
when handling this product.

1. Inspect the enclosure upon opening the box to be sure that the
unit has not been damaged during shipping. Domes that have
been cracked or show any signs of damage should be
replaced immediately.

2. Always use safety goggles when servicing the unit.
Never use an unregulated gas supply to pressurize the

enclosure. The valve should be regulated with a

!

maximum of 10 psi output.

Be sure the bracket is properly and securely
mounted to a supporting structure capable of
rigidly holding the weight of the entire unit.

4. Pipe threads should be clean and rust free. Although a
hermetic connector protects the inside of the enclosure from all
moisture, it is still recommended that a thread sealer be used
on the threads of the housing coupling. Attach the housing
coupling to the bracket or pendant pipe (Figure 1).

5. Open the housing by loosening the (9) captive screws located on
the housing ring next to the lower clear dome. Twist the dome
slightly in a counter clockwise motion to remove (Figure 2).

8. Attach the unitized camera to the quick-release bracket. Secure
the safety screw (Figure 5). Connect the BNC and power cables.
Make sure all wiring is clear of the blowers and heater on the
housing bracket. Use the cable tie provided to secure the wires
and connectors.

6. Spacers are provided to adjust the level of the WV-CS854
camera. Attach the spacers, two-high, to the quick-release
bracket (Figure 3).

Figure 3

7. Connect the quick-release bracket to the spacers using the (4) 8 x
32 x 1/2" bolts and #8 star washers (Figure 4).

9. A small 2” section of humidity sensitive paper is included in the
housing packet. Tape this to the side of the pan/tilt unit assembly
or inside the housing a visible location. The tape will appear blue
in tint when the humidity is low and turn pink under humid
conditions. This can provide a check to confirm that the housing
is sealed properly. The paper requires about 30 minutes to adjust
to the appropriate color.

10. Clean the inside of the dome, with the tex-wipe provide. Reattach
the housing dome and secure the (9) captive screws. Do not
overtighten the screws. Tighten only to the point at which the
gap between the ring and the housing top closes. Each screw
should then be turned 1/2 rotation beyond this point.

INSTALLING THE HOUSING ASSEMBLY

11. Mount the housing assembly to the mounting bracket and
housing coupling. A safety cable is included with the housing to
temporarily hold it while wiring connections. Loop the safety
cable over one of the set screws on the housing coupling and
make the appropriate connections using the (2) screw-down
connectors supplied.

PRESSURIZING THE ENCLOSURE

Air is inserted in the enclosure through the Schraeder valve located
on the top of the unit. A pressure release valve is located under the
housing cap located in this same location. Air vents from the
pressure release valve between the housing top and the cap.

12. Undo the safety cable and twist the housing onto the
housing coupling. Secure all (3) set-screws provided on the
housing coupling (Figure 3).

13. Clean the outside of the dome with the text wipe

Before inserting air into the housing be sure the (2) cap
vents are free of obstructions such as ice or debris. (Fig 4)

Pressurized housings provide maximum protection for CCTV
cameras and lenses. The charge of dry nitrogen inside the housing
eliminates the effects of moisture, dust, insects and corrosive
exhaust fumes, allowing a longer life for your surveillance equipment.

To pressurize the housing, you must have the following:

1. A tank of dry nitrogen

2. A regulator on the tank

3. A hose with air chuck to connect the regulator to the housing’s
intake valve

Dry Nitrogen

Nitrogen is a readily available; check your local yellow pages for a
medical or industrial gas provider. If the tank is to be carried from
location to location, a size of 40 cubic foot is recommended. This
should be enough to refill 30 individual housings. Handle the tanks
with care. Although nitrogen is an inert gas, the tank is highly
pressurized and if the valve or regulator is damaged the tank could
be dangerous. Tanks of dry nitrogen can be kept for several years.

The Regulator

The tank will have a standard 580 fitting, but a regulator will be
required. A recommended regulator for the tank would be a Harris
#9296-15-580 or #425-15-580. For local distribution you can contact
Harris at 800-241-0804.

The Hose

The purge valve, called a “Schraeder” or “dill” valve, is similar to the
air intake valve on car or bicycle tires. To connect the regulator to
the purge valve on the housing, you’ll need a hose with a 1/4” barb
on one end and an air chuck on the other. The barb connects to the
regulator, the air chuck to the Schraeder valve. These hoses can be
obtained at local auto parts stores.

Pressurizing the Housing

Set the gauge on the regulator to between 5 and 10 psi. Place the
air chuck on the Schraeder valve, just as you would on a tire, and
press down to begin filling. Air should start venting from the pressure
release valve after a few minutes. Once you’ve completed filling the
housing, check the pressure with a pressure gauge. It should be 3 ­5 psi. When you have verified the pressure, reconnect the air chuck
and purge the housing for an additional two minutes.
