5.0 INSTALLATION
5.1 Important Safeguards1. Always use safety goggles when servicing
the unit.
2. Never use an unregulated gas supply topressurize the enclosure. The valve should beregulated with a maximum of 70 kPa (10 psi)output.
3. PRESSURIZE USING DRY NITROGEN ONLY!
5.2 Install Mount and Coupling
1. The standard model is designed as a pendantmount housing with a 1.5 in. NPT housingcoupling provided (to be used with a standard1.5 in. NPT pipe). Alternately, the housing canbe used with other brackets that are designedwith 1.5 in. male pipe threads.
2. Install the pendant pipe or wall mount bracketin the desired location. Be sure the bracket isproperly and securely mounted to a supportingstructure capable of rigidly holding the weightof the entire unit. (Refer to the instructionsprovided with the mount for completeinformation.)
3. Pipe threads should be clean and rust free.Although a hermetic connector protects theinside of the enclosure from all moisture, it isstill recommended that a thread sealer be usedon the threads of the housing coupling. Attachthe housing coupling to the bracket or pendantpipe (Figure 1).
5.3 Open the Housing1. Release any pressure that may have built up
during shipping by pressing down on theSchraeder valve to bleed off the excess pressure.
2. Open the housing by loosening the nine (9)captive screws located on the housing ring, nextto the lower clear dome. Be careful not to backthe screws all the way out. Twist the domeslightly in a counter-clockwise motion toremove it (Figure 2). Remove the protectivebarrier from the PRS-HOUSING and discard.
3. Be careful not to lose or damage the O-ring thatis in the groove of the housing. Care must betaken to avoid getting any dirt on this O-ring,since this could cause an incorrect seal when thehousing is re-assembled.
5.4 Calibrate HousingThe PRS-HOUSING features an internal low-pressuresensor alarm. Before installing the camera into the unit,the PRS-HOUSING must be calibrated to the localatmospheric pressure. The heater/blower/pressure sensorpower must be connected to do calibration. See Figure 4for wiring information. The procedure is as follows:
1. Apply POWER to the unit. The red LED will turn ON and remain constant.
2. After approximately 30 seconds, the LED willstart blinking. This indicates the unit is ready tobe calibrated.
3. Press the calibration switch located next to the redLED. When the switch is released, the LED willturn off which indicates the calibration hasoccurred and is permanently stored.
4. Turn the power OFF.
5. The unit is now ready to install the camera. SeeSection 5.6 Install Camera Module.

5.8 Pressurize the HousingDry nitrogen air is inserted in the enclosure throughthe Schraeder valve located on the top of the unit. Apressure release valve is located under the housing capfound in this same location. Air is vented from thepressure release valve between the housing top and the cap.
Pressurized housings provide maximum protection forCCTV cameras and lenses. The charge of dry nitrogeninside the housing eliminates the effects of moisture,dust, insects, and corrosive exhaust fumes, allowing alonger life for your surveillance equipment.
To pressurize the housing, you’ll need the following:
1. A tank of dry nitrogen
2. A regulator on the tank
3. A hose with an air chuck to connect theregulator to the housing’s intake valve
5.8.1 Dry NitrogenNitrogen is a readily available; check your local yellowpages for a medical or industrial gas provider. If thetank is to be carried from location to location, a size of1 cubic meter (40 cubic foot) is recommended. Thisshould be enough to refill 30 individual housings.Handle the tanks with care. Although nitrogen is aninert gas, the tank is highly pressurized and if the valveor regulator is damaged, the tank could be dangerous.Tanks of dry nitrogen can be kept for several years.
5.8.2 The RegulatorThe tank will have a standard 580 fitting, but aregulator will be required. Recommended regulatorsfor the tank are: Harris #9296-15-580 or #425-15-580.For local distribution you can contact Harris at 800-241-0804.
5.8.3 The HoseThe purge valve, called a "Schraeder" or "dill" valve, is similar to the air intake valve on car tires or bicycletires. To connect the regulator to the purge valve onthe housing, you’ll need a hose with a 1/4-inch barb on one end, and an air chuck on the other. The barbconnects to the regulator, and the air chuck connectsto the Schraeder valve. These hoses can be obtained atlocal auto parts stores.
5.8.4 Pressurizing the Housing1. Set the gauge on the regulator to between of
35 kPa (5 psi) and of 70 kPa (10 psi).
2. Place the air chuck on the Schraeder valve, justas you would on a tire, and press down to beginfilling.
3. Air should start venting from the pressurerelease valve after a few minutes. Once you’vecompleted filling the housing, check thepressure with a pressure gauge. It should bebetween 21 kPa (3 psi) and 35 kPa (5 psi).
4. After you have verified the pressure, reconnectthe air chuck and purge the housing for anadditional five (5) minutes.
Locate the internal humidity strip on thecamera bracket (easily visible with the bubble inplace), and ensure that it has changed from pinkto blue.
