PREPARING YOUR NEW EXTINGUISHER FOR USE
THIS MANUAL IS ATTACHED TO EVERY NEW EXTINGUISHER SHIPPED FROM THE FACTORY. IT
CONTAINS VALUABLE INFORMATION WHICH SHOULD BE STUDIED BY EVERYONE WHO WILL
USE OR SERVICE THE EXTINGUISHER. THE MANUAL SHOULD BE STORED IN A CONVENIENT
LOCATION FOR EASY REFERENCE.
1. Remove all wrappings, straps and pallet retaining bolts. There will be a small carton affixed to the
shipping pallet. Remove the carton and set it aside. Do Not Discard this as it includes 781 components.
2. Examine the extinguisher for shipping damage.
3. Check to insure that the hose connection to the operating valve and nozzle connection to the hose are
tight.
4. Check to insure that the discharge nozzle is in the CLOSED position. A ring (safety) pin should be
installed in the body of the discharge nozzle sealed with a tamper seal.
5. All Models 781 and 783 are shipped from the factory fully charged. Visually inspect the pressure gauge
– the pressure should be in the GREEN ZONE (240 +/- 15 psi range). The most accurate method to
determine if the extinguisher is filled with the proper amount of chemical is to weigh the unit. The gross
weight is indicated on the nameplate (label).
Note: Slight pressure variances in the gauge reading may be found if the extinguisher has been
subjected to extremes of heat or cold. High temperatures can cause high gauge readings and low
temperatures, low readings. When in doubt, condition the extinguisher to 70°F (21°C) for several
hours to obtain more accurate pressure gauge readings.
6. A carton containing the following items will be attached to the shipping pallet: #14-19272, #16-10147,
#17-09956, #18-18313, #20-10210, #21-10173, #25-04444, #28-10262, and #29-18751.
