ately marked or necessary information furnished. If this has not been done, it is important that we be notified of the volume of each space at so that the proper recommendations once can be made. Each space protected must be provided with at least one heat actuator.
If it is desired to operate the system manually from two remote locations, in addition to the control of the cylinder, an extra pull box, and a multiple pull mechanism can be supplied.
CYLINDERS
1. Care should be taken in the selection of the location and mounting of the cylinders. The temperature of their location must also be considered. The safe storage temperature for all cylinders up to and including 35 lb. capacity is 140oF. (60oC.), for cylinders of 50 lb. capacity and over, 150oF. (65oC.)
2. The cylinders of systems having a remote manual control handle may be installed anywhere. On local control systems (manual release at control cylinder), the cylinder must be installed OUTSIDE the space(s) protected and must be easily accessible for operation at time of fire.
3. All cylinders may be mounted in a vertical position or inclined within the range B-D as shown on Figure l2. Only systems of 100 lbs. or less, can be mounted less than 30o from horizontal, as shown in the shaded area A-B and D-E. If mounted in this area, the instruction plate on the cylinder valve body MUST FACE UP. This is done to permit the bent siphon tube, within the cylinder, to point down into the liquid carbon dioxide, which is necessary for the proper operation of the system. The instruction plate may face in any direction when the cylinder is mounted more than 30o above the horizontal (within the range B-C-D). No cylinder should be mounted at less than 10o from the horizontal as shown in the dark portion in Figure 12.
4. Weigh the cylinder to determine if its content is fully up to charge. Empty and full weight of cylinder is stamped on cylinder valve body,
5. Mount cylinder racks as shown on Figures 11, 15, & 16.
6. Place cylinders in racks and position control cylinders so that control head outlet is in the desired position. Then tighten racks securely.
FINAL PROCEDURE
1. On local manual control systems, mount the small nameplate shown in Figure 11 near the supply cylinder (s).
2. Review the entire installation and make certain that all equipment has been installed in accordance with these instructions.
3. The miscellaneous parts furnished with the system should be stored away where they will be available when the system is being inspected or cylinder recharged.
4. It is recommended that the Application for Certificate of Installation (Form 40086) be filled out immediately upon completion of the installation and sent to Waiter Kidde & Company, Inc., 675 Main Street, Belleville, New Jersey, attention of the Marine Department. This will permit us to review the installation and will also facilitate subsequent application for reduction in insurance rates.
Testing of the Kidde Automatic System
A. Test Pneumatic Control Head
1. Make certain sufficient clearance is provided at mounting nut so that control head will not be damaged upon operation.
2. If control head has been operated, reset by placing screwdriver in
stem as shown in Figures 2 & 3, set turning clockwise until stem locks in position (with arrow on reset seem lined up with "set" arrow on nameplate).
NOTE: Slight resistance will be met just before stem locks.
3. Procure the manometer test set* and pour water into the open tube until the water level in both tubes is exactly at the zero mark.
4. Connect the test fitting "A" of the manometer test set to the diaphragm chamber of the valve.
5. Close off the rubber tube "B" by squeezing tightly with the fingers, and then apply pressure by very gradually squeezing the rubber bulb "C". The valve should trip on a pressure of from 4-1/2 to 7 inches of water. This pressure is the actual height, in inches, between the water levels in the two tubes, and is equal to twice the reading of either tube. After the pneumatic control head has operated, be sure to release the rubber tube "B" first, and then allow the rubber bulb "C" to expand gradually; otherwise, the water will be sucked up into the tubing and control head. Disconnect the manometer test set from the diaphragm. Reset control head by turning reset stem to its Set position.
*Not furnished as part of system.
B. Test Actuating System
The heat actuator and the actuator tubing must be tested for leakage. To do this, proceed as follows:
CAUTION: When using the manometer test set, extreme care must be
taken not to allow any water to get into the rubber bulb
or into any of the parts being tested.
1. Pour water into the open tube of the manometer test set until water level in both tubes is exactly at the zero mark.
2. Make up test fitting "A" on manometer to the actuator tubing at pneumatic control head connector nut.
3. Gently squeeze the rubber bulb "C" about half-way and then close off the rubber tube "B" by pinching with the fingers. Very gradually, release the rubber bulb to its normal shape. This will cause the water level in the two tubes to change.
4. If all connections are absolutely tight, the water level will remain in the position taken in item 3 and will not change as long as tube "B" is held closed. Observe the level of the water for at least one minute and then release tube "B". It is absolutely essential that the water level remain the same as long as tube "B" is held closed. Even the very slightest falling of the water leg is serious, for it indicates a leak which may prevent the automatic operation of the system at time of fire. Disconnect test set from actuator tubing.
GENERAL MAINTENANCE
The Kidde System as installed requires no more than ordinary care to insure it's proper operation at all times. Frequent inspections should be made, however, as experience has shown that emergency equipment of this kind is often unintentionally neglected or tampered with.
ONCE EVERY MONTH
Make a general inspection of the entire system to make certain that nothing has been placed to interfere with the operation of the equipment or with access to the release controls. Inspect all piping and equipment for mechanical breakage. Replace any damaged equipment immediately.
ONCE EVERY SIX MONTHS
Test the actuator system and control bead as described under "Testing, Maintenance & Recharging,"
ONCE EVERY YEAR
It is recommended that the system be inspected by an experienced service representative of Walter Kidde & Company, Inc.
The Kidde cylinder should be removed and weighed to determine the (Continued on page 235)
