7. Make certain that the locking pin has been installed in position (manual release lever should be parallel with nameplate). Then replace the nameplate to control head, tightening screws securely.
NOTE :
On three and four cylinder systems, one of the two automatic control heads must be a tandem type, identified by a nameplate on the circular diaphragm chamber. Make certain that such systems include one primary and one tandem control head.
DISCHARGE HEAD
CAUTION: To avoid the possibility of accidental discharge, do not install the discharge head until the automatic control head has been installed on the cylinder Valve and connected to the remote control cable.
1. Install the discharge head on the cylinder valve, positioning the head so that the discharge outlet is located conveniently for connecting to the supply piping or to the flexible discharge loop. Tighten the swivel mounting nut securely.
2. On one-cylinder installations, connect the supply piping to the outlet of discharge head. On two-or-more cylinder installations , connect the flexible discharge loops to the discharge heads and the "Y" fitting or manifold.
Installation -Accessory Equipment
REMOTE CONTROL PULL BOX
If a remote control pull box is to be installed, it may be located on a bulkhead outside the protected space, where it will be easily accessible and convenient at time of fire. It should be located in a safe area beyond the range of possible flames or smoke that may be escaping from the protected area.
1. Drill the necessary holes for installation. Then place the pull box body in position and fasten it with the mounting screw.
2. Assemble the large locknut to the rear of the pull box body and tighten securely. The pull handle, plastic shield and nameplate ring are not to be in stalled until the cable is run through the piping. See "Remote Control Piping and Cable."
3. If bulkhead is more than 1" thick, install a 3/8" nipple of sufficient length, anchoring it securely with a conduit washer and locknut as illustrated. If the control cable changes its direction at this point, a corner pulley must be installed.
4. After the cable is installed, and before connecting it to the control head, pull the cable back and forth several times to make certain that it is free.
5. When satisfied that the cable is properly installed, pull the cable from the control head end to seat the pull handle in the pull box; then connect it to the automatic control head. Install the plastic shield and nameplate ring. For connection of the cable to the control head, see "Automatic Control Head."
REMOTE CONTROL PIPING AND CABLE
All remote control cable must be enclosed in pipe or conduit. This should be standard 3/8" hot-dipped galvanized steel or standard weight brass. Couplings should be of the same material as the piping.
All pipe must be reamed after cutting to remove any burrs which would tend to fray or seize the control cable. Kidde corner pulleys are to be used at all changes in direction. No bends or offsets in the piping are permitted; this is important.
A corrosion-proof 1/16" dia. cable is furnished with remote control systems. The cable must be continuous from the pull box to the control head; do not tie or splice cable.
1. Run the piping from the pull box to the cylinder location as directly as possible, using corner pulleys at all changes in direction. Support the piping firmly, especially at the corner pulleys.
2. Thread the cable into the pull handle fastener as shown on the tag which accompanies the pull box. The short end of the cable should project about 1/2" from the fastener. Screw the fastener into the pull handle socket.
3. Feed the free end of the cable into the pull box and through the piping. Remove the cover and wheel from each corner pulley to facilitate feeding of cable through pipe.
4. Replace the corner pulley wheels and covers, making certain that the cable sets properly 'in the groove of each wheel before installing the cover.
5. Work the cable back and forth several times to make certain that it operates freely, then connect the cable to the automatic control head. To make this connection, see "Automatic Control Head."
DUAL PULL MECHANISM
This equipment is used where two remote controls are to be installed. The single outlet leads to the control head; the double outlet leads to the remote control pull boxes. When installing the unit, make certain that the
