6. Aim the nozzles to a pre-determined aim point in accor-
dance with the instructions in the “System Design” section.
Using the Nozzle Aiming Device will aid in the aiming
process. The device clamps to the nozzle and emits a small
laser light that reflects on the surface where it is aiming. If
the nozzle is used with a Swivel Adapter, the nozzle with the
Aiming Device can be rotated to the exact aiming point and
then tightened to hold that angle.
7. Before installing blow-off caps on nozzles, apply a small
amount of Dow Corning No. 111 silicone grease across the
opening in the nozzle tip. Also apply a small amount to coat
the exterior of the blow-off cap. DO NOT FORCE SILICONE
GREASE INTO NOZZLE TIP OPENING OR FILL CAP
WITH GREASE.
NOTICE
When using old style metal blow-off cap
with spring clips, make certain the spring
clip rotates freely on the metal cap and
coat the outside of the cap, including the
clip, with Dow Corning No. 111 silicone
grease.
8. Make certain a blow-off cap is in place over each nozzle
tip. These blow-off caps are designed to keep grease from
building-up on the nozzle orifice and inhibiting the agent
flow. See Figure 5-8.

INSTALLING THE AGENT DISTRIBUTION HOSE
(FOR CASTERED/MOVEABLE EQUIPMENT)
Agent Distribution Hose can be used in the supply line or appli-
ance branch line to allow a castered cooking appliance with
castered supports with nozzles attached directly to the appliance,
to be moved out of its normal operating position for service or
cleaning.
CAUTION
The following instructions must be followed in their entirety.
Failure to do so may result in the R-102 Fire Suppression
System not functioning properly due to incorrect installation.
CRITICAL INSTALLATION REQUIREMENTS
1. Design and installation must be performed by qualified
personnel.
2. The Agent Distribution Hose shall not be concealed within
or run through any wall, floor, or partition, and shall not have
any direct exposure to excessive heat or radiant flame from
the cooking appliances.
3. Strong cleaning solutions or chemical substances must not
come in contact with the Agent Distribution Hose. These
may include acids, solvents, fluxes with zinc chloride, or
other chlorinated chemicals. In case of contact, rinse down
the Agent Distribution Hose with water and dry thoroughly.
4. Contact with foreign objects, sharp edges, wiring, or
substances must be avoided.
5. Bending and flexing of Agent Distribution Hose on move-
able appliances (i.e. those factory equipped with casters)
should be limited to pulling and pushing the appliances in
or out for cleaning or maintenance. The hose shall never
be installed or bent tighter than a 3 in. (76 mm) radius (6 in.
(152 mm) diameter) loop.
6. The Agent Distribution Hose must not be kinked, twisted,
or have sharp bends when installed or when equipment is
pulled away from the wall.
7. Make sure that all fittings are tightened properly.
8. Adequate means must be provided to limit the movement
of castered appliances. A 36 in. (914 mm) long Restraining
Cable supplied with the agent distribution hose is required
to be used for all castered appliances using the Agent
Distribution Hose. (Refer to Restraining Cable Installation
Instructions.)
9. The Restraining Cable requires periodic maintenance to
ensure proper operation.
10. The Restraining Cable must be attached to the wall and
appliance anytime the distribution hose is connected to the
appliance.
11. Do not over-extend the Agent Distribution Hose when
moving equipment (for cleaning, maintenance, etc.).
AGENT DISTRIBUTION HOSE INSTALLATION
INSTRUCTIONS
Before proceeding, CAREFULLY read all instructions, including
all CRITICAL INSTALLATION REQUIREMENTS.
General Requirements
1. The Agent Distribution Hose (which is part of the Discharge
Hose and Restraining Cable Kit), is 0.5 in. (13 mm) diameter
