AFTER A DISCHARGE
IN THE EVENT A FIRE SHOULD OCCUR AFTER
THE GUARDIAN G600-B SYSTEM HAS BEEN
INSTALLED
AND
EXTINGUISHED
A
FIRE,
PROCEED AS FOLLOWS:
CLEAN UP
CAUTION: WHEN CLEANING THE KITCHEN
RANGE HOOD OR WHEN YOUR GUARDIAN G600-
B SYSTEM IS REMOVED, THE SAFETY PIN MUST
BE REINSERTED INTO THE FIRE EXTINGUISHER
VALVE ASSEMBLY.
After the system has discharged, be sure to disconnect all
electrical power to the range top appliance and turn the gas
off, in the case of a gas range top.
Breaker to range should
be turned off before servicing
. Use rubber/latex type
gloves to protect skin and safety glasses for eye protection.
Use a sponge and warm soapy water to wipe off excess
chemical. A damp cloth should be used in the final cleaning
process to remove all residual extinguishing agent. It is
critical to be thorough as any residual agent remaining is
capable of causing damage. Do not use a water vacuum
type cleaner.
NOTE: Before replacing the liquid chemical agent,
the extinguisher cylinder, valve assembly, valve
piping adapter, distribution assembly, hoses and
nozzles must be thoroughly cleaned by flushing
with water
and thoroughly dried. Wear proper eye
protection
and rubber or latex type gloves when
cleaning parts.
A complete system inspection and servicing must be
accomplished
immediately
following a system discharge.
Consult an authorized fire equipment company for service or
proper procedure.
RECHARGE
I
REACTIVATION OF SYSTEM
CAUTION: Before replacing the fire suppressant
agent, the extinguisher cylinder, release valve
assembly,
or
other
system
components,
appropriate eye protection and rubber or latex
type gloves must be worn.
1.
Make sure the breaker to the stove and hood is
turned off before servicing.
2.
Remove the 9V DC battery from the CPU board.
3.
Disconnect heat sensor 1 & 2 connections from the
Main CPU board and remove the heat sensors from
underneath the range hood/ microwave hood. Clean
sensors thoroughly with soapy water, rinse with clean
water. Blow off with clean dry air then set aside and
allow to fully dry. After a fire the sensor assembly must
be replaced. (P/N G605-A)
NOTE: Make sure the pressure gauge indicator
needle is in the "Recharge" area of the gauge face
and that the internal pressure of the agent
cylinder has been completely expelled and the
pull-pin is re-installed in the handle prior to
disconnecting the quick connect.
4.
Disconnect the quick connect below the handle and
remove the distribution assembly from underneath the
microwave hood / range hood.
5.
Thoroughly flush the distribution assembly with water to
remove any residual fire suppressant. Inspect
distribution assembly (hoses, fittings, nozzles) for leaks
or other damage and wipe dry with a clean cloth. Blow
clean dry air through the assembly then set aside and
let completely dry.
NOTE:
If leaks or other damage is found in the
distribution assembly, do not reinstall distribution
assembly until those parts, which are leaking or
damaged, have been replaced. See Parts List,
Page 21, if required.
6.
Disconnect
extinguisher
cylinder
release
valve
connections from the CPU board (See
FIGURE 2 & 3
,
Pages 4-5).
7.
Disconnect spring from the extinguisher handle.
8.
Remove the extinguisher cylinder assembly from the
mounting base by loosening the cylinder band.
9.
Unscrew and remove the extinguisher cylinder valve
head
I
siphon tube assembly from the extinguisher
cylinder. Rinse and thoroughly flush with water to
remove all residual fire suppressant.
10. Pour out any residual fire suppressant, which may be
left in the extinguisher cylinder.
11. Refill extinguisher cylinder with 4.9 Ibs. (54 oz.) of wet
chemical agent (Part #G-BRK) fire suppressant.
12. Replace the extinguisher cylinder valve head O-ring,
valve stem and spring. Reinstall valve head/siphon tube
assembly into the extinguisher cylinder. Do not combine
I
mix new and old chemicals or suppressants.
CAUTION: Do not use the extinguisher cylinder
gauge to determine when the intended charge
pressure has been reached.
A separate laboratory
gauge mounted in-line with the nitrogen supply
line is to be used to determine the agent cylinder
pressure. The target cylinder pressure of 100 psi.
(at 70 deg. F) should vary to compensate for
ambient temperature when pressurizing the
cylinder. (See the pressure/temperature graph in
Fig. 28,
page 19
)
13. Connect a nitrogen supply line to the 1/8” male quick
connect fitting and pressurize to the appropriate
pressure. (See
Figure 28
, page 19)
14. Reinstall the extinguisher cylinder assembly in the
enclosure base.
15. Refer to initial Installation

Arming the system
I
activation instructions to complete reinstallation
I
reactivation of the system. (See
FIGURES 3, 5, 7, 8, 9
,
