START-UP/INSPECTION TEST PROCEDURE
NOTE: This service procedure covers a single manifold system however a duplicate manifold and tank
setup is possible. If you have a two manifold system, a second service kit will be required along with
fittings to connect it properly. Refer to Table 23 on page 77 for service parts.
Required Tools:
• Precision Slotted Screwdriver
• Heat Gun
• Nitrogen Service Kit - single manifold only
• Balloons
• Warm Soapy Water
• 1/4" SAE Tee Connector with cap and valve core. 1/4" female knurl and 1/4" SAE male connections. Used for
multiple manifold systems only.
• Micro Leak Detector
• In-Line Filter
• Digital Pressure Gauge
CAUTION!: Never use magnetic tools or cause excessive vibration when the actuators are bolted to the
cylinder(s).
Parts:
• Supervised Loop Wiring: Black Wire - Part #: 441601C6.FE0 & White Wire - Part #: 441601C6.FE9
• Pull Station Wiring: Belden Wire - Part #: 6320UL (or similar)
• WAGO connectors - Part #: 221-412
• Replacement PAK O-rings
Fire System Wiring Connections
• Connect the Manual Activation Device (MAD) using Belden #6320UL, 18 Gauge plenum rated wire.
• Connect all Firestats using Belden #6320UL (or similar), 18 Gauge plenum high temperature rated wire. Single
hood systems with a hood mounted utility cabinet may not have any additional stats.
• The supervised loop must be run through metallic conduit. Do not run wiring with high voltage
wires. Verify all supervised loop wires are free from damage/stress. All supervised loop wires must be termi-
nated in terminal blocks, junction boxes, and push-stations.
• Install the 24V DC or 120V AC gas valve.
• Verify that all solenoid wires and electrical control panel wiring are secured. Any supervised loop wiring within
18 inches of the top of the hood must be high-temp wire, type MG or MGT with WAGO connectors (Part # 221-
412). Type MG White (Part # 441601C6. FE0), Type MG Black (Part # 441601C6.FE9).
Preparing System for Test
• Place all building alarm systems in test mode. Place the electric control panel in “Test” mode. Refer to
Figure 51. Verify there are no supervision faults on the HMI.
• Verify that the hood, duct, and kitchen appliances have not changed (including type, dimensions, and location)
from the approved design. Appliance drops must be between 35-50 inches from the hazard surface.
• Verify that all cylinder discharge outlets are connected to the system.
• Verify that all cylinders are secured in their bracket(s).
• Verify that a valve cap or supervisory pressure switch (optional) is installed on each secondary cylinder
Schrader valve.
• Verify that nozzle caps are installed.
NOTE: If this is the first service after installation, the PAK hose should be disconnected, and the primary
and secondary valve actuators should be in the ship/test position. Refer to Figure 52 on page 60.
