This booklet with help you understand everything there is to know about D.J Safety / Motorsport Connections on-board fire systems. This can also be used as a training manual for technical inspectors so they can better understand how systems work and how to identify possible problems before they occur.

SERVICE AND MAINTENANCE Removal of the system from a race car can be carried out by any person. HOWEVER, there are some basic rules to follow. The bottle head is designed with a pressure release burst disc. This burst disc is what keeps pressure in the cylinder. It’s important to remember that nothing should be allowed to press against this disc as the bottle will discharge. If you are required to discharge bottle for any reason follow these steps:
• Remove bottle from vehicle, being careful not to rupture the burst disc positioned in the head of the bottle. • With the bottle standing in its upright position, inspect the gauge and record bottle pressure. This should be
in the green section, around 360psi. • Install a -04 hose on to the injector head and insure other open nipples are capped. • Push down on injector head. This will rupture burst disc and discharge bottle through the -04 line (point
away from your body). • Wait 2-3 minutes until bottle has completely emptied.
Note: If nothing happens when the injector head is depressed you must cap all hose nipples with Speedflow caps (820-04), tighten and send to a certified refill agent listed on the last page of this document.
MAINTENANCE SCHEDULE Maintaining the Cold Fire System is the purchasers, owners and operators responsibility. This section lists the minimum requirements for all Motorsport Connections (MSCN) Cold Fire on-board systems.
Refilling of the system must be carried out by accredited MSCN personnel only! Inspection, testing and servicing of all MSCN Cold Fire Bottles must be completed every 2 years. All bottles are stamped with a Fill/Inspection Date. A bottle dated outside this 2 year date is deemed illegal. For systems that operate in aggressive environments (such as Funny Car, Doorslammer or anything with intense vibrations), we strongly recommended a more frequent servicing interval by inspecting after every race meeting. Here is a simple 10 point check list to ensure your MSCN Cold Fire System is in operating condition. Please note: there is no way of knowing if the bottle siphon tube has been damaged due to a crash or severe tyre shake. If you have experienced any of these we recommend sending your bottle back for servicing.
1. Check that the injector head is clean, secure and undamaged. 2. Check that the bottle gauge is clean, undamaged and pressure is reading around 360psi. 3. Check that the nozzles and mounting brackets are clean (unblocked), secure and undamaged. 4. Check that the SFI labels are in place, visible, legible and bottle is in date with ANDRA specifications. 5. Check that the bottle and bottle mounting bracket are undamaged and secure. 6. Check all manual activation modules for corrosion and free movement of valve handle. 7. Check for free passage through all hoses and fittings by using dry nitrogen (or water). 8. Record the service on the attached service tag (and in logbook if required). 9. Check all -04 hose fittings are tight and leak free. 10. Check to make sure hoses are not cracked or broken.
Please note all components used with MSCN Cold Fire kits must be as per the system requirements. We do not allow different types of plumbing, nozzles or tee junctions to be used with the MSCN Cold Fire kits. Systems must be
plumbed with either -04 ¼” hard tubing made from either alloy or stainless tubing. We also allow the use of -04 stainless steel Teflon braided Hose. Plastic tube is not acceptable.
All Motorsport Connection (MSCN) Cold Fire bottles are serial numbered at the bottle head and on the injector head.
This number is recorded at all MSCN filling locations. At this time the bottle is assigned an SFI number and noted to
which class of racing it will be used for. This information allows motor racing sanctioning bodies complete
confidence that all racers are up to date with on-board systems. A simple bottle ID check is all that’s required to
identify bottles that have not been regularly serviced or are out of date.
Motorsport Connections are able to service and refill bottles to the SFI 17.1 standard within Australia.
All MSCN Cold Fire bottles must display the following numbers at the top of the bottle.
DOT-3AL 1000 EY0003556 CLIFF DIV 05 * 12 TC-3ALM 69 Bottles that do not display this number are unable to be serviced at any MSCN refill centre. The above bottle is the
correct size to carry 10lb of Cold Fire Agent.
SFI 17.1 STICKERS
Once the SFI sticker has been placed on the bottle it may not be removed.
SFI 17.1 stickers that have Sellotape placed over the top are deemed illegal.
Your SFI 17.1 sticker must match that of the bottle serial number. If it does not it is illegal.
Modification of bottle sticker will deem the bottle illegal. This includes removing manufacturer’s logo.
