INSTALLATION FOR MMR TRANSMITTER

INTRODUCTION

This kit supplies the parts necessary to add the NightFighter Transmitter to the following SCBA:

•MMR without a Quick-Fill Option

•MMR with an old-style (pipe thread) Quick-Fill Option installed

•MMR with a Redundant Alarm installed

•MMR with an ICM 2000/2000 Plus installed

You must be a Certified Repairperson to perform the installation procedures which follow.

COMMON PARTS

•638166 O-ring

•635277 Backup ring (3)

•10003605 Spool

REQUIRED TOOLS

The tools contained in the Tool Kit supplied to Certified Repairpersons will be sufficient to

install this kit.

WARNING!

Before starting the procedures below, be sure that the cylinder valve is completely closed.

Be sure that nothing blocks the regulator outlet. Open the bypass valve to relieve any

pressure in the system. Failure to follow this precaution can cause serious personal injury

or death.

PREPARING AN MMR WITH NO QUICK-FILL OPTION INSTALLED

Note: If your SCBA does not have the Quick-Fill Option installed on the over-the-shoulder

gauge line hose, you must remove the gauge from the MMR harness gauge hose.

1. Close the bypass valve fully.

WARNING!

Do not disconnect the alarm coupling nut when pressure is shown on the harness gauge.

Always be sure that you have released all pressure from the regulator. Removing the

coupling nut with the regulator pressurized may result in serious personal injury or death.

2. Unscrew the alarm coupling nut from the cylinder valve.

hose fitting.

2. Using the O-ring removal tool, remove the O-ring and backup ring from the end of the hose

fitting. Discard the old O-ring and backup ring.

3. Go to Installing the Transmitter in the Adapter Block (below).

PREPARING AN MMR WITH AN OLD-STYLE (PIPE THREAD) QUICK-FILL

OPTION INSTALLED

1. Using wrenches, unthread and remove the existing Quick-Fill block and pressure gauge from

the gauge hose fitting.

2. Using the O-ring removal tool, remove the O-ring and backup ring from the end of the gauge

hose fitting.

Note: You can salvage the Quick-Fill Coupling from the exiting block.

3. Place the Adapter block in a vise. Use protective sleeves to keep from damaging the block.

Unthread the coupling from the block using a 1" deep-well socket. Set the adapter block

aside.

4. Remove and discard the existing O-ring (P/N 635068) from the Quick-Fill coupling (P/N

485070). Use a plastic pick, a tooth pick or a bull nose dental pick.

thin film of Christo-Lube to the P/N 635068 coupling O-ring. Slide the new O-ring over the

coupling threads. Remove the tape.

4. Thread the coupling into the block and tighten to 70-75 ft.-lbs. using a 1" deep-well socket.

INSTALLING THE TRANSMITTER ON THE GAUGE LINE

1. Apply a thin film of Christo-Lube to a newbackup ring. Place the backup ring in the groove

on the end of the hose fitting.

2. Apply a thin film of Christo-Lube lubricant to a newO-ring. Place the O-ring in the groove

on the end of the hose fitting.

3. Insert the hose fitting into the Transmitter Adapter Block. Torque the adapter to 50-60 in.-

lbs.

Note: If your apparatus is equipped with the Redundant Alarm or ICM, its pressure gauge will

have the Spool included. Make sure that the spool stays with the gauge.

•Check that the spool is present in the gauge (Redundant Alarm or ICM) outlet.

Note: If the spool is not installed, you must first install an O-ring and backup ring on each end,

•Apply a thin film of Christo-Lube lubricant to two P/N 635277 backup rings. Place one

backup ring in the groove on each end of the spool.

•Apply a thin film of Christo-Lube lubricant to two P/N 638167 O-rings. Place one O-ring in
