PRE-INSTALLATION WARNINGS
IMPORTANT:
It is extremely important that the original equipment manufacturers
specifications are followed when installing a new valve. Refer to vehicle and
suspension manufacturers instructions for location of the valve. Stop engine when working
under a vehicle. Always block the vehicle wheels to prevent a fore or aft roll. Bleeding off
system air pressure may cause the vehicle to roll. Keep hands away from brake chamber
push rods and brake adjusters; they may apply as
system pressure drops. Never exceed recommended working air pressure and always wear
safety glasses when working with air pressure. Never look directly into component ports or
direct a pressurized air flow at anyone. Never attempt to disassemble a component until you
have read and understood all recommended procedures. Some components contain power-
ful springs and injury can result if not properly disassembled. use only proper tools and
observe all precautions
pertaining to the use of those tools.
CAUTION:
Prior to disconnecting or connecting any airlines or valves, bleed off all air
pressure from the air supply system. Failure to do so can result in severe injury.
DO NOT
install a single height control valve of any type if the suspension or
vehicle manufacturer specifies a two (2) height control valve system.
DO NOT
use a time delay valve with a EGP valve on the same vehicle.
DO NOT
use antifreeze or other solvents in air supply line. Use of solvents or antifreeze
can damage seals and void the valve warranty.
ALWAYS
use a Pressure Protection Valve (PPV) and filter such as Haldex 90554107.
Attach PPV directly to the air reservoir for supply to the EGP.
