CONSEP
Condenser / Separator
Installation, Maintenance
and Inspection
General
The Haldex CONSEP, Figure #1, is designed to condense, separate and
expel the majority of the oil and water before reaching the air dryer. The
contaminants accumulate in the sump area of the CONSEP. An integral part
of the CONSEP unit is the Haldex Automatic Drain Valve; Figure #2. The
contaminants are automatically drained upon each brake application.
Installation
The CONSEP must be mounted in the air line between the compressor and
the air dryer. It must be mounted as close as possible to the air dryer; if
equipped. The CONSEP inlet temperature should not exceed 150°F. This
can normally be achieved with at 12' compressor discharge line. For severe
service it may be necessary to add a portion of metal piping to achieve the
150°F inlet.
1. Block tires to prevent vehicle from rolling. Release all air from the
air system.
2. Using the "H" mounting bracket as a template, mark the mounting hole
locations on a suitable plate or frame member and drill 3/8" dia. holes for
5/16" bolts. Assemble the "H" mounting bracket and bolts, (see Figure #4)
then mount CONSEP with the enclosed lock nuts and torque to 20 ft. lbs.
Damage will occur if over torqued.
3. The compressor discharge line is connected to the side inlet port of the
CONSEP (1/2" - 14 NPTF). The top outlet port is connected to the air
dryer; Figure #1.
4. Electrical Connections. See Figure #4. Mount the relay in a water
protected area. With spade connectors and 14-16 gauge wire, connect
terminal #86 on the relay to a chassis ground. Connect terminal #30 to an
ignition switched circuit. Locate the existing brake light switch. Determine
which terminal on the switch is "hot" when the brakes are applied and
connect to terminal #85. From terminal #87a (heated mode) route a wire
to the automatic drain valve. If vehicle is operating in an area where air
system freezing is not a concern, use terminal #87 (unheated).
5. The pigtail connector at the drain valve is equipped with either a "Packard
Weather-Pack", "Metri-Pack" or sealed butt connector; see Figure #4.

Maintenance
The CONSEP must be inspected periodically for proper operation. The
interval between inspections is determined by the type of service. High
compressor duty cycles and high temperatures can cause a buildup of
carbon in the condenser, drain valve and filter. This contamination must
be removed for proper operation.
Recommended Service Intervals
24 months....Light Duty, Over-The-Road Tractor Trailer Operation
12 months....Medium Duty, City Delivery
6 months......Heavy Duty, Refuse Service, City Transit
Inspection
1. Check connections at CONSEP for air leaks during the compressor
loading cycle by applying soap solution around pipe fittings Check
bottom of drain valve for air leaks around manual drain port.
2. With ignition switch on and compressor pumping, apply brakes and
release. After each brake application and release, an audible "click"
will be heard at the drain valve and a slight puff of air will be expelled.
If valve does not operate, check electrical wiring for correct voltage
(brakes applied). Insure that the voltage matches the voltage mentioned
on the drain valve label. If there is no current, check the electrical circuit
at Haldex relay and brake light switch. If electrical circuit is OK and the
valve does not discharge, the unit must be serviced.
