OPERATIONAL INSTRUCTIONS
OPERATOR SAFETY EQUIPMENT
•Blast operators and others working in the vicinity of
abrasive blasting must always wear properly-
maintained, NIOSH-approved, respiratory protection
appropriate for the job site hazards.
•DO NOT USE abrasives containing more than one
percent crystalline (free) silica. Ref. NIOSH Alert
#92-102
•Inhalation of toxic dust (crystalline silica, asbestos,
lead paint and other toxins) can lead to serious or
fatal disease (silicosis, asbestosis, lead or other
poisoning).
•ALWAYS wear NIOSH-approved supplied-air respirators
as required by OSHA, in the presence of any dust including,
but not limited to, handling or loading abrasive; blasting or
working in the vicinity of blast jobs; and cleanup of expended
abrasive. Prior to removing respirator, an air monitoring
WARNING
WARNING
I

PREFACE
instrument should be used to determine when surrounding
atmosphere is clear of dust and safe to breathe.
•NIOSH-approved, supplied-air respirators are to be worn
ONLY in atmospheres:
• NOT IMMEDIATELY dangerous to life or health and,
• from which a user can escape WITHOUT using the
respirator.
•Clemco supplied-air respirators DO NOT REMOVE OR
PROTECT AGAINST CARBON MONOXIDE (CO) OR ANY
OTHER TOXIC GAS. Carbon monoxide and toxic gas removal
and/or monitoring device must be used in conjunction with
respirator to insure safe breathing air.
•Air supplied to respirator MUST BE AT LEAST GRADE D
QUALITY as described in Compressed Gas Association
Commodity Specification G-7.1, and as specified by OSHA
Regulation 1910.139 (d).
•ALWAYS locate compressors to prevent contaminated air
(such as CO from engine exhaust) from entering the air intake
system. A suitable in-line air purifying sorbent bed and filter or
CO Monitor should be installed to assure breathing air quality.
•ALWAYS use a NIOSH-approved breathing air hose to
connect an appropriate air filter to the respirator. Use of a non-
approved air hose can subject the operator to illness caused
by the release of chemical agents used in the manufacture of
non-approved breathing air hose.
•ALWAYS check to make sure air filter and respirator
system hoses are NOT CONNECTED to in-plant lines that
contain nitrogen, acetylene or any other non-breathable gas.
NEVER use oxygen with air line respirators. NEVER modify air
line connections to accommodate air filter/respirator breathing
hose WITHOUT FIRST testing content of the air line. FAILURE
TO TEST THE AIR LINE MAY RESULT IN DEATH TO THE
RESPIRATOR USER.
•Respirator lenses are designed to protect against
rebounding abrasive. They do not protect against flying
objects, glare, liquids, radiation or high speed heavy materials.
Substitute lenses from sources other than the original
respirator manufacturer will void NIOSH-approval of this
respirator.
BLAST MACHINES AND REMOTE CONTROLS
•ALWAYS equip abrasive blast machines with
remote controls.
•Abrasive blast machine operators must wear NIOSH-
approved supplied-air respirators (ref: OSHA
regulations 1910.94, 1910.132, 1910.139 and
1910.244).
•NEVER modify OR substitute remote control parts. Parts
from different manufacturers are NOT compatible with Clemco
equipment. If controls are altered, involuntary activation, which
may cause serious injury, can occur.
•Inspect the air control orifice DAILY for cleanliness.
NEVER use welding hose in place of twinline control hose. The
internal diameter and rubber composition are UNSAFE for
remote control use.
•UNLESS OTHERWISE SPECIFIED, maximum working
pressure of blast machines and related components MUST
NOT exceed National Board approved 125 psig (8.5 BAR).
•NEVER weld on blast machine. Welding may affect
dimensional integrity of steel wall and WILL VOID National
Board approval.
•Point nozzle ONLY at structure being blasted. High
velocity abrasive particles WILL inflict serious injury. Keep
unprotected workers OUT of blast area.
•NEVER attempt to manually move blast machine when it
contains abrasive. EMPTY machines, up to 6 cu. ft.(270kg)
capacity, are designed to be moved:
• on flat, smooth surfaces by AT LEAST two people;
• with the Clemco "Mule"; or
• with other specially designed machine moving devices.
•Larger empty blast machines or ANY blast machine
containing abrasive MUST be transported by mechanical lifting
equipment.
AIR HOSE, BLAST HOSE, COUPLINGS, AND NOZZLE HOLDERS
•Air hose, air hose fittings and connectors at compressors
and blast machines MUST be FOUR times the size of the
nozzle orifice. Air hose lengths MUST be kept as short as
possible AND in a straight line. Inspect DAILY and repair
leakage IMMEDIATELY.
•Blast hose inside diameter MUST be THREE to FOUR
times the size of the nozzle orifice. AVOID sharp bends that
wear out hose rapidly. Use SHORTEST hose lengths possible
to reduce pressure loss. Check blast hose DAILY for soft
spots. Repair or replace IMMEDIATELY.
•ALWAYS cut loose hose ends square when installing hose
couplings and nozzle holders to allow uniform fit of hose to
coupling shoulder. NEVER install couplings or nozzle holders
that DO NOT provide a TIGHT fit on hose. ALWAYS use
manufacturers recommended coupling screws.
•Replace coupling gaskets FREQUENTLY to prevent
leakage. Abrasive leakage can result in dangerous coupling
failure. ALL gaskets MUST be checked SEVERAL times during
a working day for wear, distortion and softness.
•Install safety pins at EVERY coupling connection to
prevent accidental disengagement during hose movement.
•ALWAYS attach safety cables at ALL air hose AND blast
hose coupling connections. Cables relieve tension on hose and
control whipping action in the event of a coupling blow-out.

2.1.2 Limiting characteristics of Grade D air, as of the
publication of this manual is as follows:
Carbon Dioxide .................... maximum of 1000 ppm
Carbon Monoxide .................... maximum of 10 ppm
Odor ........................................ *No pronounced odor
Oil (hydrocarbons) ...................maximum of 5 mg/m3
Oxygen ...................................between 19.5 - 23.5%
* Specific measurement of odor in gaseous air is
impractical. Air may have a slight odor but the presence
of a pronounced odor renders the air unsatisfactory.
2.1.3 Special care must be taken to avoid accidental
connection to any lines other than compressed air; such
as, oxygen, acetylene, or nitrogen.
2.1.4 When the climate control tube is used for
breathing air, the quality of air supplied to the climate
control tube is extremely critical to the safety of the user.
2.1.5 Any air ingested from the climate control tube
must meet the requirement for respirable air as stated
herein. If the climate control tube supplies air to a vest
that is used with a hooded respirator, air supplied to the
vest must also be respirable air meeting the
requirements for Grade D or better.
2.1.6 Prior to using the respirator, read the owner’s
manual and all instructions, labels, and warnings relating
to the compressed air source. Take special care to abide
by all warnings from the compressor manufacturer
regarding compressor use, and from the cylinder and air
supplier, for breathing air cylinders and their use.
2.1.7 A Clemco CPF filter may be installed and
regularly maintained to remove objectionable odors, oil
mist, water, pipe scale, and other particulate matter.
2.2 Breathing-Air from Cylinders
DANGER
Operators must never use or operate breathing
air cylinders, without proper pressure reducing
devices, and training on their use. Breathing
cylinders are under extremely high air pressure.
Improper use could cause cylinders or
accessories to rupture, resulting in severe
injury or death.
2.2.1 Using cylinders (high-pressure air bottles)
requires special knowledge of their use and compliance
with OSHA Regulations. Refer to 29 CFR 1910.134(h)
and (i) and 49 CFR part 173, and part 178.
2.2.2 The employer shall ensure that cylinders used to
supply breathing air to respirators meet all requirements
which may include, but are not limited to, their testing
and maintenance, a certificate of analysis for air quality
and moisture.
2.2.3 Cylinders must be equipped with a properly
maintained pressure-reducing valve that reduces
pressure to the approved pressure range as shown in
Section 2.4.3.
2.3 Breathing-Air from Compressors
2.3.1 The employer shall ensure that air from
compressors used to supply breathing air to respirators
meets the requirements in 29 CFR 1910.134.(i)(5).
2.3.2 Precautions must be taken to prevent
contaminants from entering through the compressor
intake: Ref. 29 CFR 1910.134.(i)(5)(i). The compressor
inlet must be located away from all sources of toxic
contaminants including carbon monoxide, which is found
in engine exhaust (including the exhaust from the
compressor’s engine), and in any form of combustion.
No vehicles should be allowed near the compressor
intake. Contaminants can enter respiratory equipment
through the compressor air inlet. This inlet must not be
located near any exhaust system outlet, ventilation flue,
or source of fumes or particles of any kind.
2.3.3 The compressed-air supply system must be
equipped with suitable in-line air-purifying sorbent beds
and filters, and be maintained to further ensure
breathing air quality: 29 CFR 1910.134 (iii).
2.3.4 If the breathing-air supply is from a non-oil-
lubricated compressor, the employer shall ensure that
the carbon monoxide levels in the breathing air do not
exceed 10 ppm: 29 CFR 1910.134 (i)(6).
2.3.5 If an oil-lubricated compressor is used, the
employer shall use a high-temperature alarm or carbon
monoxide (CO) alarm, or both, to monitor carbon
monoxide levels. If only high-temperature alarms are
used, the air supply shall be monitored at intervals
sufficient to prevent carbon monoxide in the breathing
air from exceeding 10 ppm: 29 CFR 1910.134 (i)(7).
2.4 Operating Pressure
2.4.1 Air pressure at the point of attachment (the point
of attachment is where the respirator supply hose is
connected to the respirable air source) must be
maintained at pressures between 90 to 100 psi (pounds
per square inch), as shown in the table in Section 2.4.3.
Maintaining the correct operating pressure at the point of
attachment ensures the correct air flow to the respirator.

CCT CLIMATE CONTROL TUBE Page 4
© 2007 CLEMCO INDUSTRIES CORP. •www.clemcoindustries.com •Manual No. 08850
2.4.2 The Clemco CPF Inline Particulate Filter with
regulator meets this requirement for a regulator and
gauge, provided inlet pressure does not exceed 150 psi.
DANGER
Do not connect the climate control tube, CPF
Filter, or any other regulator or filter, to bottled
air that does not have a pressure reducing
valve that reduces pressure to the maximum
operating pressure of the respirator of filter it
services. Failure to comply with this warning
will cause devices rated at lower pressures to
rupture under the high pressure of bottled air,
which could cause severe injury or death.
2.4.3 Use the following table to determine the
minimum pressure setting and maximum respirator hose
length that may be used with the climate control tube.
Adjust the pressure with the respirator hose and
respirator attached. If the regulator is adjusted with static
pressure (no air flow), pressure may drop below the
required pressure when the respirator is connected, and
may result in low air flow. Setting the pressure as shown
provides a minimum of 7 cfm (cubic feet per minute) to
the respirator. The maximum allowable pressure for use

The maximum overall hose length used with the climate
control tube is 200 feet when providing air to a respirator.
2.5 Dew Point
2.5.1 If exhaust air reaches temperatures at or below
freezing, excess water vapor could freeze and cause the
air tube to ice-up. Compressed air should have excess
water vapor removed to attain a dew point below the
minimum anticipated temperature of the exhausting air.
Contact a compressed-air dryer distributor for dryer
recommendations.
2.6 Air Volume
2.6.1 The climate control tube must be supplied with
20 cfm of Grade D breathing air at 90 to 100 psi.
WARNING
The compressor must provide adequate output
and the plumbing between the compressor and
the point of attaching the respirator hose must
have sufficient capacity to supply the volume of
air at the pressure required. Restricted air flow
will cause discomfort to the user, and may
result in ingress of hazardous and toxic dust,
subjecting the user to health and life
threatening toxic poisoning and long term
respiratory disease and death.
3.0 SET-UP and ADJUSTMENTS
3.1 Attach Breathing Tube Assembly
CAUTION
Note the directional flow arrows on the labels at
both ends of the breathing tube. The flow
arrows indicate the direction of air flow to the
helmet. Flow arrows must point toward the
helmet. Failure to properly attach the breathing
tube may damage the tube's acoustical foam,
which will block air flow, or it may increase
noise levels beyond OSHA limits.
3.1.1 The breathing tube has a clamped-on end and a
molded-on end. Attach the molded-on swivel connector
to the climate control tube’s outlet as shown in Figure 2.
Figure 2
3.1.2 Attach the clamped-on end to the threaded air
inlet fitting at the back of the helmet as shown in Figure
2. Do not over-tighten; hand-tight is sufficient.

3.2 Air Supply and Pressure
3.2.1 Initiate the air supply and regulate air pressure
between 90 and 100 psi, as shown in Section 2.4.3.
3.3 After donning the respirator, securely attach the
belt and climate control tube around the waist. Adjust the
belt size as required.
3.4 Adjust Air Temperature
3.4.1 To adjust air temperature, move the temperature
control lever (shown in Figure 3) fully toward the right,
lighter end of the indicator arrow, for maximum, or fully left,
darker end of the arrow for maximum warming. Position
the lever anyplace in between to attain the most
comfortable temperature setting.

4.0 PREVENTIVE MAINTENANCE
4.1 Air Filter Screen
4.1.1 Inspect and clean the air filter screen monthly. If
inadequate air flow is experienced, stop using the
climate control tube and inspect the screen for blockage.
CAUTION
Debris or abrasion on the screen is one
indication of dirty air. Dirty air will cause rapid
erosion of critical parts of the climate control
tube, which will decrease efficiency and life of
the control tube.
4.1.2 To clean the air filter screen, unscrew the quick
disconnect nipple from the inlet elbow. Turn the elbow
upside down and tap it on a solid surface to remove
loose debris. The screen can be removed by tapping the
elbow described above. If the screen is wedged in place
it may be necessary to destroy it in order to remove.
Replace the screen before reassembly.
5.0 SERVICE MAINTENANCE
5.1 Service maintenance is divided into two stages.
The first stage is to replace leaking seals and to clean the
top end when the unit is otherwise working properly. (A
small leak from around the temperature control lever is
normal, and should be the same temperature as the
expelled air.) The second stage is to service and clean the
body and tube assembly. This is usually required when the
tube loses efficiency.
NOTE: Have a 08845 seal kit on hand before servicing
either stage. Clean all parts with mild soap and water,
rinse thoroughly, and dry.
5.2 First Stage Service, Refer To Figure 4
5.2.1 Remove belt bracket, lower screw, and inlet
elbow.
5.2.2 Remove the temperature control lever and set
screw stop from upper valve plate. Make a note of the
location of each before disassembly.
5.2.3 While applying pressure on the outlet connector,
remove the second retaining screw (the first was removed
with the bracket in paragraph 5.2.1) and remove the
connector from the housing. Remove the o-ring from the
connector.
5.2.4 Remove the spring and spring support washer.
5.2.5 Remove the o-ring and upper valve plate.
5.2.6 Remove the o-ring from lower valve plate.
NOTE: If the lower plate and pin come loose, refer to
Figure 4 for reassembly.

Paragraph 5.3.21.
5.3 Second Stage Service, Refer To Figure 5.
5.3.1 Remove the lower valve plate and pin. A long-
nose pliers may be needed to remove the lower plate.
5.3.2 Slide the body assembly out the end of the tube
housing. Try not to disturb the taped-on spacer.
CAUTION
Do not use force; if the unit was disassembled
correctly, it will take very little force to remove
the body assembly.
5.3.3 Remove threaded retainer and pull out the cool
end venturi assembly (venturi, o-ring, backup washer and
spring washers). Note position of spring washers.
Reassemble the same way with convex sides facing each
other.
5.3.4 Inspect the venturi assembly for wear or erosion.
Replace if necessary. If only cleaning is required, carefully
clean the slots with a brush or small screwdriver. Clean
remaining parts of the venturi assembly and replace the o-
ring from seal kit.
5.3.5 Before removing the vortex tube assembly, look
into the body and inspect the surface of the spacer for
wear; it should be flat. If it is worn, it will have to be
replaced before reassembly.
5.3.6 Carefully remove the vortex tube assembly
(spacers, venturi tube, and vortex tube).
5.3.7 On the inside of one end of the vortex tube is a
star-shaped vortex breaker. It should be intact and tight in
the tube. If the breaker is damaged or loose, replace the
tube before reassembly.
5.3.8 Remove the hot-end orifice and orifice o-ring.
5.3.9 Remove loose sealant from inside the body.
5.3.10 Clean all parts that will be reused with mild soap
and water, rinse thoroughly, and dry.

approximately 1/2 turn past hand tight.
5.3.14 Replace the rubber seal on the body’s inlet port
with the one from the seal kit.
5.3.15 If the spacer moved or was removed, align the
holes in the spacer with those in the body and tape the
spacer in place (Do not tape over the inlet port).
5.3.16 When reassembling the first stage, use new o-
rings from the seal kit.
5.3.17 Hold body assembly with hot end up as shown in
Figure 5. Place pin into body assembly and place the
lower valve plate onto body assembly over the pin. NOTE:
The lower valve plate is identified by the smooth outer
surface; the upper valve plate has three holes in the outer
surface.
5.3.18 Slide body assembly into housing. Align inlet port
and belt bracket holes. NOTE: It the lower valve plate is
correctly installed, it will be about 3/16" below the cutout in
the tube housing, and will not rotate. While handling the
assembly, hold the lower plate in place until the upper
plate is secured.
5.3.19 Apply a liberal amount of silicon sealant to the
male threads on the elbow and the bottom mounting screw
and Install both items. The elbow and disconnect should
point down when installed.

6.0 TROUBLESHOOTING
6.1 Inadequate Air Flow
6.1.1 Check filter screen for debris.
6.1.2 Make sure supply air pressure is between 90 to
100 psi. A pressure regulator and gauge must be installed
at the point of attachment (where the respirator hose is
connected to the respirable air source).
6.2 Poor Heating or Cooling Performance
6.2.1 Inadequate air flow affects cooling performance.
Refer to Paragraph 6.1.
6.2.2 The temperature of the compressed air has an
effect on the climate control tube’s discharge temperature.
Make sure that none of the lines that supply compressed
air to the climate control tube is routed near any source of
heat, such as a steam radiator, furnace, etc. When
possible avoid exposure to direct sunlight.
6.2.3 Erosion of internal parts: Compressed air moving
through the control tube will eventually wear critical
components. Dirty air accelerates wear of internal parts.
6.2.4 Vortex breaker may be loose, worn, or damaged.
Inspect the breaker per Sections 5.2 & 5.3.
6.3 Ice Forming on Air Tube
6.3.1 Water in the air line will freeze when temperature
reaches 32 degrees. To avoid icing do one of the
following:
•Lower the dew point of the compressed air below that
of the exhaust air.
•Periodically move the temperature control lever
toward the cooler position to defrost the tube
•Lower the outlet temperature enough to keep exhaust
air from freezing.
