Introduction
Read this manual thoroughly before operating or servicing this unit.
Warnings, Cautions, and Notices
Safety advisories appear throughout this manual as required. Your personal
safety and the proper operation of this machine depend upon the strict
observance of these precautions.
The three types of advisories are defined as follows:
WARNING
Indicates a potentially hazardous situation which, if not avoided, could
result in death or serious injury.
CAUTIONs
Indicates a potentially hazardous situation which, if not avoided, could
result in minor or moderate injury. It
could also be used to alert against
unsafe practices.
NOTICE
Indicates a situation that could result in equipment or property-damage only accidents.
Important Environmental Concerns
Scientific research has shown that certain man-made chemicals can affect the
earth’s naturally occurring stratospheric ozone layer when released to the
atmosphere. In particular, several of the identified chemicals that may affect
the ozone layer are refrigerants that contain Chlorine, Fluorine and Carbon
(CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs).
Not all refrigerants containing these compounds have the same potential impact
to the environment. Trane advocates the responsible handling of all
refrigerants-including industry replacements for CFCs and HCFCs such as
saturated or unsaturated HFCs and HCFCs.
Important Responsible Refrigerant Practices
Trane believes that responsible refrigerant practices are important to the
environment, our customers, and the air conditioning industry. All technicians
who handle refrigerants must be certified according to local rules. For the
USA, the Federal Clean Air Act (Section 608) sets forth the requirements for
handling, reclaiming, recovering and recycling of certain refrigerants and the
equipment that is used in these service procedures. In addition, some states
or municipalities may have additional requirements that must also be adhered
to for responsible management of refrigerants. Know the applicable laws and
follow them.
WARNING
Proper Field Wiring and Grounding Required!
Failure to follow code could result in death or serious injury. All field
wiring MUST be performed by qualified personnel. Improperly installed and
grounded field wiring poses FIRE and ELECTROCUTION hazards. To avoid these
hazards, you MUST follow requirements for field wiring installation and
grounding as described in NEC and your local/state/national electrical codes.
WARNING
Personal Protective Equipment (PPE) Required!
Failure to wear proper PPE for the job being undertaken could result in death
or serious injury. Technicians, in order to protect themselves from potential
electrical, mechanical, and chemical hazards, MUST follow precautions in this
manual and on the tags, stickers, and labels, as well as the instructions
below:
· Before installing/servicing this unit, technicians MUST put on all PPE
required for the work being undertaken (Examples; cut resistant
gloves/sleeves, butyl gloves, safety glasses, hard hat/bump cap, fall
protection, electrical PPE and arc flash clothing). ALWAYS refer to
appropriate Safety Data Sheets (SDS) and OSHA guidelines for proper PPE.
· When working with or around hazardous chemicals, ALWAYS refer to the
appropriate SDS and OSHA/GHS (Global Harmonized System of Classification and
Labeling of Chemicals) guidelines for information on allowable personal
exposure levels, proper respiratory protection and handling instructions.
· If there is a risk of energized electrical contact, arc, or flash,
technicians MUST put on all PPE in accordance with OSHA, NFPA 70E, or other
country-specific requirements for arc flash protection, PRIOR to servicing the
unit. NEVER PERFORM ANY SWITCHING, DISCONNECTING, OR VOLTAGE TESTING WITHOUT
PROPER ELECTRICAL PPE AND ARC FLASH CLOTHING. ENSURE ELECTRICAL METERS AND
EQUIPMENT ARE PROPERLY RATED FOR INTENDED VOLTAGE.

Rigging Guidelines
WARNING Heavy Objects!
Failure to follow instructions below could result in unit dropping which could
result in death or serious injury, and equipment or property-only damage.
Ensure that all the lifting equipment used is properly rated for the weight of
the unit being lifted. Each of the cables (chains or slings), hooks, and
shackles used to lift the unit must be capable of supporting the entire weight
of the unit. Lifting cables (chains or slings) may not be of the same length.
Adjust as necessary for even unit lift.
General Guidelines (not applicable to all models and sizes)
· When tower is removed from trailer, mark the exact location of tower on
trailer. Tower should be replaced in the same location with outlet water
connections on the same side of the trailer. The trailer must be returned in
the same condition in which it was delivered.
· Lifting plates are located on each side of the top of the 500-ton towers.
Fork pockets are located in the base of the tower. Lifting eyes are located on
each side of the bottom of the 270-ton towers.
· Drain, clean basin, and disconnect any piping and wiring before returning
unit to trailer. 500-ton dual outlet towers should be positioned with 10 inch
outlet connections on passenger side of trailer.
· When tower is reloaded in the original position, reconnect turnbuckles (if
equipped) and tighten to secure to trailer.
Important: 1000 Ton Cooling Tower is permanently trailer mounted.
· If tower is removed from trailer, the foundation on which the tower will be
operating from must support the operating weight of the tower.
· If tower remains on the trailer, operating weight will impact the landing
gear and tires. Cribbing or weight distribution plates may be required.

Maintenance
· Ensure proper chemical water treatment and bleed all of the air out of the
system. See the water treatment recommendations below.
· Before beginning any maintenance, be certain that the power is turned off
and the tower is properly locked and tagged out.
· Inspect the basin strainer and clean weekly or as often as necessary to keep
it clean.
· Check the float and float valve periodically to make sure the water level is
correct in the basin. The water level can be checked during operation by
opening the removable louver section at the valve while the pump is running
and the fans are off.
· Inspect the air louvers periodically to remove any paper, leaves, or other
debris that may be blocking airflow into the unit.
Water Treatment Recommendations
To avoid build-up of residuals in the water distribution system, water must be
bled off from the system in an amount equal to the rate of evaporation. In
addition, water quality should be checked to ensure that the chemistry is
balanced and that the water system is free from biological contamination.
It is recommended the system has a bleed line installed on the discharge side
of the system pump and should include a metering connection and valve. The
metering connection should be used to determine the bleed water volume. The
valve is used to regulate the flow. As a guideline, the bleed line and valve
should be large enough to allow bleed off of an amount of water equal to 3 US
gpm for each 100 tons cooling or use the formula Bleed (gpm) = Flow (gpm) x
Range (F) / 1,000. Confirm with your water treatment specialist to confirm the
required bleed off for your system.
In some cases, the make-up water will be so high in mineral content that a
normal bleed-off will not prevent scaling. Water treatment will be required
and qualified water treatment company familiar with the local water conditions
should be consulted. Any water treatment system used in the unit must be
compatible with the unit’s materials of construction. If a chemical water
treatment system is used, the chemicals selected must be accurately metered
and concentrations properly controlled. See Table 4 for recommended levels.
Table 4. Water chemistry guidelines
Parameter pH Hardness as CaCO3 Alkalinity as CaCO3 Chlorides as Cl TDS (Total Dissolved Solids) Silica – SiO4 Sulfates – SO4 Phosphates – PO2
Range 6.5 to 8.0 50 to 300 ppm 50 to 300 ppm 125 ppm max 1500 ppm max 180 ppm max 250 ppm max 15 ppm max
· Soft water systems should be avoided. · The use of acid should be avoided. · CAUTION – Never batch load chemicals into unit. · Always regulate chemical feed.
Control of Biological Contamination
Water quality should be checked regularly for biological contamination. If
biological contamination is detected, a more aggressive water treatment and
mechanical cleaning program is required. The water treatment program should be
performed in conjunction with a qualified water treatment company. It is
important that all internal surfaces be clean of accumulated dirt and sludge.
To minimize the risk of biological contamination prior to start-up or after an
extended shut down, it is recommended that the entire system (cooling tower,
system piping, heat exchanger, etc.) be properly cleaned. Clean all debris
such as leaves and dirt from the basin. Completely fill the basin to the
overflow level with water. Initiate a biocide water treatment or shock
treatment program prior to operating the unit. It is preferable that all such
procedures be conducted and supervised by your water treatment specialist.
CAUTION
Personal Protective Equipment (PPE) Required!
Failure to follow all safety instructions below could result in minor to
moderate injury. ALWAYS wear Personal Protective Equipment (PPE) including
goggles or face shield, chemical resistant gloves, boots, apron or suit as
required. If it becomes necessary to use cleaning agent, refer to the
manufacturer’s Materials Safety Data Sheet and follow all recommended safe
handling practices.
24
CHS-SVN08F-EN
Air Contamination
If the unit is located in an industrial area where there are chemical fumes or
particulate matter in the air the impurities will be washed out in the
recirculated water and may cause scaling or corrosion. It is important not to
locate the unit next to a smokestack because the unit will draw in these fumes
and severely corrosive conditions may result. Bleed-off will help the
situation, but if there is any sign of corrosion or scaling, a qualified water
treatment company should be contacted.
