1. GENERAL INFORMATION
1.1 - Preface
Your heat exchanger will give you full satisfaction provided you maintain it well, in full, and diligently.
- Be sure to keep the following documents in a safe place:
1) this instruction and maintenance manual (supplied with the heat exchanger);
2) the EC declaration of conformity, where necessary. Supplied upon request.
- Your plate heat exchanger has temperature and pressure limits and is highly sensitive to sudden changes in these parameters.
Therefore, all necessary precautions must be taken to avoid operating outside the limits indicated on the data plate.
1) Excessive temperatures will damage the gaskets (install the appropriate safety thermostats, etc.).
2) Excessive operating pressures or differential pressures will damage the gaskets and plates (install the appropriate safety
valves, etc.).
- Plate heat exchangers are highly sensitive to water hammers. The control must be designed accordingly and QUARTER-TURN
VALVES MUST NOT BE INSTALLED ON ANY OF THE CIRCUITS.
- Given the large number of gaskets, leaks may occasionally occur. To protect against this eventuality, install protective screens
if dangerous fluids are used or the temperatures rise to above 60°C.
- CIAT may not be held liable for any damage or injury resulting from failure to follow the instructions in this manual.
- CIAT is not liable for any consequences that may result from the accidental mixing of the fluids used in the heat exchanger.
1.2 - Standards
- Official checks: some heat exchangers must be regularly checked by official bodies. It is the operator’s responsibility to organise
these checks directly with the competent bodies. The dossier sent to our contractors must therefore be kept in a safe place.
- The heat exchanger category set out in the European Pressure Equipment Directive 97/23/EC is specified on the data plate on
the heat exchanger and on the last page of this manual.
- You must make sure that the installation complies with the directives and legislation in effect in the country of operation.
- This heat exchanger must not be used for purposes other than those stated on the order documents. In particular, do not use
fluids other than those specified at the time of ordering.
- Scrupulously comply with the operating conditions set out in the order documents. These were used to determine the equipment
category set out in the European Pressure Equipment Directive. CIAT shall not be held liable for any consequential or incidental
damages resulting from failure to do so.
- CIAT must be notified of any changes in the operating conditions and will inform you of the procedure to follow.
1.3 Warranty
- Unless otherwise indicated, our equipment is guaranteed for 12 months after commissioning and no more than 18 months after
invoicing. Our warranty is limited to the replacement of defective parts used under the intended conditions. However, it does not
cover normal wear and tear, deterioration resulting from corrosion, dirt or the use of fluids incompatible with the materials used
in the heat exchanger, or consequential damage.
- Gaskets are warranted for six months.
- Keep a maintenance log. You may be requested to provide this in order to benefit from the warranty.
- The warranty is valid only if the heat exchanger is operated under the conditions set out in the order documents. It will be applied
only if the pressures and temperatures of the fluids can be easily measured on the heat exchanger’s inlets and outlets and the
maintenance log is kept up to date.
- The plate pack is sealed by a strap (warranty seal) which serves as proof that the heat exchanger has never been disassembled.
Removing this strap will void the warranty.
- Spare parts are warranted only if the storage instructions have been followed (see the section on storage).
- CIAT must be promptly notified of any defects, in writing. If CIAT’s liability for the defect is proven, CIAT pledges to react quickly
and to remedy it within the terms of the warranty.
1.4 - Residual risks :
damage > cause (prevention)
POSSIBLE BODILY INJURY
- Unit tips over > Failure to follow the handling or anchoring instructions (the unit has a very high centre of gravity; follow the
harnessing instructions; anchor the unit to the floor).
- Burns > Direct contact with the unit while in operation or with scalding or corrosive fluids following a leak (cut off the supply to
the unit; set up barriers around it; wear PPE = Personal Protective Equipment).
