This manual provides information needed to install, oper-
ate and carry out the maintenance of the LaZerWeld II 
(LZWII) plate heat exchanger.

SAFETY CONSIDERATIONS

Use and maintain the LZWII in accordance with FRICK’s 
instructions in this manual. Faulty handling of the heat 
exchanger may result in serious consequences with inju-
ries to persons and/or property damage. FRICK does not 
accept responsibility for any damage or injury that has 
resulted from not following the instructions in this manual.

Use the heat exchanger in accordance with the specified 
configuration of material, media types, temperatures, and 
pressure for the specific LZWII.

The following models are covered in this manual:

•  LZWII-2M
•  LZWII-4B
•  LZWII-4E
•  LZWII-6B
•  LZWII-8K
•  LZWII-8B
•  LZWII-12M

WARRANTY CONDITIONS

The warranty conditions are usually included in the signed 
sales contract before the order of the delivered LZWII. 
Alternatively, the warranty conditions are included in 
the sales offer documentation or with a reference to the 
document specifying the valid conditions. If faults occur 

during the specified warranty period, always consult your 

local FRICK Representative for advice.

Report the date when the heat exchanger was put into 
operation to the local FRICK Representative.

ADVICE

Consult your local FRICK representative for information on 
the following:

•   New plate pack dimensions if you intend to change the 

number of cassettes (twin plates)

•   Selection of gasket material if operating temperatures 

and pressures are permanently changed, or if another 
medium is to be processed in the LZWII

ENVIRONMENTAL COMPLIANCE

FRICK endeavours to perform its own operations as cleanly 

and efficiently as possible, and to take environmental 

aspects into consideration when developing, designing, 
manufacturing, servicing, and marketing its products.

Unpacking

Packing material consists of wood, plastics, cardboard 
boxes and, in some cases, metal straps.

•   Wood and cardboard boxes can be reused, recycled, or 

used for energy recovery.

•   Ensure plastics are recycled or burnt at a licensed 

waste incineration plant.

•   Send metal straps for material recycling.

Maintenance

•  Send all metal parts for material recycling.
•   Oil and all non-metal wear parts must be taken care of 

in agreement with local regulations.

Scrapping

At end of use, recycle the equipment in accordance with 
the relevant, local regulations. Besides the equipment 
itself, any hazardous residues from the process liquid must 
be considered and dealt with in a proper manner. When in 
doubt, or in absence of local regulations, contact the local 
FRICK sales company.
