Zodiac Z550iQ Instructions For Installation And Use Manual page 4

• During the appliance's annual sealing test in accordance with applicable legislation,
the high and low pressure switches must be checked to ensure that they are
securely fastened to the cooling circuit and that they cut off the electrical circuit
when tripped.
• During maintenance work, ensure there are no traces of corrosion or oil around
the cooling components.
• Before beginning work on the cooling circuit, stop the appliance and wait for a few
minutes before fitting the temperature and pressure sensors. Some elements such
as the compressor and piping may reach temperatures in excess of 100°C and high
pressures with the consequent risk of severe burns.
TROUBLESHOOTING
• All brazing must be carried out by qualified brazers.
• Replacement pipes must always be made of copper in compliance with standard
NF EN 12735-1.
• Leak detection; pressure test:
- never use oxygen or dry air (risk of fire or explosion)
- use dry nitrogen or the mixture of nitrogen and refrigerant indicated on the
information plate,
- the test pressure for both the high and low pressure circuits must not exceed
42 bar (for R410A) in cases where the appliance is equipped with the optional
pressure gauge.
• The high pressure circuit pipes are made of copper and have a diameter equal to or
greater than 1''5/8. A certificate as indicated in §2.1 in compliance with standard
NF EN 10204 must be requested from the supplier and filed in the installation's
technical file.
• Technical data relative to the safety requirements of the various applicable directives
are indicated on the information plate. All this information must be recorded in the
appliance's installation manual, which must be kept in its technical file: model,
code, serial number, maximum and minimum OT, OP, year of manufacture, CE
marking, manufacturer's address, coolant and weight, electrical parameters,
thermo-dynamic and acoustic performance.
Recycling
This symbol is required by the European directive DEEE 2012/19/EU (directive on waste electrical and electronic
equipment) and means that your appliance must not be thrown into a normal bin. It will be selectively collected
for the purpose of reuse, recycling or creating value. If it contains any substances that may be harmful to the
environment, these will be eliminated or neutralised. Contact your retailer for recycling information.
