    3.2 TRANSPORT & STORAGE INSTRUCTIONS The device shall be transported and stored in dry place and protected from weather effects with temperature range from -15 to +50°C. During loading and unloading the instructions stated on the packaging shall be observed. Due to the transport and thermal dilating, excessive enamel may fall of the heaters with exchangers on the tank bottom.

  • Page 32: Assembly Guide For Zip-Fastener Insulation

    4 ASSEMBLY GUIDE FOR ZIP-FASTENER INSULATION (Only concerns heaters with the capacity of 750 and 1000 litres) Two people are enough to implement the insulation assembly; three people are required for larger boilers; the assembly must be implemented in areas with the temperature of at least 18°C. If the insulation includes tank bottom insulation, the latter must be mounted first.
