thesystem.
• Always drain down the freshwater
system if there is risk of frost; in
winter,forexample.Youmaycontinue
tousetheboilerwithnofreshwaterin
the system, as required; no damage
canresult.
• Always replace the HTF in
accordance with the antifreeze
product’s lifespan. . If in any doubt,
replacetheHTFafter2years.
• Onlysterilisethefreshwatersystem
with a product suitable for stainless
steel.
• Do not place stowage in the boiler
compartment.
• Do not position awnings, tents or
other enclosures around the ue

Being a combi-type boiler, the Alde 3020
CompactHEhasanintegrated,stainlesssteel
hot water cylinder that holds approximately
8.4litresoffreshwater.
The boiler can produce around 12 litres of
40°Cwarmwaterper30mins(atacoldwater
temperature of 10°C). If only the electric
heating is used, this capacity is slightly
reduced.
Thehotwatershouldnotbeusedfordrinking
orcooking.
Alwaysushoutthehotwatercylinderbefore
use, especially when it has stood empty for
sometime.

Avoid steriliser products containing sodium

severe corrosion damage to the hot water
cylinder,whichisnotcoveredunderwarranty.

Whenthehotwatercylinderisin continuous
use, it should be drained and relled once a
month. This recreates the air cushion in the

Targethotwatertemperatureisgreater

thegrowthofLegionella.Over50°C,the

allowsthehotwatertoachievedisinfection
