Domestic Hot Water - Bailey Approach Autograph Series Owner's Manual

• 6 A limit, only use 1 kW electric heating.
• 10 A limit, use 1–2 kW electric heating.
• 16 A limit, use 1–3 kW electric heating.
NOTE: If the electric supply has
unstable voltage, the amperage will
also fluctuate.
The optional Alde 3010-315 load
monitor allows you to set a limit on
the current drawn by the vehicle and
the electric heating to automatically
accommodate it.

Domestic Hot Water

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 fresh water.
The boiler can produce around 12 litres of
40°C warm water per 30 minutes (at a cold
water temperature of 10°C). If only the electric
heating is used, this capacity is slightly reduced.
Only use potable fresh water. Grey water,
desalinated water, or water otherwise unfit to
drink is not suitable for use as domestic hot
water.
Where water quality is in doubt, precautions
should be taken to ensure the stainless steel hot
water cylinder is not damaged.
Always flush out the hot water cylinder before
use, especially when it has stood empty for
some time. Any steriliser products should be
suitable for use with stainless steel.
Avoid steriliser products containing sodium
hydrochlorite, for example, as these will cause
severe corrosion damage to the hot water
cylinder, which is not covered under warranty.
Read the product label or contact the product
manufacturer for details.
When the hot water cylinder is in continuous
use, it should be drained and refilled once a
month. This recreates the air cushion in the hot
water cylinder that absorbs pressure surges.
NOTE: If continuously using the hot
water cylinder in a hard water area,
fit an in-line scale inhibitor to
minimise the effects of limescale.
Target hot water temperature is greater than 50
°C in normal operation, to prevent the growth
of Legionella. Over 50 °C , the hot water will be
heated to the maximum achievable temperature
at the time. This allows the hot water to achieve
disinfection temperatures, and increases warm
water performance.
If scalding hot water temperatures are a
concern – such as with the young, elderly or
infirm – thermostatic mixing valves (TMVs)
can be fitted, and may be required by local
regulations.
IMPORTANT: Always drain down and
completely empty the hot water
cylinder when there is risk of frost,
unless the vehicle is explicitly stated
to be self-winterising by the vehicle
manufacturer.
WARNING: Failure to drain the hot
water cylinder when there is a risk of
frost may result in frost damage,
which is not covered under warranty.
