HEATING & COOLING
ALDE
®
HEATING SYSTEM
Most nuCamp campers are equipped with the
Alde
®
Hydronic Heating System. This system is
designed to provide warmth and comfort in all
weather conditions.
Advantages of the Alde
®
System:
• It provides a much quieter, gradual warmth that spreads through the
camper, as opposed to loud blasts of air from regular RV furnaces.
• The Alde
®
System serves a dual purpose, not only heating the space
but providing on-demand hot water and continuous hot water when
combined with the Alde Flow.
• Both propane gas (with 12V) and 120V shore power can be used to
fuel the Alde
®
System.
It may take a little practice to learn how to operate the Alde
®
System. But
once you do, you will appreciate its performance and dependability.
Some basic information about the Alde
®
System set-up in your
nuCamp camper:
• The Alde
®
Hydronic Heating System is simple but elegant, with a
design that dates to the early 1700’s in Sweden. The Alde
®
System
was especially designed for RV use in the cold north and the
company has had many years of experience in this. This makes
Alde
®
ideal for use in nuCamp campers.
• Cabinetry and furniture inside the camper is specifically designed
to facilitate natural heated air movement. It is important to make
sure that wall cut outs and vents in cabinetry is kept clear for
optimum heating and airflow.
• Glycol fluid is heated in a boiler, pumped around pipes to heat
emitters and then radiates heat naturally into the air. The hot water
is heated in the same way.
• The heating fluid is propylene glycol antifreeze, and as it is heated,
it exchanges heat through a stainless-steel jacket with the domestic
hot water cylinder/tank. As a result, the water is heated at the same
time the glycol is heated. This makes the Alde
®
System very efficient.
• The Alde
®
System’s computerized electronics (such as the control
panel) use 12V Power, and the heating will run off 120V and /
or propane. Whether you have the unit on propane or 120V, it will
always require a small amount of 12V power (.6amps/hour)
• The Alde
®
3020 Compact Boiler is located underneath the dinette
area. To access, lift the dinette cushions and remove the lid.
• Typical warm-up time for the Alde
®
System from cold to a
comfortable temperature in the camper is about one hour. Take this
into consideration when using the heat system. If it takes longer
than this, have your dealer troubleshoot the system.
When using the Alde
®
System for the first time:
1. Make sure your Alde
®
bypass valve is turned to “Normal” Operation.
2. Confirm there is no RV antifreeze in the Alde
®
Domestic Water Tank.
This can occur if the unit has been winterized.
Hot water at temperatures above 120°F
(49°C) can cause serious scalding injuries
and in extreme cases, death. Always test
water temperature before showering.
WARNING
3. Check your Alde
®
expansion tank. The glycol fluid level must be at least one inch above the
minimum line. This may need to be topped off after first use.
4. Make sure you have a shore power connection or a full propane tank and charged 12V battery.
The Alde
®
will run off 120V shore-power alone, or off propane and 12V.
5. If you have checked all the above, you are ready for operation. Power on the Alde
®
monitor
mounted in the nuCamp control panel, select a power source, adjust to your desired
temperature and enjoy the warmth and comfort of the Alde
®
Heating System.
Most of this information was obtained from the Alde
®
3020 Compact Manual. For complete details on
operating the Alde
®
Heating System, please see the included operator’s manual in your Owner’s Packet.
ALDE
®
FLOW
Basic information about the Alde
®
Flow function:
1. The Alde
®
Flow functions as a preheater for your domestic water supply. About the size of a shoe
box, you will find it installed beside the boiler if your camper is equipped with it.
2. The Flow is not a hot water reserve tank but rather serves as a heat exchanger assistance to
the boiler.
3. There are no electric heating elements or combustion chambers inside the Flow.
4. The boiler pumps hot glycol into the Flow where it warms the cold water coming from the fresh
water tank by convection, taking the chill off the cold water. The warmed water is then pumped
into the boiler and further heated.
5. The Flow lightens the load on the boiler and increases the amount of hot water available for
showers. The boiler can provide more hot water with the extra assistance.
6. With the Alde
®
Flow installed there is an extra safety relief valve that needs to be drained when
winterizing the plumbing system.
7. Controls for the Alde
®
Flow are all built into the Alde
®
System. Operate the Alde
®
System as
normal. The Flow does not have separate controls.
Consult the Alde
®
Flow operator manual for detailed instructions on operation. A copy is included in
the Owner’s Packet.
AIR CONDITIONING
Important information about operating air conditioners in your camper:
• Starting an air conditioner early in the day will not only lower temperatures, it will remove excess
humidity and help the camper stay cool when the day gets hot.
• The air conditioner assists in ventilating the camper and promoting a healthy air flow by recycling
stale air and bringing in fresh air.
• Roof mounted air conditioners must be added to the total clearance measurement. If you hit an
object because of low overhead clearance, the roof top air conditioner will likely be damaged first.
• The air conditioner is the largest single load on the electrical system.
• The air conditioner only operates on shore power. When camping without shore power you will
need to use an appropriately sized generator to run the air conditioner. Use 30 Amp Shore Power
only. Running the system on a 15amp circuit can overload the circuit.
• DO NOT use the microwave and air conditioner at the same time. It will trip breakers.
