Water quality requirements
Requirements for water quality
The hot water tank in the Nilan units is made of steel, which has been given a double enamelling, to ensure an extra long service life. In
addition, the tank is equipped with a sacrificial anode as extra protection. It is important that the sacrificial anode is replaced regularly.
Most units are equipped with an electronic monitoring sacrificial anode, which gives an alarm on the user panel when it is time to
replace it.
In order for the sacrificial anode to function and protect the tank, it is required that the water quality complies with the following:
• Electrical conductivity (EC): Between 30 mS/m and 150 mS/m (millisiemens pr. m) @ 25 °C
• Chloride must be below 250 mg/L @ 65 °C
If the above criteria are not met, the sacrificial anode will not work as intended, after which the tank will be corroded., to

From factory, the unit has been tested and is ready for operation.
ATTENTION
The unit must be started up immediately after installation and connection to the duct system.
When the ventilation unit is not in operation, humidity from the rooms will enter the duct system and create condensate
water that can run out of the valves and cause damage to floors and furniture. Condensation may also form in the ven-
tilation unit, which can damage its electronics and fans.

Unit type
Product description
Compact P is a ventilation unit with heat recovery, that has a built-in heat pump, which is used for the production of domestic hot wa-
ter, and which is also able to heat and cool the home by central heating via a ground source heat pump.
Compact P is designed for air flows of up to 275 m3/h at 100 Pa external counter-pressure. Compact P XL can handle air flows up to
430 m3/h at 100 Pa external counter-pressure.
The unit is primarily used in residential construction such as single-family houses and apartments. It ventilates the home by drawing
out the moist and bad air via valves in e.g. bathrooms, toilet, kitchen and utility room, and introduces fresh outdoor air in via valves in
living rooms such as. living room, bedrooms and family room.
The cold outdoor air is heated via the high-efficiency counterflow heat exchanger by the hot exhaust air. The heat loss that occurs via
heat recovery, the built-in heat pump use to produce domestic hot water. All the energy in the exhaust air is utilized, and you have not
really seen any heat loss that you experience with an ordinary ventilation unit. In case of high hot water consumption, there is a 1.5 kW
electric supplement heater in the hot water tank, which can also be used to heat the water.
In the winter, the built-in heat pump can heat the supply air up to 34 ° C, and thus contribute to heating the home. When the supply air
is heated, at the same time a little heat is deposited in the hot water tank and ensures a constant high hot water temperature.
The heat pump has a reversible cooling circuit, which means that the cooling circuit can be turned and it can cool the supply air in the
summer. Compact P can cool the supply air by up to 10 ° C in relation to the outdoor air. Due to the low air exchange, usually 1/2 time
per hour, it will not act as an air conditioning system. However, when cooling, moisture in the supply air is removed, which results in a
lower humidity in the home. The lower humidity means that it is easier to withstand a slightly higher temperature, which therefore pro-
vides good comfort in the home.
When Compact P cools the supply air, the energy is deposited in the hot water tank, and it can thus be said that “free” domestic hot wa-
ter is produced during those periods.
The energy-efficient and low-noise GEOthermal heat pump heats the home via floor heating or lowtemperature radiators. It retrieves
the energy from the earth. The heat pump has an electrical power supply to help it to function during very cold periods. GEO can cool
the home in the summer with passive cooling, either through the underfloor heating system or fan coils.
The GEO ground source heat pump can also be used to help produce hot water for domestic use, either by pre-heating the water in a
buffer tank, or directly in a Compact P hot water tank, if bought with a solar coil.

Accessories
Electrical pre-heating element for frost protection of the unit
CO2-sensor
EM-box
Safety group
Safety group with scalding protection
If your ventilation unit is not a Polar version with an integral pre-heating element, we recommend that you
purchase an external pre-heating element as frost protection of the ventilation unit.
During prolonged periods of frost, the high efficiency counterflow heat exchanger will ice up. To prevent ice
formation, we recommend that you install an electrical pre-heating element.
The pre-heating element consumes limited energy and it ensures efficient heat recovery without periods of
defrosting the counterflow heat exchanger. You thereby achieve an overall reduction in energy
consumption.
If you want to adjust the fan speed level according to use of the dwelling/building (amount of people), you
can retrofit a CO2-sensor.
You select the CO2-level you want via the control panel. If this level is exceeded, ventilation will increase.
If you want to run the cooker hood via the ventilation unit, in some cases there may be insufficient air for
cooker hood extraction.
If you install an EM-box, you can regulate the extracted air when the cooker hood is in operation, so that less
air is drawn from, for instance, the bathroom and the utility room. This will allow enough air for the cooker
hood to extract sufficiently.
The EM-box is fitted with a metal filter that cleans the air in the cooker hood of grease particles efficiently. It
thereby protects the ventilation unit.
By law, a safety group must be fitted for the cold water connection to the hot water tank.
Nilan offers a safety valve in brass with the following functions:
• Safety valve
• Check valve
• Stop valve
• Drain tab
The control has a software scald protection that ensures that the water in the hot water tank does not
gets too hot.
If you have a large cooling and / or heating need, it may be necessary to deactivate the software scald
protection. The water in the hot water tank can be up to 90 ° C, which is why you need to install a safety group
with scald protection.
If a solar panel is used to heat the domestic hot water via the supplementary coil in the hot water tank, a
safety group with scald protection must be fitted.

Vibration absorbers
Flexible sound damper
Pollen filter
Trolley
SHW hot water tank
It is important to ensure that the ventilation unit does not transfer vibrations to the building. The ventilation
unit should therefore be placed on a vibration absorbing material.
Nilan can supply effective vibration absorbers to place under the ventilation unit. They are sold in packs of 4.
To make it esay to service the unit in the future, we recommend that you fit a flexible connection between the
unit and the duct system.
Nilan flexible sound damper absorbs sounds effectively from both the duct system and from roof stacks.
The ventilation unit comes, as standard, with a plate filter to protect the unit.
If the dwelling is used by anybody with, for instance, pollen allergies, you may benefit from purchasing a
pollen filter. This should be placed in the outdoor air intake, which will reduce the pollen count in the dwelling.
A Nilan trolley makes it easy to transport the heavy units into the home, without having to carry out heavy
lifting yourself with the risk of injury.
A set consists of two lifting carts that are fastened on each side of the unit while it is standing on the pallet.
Using the two handles, lift the unit off the pallet and drive it to where it is to be used.
The SHW tank is a Nilan-produced 250 liter hot water tank with built-in solar coil and heat pump supplemental
coil that can be connected to all Compact P solutions.
The SHW tank is prepared for mounting a temperature sensor for external solar heat control. The supple-
mental spiral is intended for solar heating systems with solar collectors of approx. 4 m2.
The steel container is with double enamelling to guarantee a perfect water quality. It comes with a 1.5kW in-
sert heating element as well as an electrically monitored magnesium sacrificial anode, both of which are con-
trolled by the CTS automatics.
The solution is ideal for families with a large consumption of hot water.

13
Installation
Assembly
Transport into the dwelling
Compact P is supplied in one piece on a pallet, packed in cardboard.
You can use Nilan lifting trolley, with which the unit can be lifted directly off the pallet and into the building. If the filter box is removed,
the unit can be manoeuvred through an ordinary door.
Positioning of unit
The unit should be positioned on a level and vibration-free substrate, with good access for servicing and filter change.
The unit is fitted at the factory with 4 lifting straps, one for each top corner.
This makes it possible to lift in the unit with a crane, which is a great advantage if the terrain does
not allow you to drive with a lift truck.
When lifting the units with the supplied straps, these must be at an angle of max. 45°from the
vertical.
ATTENTION
When setting up the unit, consideration must always be given to future servicing and maintenance, therefore a free
space in front of the unit of at least 60 cm is recommended.
ATTENTION
To achieve a proper run-off from the condensate tray, it is important that the unit is installed in level.
ATTENTION
If a screen is mounted over the Compact P, it must be easy to dismantle this.
At the lower rear and sides of the unit, there are punched areas
which can be clipped out, so you do not cuts the holes yourself.
The rear angle iron on the base frame can be removed, allowing the
unit to be pushed closer to the wall, thereby concealing the water
connections.

Ground collector circuit
Examples of the laying
By laying the geothermal circuit there are some range distances, which need to be observed to get a unit which will have an effective
and smooth operation. Further local authorities may make requirements for installation and acceptance of the facility before entry
into use.
In some cases where there is less space vertically holes is drilled for hoses, but most lay the hoses horizontally. Below are some
examples of laying the ground collectors.
