General information
Introduction
General information prior to installation
The following documents are supplied with the unit:
• Installation instructions/Software instructions
• User manual
• Wiring diagram
The instructions can be downloaded from the Nilan website: http://www.nilan.dk/da-dk/forside/
download
If you have further questions on unit installation after reading the instructions, contact your nearest
Nilan distributor, who can be found on www.nilan.dk/forhandlere.
The purpose of these instructions is to give the installer advice on correct installation and maintenance
of the unit.
The unit must be started up immediately after installation and connection to the duct system. In
periods where the ventilation system is not in operation, humid air from the rooms may penetrate into
the ducts and form a condensate. The condensate may leak out of the valves and damage furniture and
floors. In addition, condensate may form inside the unit, damaging the unit's electronics and fans.
The unit is supplied fully tested and ready for operation.
Unit type
Product description
Compact P GEO is a ventilation unit with an integral heat exchanger that also produces hot water for
domestic use as well as central heating via an 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 ventilation part draws the humid, vitiated air out of the dwelling via the bathroom, WC, kitchen and
utility room and introduces fresh air into the habitable rooms, i.e. living room, bedrooms and office. The
could outdoor air is heated up in the heat exchanger (heat recovery) by the warm extract air.
In addition to a (counterflow) heat exchanger, Compact P has an integral heat pump. The heat pump
uses the heat remaining in the extracted air following heat recovery in the heat exchanger to produce
hot water. 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 heat pump can be used to heat the supply air during periods in which not domestic hot
water is being produced. The supply air can be heated up to 34 ºC.
As it is a reversible heat pump, it can be used in summer to cool the supply air. Compact P is able to cool
the supply air by up to 10 ºC. However, it will not function as an air conditioning unit, as it operates with
a relatively low air change rate. Cooling of the supply air removes humidity from the indoor air,
providing good comfort for persons in the dwelling, even if the indoor temperature is high. Compact P is
able both to provide cooling and produce domestic hot water, so it could be said that the cooling of the
supply air is "free of charge".
6

The energy-efficient and low-noise GEO ground source heat pump heats the home via floor heating or
low-temperature radiators. It extracts energy form the ground. The heat pump has an electrical power
supply to help it to function during very cold periods. The GEO can cool the dwelling during the summer
by passive cooling, using either the floor 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 preheating element for frost protection
In longer periods of sub-zero temperatures, the high-efficiency counterflow heat
exchanger will ice up. To avoid icing, it is recommended that an electrical
preheating element is mounted.
The preheating element uses very little energy, but ensures efficient heat
recovery without de-icing, thus achieving an overall saving in energy
consumption.
Adjustable water comfort heater
A water comfort heater can be used to increase supply air temperature to the
desired level. It is fitted in the supply air duct and must be connected to the
primary heat supply.
Supplied with a two-way regulating valve, temperature sensor and frost
thermostat.
Electric heating element
An electric heating element allows the supply air temperature to be raised to the
desired level. Electric heating elements are supplied for mounting in the supply
air duct, and are provided with the necessary sensors.
Pollen filter F7
The unit is supplied as standard with a G4 filter.
If persons in the dwelling suffer from a pollen allergy, there is an option for
mounting a F7 pollen filter in the outdoor air inlet to minimise the pollen in the
indoor air.
EM box
With an EM box it is possible to divide the extract air between the kitchen and
bathroom.
If the cooker hood is operating via the unit and is switched on, air extraction from
the bathroom reduces slightly to allow sufficient air for the cooker hood to
extract kitchen fumes.
The EM box has a metal filter which efficiently separates grease particles from
the cooker hood air, thus protecting the unit.
CO2sensor
Fitting a CO2sensor means the ventilation speed can be pre-programmed to run
higher ventilation levels in the event of high CO2level in the extracted air. CO2
levels can be programmed.
12

Safety group
The safety group, which is made of brass, consists of a stop valve with an integral
non-return valve, a safety valve and drain cock. It can be installed directly
beneath the hot water tank.
Safety features
During periods with cooling ventilation, hot water in the tank can reach very high
temperatures - up to 80 ºC.
A maximum temperature of up to 60 ºC can be set in the control system to
prevent scalding, but active cooling is then limited.
To make full use of the cooling function, scalding protection should be fitted that
mixes hot water with cold to bring the temperature down.
If a solar panel is used to supplement hot water heating, scalding protection must
be fitted.
Flexible silencing
To facilitate later servicing of the unit, we recommend fitting a flexible
connection between the unit and the duct system.
Nilan's sound damping flexi-hose gives good sound damping both to the duct
system and to roof stacks.
Trolley
A trolley makes it possible to lift the unit of the pallet without physical strain.
The same trolley can be moved to wheel the unit around.
SHW hot water tank
If there is a large demand for hot water, a 250 litre hot water tank can be
connected.
The hot water tank is heated by the central heating system’s heat pump and/or
via solar panels.
The water runs from the SHW tank, through the DHW tank in Compact P, before
running into the domestic hot water supply.

Installation
Installing the unit
Transport into the dwelling
Compact P is supplied in one piece on a pallet, packed in cardboard.
It 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. When lifting the units with the supplied straps, these must be at an angle of max. 45°
from the vertical.
Nilan also offers a 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
ATTENTION
When setting up the unit, consideration must always be given to future servicing and
maintenance.
It must be easy to replace filters, and it must be possible to perform tasks such as removing the
heat exchanger, replacing fans and other components.
ATTENTION
Aminimum free space in front of the unit of 60 cm is recommended.
It is important that the unit is level in order to achieve proper run-off from the condensate tray.
The unit should be positioned on a level and vibration-free substrate. In itself, the unit is low-noise and
low-vibration, but even so, account must be taken of possible vibrations which could be transferred to
building parts. We recommend maintaining a minimum 10 mm gap from building parts and other fixed
equipment.
ATTENTION
For noise reasons, it is recommended that the unit is positioned with its rear panel against an
outer wall.
At the lower rear and sides there are punched
areas which can be clipped out.
This avoids the necessity of cutting holes
yourself.
The rear angle iron on the base frame can be
removed, allowing the unit to be pushed up
against the wall, thereby concealing the water
connections.
ATTENTION
If a screen is mounted over the Compact P, it must be easy to dismantle this.

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.
ATTENTION
Is is important to pressure test the pipes for tightness one by one immediately before covering
with soil, as during handling.
