Compact P is a heat recovery ventilation system with a capacity of up to 330m3/h at 100Pa exter-
nal counter pressure. The energy of the exhaust air is transferred via a heat pump to a 180litres
hot water tank as first priority and to the inlet air as second priority.
The system can be equipped with G3 duct filter. Other optional extras are also available, including
hygrostat and pollen filter unit.
The system is operated via NILAN CTS602 controls offering a wide range of functions, including
menu-based operation, weekly programming, timed filter alarm, fan speed adjustment, etc. The
NILAN CTS602 controls are described in a separate manual supplied together with the system.
For details of spare parts and accessories under Figure 22 “accessories”
Compact P is supplied in a white Aluzink cabinet, fully tested and ready to operate. Installation and
start-up must only be performed by a qualified electrician.

Electrical connection

All wiring (power supply, safety circuit breaker, etc.) must only be fitted by a qualified
electrician.
The system must be connected in accordance with the accompanying wiring diagram.
The system is supplied with a 1 m test cable for the CTS602 control panel. The control panel must
be connected to the CTS602 controls using twisted pair cable type 2x2x0.25mm2(max. length
50m).
The CTS602 control panel should be installed in a dry, frost-free location. A temperature sensor
built into the control panel prevents further cooling of the building should the primary heating sys-
tem fail by switching the ventilation system off if control panel temperature falls below a preset
level.

Installing Compact P

When installing the unit, it is important to take future service and maintenance into ac-
count. There should be a minimum clearance of 602mm in front of the unit, measured
from the Compact P front panel.

When lifting the unit with straps it is important that the straps has an angle of maximum
45°C off perpendicular.
Individual connectors have been marked out at the factory to facilitate installation. Please note the
attached labels. The connectors should be connected to the duct system using flexible adapters
(flex tube, soundproofed flex tube or similar).

The unit must be installed and leveled on a firm, vibration-free surface. There should be at least
10mm clearance to walls or other permanent installations. Although the unit itself is practically
noise and vibration free, care must be taken to prevent any vibration from being propagated to ad-
joining parts of the building.
The rear angular slide bar of the base frame of the Compact P can be removed in order to make it
possible to push the unit towards the wall to hide water connections etc.
It is important that the condensation outlet of the Compact P be connected to a drain. The unit is
supplied complete with water trap. The outlet should be led frost-free with steady decline to the
nearest drain. The safety valve overflow must also be led to a drain.
If Compact P is enclosed by any covering, it must be possible to remove the covering easily.

Condensation drain/water trap
Compact P is supplied with 20mm condensation outlet (PVC, GF fittings). The unit is also equipped
with built-in water trap.

The condensation outlet must be led frost-free with a steady decline of at least 1 cm/m to
the nearest drain. The safety valve overflow must also be led to a drain.

In order to prevent ice formation, it may be necessary to equip the condensation outlet
with a heating cable where frost is possible Protecting the condensation outlet from frost
is the responsibility of the fitter.

Water connection
The inner tank surface is enamelled and the tank is equipped with a sacrificial anode.
All connectors have 3/4” threads, with the exception of the anode access which is a 5/4” sleeve.
All water pipes are connected to the bottom of the unit.
If required, hot water circulation can be established by fitting a non-return valve to the recirculation
connector of the tank after inserting a 80cm long circulation pipe (optional accessory) into the tank.
See figure 3 below.
If hot water circulation is not required, the connector and fitted blanking plug should be left un-
touched.
Hot water circulation may result in considerable heat loss within the piping system. A large propor-
tion of heat pump output may therefore be lost. To prevent heat loss, circulation and hot water
pipes must be insulated with at least 30mm of mineral wool or other type of pipe insulating materi-
al.
