Please check that the following documents have been supplied with the unit:
Before starting
- Installation instructions (this manual)
- Operating instructions for CTS 602 controls
- Wiring diagram
Should you have any questions on how to operate the system, contact your nearest Nilan dealer,
who you can find at
Compact S is a heat recovery ventilation system with a capacity of up to 330m
nal counter pressure. The energy of the exhaust air is transferred via a heat pump t o a 180litres
hot water tank as first priority and to the inlet air as second priority.
The system can be equipped with G4 duct filter. Other optional extras are also available, including
hygrostat and pollen filter unit.
The system is operated via CTS 602 c ontrols offering a wide range of functions, including menubased operation, weekly progr amming, timed filter alarm, fan speed adjustment, et c. The CTS 602
controls are described in a separate manual supplied together with the system.
For details of spare parts and accessories under Figure 25 “accessories”
Compact S 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.
Note: The water tank must be filled with water before the unit start up.

The system is supplied with a 1 m test cable for t he CT S 602 control panel. The control panel must

The CTS 602 control panel should be inst alled in a dry, frost-free location. A temperature sensor
built into the control panel prevents further cooling of the building should the primary heating system fail by switching the ventilation system off if control panel temperature falls below a preset
level.

from the Compact S front panel.
When lifting the unit with straps it is impor tant that the straps has an angle of maximum
count. There should be a minimum clearance of 602
45°C off perpendicular.

In order to prevent ice formation, it may be neces sary to equip the condensation outlet
with a heating cable where frost is possible Protecting the condensat ion outlet from frost

Condensation drain/water trap
Compact S 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

Supplementary heating element DHW
The hot water tank has a supplementary heating element of 1,5kW. The heating element can be
activated and de-activated via the CTS 602 control, see the “Hotwater” menu.
The temperature, at which the heating element should be active (T11), can be set in the “Hotwater”

he ducting must be insulated. Sometimes, standard loft insulation can be used for the purpose.
T
All ducting should be insulated with 100mm mineral wool to prevent heat loss and condensation.
Such insulation requirements also apply to soundproofed flex tubing. It is recommended that two
layers of 50mm insulating material be used. If ducting is installed in an unheated room, it is inadvisable to switch the system off for prolonged periods as air from heated rooms will rise into the
ducting and condensate, thus possibly causing moisture problems.

T
he discharge duct leads the exhaust air (from which the system has recovered the energy it con-
material
tained) to the outside through the roof or outer wall. It is important that the roof stack or wall grille
has at least the same area as the duct immediately ahead of the stack or grille. Any contraction will
cause unnecessary pressure drop, which may reduce ventilation capacity.
Holes for inlet and exhaust valves should be cut to fit the frame of the valve concerned. Secure the
valve frame in position using screws and then attach the valve. Wher e the valves should be positioned depends on room design and use. It is, for example, inadvisable to install inlet valves
immediately above where people usually sit as inlet air may sometimes be perceived as a draught.

The datalog interval is set via the menu SERVICE - DATALOG INTV at between 1 and 120
minutes.
If 0 / OFF is selected, logging is not periodical, but only on events and alarms.
• Temperatures are logged in Celsius, in whole degrees, in order to minimise the log file size.
• The status of digital inputs and outputs is combined in two shared log variables: ”Din” and
”Dout”.

Fault finding
If problems arise during operation, please check the following before calling the service centre.
Check whether the alarm LED on the front of the CT S 602 control panel is flashing. If so, investi-
gate the cause of the alarm and remedy the fault. If necessary, contact your local service centre.
For details of alarms and how to reset them, please refer to the operating instructions for the CTS
602 controls.
- Compact S is operating but with reduced output.
Check that sufficient air is being supplied to Compact S. Check f ilters for excessive dir t accumulation. Check that valves are sufficiently open. In 98% of cases, the fault is caused by
clogged filters. If necessary, increase the ventilation step. Any dampers to the open air
should be shut at outdoor temperatures lower than 6°C.
- Compact S is operating but there is no hot water.
Check whether the tank has been emptied of hot water. If the system is equipped with a
circulation pump but the circulation circuit has not been insulated, considerable heat loss
may result, significantly reducing Compact S capacity.
Has the required water temperature (T12) been set correctly in the CTS controls? Usually,
water temperature should be set to between 45 and 55°C. Please refer t o the CTS 602 operating instructions for details on checking and setting water temperature.
Is the air supplied too cold or the quantity supplied too low? Check filters and valves. Check
whether duct insulation is sufficient and complete.
- Compact S is not operating.
Check whether a fuse has blown. Check whether the hot water safet y thermostat has cut
out. If it has, press the button and the thermostat will cut in again once the water temper ature has dropped 10-15°C. If the thermostat continues to cut out, contact your local service
centre.

Maintenance
At least every 3 months:
The filters should be cleaned and renewed when needed. Usually the filter s need to be renewed
once every 3 month. The filter guard in the CTS 602 control can be used in order to make sure that
the filters are checked. The filters can be cleaned by vacuuming or shaking them.
Figur 23: Air Filter change
Changing filters:
1. Loosen screws
2. Remove the filter hatch
3. Pull out the two filter frames for change/vacuuming
Subject to alterations Page 29 of 33
Once a year:
- The sacrificial anode must be checked to ensure that monitoring of the anode is intact.
o The wire “yellow/green” is dismantled at the anode. This produces the “ALARM 70”
(LED flashing)
o The wire “yellow/green” is reassembled at the anode. “ALARM 70” disappears (LED
not flashing)
The hot-water tank can corrode if the anode is left unchanged.
- The intake should be inspected and any uncleanness should be removed.
- The evaporator should be inspected and cleaned.
- It should be checked that the condensate has free passage through the water seal and the
condensation drain.
- The safety switch for the hot water tank should be controlled.
- It is recommended to take out a subscription for service.

Energy saving
- The auxiliary heating element should be cut off and only be used at very large hot-water
demands. Please see CTS 602 directions
- The ventilation speed should not be set higher than necessary.
- Avoid hot-water circulation.
- Spread out the bathing times as the Compact S needs 6-7 hours to heat the 180L water.
- Insulate the ducting as prescribed.
- Do not cool during winter time.
