GB Maintenance |11
Note:
Do not forget to tighten screws back after the maintenance!
4.3 Changing filters
The filters cannot be cleaned and must be changed as necessary. This is normally done 1–2 times per year depending
on the air pollution at the installation site.
It is very important to change filters regularly for performance and energy efficiency of the unit.
When it’s time to change the filters an alarm is shown on
the control panel display. When this occurs do the
following:
1. Stop the unit by disconnecting the mains.
2. Remove the filter cover plates.
3. Pull out the filters towards you. Some force may be
needed.
4. Insert the new filters. Make sure that the correct filter
types are inserted.
5. Remount and fasten the filter cover plates and connect
the unit to mains.
6. Reset the filter time. See chapter 4.3.1
4.3.1 Resetting the Filter Change Time
Once filter is changed, it is necessary to reset filter time. Go to Filter menu

electrical work!
Warning
Risk of personal injury! The heat exchanger weighs about 10 kg. There is a risk that the heat exchanger falls
out of the unit.
If the unit is ceiling mounted with side cover facing downwards, the heat exchanger may fall out if not
secured.
Make sure that small children are not beneath the unit when the heat exchanger is removed!
Caution
• Beware of sharp edges during mounting and maintenance. Use protective gloves.
212963 | v01_1.8.0

12 |Maintenance GB
Even if the required maintenance is carried out, dust will
build up in the exchanger block. It is therefore of vital im-
portance for the upkeep of a high efficiency that the ex-
changer block is removed from the unit and cleaned
periodically as described below. Clean the heat exchanger
at least every 3 years or when required.
1. Stop the unit by disconnecting the mains.
2. Open the side cover. See chapter 4.2.
3. Disconnect the rotor power supply and the rotor sensor.
The cables are found beside the rotor at the back.
4. Take out the heat exchanger package.
5. Gently vacuum the heat exchanger.
Warning
Ensure the rotor motor is not exposed to
moisture
6. Remount the rotor. Don’t forget to reconnect the rotor
power and sensor cables.
7. Close and fasten the side cover and connect the unit to
mains.
4.5 Check and Clean Fans
Danger
• Make sure that the mains supply to the unit is disconnected before performing any maintenance or
electrical work!
Warning
• Risk of injury due to rotating parts that have not come to a complete standstill after mains supply to the
unit have been disconnected.
Warning
• Beware of sharp edges during mounting and maintenance. Use protective gloves.
The motor bearings are life time lubricated and mainte-
nance free.
Even if the required maintenance, such as changing of fil-
ters is carried out, dust and grease may slowly build up in-
side the fans. This will reduce the efficiency.
1. Disconnect the fan power cables. The cables are found
beside the fans.
2. Remove knobs that hold fans in place.
3. Pull out the fans towards you. Some force may be
needed.
4. Clean the fans with a cloth or a soft brush. Do not use
water. White spirit can be used to remove obstinate
deposits.
Allow the fans to dry properly before remounting.
5. Remount the fans. Don’t forget to reconnect the fan
power cables.
6. Close and fasten the side cover and connect the unit to
mains.

4.6 Replacing rotor drive belt
Danger
• Make sure that the mains supply to the unit is disconnected before performing any maintenance or
electrical work!
Warning
• Risk of personal injury! The heat exchanger weighs about 10 kg. There is a risk that the heat exchanger
falls out of the unit.
• Make sure that small children are not beneath the unit when the heat exchanger is removed!
If the alarm Rotor guard is raised the rotor drive belt may be damaged or broken, see chapter 3.6.
SAVE VSR 150/B units are delivered with two welded drive belts (1) — one mounted and one as extra if replacement is
required. Spare belt is enclosed in a plastic pocket with manuals.
4.6.1 Temporary belt repair solution
In case both welded belts break it is possible to use joint nipple as a temporarily quick repair solution until the welded
belt can be replaced with a new one. Depending of how the unit is installed, it may be not necessary to remove the
heat exchanger package in order to temporary repair a broken drive belt if the belt pulley can be accessed.
4.7 Duct System Maintenance
4.7.1 Cleaning extract louvres and supply air diffusers
The system supplies fresh air to your home and extracts the used indoor air via the duct system and diffusers/louvres.
Diffusers and louvres are mounted in ceilings/walls in bedrooms, living room, wet rooms, WC etc. Remove diffusers
and louvres and wash in hot soapy water as required (diffusers/louvres must not be exchanged). Cleaning of diffusers/
louvres can be done as necessary.
4.7.2 Checking the outdoor air intake
Leaves and pollution could plug up the air intake grille and reduce the capacity. Check the air intake grille, and clean as
necessary. It is recommended to do this at least twice a year.
212963 | v01_1.8.0

14 | Troubleshooting GB
4.7.3 Checking the roof cowl (if fitted)
The roof cowl (if fitted) connected to the exhaust air duct needs to be checked at least twice a year and cleaned if
necessary.
4.7.4 Checking and cleaning the duct system
Dust and grease deposits may build up in the duct system, even if required maintenance such as changing of filters is
being carried out. This will reduce the efficiency of the installation.
The duct runs should therefore be cleaned/changed when necessary. Steel ducts can be cleaned by pulling a brush
soaked in hot soapy water through the duct via diffuser/louvre openings or special inspection hatches in the duct sys-
tem (if fitted).
It is recommended to do this every 5 years and is normally carried out by authorized companies specialized in this area.
5 Troubleshooting
If problems should occur, please check the items below before calling your service representative.
Fans do not start
1. Check the control panel for alarms.
2. Check that all fuses and fast couplings are connected (main power supply and fast couplings for supply and extract
air fans).
3. Check the week schedule. Fans may be set to OFF in the Schedule airflow settings menu.
Reduced airflow
1. Check the control panel for alarms. Some alarms can reduce the airflow to LOW if active.
2. The unit could be in defrost mode. This reduces the fan speed and in some cases shuts down the supply air fan com-
pletely during the defrosting cycle. The fans go back to normal after defrosting. There should be a defrosting function
icon visible on the home screen if defrosting is active.
3. Speed of fans is linearly reduced when the outdoor air temperature is below 0°C and an outdoor airflow compensa-
tion function is enabled.
4. Check if temporary user mode that reduces airflow is not activated, for example Away,Holiday, etc. Also check dig-
ital inputs Central Vacuum Cleaner and Cooker Hood.
5. Check the airflow settings in the control panel.
6. Check week schedule settings (chapter 3.5).
7. Check filters. Is change of filters required?
8. Check diffusers/louvres. Is cleaning of diffusers/louvres required?
9. Check fans and heat exchange block. Is cleaning required?
10.Check if the buildings air intake and roof unit (exhaust) have been clogged.
11.Check visible duct runs for damage and/or build up of dust/pollution.
12.Check diffuser/louvre openings.
The unit cannot be controlled (control functions are stuck
1. Reset control functions by disconnecting mains power for at least 10 seconds.
2. Check the modular contact connection between the control panel and the main printed circuit board.
Low supply air temperature
1. Check the control panel for alarms.
2. Check the active user functions on the control panel if defrosting function is running.
3. Check set supply air temperature on the control panel.
4. Check if ECO mode is activated on the control panel (it is a power saving function and prevents the heater from
activating).
5. Check if user modes Holiday,Away or Crowded are activated on the control panel or via a hardwired switch.
6. Check the analogue inputs in the service menu to verify that the temperature sensors are functioning correctly.
7. In case of installed electrical/other re-heater battery: Check if the overheat protection thermostat is still active. If
necessary, reset by pressing the red button on the front plate of the electrical re-heater.
212963 | v01_1.8.0

GB Electrical data | 15
8. Check if the extract filter must be changed.
9. Check if the unit has a re-heater battery connected. At very cold outdoor conditions an electrical or water heating
battery might be necessary. A re-heater battery can be acquired as an accessory.
Noise/vibrations
1. Clean fan impellers.
2. Check that the screws holding the fans are tightened.
3. Check that the anti vibration lists are fitted to the mounting bracket and to the back of the unit.
4. Check that the rotor belt is not slipping if the unit has rotating heat exchanger.
