10 | Maintenance 4.3 To change 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. Open and remove the side cover.
Maintenance | 4.4 To clean the heat exchanger Danger • Make sure that the Mains supply to the unit is disconnected before performing any maintenance or electrical work! Warning • 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. Even if the required maintenance is carried out, dust will build up in the exchanger block.
12 | Maintenance The motor bearings are life time lubricated and maintenance free. Even if the required maintenance, such as changing of filters is carried out, dust and grease may slowly build up inside 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.
Maintenance | 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.
14 | Maintenance Temporary belt repair solution 1. Stop the unit by disconnecting the mains. Remove the cover of the unit. Remove the heat exchanger cover. 2. Use tape to attach the drive belt to the rotating heat exchanger, and rotate the exchanger by hand to get hold of the drive belt. 3. Remove the tape and put the ”empty” end on to the nipple. Press the ends firmly towards each other and tighten the nipple. 4. Pull the drive belt on to the belt pulley and rotate the exchanger by hand.
Troubleshooting | 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 system (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.
16 | Electrical data 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. 6 Electrical data Fans 70 W Total power consumption 83 W Fuse 10 A Voltage 230V 1~, 50Hz 7 Disposal and recycling This product is compliant with the European WEEE Directive and related national waste legislation.
