3 Before starting Please check that the following documents have been supplied with the unit: - 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 P is a heat recovery ventilation system with a capacity of up to 330m 3 /h at 100Pa external 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 G4 duct filter. Other optional extras are also available, including hygrostat and pollen filter unit. The system is operated via CTS 602 controls offering a wide range of functions, including menubased operation, weekly programming, timed filter alarm, fan speed adjustment, etc. The CTS 602 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. Subject to alterations Page 3 of 29

4 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 CTS 602 control panel. The control panel must be connected to the CTS 602 controls using twisted pair cable type 2x2x0.25mm 2 (max. length 50m). The CTS 602 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 system fail by switching the ventilation system off if control panel temperature falls below a preset level.

5 Installing Compact P When installing the unit, it is important to take future service and maintenance into account. 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). Figur 2: Duct Connections 1.

6 Figur 3: Sketch of Compact P 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 adjoining 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. Subject to alterations Page 6 of 29

8 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. Subject to alterations Page 8 of 29

9 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 untouched. Hot water circulation may result in considerable heat loss within the piping system. A large proportion 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 material.

11 Duct connection Ducting and fittings with rubber seals of tightness class B are recommended. It is also advisable that all duct connections to Compact P be made with approx. 1m of soundproofed flex tube in order to dampen sound emission. Ducting should be cut to length using a hacksaw or angle grinder and laid in accordance with the design drawing. Ducting is usually either attached to rafter feet using perforated strip or suspended in fitting strip. Avoid pinching the ducting in any way and any unnecessary bends. The ducting must be insulated. Sometimes, standard loft insulation can be used for the purpose. 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. Loft insulation material Duct Granulate Figur 7: Insulation of ducting The discharge duct leads the exhaust air (from which the system has recovered the energy it contained) 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. Where 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. Subject to alterations Page 11 of 29

12 Supplementary heating element DHW The hot water tank has a supplementary heating element of 1,5kW.

26 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 CTS 602 control panel is flashing. If so, investigate 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 P is operating but with reduced output. Check that sufficient air is being supplied to Compact P. Check filters for excessive dirt 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 P 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 P 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 to 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 P is not operating. Check whether a fuse has blown. Check whether the hot water safety thermostat has cut out. If it has, press the button and the thermostat will cut in again once the water temperature has dropped C. If the thermostat continues to cut out, contact your local service centre. Subject to alterations Page 26 of 29

27 Maintenance At least every 3 months: The filters should be cleaned and renewed when needed. Usually the filters 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 20: Air Filter change Changing filters: 1. Loosen screws 2. Remove the filter hatch 3. Pull out the two filter frames for change/vacuuming Once a year: - The sacrificial anode should be inspected and renewed if it is much corroded. The hotwater 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.
