3. Mechanical installation

The installer is responsible for safely and securely fastening the unit to the wall.

Note: When lifting the unit, it is important to place a protective underlay, to avoid scratching the base plate. The underlay can consist of, e.g. thick cardboard or a similar material.

The mechanical installation involves

• Marking, drilling of holes for connecting ducts and mounting of wall frame

• Mounting of unit in wall frame

• Installation of pipes and grates through walls or over roof, depending on model

• Mounting of panels

Important: Before drilling holes in wall or roof, check that there is at least 0.5 m between the wall and the unit’s exhaust end. If the exhaust end is facing out towards glass panes, that distance must be greater. If these minimum distances are not observed, there is a risk of increased noise from the unit.

Simplified picture illustrating mounting of unit on wall frame.

CODUME Page 8

3.2 Mounting unit in wall frame

Start by finding the centre of the wall frame using a ruler.

The centre measurement for the wall frame is 62 cm. Mark the measurement.

Next mark the middle of the wall or the location you wish to place the centre of the unit.

Now line up the two marks. If you like, you can place the

wall frame all the way up to the ceiling. If you do this, there will be a 6 mm gap between the top of the unit and the wall.

Now that the wall frame is provisionally hung, you can mark holes for screws and the centre of supply and exhaust. The duct size is Ø200mm. The recommended hole diameter is Ø210-215 mm, so the pipes can be insulated subsequently.

Horizontally measure and mark distance down to centre of supply/exhaust, and mark centre in vertical direction.

CODUME Page 9

This clearly indicates the marking of the centre of the intake hole.

Note: The length of the two pipes depend of the wallthickness.

All necessary markings show.

Note: The holes for the pipes should have a downward start of 1-2%, to prevent hard rain from penetrating the unit.

Here, both holes have been drilled, and the wall frame is now securely fastened to the wall.

Note: The screw type used depends on the wall material.

Place the unit on a thick underlay, such as cardboard or the like, to prevent scratches in the base plate. It is important that the unit is stable on the lift.

Note: Remember to remove tape holding the discharge damper in the transport position.

The unit is on the underlay and is safely and securely placed on the lift.

In the picture on the right, the unit is raised and can now be adjusted to the two guide hooks placed on the wall frame.

CODUME Page 10

Make final adjustments to the unit to unable it to be pushed far enough over the hooks that it cannot fall back out again.

In the picture on the right, the unit is hanging from the two guide hooks.

At the bottom of the picture one of the adjustment screws shows.

Now, fasten the unit to the wall frame, using the two factory-supplied M8 bolts, one on each side.

To get the unit to hang properly relative to the wall, adjust it by screwing the two adjustment screws situated just over the base plate.

Use a no. 13 screw wrench.

The unit must hang horizontally; therefore, it is important to check and readjust.

3.3 Mounting pipes and grates

Mount two Ø200 mm pipes through the wall with a 1-2% outward slant. The length of the pipes is calculated based on the thickness of the wall.

Remember to remove tape holding the damper in the exhaust in transport position. Finally, mount Ø200 mm grates with slats pointing down. Remember to joint between grate and outer wall. It is important

that the penetrations not are twisted or forced onto the unit’s connecting pieces, to avoid an elevated noise level.

3.4 Connecting the water heating surface

The unit can be purchased complete with water heating surface (optional), motorised valve, automatic heatretaining thermostat and air escape valve internally mounted and threaded. The heating unit has been tested for leaks and undergone final inspection in accordance with DS 469.

Dimensioning of pipes, valves and connections to the unit must always be carried out by authorised personnel.

Connection

Lead the hot water connection through the cabinet on the right side or at the top to the connecting pieces placed inside the unit, behind the service cover. Connect the forward hot water connection to the connecting piece market FORWARD and the return to the connecting piece marked RETURN. See the below dimensioned sketch for further instructions regarding lead-through of the water connection.

Note: The regulating valve (3) requires clean unit water in order to function optimally, without disruptions from blockage in the valve. Airmaster A/S recommends that a dirt trap and continuous regulating valve be fitted in the hot water connection according to the below-mentioned simplified diagram.

Ventilation

Open water flow and aerate the system using the air release valve (4). After a short while the water flow should be silent, with no noise from air.

The aeration is carried out with fully open valves, dismounted heat-retaining thermostat (TV) and thermal motor

(TM).

Adjustment of motorised valve

The unit comes with regulating valve (3) type TRV-2S preset to 6 – fully open valve. The regulating valve is preset according to the diagram below, such that the prescribed flow is achieved with differential pressure of ∆H, which is available to the unit in nominal operating conditions.

Remember that the unit must be aerated and rinsed prior to adjustment.

It is important to preset the valve so the maximum water flow is not exceeded.

If the differential pressure over the regulating valve is greater than 30 kPa, you risk a flow noise from the valve.

Setting example: Water flow: 15 l/h

Desired drop in pressure: 10 kPa Setting value: 2,5

Presetting key for TRV-2S: Plumbing no. 403399-411

Calculation of heating needs

The heat requirement for heating air from temperature after heat recovery to the desired supply temperature is calculated at 20 °C and 101.3 kPa:

Q = 0.34 ⋅⋅⋅⋅ qv ⋅⋅⋅⋅ (IT – t) [ W ] where

air volume in m3/h IT desired supply temperature t = 15.9 °C temperature prior to post-heating surface

Conditions: - outdoor temperature –12 °C

- room temperature 22 °C

- temperature rate of efficiency 82%

Setting the heat-retaining valve

The heat-retaining valve (2) type RA-N 10 is factory-set to N, fully open valve. The valve is preset to 3.5. The setting zone of the sensor element (TV) type RA is factory-set to a min. of 1.5 to ensure a minimum heating surface

temperature of approx. 14°C, provided that hot water is available.

Frost-resistance

• The heat supply or water flow must never be interrupted/shut off in frosty weather

conditions, e.g. on weekends and during holiday periods.

• The flow temperature must never drop below 40 °°°°C in frosty weather conditions.

3.5 Connecting the electric heating surface

The unit comes complete with electric heating surface and safety thermostats internally installed and wired.

Note the greater current collection with electric heating surfaces (see the electrical installation section).

Safety functionalities of electric heating surface

The electric heating surface is protected against overheating in accordance with DS 447 thanks to two safety thermostats that disconnect the heating surface in case of overheating.

• One thermostat cuts out the heating surface at 70 °C and has an automatic reset

• The other thermostat cuts out the heating surface at 120 °C and has a manual reset

Furthermore, the unit is fitted with air volume monitoring

• which at air speeds of less than 0.3 m/s cuts out the heating surface and automatically re-connects it again when the air

speed is greater than 0.3 m/s.

4. Electrical installation
