Mounting Guide 5

1 Product description

DA 1800 CD ceiling inlet is an efficient and compact fresh air inlet for supplementary ventilation in vapour-per-

meable ceiling constructions. The inlet opens by slackening the string.

The ceiling inlet is made of injection-moulded ABS which is dirt-repellent and easy to clean. The inlet is insu-

lated with polystyrene in the inlet casing. The capacity is high with a max. output of 1800 m3/h at 10 Pa negative

pressure.

The inlet consists of 6 parts, arm for pull rod and string and arm for flap are mounted with screws, while pipe

holder for cooling pipe is clicked into place.

1.1 Principle of application

During hot periods with high ventilation require-

ments, a large volume of air can be directed

down into the animal zone.

During cold periods, the air is directed through

the ceiling.

401361 DA 1800 ceiling inlet CD

DA 1800 ceiling inlet is a universal air inlet, which brings fresh air into the

house through the attic. DA 1800 is insulated and available as standard

with a regulation set.

The inlet funnel must be ordered separately.

2.1 Accessories

401323 DA 1500/1800 inlet funnel - short

401337 DA 1540/1800 inlet funnel - long

The purpose of using the inlet funnel is partly to increase the incorporation

height of the inlet to a total of 250/400 mm from the lower edge of the ceil-

ing to the upper edge of the inlet funnel. Furthermore, the aerodynamic de-

sign of the inlet funnel ensures optimized inflow conditions which reduce the

pressure loss and thus the energy loss at a given amount of air. This re-

duces the necessary negative pressure in the house.

Use one unit per inlet.

401364 DA 1540/1800 insert module

DA 1540/1800 insert module is used to reduce the air capacity in a single

pen, often at the end of an inlet row. The insert module can be used with

the inlet funnel.

The insert module reduces the air capacity by 50 %.

Use one unit per inlet.

437482 DA 1500/1800 pipe holder

For DA 1540/1800 ceiling inlet a special pipe hanger has been developed,

which can be used for securing high pressure cooling pipes from SKOV A/

S, if high pressure cooling is installed. The pipe holder can only be used

when the ceiling pitch is 0°.

Use one unit per inlet.

If the distance between the inlets exceeds approx. 1.5 m supplement the in-

let by item no. 437480 DA 1540/1800 pipe holder with adapter.

If the length of the cooling piping exceeds 40 m, the pressure impact from

the start/stop of pump may cause breakage of the rather long pipe holder.

Mounting Guide 7

437480 DA 1540/1800 pipe holder with adapter - 0.5 m

Used where extra support of the cooling pipe is required. Height approx. 49

cm which means that it is suited for the 437482 pipe holder for DA

1540/1800. The pipe holder can only be used when the ceiling pitch is 0°.

Mount it directly on the ceiling with the two screws supplied.

In Denmark one unit per 1.2 m free-hanging cooling pipe is used - corre-

sponding to normal lath distance.

If the length of the cooling piping exceeds 40 m, the pressure impact from

the start/stop of pump may cause breakage of the rather long pipe holder.

401335 DA 1500/1800 holder for pullrod

Is applied if the distance between the inlets exceeds 2m.

Mounted vertically with two screws in the ceiling.

3.2 Placement in ceiling

The inlet should not to be placed over trough as dripping may occur.

Make sure that there is free space for pull rod and inlet flap.

The insulation material must fit tightly around the inlet.

Take care of various obstacles such as pipes, light fittings, electric cables, etc.

Here, the inlet is shown from above.

Cutout dimension 500 mm x 395 mm.

Make sure that there is room for the outer dimensions of

the inlet, see technical data.

Take care of various obstacles such as pipes, light fit-

tings, electric cables, etc.

Adapt a template of cardboard or a wooden board with

the dimensions 500 × 395mm.

Mark the selected spot and cut out.

Take care of electric cables in the ceiling, if any.

3.3 Preassembly

Mount arm for flap and arm for pull rod and lock the inlet

flap by means of the string.

Place the four screws in the corners.

10 Mounting Guide

3.4 Mounting lengthwise of boarding

With this kind of mounting, the tolerances are small, so

be careful not to damage the insulation on the sides of

the inlet.

Lay out insulation material.

Place the inlet funnel as shown.

3.5 Mounting across boarding

Place an extra board as shown here.

Lift the inlet into place and fasten the inlet with four

screws.

Lay out insulation material.

Place the inlet funnel as shown.

It is important that the inlet flap closes tightly.

Adjust misalignments by tightening/slackening the four mounting screws.

3.6 Mounting the string

Mount clips with string on the pull rod.

Mount string with lock for piano wire on the wire.

Mounting Guide 11

3.7 Mounting on sloping surfaces

In some cases, sloping surfaces/ceilings make con-

densed water which runs into the flap.

Drill two Ø 2.5 mm holes in the flap to ensure that the

flap is drained by this mounting method.

4 Maintenance instructions

TheDA 1800 does not require special maintenance. Periodically, string and spring are checked for wear.

The product may be cleaned by a high-pressure cleaner without using:

• solvents

• corrosive/caustic agents

4.1 Recycling/Disposal

Products suitable for recycling are marked with a pictogram.

It must be possible for customers to deliver the products to local collection sites/recycling stations in accordance

with local instructions. The recycling station will then arrange for further transport to a certified plant for reuse,

recovery and recycling.
