9.3 Installation of the Pipe Work

9.3.1 Correct Removal of Condensate Water

Warning!

Danger of breakdowns or malfunction. Danger of
condensed water leakage.
In

order to ensure that the unit drains correctly
take the recommendations described in this
section into account.

Methods for the removal of the condensed water which
is generated in the indoor unit:

- Condensed water can be allowed to drain naturally
using the natural fall of the condensed water pipe to a
suitable drain point. In order for it to be aesthetically
pleasing, use a solid pipework or trunking to cover the
pipework.

- Alternative hidden installation solutions also exist.

- For example, using an external pump for removal of
the condensed water, carrying the condensed water to
outside or to main drainage system.

- By natural fall to a collection point which is then
emptied using a pump which operates when the tank
is full, pumping the water to a suitable drain point.

Note!

This pump for condensed water is available as an
original Vaillant accessory with the
corresponding installation instructions (not
supplied in the UK).

Warning!

Danger of breakdowns or malfunction. Danger of
condensed water leakage.
T

o ensure that the unit drains properly using a
natural fall, the condensed water pipe must have
a an adequate fall from the indoor unit.

9.3.2 Handling the Refrigerant Pipes

Danger!

Danger of burns and eye injuries.
W

hen brazing or soldering pipe lines, use
suitable protection equipment (protective eye
protection and mask, welding gloves, flame
proof clothing)

.

Warning!

Danger of breakdowns or malfunction. Danger of
damage to refrigerant pipes through the use of
unsuitable materials.

- Use only pipes specifically intended for refrigeration
and R410A refrigerant.

Note!

In specialised dealers you will find refrigerant
pipes and the correct thermal insulation.

- Ensure that the refrigerant pipes are clean, dry and
polished

on the inside.

- The insulation of the pipes should be done using
specif

ic class ‘O’ insulation for cooling.

- Observe the minimum and maximum pipe lengths for
each model.

- Wherever possible avoid install excessive numbers of
bends in pipes. Do not over bend the pipe, keep the
radius as wide as possible to minimise load losses.

- When brazing pipes together, use only the correct
welding materials. During the brazing process a stream
of dry nitrogen should be run through the inside of the
pipes in order to avoid oxidisation forming inside the
pipe connection.

- Only cut the coolant pipes using propriety pipe cutters,
ensuring no swarf enters the pipe, and always keep the
pipe ends sealed wherever possible.

- Any flaring work should be performed meticulously in
order to create the correct connection and to avoid
subsequent losses of gas through the pipes.

- When reaming the cut pipe keep the pipe opening
directed downwards in order to prevent shavings from
getting into the pipes.

- Mount the joining tubes carefully, ensuring they
cannot become displaced during brazing. Ensure that
there is no strain on the pipe joints.

- Ensure that all pipework is insulated with the correct
grade of closed cell insulation and that all joints in the
insulation are sealed with insulation tape or glued.

- Carefully tighten the flaring connectors, centring the
flaring cone and the flanged nut. Applying excessive
force without correctly centring can damage the
thread and may allow water ingress into the
connection.

Split Type Installation Manual 11EN

9.3.3 Correct Installation of the Condensate Pipe
Work

Warning!

Danger of breakdowns or malfunction. Danger of
water leaks and blockages from unit and
pipework:

- Ensure that sufficient air breaks and traps are

provided to avoid water being retained within the
indoor unit. Otherwise, the condensed water could leak
from the indoor unit.

- For gravity drains ensure fall is sufficient, the pipework

is adequately supported and does not sag and bends
are of large radius to avoid blockages.

- If the water pipe is run outdoors, ensure that it is

insulated against freezing.

- If the condensed water pipe run through an un-heated

room, fit thermal insulation.

- Avoid installing the condensed water pipe with a rising

bend (see Figure 9.2).

Fig. 9.2 Avoid rising bends.

- If the drain is run to a tank or butt, avoid installing the

condensed water pipe with it free end submerged in
water (see Figure 9.3).

Fig. 9.3 Avoiding submerging the end.

- Do not allow the drain line to be crimped or flattened

which could reduce the flow of water from the indoor
unit (see Figure 9.4).

Fig. 9.4 Avoid kinking the pipe.

- For drain pipes run to ground level outside, install the
condensed water pipe in such a way that the distance
of its free end from the floor is at least 5 cm (see
Figure 9.5).

Fig. 9.5 Minimum distance from the floor.

Legend

H Minimum distance from the floor: 5 cm

- Install the condensed water pipe in such a way that its
free end is kept away from unpleasant odours, such as
from open drains, to ensure that they are not drawn
back into the unit (see Figure 9.6).

Fig. 9.6 Avoids unpleasant odours.

Installation of the indoor unit 9

Split Type Installation Manual12

9.3.4 Making Holes for the Pipes

• Case A: Pipework exiting from the rear of the unit.
In

this case, a suitable hole must be made in the wall

behind the unit (see Figure 9.1).

• Drill a hole in accordance with the diameter and

position as indicated in Figure 9.1, ensure the hole
is slightly descending to the outside to allow for a
fall in the drain line.

Fig. 9.1 Dimensions of the hole for the piping.

• Case B: Running the pipework out of either side or the
bottom of the unit.
In

this case holes do not have to made in the wall
since the indoor unit body has knock outs which can
be opened to allow the pipes to exit the unit: choose
the most convenient one for the desired outlet
position (see Figure 9.7).

•

Carefully break the knock out in the casing using pliers.

• If installing the rear exiting piping:

• Place the seal ring supplied for the hole in the piping
and insert the coolant pipes with the condensed
water pipe through the hole.

• Remember to seal the hole inside and out properly
after installing the pipes.

• Carefully bend the installation pipe in the right
direction, taking care not to overbend or kink the pipe.

Warning!

Danger of breakdowns or malfunction. Danger of
damage to the coolant pipes.
B

end the pipe carefully to prevent kinking or

breaks.

• There should be sufficient pipe tails on the indoor unit
to go through the wall width. If this is not the case
connect further lengths of pipe as required. Carefully
feed the pipe tails through the holes together with the
condensate pipework and interconnecting electrical
cable.

• Hang the indoor unit on the top edge of the
mounting plate.

• Tilt the lower part of the indoor unit forwards and
insert an auxiliary tool (e.g. a piece of wood) between
the mounting plate and the unit (see Figure 9.8) to
allow access to the unit connections.

Fig. 9.8 Assembling the indoor unit.

• Connect the coolant pipes from the outdoor unit and
the condensed water hose to the installation drain.

• Insulate the coolant piping and joints correctly and
separately. To do so, cover any possible cuts with
masking tape or insulate any bare coolant piping with
the corresponding insulation material suitable for air
conditioning installations (for connection of the
electrical wiring see section 11).

10.2 Planning the Refrigerant Return

The refrigerant circuit contains a special oil to lubricate
the outdoor unit compressor. To assist the return of the
oil to the compressor the following is recommended:

- that the indoor unit is located higher than the outdoor
unit and,

- that the suction pipe (the thickest one) is assembled
with a gentle slope towards the compressor.

If the outdoor unit is mounted higher than the indoor
unit, the suction pipe must be mounted in a vertical
position. At heights exceeding 7.5 m (where this is
permissible):

• Additional oil traps must be installed at each 7.5M
interval

10.3 Connection of the Refrigerant Pipes

Note!

Installation is easier if the gas suction pipe is
connected up first. The suction pipe is the
thickest one.

• Mount the outdoor unit in the required position.

• Remove the flare nuts and bonnets from the shut off
in the outdoor unit.

• Carefully bend the installed pipe towards the outdoor
unit.

• Cut the pipes, leaving enough extra piping hanging
over to enable the unit to be connected at the outdoor
unit joins.

• Flare the refrigerant pipe after first placing the flare
nut on the pipe.

• Join the refrigerant pipes to the corresponding
outdoor unit connection.

• Insulate the refrigerant piping correctly and
separately. To do so, cover any joins in the insulation
with masking tape or insulate any bare coolant piping
with the corresponding insulation material suitable for
air conditioning.

12 Preparation for Use

This consists of the following steps:

• Checking for Leaks.

• Evacuation of the installation.

• Start up.

• Troubleshooting.

12.1 Checking for leaks

Fig. 12.1 Checking for leaks in the installation.

Legend

1 Suction valve (gas)
2 Return valve (liquid)
3 Service manifold
4 Non-return valve
5 Gauge lines
6 Nitrogen cylinder

• Connect a service manifold set to the service port on
the gas line stop valve of the outdoor unit.

• Connect a nitrogen cylinder to the charging hose of
the refrigerant gauges.

• Carefully open the valves on the service manifold to
allow the nitrogen to enter the installation. Do not
open the service valve on the outdoor unit as this will
release the pre-charged refrigerant from the outdoor
unit.

• In the event of using R-410A coolant set it to 40

bar(g) of pressure, for 10/20 min.

• Check that all the connections and joints are gastight.
If any leaks are found, repair and start the process
again from the beginning.

• On satisfactory completion of the test, close all the
valves on the combined meter and remove the
nitrogen cylinder.

• Release the pressure from the system by slowly
opening the valves on the service manifold.

• Do not continue to the next step until the pressure
test has been successfully completed.

According to Regulation 842/2006/EC, the complete
refrigerant circuit must be periodically checked for
leakage. Take the necessary actions to ensure these
tests are performed and the results correctly logged into
the maintenance record of the machine. The leakage
test must be done with the following frequency:

• Systems with less than 3 kg of refrigerant => periodic
leakage test not needed

• Systems with 3 kg or more of refrigerant => at least
once every 12 months

• Systems with 30 kg or more of refrigerant => at least
once every 6 months

• Systems with 300 kg or more of refrigerant => at least
once every 3 months

12.2 Evacuating the Installation

• Connect a vacuum pump to the charging connection of
the service manifold.

• Ensure that the the service manifold valves are closed.

• Turn the vacuum pump on and open the service
manifold shut off valve to open the system to the
vacuum pump

• Ensure that all other valves are closed.

• Leave the vacuum pump functioning for approximately
15 minutes (depending on the size of the installation)
to carry out the vacuum.

• Check the needle on the low pressure manometer: it
should indicate -0.1 MPa (-76 cmHg - >3 Torr). If the
service manifold gauge is not capable of measuring to
these pressures a separate Torr gauge should be fitted
in line to measure this pressure.

Preparation for Use 12

Split Type Installation Manual20

Fig. 12.3 Low pressure manometer reading with the low valve

open.

• Close the valves on the service manifold and
disconnect the vacuum pump.

• Check the manometer needle after approximately 10­15 minutes have elapsed: the pressure should not rise.
If it does rise, there are leaks in the circuit: repair
them (Check all joints and connections to the service
manifold carefully as the leak may be here).

• Close the valves on the service manifold and
disconnect the vacuum pump.

Warning!

Do not proceed to the next step until a
satisfactory evacuation of the installation has
been completed
