INSTALLATION PROCEDURE
Mounting the outdoor unit
When installing the outdoor unit, please refer to "Installation
guidelines" on page 3 to select an appropriate location.
1 Check the strength and level of the installation ground so that
the unit will not cause any operating vibration or noise after
installation.
2 Prepare 4 sets of M8 or M10 foundation bolts, nuts and washers
each (field supply).
3 Fix the unit securely by means of the foundation bolts in
accordance with the foundation drawing.
It is best to screw in the foundation bolts until their length
remains 20 mm above the foundation surface.
Drain work
Assure that drain water coming from the outdoor unit during heating
operation and defrost operation can be properly evacuated.
■ Install the unit on a base that can assure a proper drainage in
order to avoid ice accumulation.
■ A drain channel can be foreseen under the unit. Be sure that
drain water in this drain channel does not freeze causing
blockage by ice accumulation.
■ Avoid drain water flowing over the footpath, so that in case of
ambient freezing temperatures the footpath does not become
slippery.
Flaring the pipe end
To flare each pipe end, follow the procedure below:
1 Cut the pipe end with a pipe cutter.
2 Remove burrs with the cut surface facing downward so that the
chips do not enter the pipe.
3 Remove the flare nut from the stop valve and put the flare nut on
the pipe.
4 Flare the pipe. Set exactly at the position shown below.
1 Wrap the insulation pipe with finishing tape from bottom to top.
2 Service cover
3 Stop valve cover
4 250 mm from wall. Allow space for piping and electrical servicing.
5 If there is danger of the unit falling or overturning, fix the unit with
foundation bolts, or with wire or other means.
6 Distance from the outer side of the stop valve cover
7 If the location does not have good drainage, place the unit on
block bases. Adjust foot height until the unit is levelled. Failure to
do so may result in water leakage or accumulation.
