Monosplit “Wall” Personal Line Constant Speed - Section 5: Installation
Before supplying power to the system:
1.
Check the correspondance between wires and terminals on terminal blocks for connection between
Indoor Unit and Outdoor Unit.
2.
Check heat insulation of refrigerant pipings.
3.
Check if condensate and defrosting water drainage takes place properly. Check if a drain pipe
has been installed on Outdoor Unit’s base.
4. Check the correspondance of power supply as regards plate specifications required by system,
indicated on identifying plates of each Model.
5. Check if Outdoor Unit is fixed firmly to the supporting surface (possibly in masonry and in excellent
condition) and well leveled horizontally.
6.
Make sure that vacuum of refrigerant pipings and of Indoor Units’ refrigerant circuit has been
carried out. Also make sure that additional charge, if required, has been carried out too.
7.
Check if service valves on Outdoor Unit are completely open, both on gas and liquid sides.
8.
Check if there are no leakages of refrigerant gas near refrigerant connections, by using a high-

Is it possible to adjust room temperature according to your needs?
2.
Is it possible to change fan speed as it is required by your comfort needs?
3. Are there abnormal noises and/or excessive vibrations deriving from Indoor Unit and/or Outdoor
Unit?
4. Do outlet horizontal flap and vertical louvers reply properly to impulses sent by remote control,
and do they move properly in “SWING” and “AIR FLOW” modes?
5.
Does air supplied by Indoor Unit reach the installation environment uniformily?
6.
Does condensate water drip from Indoor Unit into the room?
7.
Does temperature difference between inlet and outlet ( D T) on Indoor Unit show a satisfactory
performance of system?
