Installation Of Outdoor Unit - Haier HBU-14CL03R1 Service Manual

5.4 Installation of outdoor unit

5.4.1 Selection of installation place
Place strong enough to support the unit and will not cause vibration and noise.
Place where discharged wind and noise do not cause a nuisance to the neighbors.
Place where is less affected by rain or direct sunlight and is sufficiently ventilated, or to install a shield.
Place with enough space for smooth air flow.
The unit shall not be installed on an unspecifised metal frame (e.g. theft guard net).
If the outdoor unit is installed close to a street, it shall be no less than 2.5m from the ground.
5.4.2 Fixing of the unit
Fix outdoor unit using M10 bolt to concrete floor horizontally.
If installed on the wall or on top of a roof, bracket should be fixed securely to resist earthquake or storms.
Use rubber pad during installation against unit vibration.
Install the unit so that the angle of inclination must be less than 3 degrees.

5.4.3 Air purging method: To use vacuum pump
For those models which adopt R407C refriengerant shall only use vacuum pump to
purg air.
1
Detach the service port's cap of 3-way valve, the valve rod's
cap for 2-way valve and 3-way's, connect the service port
into the projection of charge hose (low) for gaugemanifold.
Then connect the projection of charge hose (center) for
gaugemanifold into vacuum pump.
2
Open the handle at low in gaugemanifold, operate
vacuum pump. If the scale-moves of gause (low)
reach vacuum condition in a moment, check 1 again.
3
Vacuumize for over 15min. And check the level
gauge which should read -0.1 MPa (-76 cm Hg)
at low pressure side. After the completion of
vacuumizing, close the handle 'Lo' in gaugemanifold
and stop the operation of the vacuum pump.
Check the condition of the scale and hold it for
1-2min. If the scale-moves back in spite of
tightening, make flaring work again, the return
to the beginning of 3 .
