Haier AH1-070B Manual page 20

Install the lifting tools on the lifting bolts according to the instruction of the Fig.2
Be sure to follow the stipulations on products locally purchased to use nuts (M8 or M10 of 3 pieces for 4 positions)
and gaskets (M8 with the outer diameter of 24~28 mm and M10 with that of 30~34 mm of 2 pieces for 4 positions)
on the upper and lower sides of the lifting tools.
<Note>
Be sure that the product must be installed with the top surface (the oblique surface in the Fig.2) upward, or it will
not work well and increase the working noise.

6.5.1. Refrigerant pipe Installation
• Pipes between the outdoor unit and connection kit, selection of refrigerant branching suite, and the Pipe between
refrigerant branching suites and the indoor units, please refer to the installation instructions or equipment design
data attached to the outdoor unit.
• Before Installation, make sure the type of the refrigerant to be used is R410A. (If a refrigerant other than this type
is used, It cannot run properly)
• Please provide thermal insulation at the high-pressure gas pipe, suction gas pipe,, liquid pipe and oil equalizing
pipe (pipes for outdoor units in case of multi-split system) and the connections between these pipes. In the
absence of thermal insulation, liquid leakage and scalding may happen. Particularly when the high-pressure
gas pipe delivers indrawn air under full-refrigeration condition, it needs the same thermal insulation as does the
suction gas pipe. Besides, high-pressure gas pipe and suction gas pipe are to deliver high-pressure gas, thus
please provide thermal insulation material that can sustain temperature over 120 °C.
• Enhance the thermal insulation material based on the installation environment. The indicators are shown below.
For RH75%–80% at 30°C: over 15 mm thick.
For over 80% at 30°C: over 20 mm thick.
If not reinforced, the thermal insulation material surface is prone to condensation. Please refer to the equipment
design data for further details.
