Installation

5.2 Site requirements

1) Noise considerations

■ The unit is placed in the non-noise sensitive areas

■ The damping pad on the unit below (not supplied with the standard model damping pad, user-owned)

■ Install rubber shock absorbers on all water pipeline

■ Seal all wall gap at room

Note demanding applications should consult an acoustic engineer

2) Ground

Install it on a hard, easy deformation of mounting pads or a concrete foundation to withstand the total weight of

the living unit at runtime (including all piping, refrigerant, oil, water).

Referring operating weight parameter table. After placing a good unit, machine leader and level of assurance

in the width direction should 1/4 "(6.35mm) within. Haier company equipment problems as the basis of design

or construction caused inappropriate will not take any responsibility.

3) Shock absorbers

■ Provide rubber shock absorbers for the unit all the water pipes (Haier company standard models do not random

with shock absorbers, user-owned).

■ Use a exible tube connecting wire electrical lines.

■ Isolate all pipe hanger to ensure that they are not supported by the main structural beams of the building, so as

to avoid vibration transmitted live and work areas.

■ Ensure that the pipeline will not add additional pressure to the unit.

Be careful not to use metal tube shock absorbers, because the frequency range of plant operation, the damper

is ineffective.

4) Frost protection

Note

In the case of low ambient temperature in winter, overnight shutdown period, heat exchangers and water pipes

may freeze inside, causing damage to equipment and piping. To prevent freezing, never allow the unit off

(because the unit has an automatic antifreeze function), as well as possible icing must put all the water

discharge pipe; hot side 65 to increase drainage and air-conditioned sides need to water line installation valve,

care must be taken to be installed at the lowest point of the water circuit, if the drainage more difcult case, you

can use anti-freeze mixture of ethylene glycol or propylene glycol (ratio table below).
