6.1 Symbol Precautions
Symbol description
Dear user,
For the better understanding of this Manual and the proper operation of the chiller, the marks and symbols used in
this Manual are described as follows:
It is likely to cause death, serious injury and other severe accidents if the user fails
to do as required.
It is possible for severe accident to occur.
WARNING
CAUTION
WARNING
CAUTION
■Installation and maintenance must be carried out by professionals experienced in this type of unit in accordance
with applicable local codes and rules on installation and maintenance. We are not liable for any unit damage or
casualty due to non-conformance with this requirement.
■The power supply must be switched off prior to maintenance and relocation of the unit; otherwise, personal
injury or death may be caused by electric shock. Do not touch such hot components as compressor and exhaust
pipe directly.
■When the water system contains water, control the startup and shutdown of the water pump via the water pump
output point on the unit controller; otherwise, the anti-freezing protection of the unit will not work, causing the
freezing crack to the heat exchanger. If the unit is to idle for a long time in winter, drain the water from the water
system via the drain valve to prevent the freezing crack of the heat exchanger, the water pipe and other parts on
water side. Furthermore, the water pump shall be power off to avoid starting up against frost without water.
■To prevent the heat exchanger on water side from being frozen due to foreign matters entered, a self-contained
water lter must be installed on the water return pipe of the unit (specic installation position is shown in water
system diagram).
■Dregs and dirt in the water pipe network including lter and heat exchanger may seriously damage the heat
exchanger and water pipe. Installers and users must ensure the quality of chilled water, not use anti-icing
mixtures containing salt and prevent the entry of air into the water system, because the salt and air can oxidize
and corrode steel parts inside the heat exchanger.
■No unit is allowed to be installed near such places that are dirty, oily, salty, exposed to a large amount of sulfur
gas and where the unit parts may be subjected to corrosion, such as toilet vent, operation room vent and
sewage treatment equipment.
■If the unit is operated below 0°C, it must be installed at a place at least 300 mm above the ground, so as to
avoid
icing of unit base plate and to ensure the normal operation of the unit even though the snow reaches this height;
in addition, the unit shall be placed on a plane (with maximum deviation per meter of not more than 2 mm).

15
6.2 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).

6.3 Installation
■Drawing of Overall Dimension
■Reference Position of Base
1. The bearing capacity of base is designed as per the weight of unit during operation.
2. The base may be of U-steel (designed by users as per overall dimensions of the unit) or
concrete structure and shall have flat surface.
3. A 10-20 mm rubber shock pad shall be placed between the unit andthe base.
4. The unit and the base may be fastened with ø16 or ø18 anchor bolts.

Selection Installation Position
■For the better cooling (heating), the installation position of the chiller unit shall be selected as per the followings:
■The unit shall be installed at a place where the hot air exhausted by the unit is not sucked back, that exhausted
by other unit is not sucked and sufcient space is reserved for the unit maintenance.
■Exhaust and suction channels of the chiller unit shall be free of any barrier that will block the air ow.
■The unit is installed at a well ventilated place to improve the heat exchange.
■The installation position shall have enough strength to withstand the unit weight and the vibration
during operation.
■The unit shall not be installed at a place that is dirty, oily, salty and exposed to a large amount of sulfur gas.
■The chiller unit shall not be installed at such place where ammable gas may leak. Because the ammable gas
leaked and accumulated around the unit may lead to explosion.
■The chiller unit shall not be installed at such a place exposed to strong wind or typhoon or accumulated
rainwater and snow. If possible, auxiliary equipment for preventing rainwater, snow and direct sunshine may be
provided.
■The unit base shall be made of concrete or support. Full consideration must be given to oor strength, drainage
(water is drained from the unit during operation) and pipe and wire route in the base construction. If the base is
not strong enough, the unit may fall down, causing unit damage or personal injury.
■The chiller unit shall be rmly fastened with anchor bolts to prevent falling down due to earthquake or strong
wind In order to withstand strong wind and earthquake, the unit must be positioned properly and can not be
installed at such a place exposed to strong wind.
■Depending on installation conditions, vibration may be transferred to tted parts, and base plates and walls may
produce vibration and noise. Therefore, proper vibration protections
(e.g. setting shock pad, dumper bracket, etc.) shall be provided.
■Edges and corners must be positioned correctly. The improper installation may lead to instability, resulting in
bending of mounting feet. Any improper installation may cause the falling down of the unit, leading to
personal injury.
■The unit shall be positioned so as to minimize the impact on residences.
■Pre-installation Preparation
■Cargo inspection
All units are rmly bolted on wood trays, subject to ex-factory inspection and lled with accurate amount of
R410a refrigerant and refrigeration oil for the unit operation. Upon the receipt, you shall carefully inspect cargoes
for any damage during transport and conrm all ordered parts and accessories are delivered.
You shall inform delivery man of any damage immediately. And you shall inform problem to us other than
appearance damage immediately.
■Handling
You shall handle the unit by a forklift or crane. If a crane
is used, the top and side panel of the unit shall be protected
by appropriate spacers (as shown in the gure). During the
handling, the unit shall be kept horizontal and not be inclined
for more than 30°, and the unit damage due to violations shall
be avoided.
■Disassembly
Place the unit at a desired position, cut binding tapes, remove
the external crate, unscrew bolts and remove the wood base
from the unit bottom.
