It is necessary to use the sufficiently long stay bar so that the hoisting strap or chain will not touch the
unit, otherwise they may cause damage to the unit.
According to the instructions of the unit manual, please use all specified hoisting points to perform
hoisting.
As the unit's structure may change, unit's center of gravity shall be determined by the trial hoisting.
Use hoisting technique to keep the unit stable and horizontal.
During hoisting process, it is strictly forbidden to stand under the unit. Please keep away from the
position directly below the unit.
2.3. Selection for the Installation Position of the Unit
It cannot be installed in places with polluted air, such as the place which has flammable and explosive articles,
corrosive gases, salt fog and severe dust (such as coal ash and metal dust, etc.), etc.
The unit shall be installed in the area whose altitude is below 2000m. If it is more than this range, it may cause
damage to the unit or injury to the personnel. Please contact York's Special Maintenance Center if it is unavoidable
The unit can be installed on the ground or the suitable roof (unit without shell is forbidden to be installed in
the open air), or it can also be installed in the machine room. The ground surface is required to be flat, and it
shall have sufficient strength to support the operation weight of the unit.
Don't install the unit at the place which is relatively sensitive to the noise & vibration, or which has high
requirement for noise & vibration, in order to avoid the generation of resonance and echo between the unit and the
house.
For the installation position of the unit, please avoid the direct sunlight as far as possible, shall keep away from the
boiler flue and shall keep away from the air environment which may corrode the unit's components
The unit cannot be installed in the place which is easy to be blown by the strong wind
The unit cannot be installed in the place where the snow is easy to accumulate and off which the sundries can easily
fall.
The unit cannot be installed under the drainage pipeline
If the unit is located in a place accessible to unauthorized personnel, then the isolation safety measures, such as
setting guard rails, shall be taken. This can prevent man-made damage and accidental damage, and prevent the
control box from being opened and making the running electrical components exposed.
Unit's height shall not be the highest point of the building, and if so, it is necessary to install the lightning protection
device at the place higher than the unit
Adequate space shall be left around and above the unit for conducting routine maintenance work
The installation space shall be provided with sufficient natural ventilation hole to prevent the personnel's
suffocation caused by the leakage of the refrigerant
!
Caution: For special installation requirements, please consult with the construction contractor or architect
or other professionals.
2.4. Requirements for Unit's Installation Foundation/Installation Space
Installation Foundation
The unit shall be installed on the solid concrete or channel steel whose surface is flat and which is enough to
support its weight, and the concrete must be solid. Bolt's fixing hole shall be pre-buried, and it shall be fixed by the
bolt. In addition, the following requirements shall also be met:
The horizontal concrete foundation or steel frame shall be able to withstand the operation weight of the whole
equipment set and the weight of the maintenance personnel
When combining multiple modules, the concrete foundation of each module must have the same height, in
order to facilitate the laying of the water pipe path among the modules
Do not connect the unit's foundation to the building's foundation in order not to transfer the noise and vibration
Installing hole shall be arranged on unit's base, and it can be used for fixedly connecting the unit with the
foundation; The specification of the foundation bolt is shown in the unit's foundation drawing
The foundation shall be able to facilitate the operations, such as the maintenance for the unit
In order to ensure that the outdoor unit can be placed flat on the foundation, it must make sure that the flat
surface in which the outdoor unit locates is flat firstly, and then the outdoor unit can be placed, and you
should check whether the outdoor unit is horizontal or not after installation of the outdoor unit. The
inclination angle shall be less than 10°; for the one with shock absorbers, the level shall be checked after the
shock absorber is installed
Drainage channels shall be provided around the unit to ensure the smooth discharge of the rainwater or
condensed water; If there is no discharge channel, add a water tray at the bottom of the unit and lead it to the
appropriate place through pipeline; The drainage pipeline shall be capable of timely discharging rainwater and
the condensed water generated by the unit.
