3.1.3 Deployment Principles
Precautions
● Check cabinets comprehensively and handle problems immediately.
● Before installation, check that the environment meets requirements and check
whether reconstruction is needed for routing pipes and cables and
constructing ventilation pipes.
● Install the NetCol5000-A according to the design drawing and reserve space
for maintenance. Ensure that a minimum of 600 mm maintenance clearance
is reserved in front and rear of the indoor unit.
● The equipment room should have good heat insulation, and the walls and
oor should be protected against moisture.
● Take care to prevent the components and cables from damage.
● Check that the area, height, and ground bearing capacity of the installation
position meet requirements.
● To ensure good ventilation, do not place the indoor unit in the corner of a
room or at the end of a long-and-narrow room.
● During the NetCol5000-A operation, all doors and windows of the equipment
room should be closed to reduce the additional load of the NetCol5000-A.
● Take appropriate thermal insulation and antifreeze measures for outdoor
water pipes to avoid poor drainage and
insucient water supply caused by
freezing.
Installation Layout Principles
Layout principles for installing the NetCol5000-A are as follows:
● If the outdoor unit is placed higher than the indoor unit, the maximum
vertical distance between them is 20 m. To ensure the NetCol5000-A
reliability, make an oil trap every 5 m to 6 m along pipes in the vertical
direction. For the
specications for oil traps and inverted traps, see 3.1.2.3
Pipe Components.
● If the indoor unit is placed higher than the outdoor unit, the maximum
vertical distance between them is 5 m.
● When calculating the height dierence, the compressor base is regarded as the
baseline for the indoor unit.
● The inverted trap should be higher than the top copper pipe of the condenser.
● In the gure, is a sign of a tilt, indicating that the scale of the
pipe tilting is at least 1:200. The pipe tilting direction should be consistent with
the hypotenuse of the right triangle.
● If the indoor unit is placed higher than or equal to the outdoor unit, inverted
traps or oil traps are not needed.
