Outdoor Unit Installation Requirements

Precautions

• Ensure that the air intake section and air exhaust section of the condenser are unblocked. Install the outdoor unit in clean areas that are away from residential areas.
• Wrap thermal insulation layers for pipes connecting the indoor unit and outdoor unit.
• Do not hold the copper pipe or electric control box to transport the outdoor unit, and keep the fins intact.
• Route in pipes from the top and out from the bottom when connecting condenser pipes.
• The horizontal or vertical error should not be more than ±5° when the outdoor unit is installed horizontally or vertically. When the outdoor unit is vertically installed, the electric control box and its waterproof connector cannot face upward. The following figure shows the installation method mode.
  Figure 4-4 Installation modes (for NetCol500-A060)
  

Special Environmental Requirements

• Monsoon: If you install the outdoor unit vertically, ensure that the directions of air flowing into and out of the fan are not opposite to the monsoon direction.
• Direct sunlight: In high-temperature areas, avoid exposing the outdoor unit to direct sunlight.
• Wind and sand: Prevent sand from entering the condenser in deserts and windy and sandy areas.
• Catkins season: Prevent catkins from entering the condenser and clean up catkins at the air intake and exhaust vents.

Space Requirements

The NetCol500 outdoor units can be installed horizontally, vertically, or compactly. Figure 4-5, Figure 4-6, and Figure 4-7 show the horizontal and vertical installation. Figure 4-8 and Figure 4-9 show the compact outdoor unit installation requirements.

• The shaded parts in the figures are obstacles. The distances marked are the minimum distances required between an outdoor unit and obstacles.
• The horizontal installation and vertical installation take NetCol500-A080 and NetCol500-A060 as examples.

Horizontal and vertical installation scenarios

Figure 4-5 Space requirements for horizontal installation (unit: mm)

Figure 4-6 Space requirements for vertical installation (unit: mm)

Figure 4-7 Top view of the horizontal installation space for an outdoor unit with a low-temperature component (unit: mm)

1. The low temperature component must be within 2 m from the outdoor unit.
2. When the outdoor unit is vertically installed, do not place the low temperature component at the air outlet.
3. When the outdoor unit is horizontally installed, the outdoor unit and low temperature component must be placed on bases or concrete platforms of the same height. When the outdoor unit is vertically installed, the outdoor unit can be 1.5 m higher than the low temperature component at most and cannot be lower than the low temperature component.

Compact installation scenario

If the space does not meet the requirements of the recommended layout, you can use any of the following layouts (applicable only to NetCol500-A060 and NetCol500-A120). However, the cooling capacity of indoor units will be reduced. Exercise caution when deciding to select the non-recommended layouts.

Figure 4-8 Top view of compact installation if the quantity is ≤ 12 (NetCol500-A060)

Figure 4-9 Top view of compact installation if the quantity is > 12 (NetCol500-A060)

If necessary, you can use a base to increase the height for compact installation, the dimensions of the raised base can be obtained based on the BOM code. Take the NetCol500-A060 as an example.

• When the quantity is 12 or less, if the wall height is 0 mm, the base height is 0 mm. If the wall height is 1000 mm or lower, the base height is 500 mm or higher.
• When the quantity is more than 12, if the wall height is 0 mm, the base height is 500 mm or higher. If the wall height is 1000 mm or lower, the base height is 1000 mm or higher.

Figure 4-10 Top view of compact installation if the quantity is ≤ 6 (NetCol500-A120)

Figure 4-11 Top view of compact installation if the quantity is > 6 (NetCol500-A120)

If necessary, you can use a base to increase the height for compact installation, the dimensions of the raised base can be obtained based on the BOM code. Take the NetCol500-A120 as an example.

• When the quantity is 6 or less, if the wall height is 0 mm, the base height is 0 mm. If the wall height is 1000 mm or lower, the base height is 500 mm or higher.
• When the quantity is more than 6, if the wall height is 0 mm, the base height is 500 mm or higher. If the wall height is 1000 mm or lower, the base height is 1000 mm or higher.

Concrete Platform Requirements

The required concrete platform dimensions are different when the concrete platform is installed horizontally and vertically. The construction requirements are as follows:

• The concrete platforms are installed horizontally or with a slope of 5 degrees at most.
• Water can drain away after heavy rainfall.
• The strength of the concrete platform must be at least C20.

Concrete Platform Requirements for Horizontal Installation

For details about how to make concrete platforms to horizontally install an outdoor unit, see Figure 4-12.

Figure 4-12 Concrete platform dimensions

Figure 4-13 shows the mounting holes between the outdoor unit and the concrete floor. The mounting holes are long round holes and must be secured using eight M8x80 stainless expansion bolts.

Figure 4-13 Outdoor unit mounting holes

Concrete Platform Requirements for Vertical Installation

For details about how to make concrete platforms to vertically install an outdoor unit, see Figure 4-14. An outdoor unit must be secured to the ground or base using four M8x80 stainless expansion bolts and angle brackets.

Figure 4-14 Concrete platform dimensions

a: A base is required for securing. For details about securing during vertical installation, see Vertical Installation Scenario (NetCol500-A120).

Figure 4-15 and Figure 4-16 show the mounting hole for outdoor unit vertical installation.

(Optional) Space Dimensions for a Low Temperature Component

Low temperature components can only be installed horizontally. Before installing, prepare concrete platforms and drill holes by referring to the instructions in Figure 4-17.
