Securing an Outdoor Unit

Context

When installing the outdoor unit, fully tighten the six stainless steel bolts for each support leg and the two stainless steel fastening bolts that secure each support leg to the ground.

Procedure

1. Remove the four angle brackets from the side panels of the outdoor unit by removing the two M6x16 stainless bolts from each angle bracket, as shown in Figure 4-40.
   Figure 4-40 Removing the bolts from the angle brackets
   

2. Install four legs on the four corners of the condenser by using twenty-four stainless M6x16 bolts (four stainless bolts for installing one leg), as shown in Figure 4-41.
   Figure 4-41 Installing legs
   

3. Put the four legs to the ground to lay the outdoor unit horizontally.

   When turning the outdoor unit, do not hold it by using two legs. Otherwise, the outdoor unit is damaged.

4. Use two M8x80 stainless steel expansion bolts to secure each of the four legs of the outdoor unit to the concrete platform or base.

Securing an Outdoor Unit to the Ground

1. Secure an outdoor unit to the ground through the four bracket angles by using M8x80 stainless steel expansion bolts on the side panels, as shown in Figure 4-42.

Securing an Outdoor Unit to the Base

The following takes the two-layer installation of outdoor units as an example. For the single-layer installation, perform only Step 1 and Step 3.

1. Secure the first layer of base to the ground using six M12x60 stainless steel expansion anchor bolts, as shown in Figure 4-43.
   Figure 4-43 Securing a base
   

   Only four bolts are required to secure the NetCol500-A060 double-layer base to the ground.

2. Secure the four columns.

   1. Secure the four columns to the first layer of base using twelve M10x30 stainless steel bolts, as shown by (1) in Figure 4-44.
   2. Secure the second layer of base to the middles of the four columns using twelve M10x30 stainless steel bolts, as shown by (2) in Figure 4-44.

3. Secure an outdoor unit onto the first layer of base.

   1. Lift the outdoor unit from the front onto the first layer of base, as shown by (1) in Figure 4-45.
   2. Secure the outdoor unit to the base using four angle brackets on the side panels. One M10x30 stainless steel bolt is used on the base side, and two M6x16 stainless steel bolts are used on the outdoor unit side, as shown in Figure 4-45.

4. Secure four slanting beams to the base using eight M10x30 stainless steel bolts, as shown in Figure 4-46.

5. Secure the three beams on the top to the base using six M10x30 stainless steel bolts, as shown in Figure 4-47.

   1. Lift the outdoor unit from the front onto the second layer of base, as shown by (1) in Figure 4-48.
   2. Secure the outdoor unit to the base using four bracket angles on the side panels. One M10x30 stainless steel bolt is used on the base side, and two M6x16 stainless steel bolts are used on the outdoor unit side, as shown in Figure 4-48.
   3. Secure the last beam on the top to the base using two M10x30 stainless steel bolts, as shown by (4) in Figure 4-48.

7. Connect the beam to the wall by routing M10x30 stainless steel bolts through the reserved tapped holes on the left and right sides at the top of the base.
