3.1.3 Requirements on Installation Space
The distance between the outdoor unit and wall or any other obstacle must be proper, as shown in
Figure 3-2.
(1) If a canopy is to be installed for the water heater outdoor unit, note that the heat dissipation and
absorption should not be affected.
(2) The outdoor unit must be installed in the host places a solid foundation, and ensure that the
outdoor unit is installed upright, and fastened with foundation bolts. If the vibration is strong, add rubber
gaskets to prevent vibration.
(3) Condensate drain of the outdoor unit: buckle snap the drainage joint of the outdoor unit into the

drainage pipe to the drainage mouth, and guide the drainage pipe to a proper place for drain.
3.1.4 Requirements on Foundation Installation
The concrete foundation of the outdoor unit must be strong enough. Ensure that the drainage is
smooth and that the ground drainage or floor drainage is not affected. The vertical installation mode
must be adopted and the outdoor unit must be fixed using foundation bolt. Requirements on the concrete
foundation are as follows:
(1) The concrete foundation must be flat and have enough rigidity and strength to undertake the
unit's weight during operation. The height of the foundation is 200 mm to 300 mm, which is determined
based on the size of the unit.
(2) The proportion of the cement, sand, and stone for the concrete is 1:2:4. Place 10 reinforced steel
bars (φ10 mm) with a space of 30 mm.
(3) Use the mortar to flatten the surface of the foundation.
(4) When the foundation is built on a concrete floor, crushed stones are not required. But the
foundation surface must be roughened.
(5) Clear the oil stains, crushed stones, dirt, and water in the reserved bolt hole of the foundation and
install a temporary cover before installing bolts.
