2-7-3 Determination of Water and Directions of the Unit
The water inlet and outlet pipe interfaces can be arranged in the right or left side of the unit. With
viewing from the unit air inlet (or along the air flow direction), if the water inlet and outlet ducts are at the
right side of the unit, the unit is called a Right-style Unit; conversely, it is a Left-style Unit. Pay attention
to distinguish between Right-style and Left style units when the pipe is connected.
2-7-4 Air Venting of the Coil
Each unit has a manual venting valve at the highest point of the coil. With the valve opened, the gas
stored in the coil can be released, keeping the unit in a stable flow of hot water and in a well-distributed
heat exchange condition. The air accumulated in the coil should be exhausted regularly.
2-7-5 Condensed Water Drainage
2-7-6 Air Duct Connection
The connecting between the return air duct and the external filter frame and that between the air outlet
flange and the air delivery duct must be flexible. The hard connection between the unit and the air outlet
flange must be prohibited. During the installation, the air duct should be provided with a support for its
exclusive use and its weight should not be carried by the unit, avoiding applying any extra load to the
unit.
2-7-7 Lifting Shock Absorbing
The hoisting equipment should be equipped with a shock absorber of good performance, preventing the
unit from the production of resonance and the increasing of low-frequency noise. It is suggested that
the shock absorber be installed at the side near the unit.
