The line set piping size is determined by the size of the indoor unit fittings.
Reducers are used at the outdoor unit to accommodate the correct gas line pipe size.
●
Install the unit horizontally.
●
The unit may be installed directly on a concrete verandah or a solid surface if drainage is good.
●
If the vibration may possibly be transmitted to the building, use a vibration-proof rubber isolator (field supply).
Precautions on Installation
●
Check the strength and level of the installation ground so that the unit will not cause any operating vibration or noise
after installation.
●
In accordance with the foundation drawing fix the unit securely by means of the foundation bolts. (Prepare four sets of
M12 foundation bolts, nuts and washers each which are available as field supply.)
●
It is best to screw in the foundation bolts until their length is 3/4” from the foundation surface.
