lifting loads to prevent severe damage. Each
lifting appliance shall be capable of bearing the overall weight of the unit and maintaining suffi­cient weight allowance( →Page5,Fig. 1, Sche­matic diagram of unit lifting).
Use lifting steel pipe for unit lifting. When the delivery weight is within 2000kg, use steel pipe
with caliber and wall thickness ≥ Φ 48×6; when
the delivery weight is within 4000kg, use steel
pipe with caliber and wall thickness ≥ Φ 48×10.
Load must be carried by base, and the suspen­sion angle must not exceed 60°.
1.3.3 Storage of the unit
If the unit can not be installed after being deliv­ered into the site, following protections shall be applied:
Put the goods on the flat plate with base down-
wards, and the shell cannot be stressed directly.

2.3 Left/ right Hand pipe connection
( →Page 7, Fig. 3, Schematic diagram of distin­guishing left and right type)
For MAHU with Mono structure, Left or Right
Hand pipe connection is decided by judging the relative position of Air Inlet to the Water pipe position. (Air inlet is Left to the water pipe position, or Right to the water pipe position).
For MAHU with double deck or side by side
structure, Left or Right Hand pipe connection is decided by judging the relative position of Air Inlet to the water pipe position of the single Mono part which contain Coil Section. See below graph.
As default, the access door is on the same side as pipe connection.
