3.2.4 Preparation for Installation
Installation
space
Prepare an installation space of this product where the operation, cleaning, maintenance, and
inspection work can be easily performed.
For performing overhaul of the compressor:
Because the crankshaft must be taken out from the main body during an overhaul work, a sufficient
space must be provided on the oil pump side, for a length corresponding to the full width of the
crankshaft, as measured from the crankcase end.
In addition, along the direction of taking out the cylinders, a clearance of at least 300 mm shall be
provided to avoid interference with other components such as pipes.
For the overhaul of the semi-hermitic motor, secure as enough space as at least 1.2 times of the
total motor length in the axial direction.
Lighting
Provide sufficient lighting to allow easy operation, cleaning, maintenance, and inspection work.
Ventilation
If natural ventilation is not sufficient, install proper ventilation fans according to the laws and
regulations.
Cooling
water
In this product, water cooling method has applied to cooling the compressor head cover and
ammonia semi-hermetic motor.
Closed type cooling tower facility should be employed to cool down the water used in this product.
Ensure that a sufficient amount of cooling water is provided as required by the customer's system.
3.2.5 Installation
For more information about the installation of this product, refer to the "Reciprocating Compressor
K-series Instruction Manual" Section 3.2.5.
3.2.5.1 Placement
Make sure that this product mounting surface of the package unit is sufficiently flat and level. If it is not
sufficiently leveled, tightly fastening this product mounting bolts can cause deformation of this product
and could hinder normal operation.
3.2.5.2 Piping
For the details of piping connection to the compressor, refer to the "Reciprocating Compressor K-series
Instruction Manual" Section 2.3.3.
For the precautions of refrigerant piping to the compressor, refer to the "Reciprocating Compressor
K-series Instruction Manual" Section 3.2.5.5.
