Installation instructions
bolts are completely tightened. Tighten the set screw per the appropriate value shown
in Table 46 according to the coupling size.
7.28 Piping connections
To avoid transmitting stress from piping connections between unit and plant, pipes must be laid
so as not to generate compressive stresses or tensile strains in the event of expansions or
contractions due to temperature changes. Steel pipes expand approx. 1 mm per metre per
100°C.
Johnson Controls Denmark recommends the pipe layout shown in example 2 of the sketch,
Fig. 85. Example 1 illustrates a pipe layout which is too rigid.

Refrigerant connection to compressor and unit
The connecting pipe must be welded onto a connecting branch on a stop valve. In order to pro-
tect the stop valve when welding, remove the insides of the valve. Do not put the insides back
into the valve until the weld has cooled off, see the instructions from the valve supplier.
The welding must be carried out according to the specifications and standards applying to the
plant in question.
