Page 8: Areas Of Application
When operating in the vacuum range, there is a danger of air entering on the suction side. This can cause chemical reactions, a pressure rise in the condenser and an elevated compressed-gas temperature. Prevent the ingress of air at all costs! 8 | AQ451328892160en-000201 © Danfoss | Climate Solutions | 2023.07... - Page 9 (HP): 28 bar Design for other areas on request Fig. 6 HG7 „Motor version S“ in the evaporation range of = 5°C to 12,5°C limited condensing temperature up to t = 50°C.

A rule of thumb: Always lay the first pipe section starting from the shut-off valve downwards and parallel to the drive shaft. Rigid fixed point As short as possible Fig. 14 AQ451328892160en-000201 | 11 © Danfoss | Climate Solutions | 2023.07... -
Page 12: Operating The Shut-Off Valves
—> Service connection opened / shut-off valve opened. The connection which cannot be shut off is intended for safety devices. After activating the spindle, generally fit the spindle protection cap again and tighten with 14-16 Nm. This serves as a second sealing feature during operation. 12 | AQ451328892160en-000201 © Danfoss | Climate Solutions | 2023.07... -
Page 13: Suction Pipe Filter
For motor protection use a current-dependent and time-delayed overload protection device for moni- toring all three phases. Set the overload protection device so that it must be actuated within 2 hours, if there is 1.2 times the max. working current.

Switch on the compressor and allow to run for a minimum of 10 min. Check the oil level by: The oil must be visible in the sightglass. ATTENTION I f larger quantities of oil have to be topped up, there is a risk of oil hammer effects. If this is the case check the oil return! 24 | AQ451328892160en-000201 © Danfoss | Climate Solutions | 2023.07... -
