How to play
Swipe empty space with one finger to slide the view; use two fingers to turn and zoom. Double-tap empty space to reset the view. Use your finger like your hand: circle around a valve to turn it (anticlockwise opens, clockwise closes), drag hoses and wires onto their ports, press buttons, and hold the thermometer in place. Type every reading into the commissioning sheet yourself.
What do you need to wear?
Tap everything you need for pressure testing, brazing checks and handling refrigerant.
Pressure testing
On site, these are the figures you use for this unit.
| Strength test pressure | 48 bar 4.80 MPa |
| Hold strength test | 15 min, no drop |
| Tightness test (PS) | 44 bar 4.40 MPa · hold 30 min |
| Test gas | Oxygen-free nitrogen only |
| Service valves | Keep closed (unit is pre-charged) |
| Evacuation | Below 2 torr, 15 min hold |
Never go above the manufacturer's test pressure. Manuals often give it in MPa: 1 MPa = 10 bar.
