5. Run the system for a few minutes to allow it to stabilize. Where possible, charge to a sweat line on the
evaporator. Typical suction pressure on short lines at UK conditions should be approx. 3.8bar (55
psig).
6. Transfer the motor wire back from terminal 1 to 4 on the HPC pcb.
7. Head pressure controller
The HPC is factory set to suit R407C refrigerant. It may be necessary to adjust this to suit site
conditions, to raise or lower the nominal head pressure.
I. With the system switched off, connect a high pressure gauge to the liquid line service valve.
II. Switch on the system, indoor fan set to high speed and run for a few minutes to stabilise.
III. The head pressure should be approximately 275-280
psig (18.9-19.6 barg). To achieve this adjust the
screw clockwise to increase the pressure by approx
5 psig (0.5barg)
NOTE: Min fan speed (0 rpm) and fan cut in pressure (230psig /
15.6 barg) are factory set and not adjustable.
MOUNTING
Whether floor or wall mounted, it is essential that the
mounting surface is capable of supporting the unit weight.
Leave space around the unit for air circulation and access
for installation and maintenance.
