10.13.1 Removing the high pressure switch (PSH1, PSH2)
1
Collect the refrigerant.
2
Disconnect the faston terminals -A-.
3
Remove high pressure switch -B- from the welding point -C- of
the discharge pipe -D- using a burner.
N O T E
•
If the refrigerant cycle is left for some time after removing
the high pressure switch, moisture and dirt may get into
the installation area of the high pressure switch. Therefore
replace the high pressure switch immediately after
removing. If this is not possible, seal the hole of the high
pressure switch.
•
Check that the aluminium sheet of the RC cover is not in
contact with the terminals of the high pressure switch.
•
Make sure to fix the sleeve of the faston terminals, as shown in the figure. If these terminals are exposed and
contact with the RC cover, it can cause electrical damage to the components.
10.13.2 Removing the high pressure sensor (Pd) and low pressure sensor (Ps)
1
Remove the connector for the pressure sensor wiring from the
PCB1.
N O T E
First remove the connector. If you do not, you may damage
the wiring.
2
Remove the refrigerant pipe from the high pressure sensor or
the low pressure sensor using two adjustable spanners -B- in
positions -A- and -C- by applying a tightening torque of 30 N.m.
N O T E
A: Spanner size: 14 mm
C: Spanner size: 17 mm
D: Do not use the adjustable spanners on this part.
E: Wire twisting should be within 3 winds.
