1. Check SW01F. If it doesn't indicate to PIPE , Switch it to PIPE .
2. With the unit running in cooling mode, allow the system to settle. Observe surface temperature of suction pipe.
3. Should setting be necessary, switch off electrical supply, adjust the set point P1(Refer to Fig. 1, Table).
Switch on the electrical supply. Repeat this procedure until the suction temperature is between 0°C and +5°C.
4. Keep the unit operating on cooling mode at least 30 minutes.
If cycle isn't stable, switch off electrical supply, adjust switch P2 (Refer to fig. 2, graph).
Repeat this procedure unitl system is stable.
* Caution: SW01F should indicate PIPE to work properly. Ensure SW01F indicate PIPE .
