Hi
I'm having a problem with this water chiller EF Type WKL430S3.2
All the condenser air inlet filters and condenser coils are clean, the condenser fans are working and are controlled via a fan speed controller, but it seems the fans reach high speed to late or to slow and the unit sometimes trips on high discharge pressure(normal after i've left site, not when i'm there:confused:).

When the unit first starts the condensing temperature can easily reach 50deg C as the fans ramp up from low through to high speed, once the fans are at high speed the condensing temperature rapidly drops down to 30deg C. And then varying the condenser fans speed, maintain about 40 Deg C but on occasions the fans ramp up to late\slowly and the condensing temp exceeds it's safety and the unit cuts out.
Has any body got any factory settings\manuals so i can access\check the controllers settings as there are none on-site
Many thanks
