1. Install the condensing unit according to Application Guidelines C6.1.9 "Copeland EazyCool™ Large Outdoor
Condensing Units".
2. Prefill the unit with refrigerant and set all valves into the operating position.
3. Set up the unit controller (XMC25D) for the required application.
NOTE: The value of parameter D29 must be lower than the value C16-C17/2 (unit switching-off point) to avoid
the low-pressure alarm.
NOTE: The liquid line in OL(T)E units must be insulated to avoid air-moisture condensation and lack of
performance.
The XMC25D controller provides 2 programming levels:
▪
Pr1 with direct access
▪
Pr2 protected with a password: 321 (intended for experts)
