Copeland ZX*Y refrigeration units
Quick installation guide
1. Install the refrigeration unit according to Application Guidelines AGL_Unit_ZX_A2L_A1_EN "Copeland outdoor
refrigeration units – ZX*Y range".
2. Prefill the unit with refrigerant and set all valves into operating position.
3. Set up the unit controller (XCM25D) for the required application.
NOTE: If a room thermostat is used to control the solenoid valve, only parameters C01 and C02 (cut-
in/cut-out pressures) must be adjusted to perform a pumpdown. The value of parameter D29 must be
lower than C02 to avoid a low-pressure alarm.
The XCM25D controller provides 2 programming levels:
▪ Pr1 with direct access
▪ Pr2 protected with a password (intended for experts)
