in compliance with ASHRAE15. (Factory-mounted.)
K. Hot Gas By-Pass: Permits continuous, stable operation at capacities below the mini-
mum step of unloading to as low as 5% capacity (depending on both the unit & operat-
ing conditions) by introducing an artificial load. Hot gas by-pass is available installed
on one or both refrigerant circuit(s).
L. Microprocessor Membrane Keypad Graphics on in lieu of Standard English:
1. French language.
2. German language.
3. Spanish language.
4. Italian language.
