REFRIGERANT PIPING

Any change in the diameter of the tubing must be made at the indoor connection. Line-set diameter is determined by the condenser service valve size.

Use of a larger diameter liquid or suc- tion line can harm the compressor!

Piston/Orifice Installation Instruction

Important: Replace the existing piston (before installing the unit) with the piston supplied in Kit Bag when any:

•WLHA24 evaporator is matched with a S1CA8000 or S1HA8000 condenser which has an 18,000 Btuh compressor (“8” in the capacity decoding field). The piston will need relacement only on the 18,000 Btuh zone.*

Your EMI evaporator unit contains the appropriate piston for your model. Refer to this document to determine if a change is required based on your condenser rating. If your

match is not listed below no piston change is required. (See chart below)
