To install the drain connection:
1. Using teflon pipe thread tape, tape the threads on the cabinet drain connection.
2. Using an open end adjustable wrench, install the P-trap onto the connection. Make
sure the trap section is positioned down.
3. Push a piece of 3/8" ID tubing onto the trap and direct the tubing to a convenient
drain. Install a hose clamp on the tubing, if desired. A condensate evaporator (P/N
1900031) or condensate pump (P/N 184062) may also be used.
To connect the nylon adapter from the front drip trough, do not install a p-trap on the
nylon adapter (Figure 4-3). Push a piece of 3/8" ID tubing onto the nylon adapter and
direct the tubing to a convenient drain. Install a hose clamp on the tubing, if desired.
