Place a wet rag against piping plate and around the

suction line connection. The wet rag must be in place

to guard against damage to the paint.

With the wet rag in place, position a field provided

elbow fitting to the air handler's suction line and line

set. Start nitrogen flow before brazing.

After the procedure is completed then remove the wet

rag.

Place wet rag against piping plate and around the

liquid line connection. Position liquid line elbow to air

handler's suction line and to line set. Start nitrogen

flow and begin brazing both connections and after

procedure is completed then remove both wet rags.

Refer to instructions provided with outdoor unit for leak

testing, evacuating and charging procedures.

Install access panel.

TRAPS MUST BE DEEP ENOUGH TO OFFSET MAXIMUM STATIC DIFFERENCES —

GENERALLY, TWO INCHES (51MM).

P-TRAP 49P66 REQUIRES A LARGER INSTALLATION SPACE THAN THE J-TRAP 91P90.

Main Drain

Connect the main drain and route downward to drain line

or sump. Do not connect drain to a closed waste system.

See Figure 7 for typical drain trap configuration.

Overflow Drain

It is recommended that the overflow drain is connected to

an overflow drain line for all units. If overflow drain is not

connected, it must be plugged with provided cap.

For downflow orientation, the overflow drain MUST be

connected and routed to a overflow drain line. See Figure

8 for main and overflow drain locations based on coil

orientation.
