Section 6 Sealed System

6-7

4. Remove leads from compressor motor terminals.

5. Remove mounting nuts and washers.

6. After refrigerant is completely recovered, cut suction

and discharge lines as close to compressor as

possible. Leave only enough tubing to pinch off and

seal defective compressor. Plug or tape any open

system tubing to avoid entrance of moisture and air

into system. Remove inoperable compressor and

transfer mounting parts to new compressor.

7. Release holding charge (release slowly to avoid oil

discharge) on new compressor to ensure there is

no leak in seam or tubing. Reinstall rubber plug.

8. Install new compressor in exact same manner as

original compressor.

9. Reform both suction and discharge lines to align with

new compressor. If they are too short, use

additional lengths of tubing. Joints should overlap

0.5” to provide sufficient area for good solder joints.

Clean and mark area where tubing should be cut.

Cut tubing with tubing cutter. Work quickly to avoid

letting moisture and air into system.

10. Solder all connections according to soldering

procedure.

11. Install filter-drier between condenser outlet and the

capillary tube connection.

12. Evacuate and charge system using recommended

procedure described under Evacuating and

Recharging.

13. Reconnect compressor terminal leads in accordance

with unit wiring diagram and reassemble unit.

DO NOT OPERATE RECIPROCATING

COMPRESSORS WHEN CHARGING LIQUID

REFRIGERANT INTO SYSTEM THROUGH ITS

PROCESS TUBE.

NOTE

If low-side process tube is too short, silver solder four

inch piece of tubing onto process tube at this time.

On R-22 systems, compressor must NOT be left

open to atmosphere for more than 10 minutes to

prevent moisture contamination of oil.

Installing a New Compressor

Replacement of the compressor must be done in a

continuous sequence so the system is exposed to the

atmosphere no longer than necessary.

All replacement compressors are shipped with rubber

plugs in the suction and discharge tubes and contain the

correct oil charge and a holding charge of inert gas.

Before installing the replacement compressor, remove

the discharge plug and check for the pop sound of the

inert gas leaving the compressor.

If the compressor checks OK, reinstall the plug. Do not

remove any of the plugs again until the compressor is in

position and you are ready to braze the lines.

A new compressor which is cold (e.g. after having been

kept in a cold service van) should be left to warm to

the surrounding temperature before the plugs on the

compressor connections are removed. This will help

prevent condensation from forming in the oil and the

compressor. Also, avoid opening the system when any

of the components or lines are cold.

A process tube is connected onto the high-side process

tube where the line splits into capillary tubes. The other

process tube is connected to the tubing prior to entering

the accumulator.

Follow the numbered sequence for all products:

1. Disconnect electrical supply to unit.

2. Remove all components necessary to access the

compressor assembly in the unit.

3. Attach an approved self tapping line tap valve to the

process tube. Connect refrigerant recovery system

to tap valve. Turn on recovery system, open the

line tap valve, and allow refrigerant to flow into an

approved tank.

DO NOT use compressor if you do not hear this

sound.
