Finishing The Job - Tadiran Telecom TGL-9 Installation Instructions

Do not open service valves or remove protective caps from tubing ends until all the connections are made.
Take care to avoid kinks or flattening of the tubing.
Bend tubing with special bending tools to avoid the formation of sharp bends.
Keep the tubing free of dirt, sand, moisture and other contaminants to avoid damaging the refrigerant system.
Avoid sags in the suction line to prevent the formation of oil traps.
Insulate the tubing with 3/8" - walled thermal pipe insulation. You can save time and improve insulation by inserting the tubing into
the insulation before making the connections. The suction and liquid lines should never come in direct contact.

Flaring and Connecting
Remove the protective cap from the flare fitting.
Remove the protective cap from the tubing and cut to the required length.
Make sure that the cut is perpendicular and clean, without burrs.
Slip the flare nut on the tubing and flare the tube end, using standard flaring tools.
Tighten the nut until resistance is met. Mark the nut and the fitting.
Using a suitable wrench, tighten an additional 1/4 turn.
Use the following specified torque, according to connection size:
The valves on the outdoor unit must remain closed until all four connections have
been made.
Air Vacuum and Refrigerant Charge
When all the fittings are connected, air must be expelled, as follows:
Open the service port cap on the suction line valve (large valve).
Connect the vacuum pump to the service port via the pressure gauge
and operate the pump for 15 minutes.
Make sure that full vacuum is present and disconnect the vacuum pump.
Open the liquid line valve (small valve) with an M-5 Allen wrench.
Open the suction line valve (large valve) with an M-5 Allen wrench.
The outdoor unit is supplied with sufficient refrigerant for eight meters (26 feet) of tubing. Add refrigerant and oil for each additional
meter of tubing used according to the table. If the tubing is shorter than 8 meters, release gas from the system through the service
valve into a recycling device.
Close the service port caps on the suction line.
Make sure that the valves are properly opened. Be careful not to open them more than required,
as this may damage the thread.
Replace the stem cap. Oil the cap beam and hands tighten the cap, until resistance is met.
Use a suitable wrench to tighten the cap by an additional 1/6 turn.
Check the system for refrigerant leakage using a leak detector.

Finishing the job

Hide the tubing where possible.
Make sure that the drainage tube slopes downwards along its
entire length.
Insulate tubing connections with the insulation supplied.
Fasten tubes to the outside wall.
Seal the hole through which the cables and tubing pass.
Connect the air conditioner to the power source and turn it on.
Check all air conditioner operating modes. Consult the User's
Manual.
