Trane RT-SVX10C-EN specifications Coil Cleaners, Contains Refrigerant, No Step Surface

CAUTION

Coil Cleaners!

Coil cleaners can damage roofs, surrounding buildings, vehicles, etc. Cleaning substances should be checked to ensure that they will not cause damage to surround- ings. Coils and roof (if applicable) should berinsed thor- oughly. Do not spray coil cleaners in windy conditions.

Refrigerant Coils

To clean refrigerant coils, use a soft brush and a sprayer (either a garden pump-up type or a high-pressure sprayer).

Ahigh-quality detergent is also required; suggested

brands include “SPREX A.C.”, “OAKITE 161”, “OAKITE 166” and “COILOX”. If the detergent selected is strongly al- kaline (pH value exceeds 8.5), add an inhibitor.

1.Remove the access panels on both sides of the unit and the filters.

WARNING

No Step Surface!

Do not walk on the sheet metal drain pan. Walking on the drain pan could cause the supporting metal to collapse. Failure of the drain pan could result in death or serious injury.

Note: Bridging between the unit's main supports may consist of multiple 2 by 12 boards or sheet metal grating.

2.Straighten any bent coil fins with a fin comb. (Use the data in Table 5-7 to determine the appropriate fin comb size.)

3.Mix the detergent with water according to the manufacturer’s instructions. If desired, heat the solution to 150 F maximum to improve its cleansing capability.

WARNING

Contains Refrigerant!

System contains oil and refrigerant under high pres- sure. Recover refrigerant to relieve pressure before opening the system. See unit nameplate for refrigerant type. Do not use non-approved refrigerants, refrigerant substitutes, or refrigerant additives.

Failure to follow proper procedures or the use of non-ap- proved refrigerants, refrigerant substitutes, or refriger- ant additives could result in death or serious injury or equipment damage.

6.Rinse both sides of the coil with cool, clean water.

7.Inspect both sides of the coil; if it still appears to be dirty, repeat Steps 7 and 8.

8.Reinstall all of the components and panels removed in Step 2; then restore power to the unit.

Service & Maintenance (Continued)

Note: Refrigerant oil is detrimental to some roofing materials. Care must be taken to protect the roof from oil leaks or spills.

4.Pour the cleaning solution into the sprayer. If a high- pressure sprayer is used:

a.Do not allow the sprayer pressure to exceed 600 psi. The minimum spray nozzle angle is 15 degrees.

b.Spray the solution perpendicular (at 90 degrees) to the coil face.

c.Maintain a minimum clearance of 6" between the sprayer nozzle and the coil.

5.Spray the leaving-airflow side of the coil first; then spray the opposite side of the coil. Allow the cleaning solution to stand on the coil for five minutes.

6.Rinse both sides of the coil with cool, clean water.

7.Inspect both sides of the coil; if it still appears to be dirty, repeat Steps 7 and 8.

8.Reinstall all of the components and panels removed in Step 2; then restore power to the unit.

Steam or Hot Water Coils

To clean a steam or hot water coil, use a soft brush, a steam-cleaning machine, and water.

1.Verify that switches 1S1 and 1S70 are turned "OFF", and that the main unit disconnect is locked open.

2.Remove enough panels and components from the unit to gain sufficient access to the coil.

3.Straighten any bent coil fins with a fin comb. (Use the data in Table 5-5 to determine the appropriate fin comb size.)

4.Remove loose dirt and debris from both sides of the coil with a soft brush.

5.Use the steam-cleaning machine to clean the leaving-air side of the coil first; start at the top of the coil and work downward; then clean the entering-air side of the coil, starting at the top of the coil and working downward.

6.Check both sides of the coil; if it still appears dirty, repeat Step 5.

7.Reinstall all of the components and panels removed in Step 2; then restore power to the unit.
