Commissioning

Commissioning

General information

Before you start commissioning:

• Check that the filter casings are correctly seated.
• Remove protective film, if any.
• Ensure that all filter casings are clean and free from residues and foreign matter.
• Prime the ventilation and air conditioning system for 24 hours before you insert the filter element.

Volume flow rate balancing

To adjust the ventilation and air conditioning system you first have to carry out volume flow rate balancing for each ceiling mounted particulate filter. Volume flow rate balancing is required before initial commissioning.
Units with an optional volume flow limiter (TFCSCV): Once the volume flow rate has been set (by others), it will be maintained (mechanical self-powered).
Units with an optional damper blade: Adjust the damper blade to set the volume flow rate. You can adjust the damper blade before you install or after you remove the diffuser face and the filter element.

Inserting filters

• Do not unpack filter elements until you are ready to install them.
• Do not touch the filter; hold it by the edge only.
• Check filter elements for any damage; replace damaged filter elements.
• Insert only suitable Mini Pleat filter elements with a flat seal or fluid seal.
  

1. Remove the clamping mechanism (Fig. 6/3) from the HEPA filter housing.
   NOTICE!
   Do not damage the filter
   Handle filter elements with care and hold them only by the edges.

2. Set the filter element (Fig. 6/2) with the seal (Fig. 6/1) facing upwards into the clamping frame.

3. Insert the clamping mechanism with filter into the casing so that the four supports (Fig. 6/5) lock into the brackets (Fig. 6/7).

4.  Screw in the four clamping screws (Fig. 6/4) evenly with an Allen key size 4 to press the filter onto the filter holder (Fig. 6/8), max. torque 2 Nm.

5. Once you have inserted the filter element, check that there are no leaks, ⇒ ‘Leakage test on an installed filter’ on page 11.

6. Installing the diffuser face, ⇒ ‘Installing the diffuser face’ on page 10.

Installing the diffuser face

1. If the diffuser face has been supplied with a separate seal, glue the seal onto the back of the diffuser face.
2. Set the diffuser face (Fig. 7/3) onto the filter casing and fix it with the central fixing screw (Fig. 7/2). In the process, the central fixing screw can simply be inserted into the holding fixture (Fig. 7/4).
3. Put the decorative cap (Fig. 7/1) on the central fixing screw.

PCD diffuser face (PROCONDIF)
Turn the clamping screw M6 × 70 with the washer 6.4 × 20× 1.5 into the clamping frame (A) and tighten it; then fix the spacer (tube) with an M6 nut to the threaded part.

For diffuser face type PCD (PROCONDIF):
Insert the central honeycomb.

Maintenance

Maintenance applies mainly to the filter element.
Check the filter regularly and replace it, if necessary.
The service life of a filter depends mainly on how polluted the air is. Check the filter in intervals that are short enough so that you can anticipate any defects or problems before they actually occur.

Replace the filter immediately if any of the following is true:

• The reaching of the intended final differential pressure
• Hygiene problems (micro-organisms, fungal spores, odours, etc.)
• Filter defects (particle count has been exceeded)
• The maximum filter usage time has been reached (8 years, to VDI 3803, part 4).

**** You may replace a filter even before the defined final differential pressure has been reached if it is more economic.

Removing the diffuser face

Some maintenance jobs, such as sealing integrity testing, leakage testing, filter changes or cleaning, require you to remove the diffuser face.

1. Remove the decorative cap (Fig. 8/1) from the diffuser face (Fig. 8/3). For diffuser face type PCD (PROCONDIF): Remove the central honeycomb.
2. Remove the central fixing screw (Fig. 8/2) and then the diffuser face.

Leakage test on an installed filter

A leakage test is used as a functional test of the filter system to ensure that there are no leaks and that the filter element is without any defects (no small holes on the filter frame or on the seal, no leaks at the filter frame).

1. Measuring tube for raw air side measurement
2. Sealing cap
3. Aerosol feed

Leakage test due to particle measurement

1. Remove the diffuser face, Ä ‘Removing the diffuser face’ on page 11.

2. Open the measuring tube by removing the sealing cap.

3. Measure the particle concentration on the upstream side to ISO 14644-3 B6.

4. Measure the particle concentration on the downstream side to ISO 14644-3 B6.
   If there is a leak, seal it; then test for leakages again.

5. Close the measuring tube by putting the sealing cap into place.

6. Reinstall the diffuser face.

Leakage test by means of aerosol feed

1. Remove the diffuser face, ⇒ ‘Removing the diffuser face’ on page 11.

2. Open the aerosol feed by removing the sealing cap.

3. Feed the test aerosol.

4. Measure the particle concentration on the downstream side to ISO 14644-3 B6.
   If there is a leak, seal it; then test for leakages again.

5. Close the aerosol feed by putting the sealing cap into place.

6. Reinstall the diffuser face.

Sealing integrity test (option: FT or FTL)

Filter casings (option: FT or FTL) have a device for leakage testing. Sealing integrity is tested with a sealing integrity test device (see operating manual).

1. Connect the sealing integrity test device (Fig. 10/3) to the connection point on the filter (Fig. 10/2).
2. Apply at least 2000 Pa to the test groove (Fig. 10/1).
3. Check the leakage rate on the flow rate meter of the sealing integrity test device.
   ⇒ The value must not exceed 0.003% of the nominal volume flow rate.
   If this value is exceeded, adjust the clamping screws or the clamping frame; also check the seal, test groove and filter element for damage. Then repeat the sealing integrity test.

Differential pressure measurement

The initial differential pressure for TROX filters is given on the label on the filter frame.
There are two ways to measure the differential pressure:

Permanent measurement: Continuous differential pressure measurement and monitoring of the final differential pressure. This is done with a static differential pressure measuring device (Fig. 11/1), e.g.
TROX MD-UT, MD-APC or MD-DPC, using the pressure measurement points (Fig. 11/2) at the side or on the top of the casing.

Connecting a stationary measuring device
Plus (+) – to the ‘Plus’ measurement point (+)
Minus (–) – to the ‘Minus’ measurement point (–)

Temporary measurement: Temporary differential pressure measurement with a mobile measurement device connected to the internal measuring tube (Fig. 11/2). For this, you have to remove the diffuser face, ⇒ 11.

Connecting a mobile measuring device
Plus (+) – to the internal measuring tube (Fig. 11/2)
Minus (–) – Don’t connect; the differential pressure is measured against the room pressure.

Changing the filter

Personnel:

• Properly trained person
  Protective equipment:

• Industrial safety helmet

• Light respiratory protection

• Protective gloves
  

Before you start changing filters, switch off the ventilation and air conditioning system, or close the shut-off damper (if any) on TFC.

1. Remove the diffuser face, Ä ‘Removing the diffuser face’ on page 11.
2. Remove the clamping frame. To do so, loosen the four clamping screws (Fig. 12/1) (hexagon socket size 4). Lift the clamping mechanism (Fig. 12/2) out of the brackets (Fig. 12/3). Then remove it downwards.
3. Remove the dust-laden filter (Fig. 12/4) from the clamping frame, and put it into a plastic bag and dispose of it properly; see Ä ‘Disposal ’ on page 14.
4. If the filter casing is dirty, clean and disinfect it, Ä ‘Cleaning the filter casing’ on page 14.
5. Insert a new filter element, and reinstall the clamping frame and the diffuser face; see
   ⇒ ‘Inserting filters’ on page 9.

Disposal

ENVIRONMENT!
Risk of harm to the environment due to the incorrect handling of hazardous materials and substances.
Filters and cleaning materials that have been contaminated with bacterial, toxic or radioactive particles are considered hazardous waste and have to be disposed of by an authorised business in compliance with local regulations.

Disposing of filter elements with household waste is allowed only in the following cases:

• For unused filter elements
• For filter elements that have been exposed only to atmospheric outdoor air

Ordering replacement filters

To ensure permanent protection from particulate matter and other pollutants we recommend using only original TROX filters.

Original TROX filters carry a sticker on the frame with information on how to order replacements.

**** To avoid downtime of the ventilation and air conditioning system, we recommend you to always have the required filters in stock.

To order replacement filters: https://www.trox.de/onlineshop /filtergeraeteund-filterelemente-1df986693c21980d

Cleaning the filter casing

Personnel:

• Properly trained person

Protective equipment:

• Light respiratory protection

It is usually not possible to regularly clean and disinfect the ductwork between the second filter stage and the filter casing, and neither is it required for hygienic reasons. As a prerequisite, however, you have to keep the ducts clean during installation.
It is then sufficient to clean and disinfect (wipe) the filter casing and the diffuser face; this has to be done for the first time just before the ventilation and air conditioning system is switched on for the first time.
The casing may be cleaned with a damp cloth. Sticky dirt or contamination may be removed with a commercial, non-aggressive cleaning agent.
Cleaning agents that contain chlorine must not be used.

Once you have completed cleaning, disinfect the filter casing and any connecting rooms.
