It is the customer's responsibility to ensure that operators are trained in handling heavy goods and to enforce the relevant lifting regulations. The packaged SK VAP unit may be carried by fork lift from the underside, but caution should be exercised to ensure that the load is balanced before lifting. Refer to weights and measures section for system weight. - Page 6 At the heart of the SK VAP is the evaporative module, which is installed in an AHU or duct. Water is supplied to the top of a highly efficient bonded matrix, which is impregnated with silver for added hygiene. Dry air passes through this moist material picking up water vapour, raising the humidity as it does so.

2 - SK VAP Evaporative Module The SK VAP evaporative module is available in a range of widths (24” (600mm) - 118” (3000mm)) and heights (30” (750mm)) - 106” (2750mm)) to match the requirements of individual applications. The evaporative matrix consists of modular cassettes with low pressure drop which are available in a range of sizes and efficiencies. - Page 8 Evaporative Humidification / Cooling System When designing or installing an air handling system that incorporates an ‘SK VAP’, appropriate micro-organism and bacterial control methods MUST be considered and this should only be undertak en by suitably qualified persons. A risk assessment MUST also be undertaken in relation to control of micro-organisms and bacterial growth, especially Legionnaires disease.

- Page 12 Step 2 - Install Blanking Plates Once the SK VAP Evaporative Module has been positioned in the waterproof section of air handling unit, non corrosive blanking plates (not supplied) must be installed to prevent air bypass around the Module in the AHU.
- Page 13 1/2” BSP female threaded connection of the filling hose. The PureFlo Ag+ assembly should be positioned as close to the SK VAP Evaporative Module inlet as possible, via two 1/2” (15mm) compression fittings. It is advisable to mount the PureFlo Ag+ outside the AHU for ease of access.
- Page 14 Step 4 - Install Drain Pipework The SK VAP Evaporative Module features an integrated drain and overflow which must be connected to the main building drain with 3/4” (20mm) copper or stainless pipework. The drain assembly can be reversed to face in the opposite direction to suit either left or right feed pipe-work.
- Page 15 Evaporative Humidification / Cooling System Step 5 - Position the SK VAP Control panel The SK VAP Control panel should ideally be positioned as close to the Evaporative Module as possible for ease of servicing and maintenance. Use a 9-core electrical inter-connecting cable with a maximum length of 33ft (10m) for connection between the SK VAP Evaporative Module and the SK VAP Control Panel (see “Wiring Diagram”...
- Page 16 The electrical power cable to SK VAP Control panel should be suitably rated for a 120Vac / 10 Amp load in the US. The power supply should be connected to the G, L and N terminals as shown in “wiring diagram” on page 17.

Page 23: Pre-Commissioning Checklist
The use of mains water fed tanks and reservoirs is only permitted as part of a managed water treatment system. Check that the SK VAP Evaporative Module has a feed water supply in excess of 29 psi (2 bar) connected to the supplied filling hose. - Page 24 18. 4. Final Checks - Ensure that the system is operating correctly. Check for any leaks from the SK VAP evaporative module, and verify that the air supply is evenly distributed, and matches the design conditions for the system.

Page 25: Maintenance Schedule
In the event that the humidifier contains any residual water or has remained damp, and the temperature exceeded 68°F (20°C), the SK VAP should be cleaned and disinfected. Refer to the cleaning, disinfection and descaling instructions in this manual. -
Page 26: Maintenance Guide
“The control of Legionella bacteria in water systems”. Your water sampling / testing and disinfection regime must be based on details in the O&M manual and from results of a site specific risk assessment. For this type of Evaporative Humidifier, Neptronic recommend that disinfection is undertaken at least twice a year. Operations... -

Page 30: Cleaning And Disinfection
Before commencing cleaning and disinfection: Risk assess the situation. This should include but is not limited to observance of COSHH, L8 and the use of PPE, working from heights and ensuring a full understanding of the SK VAP System. Coordinate with relevant responsible persons. - Page 31 • Check for and complete maintenance requirements as per manufacturers instructions. • Always leave work area clean, dry and tidy. Step 8 - Recommission the system • Refer to the commissioning section of this manual. Neptronic ® www.neptronic.com...
