Step 1 - Position the SK VAP Evaporative Module

Installation should only take place after careful consideration of final position of the SK VAP Evaporative module and 

SK VAP Control panel and should be in accordance with AHU/duct-work installation diagram below.

Always discuss the position of the SK VAP module with your representative!

The following points must be considered

a -

The AHU / duct-work floor must be designed with a loading capacity capable of supporting the humidifier’s weight

when wet, as the largest unit will weigh 1016 lb (461kg) when in operation - see back of this manual for weights 

and measures. 

b -

Caution:   The SK VAP system must be installed within a waterproof AHU section. 

A drain pan with 

provision for running water to waste should be installed within the humidification section to allow 

for wetting that might occur during installation, commissioning,operation or servicing. Where drain 

pans are required to drain under gravity, ensure that the drains are trapped and primed and have 

enough head to overcome the pressure of the system and for hygiene reasons completely drain 

down. On commissioning the system, drainage of the humidification section should be tested.  The 

drain pan MUST drain fully and should be accessible for cleaning and disinfection as part of 

routine maintenance of  the system.

c -

The Module must be positioned on a minimum height 2” (50 mm) up-stand or runners to allow for drain 

pipe-work installation and removal of the tank and cassettes through the side of the AHU if required.

d -

Provisions should be made for the water inlet, drain pipe-work and interconnecting electrical cable to exit through

the side of the AHU

e -

Side access through a door (preferably such that the cassettes may be pulled through for maintenance) should

always be provided and a minimum of 24” (600mm) access front and rear of system for inspection, 

commissioning and maintenance.

f -

A perforated plate (60/40) should be installed upstream in cases where the air flow is uneven.

Very important: Use a level to make sure that the unit is level front to back and across the width when

installed. Failure to observe this point could result in flooding of the AHU / duct.
