Mounting in the

 vertical

 orientation shown above IS NOT ADVISABLE 

for LPHW units due to the actuator being below the valve. 

Service/Maintenance Access – Unit must be installed with a 

minimum of unit depth as additional clearance i.e DS1A-NES 

either allow 233mm above or below unit.

For systems which include supply fans with heating other than 

where the BMS (0-10V) has control, the appropriate user control is

 

required (i.e. ES-LCD or ES-CI

)

2.0 Handling

Always handle the units carefully to avoid damage and distortion.
Care must be taken to ensure any slings used for hoisting do not
damage the casing or the control module components. 

Note: The weight of the unit is on the rating plate.

Figure 1: Typical lifting methods.

3.0 Installation

Installation must be carried out by competent personnel, in 
accordance with good industry practice, the appropriate authority

 

and in conformance with all statutory and governing regulations. 

Access to the unit for maintenance is via the top or bottom lid,

 

therefore this should be taken into account before installation 
takes place (See important note below).

he vertical

 orientation

 below

 is not advisable

for quick and easy installation, either surface mounted or suspended
with drop rods.
