2. INSTALLATION INSTRUCTIONS
2.1. Installing the unit
•
The HRglobal series is delivered with a base frame and in one piece (no assembly required).
The frame must not be removed, it is important for the rigidity of the unit. The base frame is designed to allow
manipulation of the unit.
•
Make sure the unit is installed on a flat surface.
•
Make sure to allow accessibility to all the cabinet’s components (controller, fans, heat exchanger, filters) to
allow easy maintenance, and possible replacement of defective elements. We recommend a minimum
clearance distance of 60 cm on the access side of the HRg 2000/3000/4000/5000/6000, and of 95 cm on the
access side of the HRg 1200 models. A clearance of 50 cm is recommended for all the 3 other sides.
•
Special care has been taken to deliver an airtight unit. Make sure the ductwork is also very airtight, especially
at the connections with the unit on the supply air side.
•
If the unit is installed outdoors, take the dominating winds into account when orientating the unit. Try to protect
the air inlet as much as possible from storm winds and rain.
2.2 Connecting the drain pan
•
To insure a good flow of the condensates the unit should be slightly inclined ( 2°) in the direction of the water
flow. This also avoids water stagnation in the drain pan.
•
The siphon must be properly installed to allow good water flow :
•
If the HRglobal unit is installed indoors:
Before starting, control the following points:
- if the drain pan is watertight;
- the connection between the drain pan and the evacuation pipe is airtight;
- the height of the siphon is at least of 120 mm;
- the pressure difference between outside and inside the unit cannot
exceed 350 Pa;
- check for the presence of a ventilation downstream of the siphon;
- the slope of the evacuation pipes is at least 1 cm/m;
- the siphon is accessible to allow cleaning
•
If the HRglobal is installed outdoors:
The siphon delivered with Global HR for outdoor application is a special
siphon with a membrane. It is thus not necessary to fit it to a drainage pipe as
the water can directly drop on the ground. The membrane integrated into this
type of siphon creates the air tightness.
•
In case of frost risk a wire heating coil should be installed (not delivered)
•
Once drainage system is in place make a water flow test, adjust inclination if necessary.
