1.3 General warnings
Incorrect installation, adjustment, alteration, maintenance activity or repair may lead to material
or environmental damage and/or injuries. The appliance should therefore be installed, adapted or
converted by a skilled and qualified installer, taking into account national and international
regulations. A faulty installation, adjustment, alteration, maintenance activity or repair shall render
the warranty void.
1.4 Description of the Aqua Line panel [3]
A radiation panel is made up of multiples of four pipes attached to a profiled steel plate. Because
the pipes are actually located within the profile of the steel plate, there is a large contact area.
This also benefits the delivery capacity. The top of the radiation panel should be insulated on the
upper side using the loose insulating material supplied (to be fitted by you). This will restrict
undesirable upward radiation. The insulation strips must be cut to length manually.
1.5 Construction of the panel [3]
1 Reflector
2 Water-carrying pipe
3 Distributor
4 1” connections, water side
5 Mounting set (profile and carbine hooks)
6 Push-on connectors (optional)
7 Insulating material
8
De-aeration connection ½” (de-aeration nipple is not included in MHS’s scope of supply)
The panels are delivered in standard lengths of 4 or 6 metres. Longer lengths can also be created
by joining the panels together using the push-on connectors
[3]
. Note the water flow in this case.
In addition to the length, the width can also be adjusted. The distributors are also installed using
the push-on connectors. If required, the push-on connectors can be concealed using a reflector
concealing cover to create a neat finish

2.0 Selection and design advice [5]
In order to heat the room evenly, it is important to follow the steps below. These calculations
determine the type of panel, the panel length, distributors and the pressure drop. In connection
with the water side pressure drop and panel expansion, we advise you to keep the maximum
section length below 46 metres.

2.2 Steps to be followed
1. Determine the width, height and type of panel for the space.
[5]
T
wi
= 65ºC
T
wu
= 50ºC
T
omg
= 18ºC (Temp. in the room)
2. Determine the section length:
[5]
L
B
= L – 3m
L
B
= 45 – 3 = 42m
NOTE!
Only 4 or 6 metre panels may be used.
42m is divisible by 6. This results in 7 panels, each 6 metres in length
See table
[9]
3. Determine the installation height:
H
m
= H – 0.5m
H
m
= 5 – 0.5 = 4.5m
This is also the optimal distance from the centre point of each panel.
