3. INSTALLATION
3.5.6 LPHW coil
The LPHW coil is connected in the following way:
•
Connect the water supply to the inlet of the coil.
•
Connect the water return to the outlet of the coil, so the water flow is always counter
flow.
•
Connect the two-way valve outside the unit to the water system, as shown in the
drawings.
•
After mounting the water valve, set the maximum flow for the coil on the valve (see
also separate instructions).
•
Install the actuator to the valve and connect it to the electrical panel (se electrical
diagram)
NB!
When connecting the heat exchanger, counter hold with a suitable tool in order to avoid any
damage to the pipes.
3.5.7 Frost thermostat for LPHW coil
In case a frost thermostat is installed, it is easier to do so before installing the supply air
duct. You will find the thermostat delivered separately in a plastic bag together with all
brackets needed.
•
Mount the frost thermostat on the top deck of the unit with the bracket delivered with
the thermostat.
•
Mount the bracket for the bulb after the heating coil in the duct outlet.
•
Take the duct and drill a hole, run the bulb with the capillary tube through the hole and
fasten the bulb to the bulb holder. Then mount the duct on the DanX unit.
•
The thermostat is prewired and the wire only must be connected to the main terminal
strip of the unit (see wiring diagram).
