Packaged reversible air to water heat pumps
4PW61655-1 – 07.2010
Installation and operation manual

Charging water
For all versions
1 Connect the water supply to the drain and fill valve
2 Open the pressure regulating valve (only for EUWYP and
EUWYB) and shut-off valves
3 Use the air purge valves on the unit and purge valves installed in
the highest places in the circuit to remove all air when filling the
system
Only for EUWYP, EUWYB versions
Water must be filled until the system reaches the required
pressure (Pr). The pressure can be read on the manometer.
The value of the required water pressure (Pr) is depending on the
total water volume in the system and the pressure in the expansion
vessel (see previous chapter).
Refer to figure 7 – Required water pressure in function of water
volume and pre-pressure:
1 Calculate the total water volume in the entire system.
2 Check in figure 7 where the horizontal line of the set
prepressure (Pg) cuts the vertical line of the system water
volume.
3 At the cutting point, read the required water pressure (Pr) from
the lines in the figure.
Example 1
Total system water volume=130 l
Highest point of circuit above the EUWY=5 m
Pg=(5/10+0.3)=0.8 bar
Pr=±2.0 bar
Example 2
Total system water volume=190 l
Highest point of circuit above the EUWY unit=5 m
Pg=(5/10+0.3)=0.8 bar
Pr=±1.7 bar
PIPING INSULATION
The complete water circuit, inclusive all piping, must be insulated to
prevent condensation and reduction of the cooling capacity.
FIELD WIRING
Parts table
Refer to the wiring diagram supplied with the unit.
Following parts are to be connected during installation:
E5H........................Field heater (field supply, optional)
F1,F2,F3 ................Main fuses (field supply, obligatory)
H3P........................Indication lamp alarm (field supply, not
obligatory)
H4P,H5P.................Indication lamp compressor circuit 1, circuit 2
(field supply, not obligatory)
H6P........................Indication lamp general operation (field supply,
not obligatory)
L1,L2,L3.................Main terminals
N ............................Neutral
PE ..........................Main earth terminal
S7S ........................Switch for cool/heat selection or dual setpoint
selection (field supply, not obligatory)
S9S ........................Switch for remote start/stop selection or dual
setpoint selection (field supply, not obligatory)
X2M (E5H) .............Terminal for field heater connection (optional)
--- ...........................Field wiring
Power circuit and cable requirements
A power circuit must be provided for connection of the unit. This
circuit must be protected with the required safety devices, i.e. a slow
blow fuse on each phase and an earth leak detector. For maximum
cable section (mm
2
) refer to the table.
A Water volume (l)
B Installation height difference (m)
C Pre-pressure
D Factory setting (1.5 bar)
NOTE
In this example it is allowed to keep the pre-pressure
factory setting from 1.5 bar. In this case the initial
water-pressure must be ±2.2 bar
NOTE
In this example it is not allowed to keep the pre-
pressure factory setting from 1.5 bar.
NOTE
A terminal is foreseen in the switchbox on which a
heater (tape) can be connected for preventing the water
piping from freezing during the cold weather months.
Refer to the wiring diagram supplied with the unit.
All field wiring and components must be installed by a
licensed electrician and must comply with relevant Euro-
pean and national regulations.
The field wiring must be carried out in accordance with the
wiring diagram supplied with the unit and the instructions
given below.
Be sure to use a dedicated power circuit. Never use a
power supply shared by another appliance.
Description Legend 5~24 Hp
Powerlines L1, L2, L3, N 10
Main earth cable PE 10
NOTE
Select the power cable in accordance with relevant
local and national regulations.
Switch off the main isolator switch before making any
connections.
For units equipped with freeze protection:
Keep in mind that the heaters are automatically switched
off when the main isolator switch is switched off. For this
reason the main switch should be switched on during the
cold weather months.
