1.1 - R-410A - General info
• This air conditioner adopts the new HFC refrigerant
(R410A) which does not destroy ozone layer.
• R-410A refrigerant operates at 50%-70% higher
pressures than R-22. Be sure that servicing equipment
and replacement components are designed to operate
with R-410A.
• R-410A refrigerant cylinders have a dip tube which
allows liquid to ow out with the cylinder in a vertical
position with the valve at the top.
• R-410A systems should be charged with liquid
refrigerant. Use a commercial type metering device in
the manifold hose in order to vaporize the liquid
refrigerant before it enters in the unit.
• As for other HFC, R-410A refrigerant is only
compatible with oils recommended by the compressor
manufacturer.
• A vacuum pump is not enough to remove moisture
from oil.
• Oils absorb moisture rapidly. Do not expose oil to
atmosphere.
• Never open system to atmosphere while it is under
vacuum.
• When the system must be opened for service, break
vacuum with dry nitrogen.
• Do not vent R-410A into the atmosphere.
Use this unit only for factory approved applications.
The capacity and unit code are stated on the nameplate
data. CAUTION:

Before installation, check strength and horizontality of the
base so that abnormal sound does not generate.
According to the dimensions and clearances, x the base
rmly with the anchor bolts (Anchor bolt, nut: M10 x 2
pairs).
If the outdoor unit is installed in a very windy place,
protect the fan with a wind protection screen and check
that it works correctly.
5.1 - Opening cable knockouts (Fig. 4)
There is a pre-cut part that can be removed for running
wires.
Do not remove the unit front panel for easier drilling of
the knockouts. The pre-cut section of the sheet can be
removed by punching the 3 connection points along the
line rst using a chisel and nally with pliers (see g. 4).
When the cable knockout is open, remove the burrs and t
the cable protective bush supplied with the unit for cable
protection.
5.2 - How to remove the front panel (Fig. 5)
1. Remove screws of the front panel (See g 5).
2. Pull the front panel downward with the handle.
5.3 - Drain hose and base pan knockouts (Fig. 6)
See g. 6.
In case of draining through the drain hose, attach the drain
nipple (A) and use the drain hose (Inner diam.: 16mm)
sold in the market.When there is a possibility of freezing
of drain at the cold district or a snowfall area, be careful
for drainage ability of drain.
The drainage ability increases when knockout holes on the
base pan are opened. (Open the knockout hole to outside
using a soft-faced hammer (B), etc.).

6.2 - Water connections (Fig. 12)
Make the plate heat exchanger hydraulic connections
with the necessary components, using material which will
guarantee that the screwed joints are leak-proof. The
gures 11 shows a typical water circuit installation.
For an application with a water circuit, the following
recommendations must be taken into account:
1. The external circulation pump must be installed in the
return water pipe work immediately before the heat
pump (unit without hydraulic module).
2. It is advisable to install shut-off valves to allow
isolation of the most important circuit components, as
well as the heat exchanger itself.
These valves (ball, globe or buttery valves) should
produce a minimum pressure drop when they are
open.
3. Provide unit and system drains at the lowest system
point.
4. Install purges in the higher sections of the installation.
5. Pressure ports and pressure gauges should be installed
upstream and downstream of the external water
pump.
6. All piping must be adequately insulated and
supported.
Installation of the following components is obligatory:
1. The presence of particles in the water can lead to
obstructions in the heat exchanger.
It is therefore necessary to protect the heat exchanger
inlet with an extractable mesh lter. The lter mesh
gauge must be at least 10 mesh/cm2.
2. After assembling the system, or repairing the circuit,
the whole system must be thoroughly cleaned with
special attention paid to the state of the lters.

3. Pump ow rate control is made through a ow control
valve, which must be installed on the delivery pipe
during installation.
4. When water has to reach temperatures below 5°C, or
the equipment is installed in areas subject to
temperatures below 0°C, it is necessary to mix water
with inhibited ethylene glycol in suitable quantity.
Anti-seizing pump
The EREBA units are equipped with protection against
the seizing of the pump motor shaft. To allow this function,
do not empty the system or disconnect the power during
long periods of inactivity.
In any case, if the pump rotor shaft seizes after a long
period of inactivity, the user must do the following to
unblock it:
- Disconnect the power.
- Remove the front panel.
- Unscrew the shaft-protection plug on the back of the
pump.
- Insert a screwdriver in the slot and turn the rotor
shaft.
- Remount the protection plug.
- Reconnect the power.
System cleaning and water characteristics
In the case of a new installation, or cleaning the circuit, it
is necessary to perform a preventive cleaning of the
system.
In order to guarantee the good operation of the product,
each time you clean the system, replace the water or add
glycol, check that the liquid appears clear, without visible
impurities and that the hardness is less than 20 °f.
See g. 12.
Anti-freeze protection
If unit is switched off during the winter period when
outdoor air temperatures below 0°C can occur and
ethylene glycol is not used, it is recommended that the
entire system is drained through the drain unit valve, Fig 9,
item 3, and the system drain, Fig 11, item 5.

The EREBA units drive a 3-way valve to manage a
sanitary water storage tank.The operating logic provides
that, in case of a request for sanitary water by an
accumulation tank, the system controls a 3-way valve to
direct the hot water only to the tank and to operate at the
maximum capacity to provide water at 60 °C (compatible
with the operating envelope).
For operation, connect the 3-way valve between PINS 18,
N and 10 of the terminal strip (see Fig. 14). PINS 18 (Line)
and N (Neutral) power the valve (1ph ~ 230V, 2A max),
and a command signal (1ph ~ 230V, 2A max) is available
on PIN 10.
If using a valve with spring return, only connect PINS 10
and N.
The sanitary water request signal must be a Dry Contact
type (contact quality greater than 25mA @ 12V) that

To force the unit to operate at a lower maximum
frequency (to reduce noise) in the absence of a User
Comfort Interface, provide a Dry Contact (contact quality
greater than 25mA @ 12V) between PINS 13 and 14 of the
terminal strip (see Fig. 14). With the contact closed, the
unit will operate with a maximum frequency lower than
the standard one, otherwise it will operate in standard
mode.
For correct operation, it is necessary to congure the unit
using parameters 5 and 6 from the User Interface menu of
the CS1B.
The maximum noise reduction is about 3dB at 75% of the
maximum operating frequency of the compressor.
8.3 - Stop unit or defrosting signals
There are several signals available on the terminal strip to
indicate particular conditions or the stop of the external
unit.
The available signals are:
• Defrosting: When operating in Heating mode,
depending on the external environmental conditions,
the unit could perform defrosting cycles to clean the
external battery of any ice formations. Under these
conditions, it is not possible to guarantee the
requested temperature output water temperature,
which could reduce general comfort.
(PINS: 4-N, NUI CODE: 106 or 108)

8.8 - External alarm input
On PIN 21 of the terminal strip (see Fig. 14) an alarm
input (dry contact) is available to force of the unit.
When the contact is closed (Between pin 21 and 3) the
whole system is turned OFF (Unit OFF, WP OFF, GMC
alarm n° 2).When the dry contact open the system turns
ON and works in the last conguration.
It is possible to use this feature connected with different
external control systems and/or safety devices. For
example in case of danger an external safety device could
send an output alarm signal to close the contact. So the
outdoor unit turns off and remains in that condition until
the dry contact is reopened.

When OAT < Temperature set in NUI code 148 (default
value -20°C), if Par 108 is set to 1, on pin 11 of the terminal
strip a signal is available to activate a backup source for
SHW production.
8.7 - Signal for requesting an External Heat Source
(EHS)
Between PINS 4 and N of the terminal strip (see Fig. 14),
there is an output (1ph ~ 230V, 2A max) that can be
programmed using the remote User Comfort Interface
(see the control manual, Installation Menu code 106).
Two different strategies are possible based on Outdoor Air
Temperature:
1) Turn off heat pump and activate backup heat source.
This function is activated when OAT < Temperature
set in NUI code 148 (default value -20°C). In this
region heat pump turns off and external backup is
activated following one of below logic (NUI CODE
154):
• Output always on (NUI CODE 154=0) assumes
backup has its own regulation.
• ON/OFF based on room temperature set point
(NUI CODE 154=1)
• ON/OFF based on water temperature set point
(CODE 154=2) in case NUI is not installed/
available.
2) Both heat pump and backup heat source activated in
case Heat Pump delivered power is not enough.This
function is activated when OAT < Temperature set in
NUI code 150 (but OAT > temperature set in NUI
code 148). In this region HP keeps working and
backup heater turns on if set point on water is not
reached by 5°C (value can be set with NUI CODE
152) for 10 minutes (value can be set with NUI
CODE 151). Backup heater turns off when set point
on water is reached again.
