INSTALLATION
1 Locate and secure mount using bolting down holes (10) in base plate.
2 Ensure mounts are located in line with the unit base.
3 If applicable, remove compressor enclosure covers to allow access to mount fixing holes in
the unit base.
4 Lock the upper retaining nuts (6a) to the underside of the top plate (9) before a load is
applied.
5 Remove retaining nut and washer (2), lower the unit onto the mounts and replace retaining
nut and washer.
6 Beginning with the mount with the largest deflection, adjust the height of each mount using
the levelling screw (3).
CAUTION
Mountings must be adjusted incrementally in turn. Do not fully adjust 1 mount at a time as
this may overload and damage springs.
7 When all mounts are level, lock each into place using the levelling lock nut (4).

POSITIONING
The installation position should be selected with the following points in mind:
Position on a stable and even base, levelled to ensure that the compressor
operates correctly.
Levelling should be to +/- 5mm.
Where vibration transmission to the building structure is possible, fit spring anti-
vibration mounts and flexible water connections.
Observe airflow and maintenance clearances.
Pipework and electrical connections are readily accessible.
Where multiple units are installed, due care should be taken to avoid the
discharge air from each unit adversely affecting other units in the vicinity.
Within a side enclosed installation, the fan MUST be higher than the
enclosing structure.
Figures in brackets indicate airflow and maintenance clearances for side-enclosed
or multiple condensing unit applications.
Ensure there are no obstructions directly above the fans.
Allow free space above the fans to prevent air recirculation.
CAUTION
Prior to connecting services, ensure that the equipment is installed and
completely level.

PIPE SIZING GUIDE
Pipework sizes and routes should be set in accordance with good refrigeration practice.
PIPEWORK
INSTALLATION
The suction line should be insulated.
Liquid lines should be insulated in areas of high temperature or when exposed to
direct sunlight.
Special consideration should be given to vertical pipe runs and heat pump installation.
Unit performance will reduce if there are vertical rises of above 5m. Please consult
Airedale Service for risers above 10m.
When insulating refrigerant lines, cut approximately 30 - 50cm longer than the distance
between the units to ensure the insulation goes right upto the unit. Leave connections
uncovered for leak testing.
Remove burrs to the ends of the copper tube, holding the tube downward to avoid
allowing dirt to contaminate the tube.
Where applicable insert flare nuts removed from the pipework terminations and make a
flare at the end of the copper tube to conform with the following:
Inside surface is glossy and smooth
Tapered sides are of uniform length
Refrigeration lubrication is applied to mating surfaces
The installation of a sight glass close to the indoor unit is recommended.
Where applicable braze incoming pipe to rotalock service valve.

PRESSURE TESTING
In accordance with PED 97/23/EC, a strength test should be carried out in order to
ensure that all interconnecting joints, pipework and components are sufficiently strong to
cater for maximum permissible operating pressures. Once installation is completed, the
high side of the system should be strength tested with dry nitrogen to a recommended
minimum pressure of 27 barg and the low side to 17 barg.
CAUTION
Pressure testing can be dangerous if not properly conducted, personnel
undertaking pressure testing MUST be technically competent and suitably
qualified.
When installation is complete, the system should be pressure tested.
Fill the system with dry nitrogen to a pressure of between 17 bar/250psig and 34bar/
500 psig.
Record the pressure over a minimum of 60 minutes to detect major leaks (a 24 hour
period should preferably be allowed).
If a reduction in pressure is detected, trace the leak and repair before conducting a further
pressure test and charging.
EVACUATION
Evacuation for systems operating with R407C refrigerant to be carried out as follows (for
alternative refrigerants please refer to Airedale).
Use a high vacuum pump and connect to the high and low pressure sides of the system
via a gauge manifold fitted with compound gauges. A high vacuum gauge should be fitted
to the system at the furthest point from the vacuum pump.
Triple evacuation should be used to ensure that all contaminants are removed.
Operate the vacuum pump until a pressure of 1.5 torr (200 Pa) absolute pressure is
reached, then stop the vacuum pump to break the vacuum using oxygen free Nitrogen
until the pressure rises above zero.
The above operation should be repeated a second time.
The system should then be evacuated a third time but this time to 0.5 torr
absolute pressure.
Break with the correct refrigerant, until pressures equalise between the charging bottle
and the system.
ELECTRICAL
General
As standard the equipment is designed for 400V, 3 phase, 3 wire 50Hz and a
separate permanent 230V, 1 phase, 50Hz supply, to all relevant IEE regulations,
British standards and IEC requirements.
A fused and isolated electrical supply of the appropriate phase, frequency and
voltage should be installed.
The control voltage to the interlocks is 24V. Always size the low voltage interlock
and protection cabling for a maximum voltage drop of 2V.
CAUTION
Wires should be capable of carrying the maximum load current under non-fault
conditions at the stipulated voltage.
Avoid large voltage drops on cable runs, particularly low voltage wiring.
Once the connecting pipework is complete the electrical supply can be connected
by routing the cable through the appropriate casing hole and connecting the
cables, refer to the Wiring Diagram supplied with each unit.
CAUTION
A separately fused, locally isolated, permanent single phase and neutral supply
MUST BE FITTED for the compressor sump heater and control circuits, FAILURE to
do so could INVALIDATE WARRANTY.
