Installation Data
POSITIONING

Unit must be positioned on an even base to ensure correct operation

Observe airflow and maintenance clearances

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

When mounting the units adjacent to a wall or other vertical surface the condenser
should be positioned with the coil side facing the wall

Check all services are present and accessible
MOUNTING Fix the condenser down using the appropriate bolt holes in unit fixing legs.
SITING RECOMMENDATIONS
Horizontal Air Discharge 
Avoid where possible siting the unit where wind and air re-circulation may interfere
with the fan operation

A vertical air discharge unit is recommended for installation in windy locations or
wherever a horizontal airflow would be obstructed
PIPEWORK CONNECTIONS
CAUTION Take care that the service connections are correctly made and in particular do not
invert the inlet and outlet connections.

HOLDING CHARGE The units are shipped with a holding charge of inert gas to guard against contamination or
moisture during shipping and storage.
CAUTION The charge should be checked to indicate if leaks are present prior to evacuation.
If the charge appears to be either partially or totally lost, then the unit should be
carefully checked for signs of physical damage.
PIPEWORK INSTALLATION - GOOD PRACTICES
CAUTION The following information is based on a complete matched Airedale system
using R410A.
General Run the refrigeration lines taking care to ensure the following:

Use straight line routes where ever possible

Refrigerant lines should be insulated in areas of high/low temperature or when
exposed to direct sunlight

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

Avoid any contact between the discharge line and the liquid line
