AIREDALE CR12 - Positioning; Mounting; Siting Recommendations; Pipework Connections

Installation Data
Positioning
• Unit must be positioned on an even base to ensure correct operation
• Observe airow and maintenance clearances
• Where multiple units are installed, due care should be taken to avoid the discharge air from each unit adversely
a󰀨ecting 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 xing 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 airow
would be obstructed

Holding Charge
The units are shipped with a holding charge of inert gas to guard against contamination or moisture during shipping and
storage.
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
Take care that the service connections are correctly made and in particular do not invert the inlet
and outlet connections.
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.
