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 air flow 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
