LOCATING THE UNIT

This series of packaged air conditioning units is designed for outdoor, rooftop or ground level installation.

The unit must be installed on a firm level foundation, of adequate strength to support its full operating weight. Some

form of vibration isolation such as rubber waffle pads should be installed between the unit and the supporting

structure.

1- The unit must not be located where it will be subjected to heavy downpour of roof drainage and must be above

ground level in areas that are prone to storm water flooding.

2- It must be high enough to permit good drainage of defrost water and allow any heavy ice to fall away form the

coil during defrost cycle.

Minimum recommend height is 250mm above ground level.

3- Keep exposed duct connections to a minimum to reduce duct losses.

4- When locating unit give consideration to, and locate unit as remote as possible from neighbours sleeping

areas to minimise noise, as heat pump loads are greatest at night time.

5- Where prevailing winter winds are known, if possible, position the outdoor coil away from the winds to reduce

defrost cycle time.

6- If possible, orient the unit outdoor coil towards the morning sun. This increases efficiency in heating and de-

creases the solar load on the unit in the summer cooling cycle.

7- The unit must be pitched slightly towards the indoor condensate drain outlet to provide positive drainage of

condensates.

8- All electrical and ductwork connections to the unit must be made via flexible connections to prevent transmis-

sion of vibration.

9- Service and air flow clearances must be allowed as indicated on the unit dimension sheet. If should be noted

that major service may require removal of the top panels. Particular attention should be paid to avoiding ob-

structions to the vertical condenser air discharge which may result in recirculation of the outdoor air.

10- In addition to the service clearances noted on the dimension sheet it is essential that provision is made for

adequate and safe service access.

11- The standard outdoor fans fitted to the units will not accept any resistance to air flow. Consequently, should it

be necessary to duct outdoor air to or from the unit, the ductwork system (including entering and leaving

weatherproof louvres if fitted) must be of negligible pressure loss.

Roof Top Units HA / 34 /45 /52 /61 / 75 / 89 / 110 RC Roof Top Unit

Any modifications carried out without the approval of Airwell may void the unit warranty.

Mains supply cables must be sized to ensure adequate voltage at the unit terminals when the unit is starting and

during full load operation.

Selection of supply cables must be determined by the following criteria:

1. Length of run supply cables.

2. Maximum starting current of unit  cables must supply adequate voltage at unit terminals for starting.

3. Method of installation of supply cables.

4. Capability of cables to carry unit full load current.

Starting and full load currents are provided on the units circuit diagram.

Short circuit protection must be provided at switchboard using HRC fuses or circuit breakers.

Where the choice of room controls includes either a remote room sensor and/or a set point unit these must be wired

in shielded cable and must not be run in the conduits with the power wiring (240/415 volt) as any induced voltage will

cause unreliable operation of the unit.

PLEASE NOTE

It is essential that the location selection for the thermostat sensor is representative of the space to be controlled and

where it will be readily affected by changes to the general space temperature.

Location adjacent to or in line with supply air outlets, or where its operation may be affected by direct sunlight,

outside doors or other external influences must be avoided.

The wire entry point must also be thoroughly sealed to prevent draughts influencing the operation of the sensor.

Failure to observe the above requirement may result in erratic and unreliable operation of the unit.

REFRIGERANT CHARGE

This heat pump is shipped pre-charged with the correct amount of R22 in the system. At unit start up, the operating

pressures and temperatures should be checked to verify the unit is properly charged by a qualified refrigeration

mechanic.

WWARNING

DEFROST CYCLE DRAINAGE

During the heating cycle ice forms on the surface of the outdoor coil. This ice is periodically removed during the units

defrost cycle and fairly large quantities of water (melted ice) will be dumped onto the area beneath the unit. Where

the unit is mounted on a roof this should not be a problem. However, where the free run off of this water is not

acceptable a drain tray of at least 75 mm deep and extending 75mm outside the units dimensions must be installed

beneath the unit and drain piping connected to it..

DUCTING REQUIREMENTS

All duct designs and heat loads must be calculated by a qualified air conditioning consultant or contractor in

accordance with normal good ducting practices.

Dimensions of duct connections are shown on the dimension sheet. Connection to the unit must be made via

flexible connections to prevent transmission of vibration and facilitate easy removal of panel work for major service

access. All ductwork must be insulated against noise and heat transmission.

FRESH AIR INTAKE

If required this must be fitted to the return air ducting as no special provision is made within the unit. All fresh air

intakes must be provided with air filters if they are connected to the ductwork between the return air filter and the

unit.

AIR FILTERS

Air filters are not provided and no provision is made for fitting them within the unit as standard. Air filters should

however be provided by the installing contractor and located in an accessible location between the return air grille

and the unit. These filters must be sized for a maximum face velocity of 2.0 m/sec.

ELECTRICAL INSTALLATION

The electrical installation must be carried out by a competent licensed electrician in accordance with local power

supply authority regulations and the appropriate unit wiring diagram.

4.3 Unit clean and free of excess installation material.

REGULAR MAINTENANCE

These units have been designed for minimum maintenance through the use of permanently lubricated components.

However, there are operational maintenance requirements that require regular attention to ensure optimum perfor-

mance.

Maintenance must be performed by appropriately experienced personnel.

WARNING: Isolate unit from power supply before working on unit.

1. REMOVAL OF PANELS

All access panels are removable by unscrewing the self tapping retaining screws.

2. FILTER CLEANING

The filters are provided and fitted by the installer and consequently specifications will vary with personal prefer-

ence. For normal air conditioning duty the common filter is either a 25 mm or 50 mm thick permanent type which

may be cleaned with the aid of a vacuum cleaner then washed in a weak solution of detergent and warm water.

However, the installers recommendation should be sought to ascertain the method and frequency of cleaning best

suited to the type used and the needs of the particular installation.

3. FAN DRIVE SYSTEM (Indoor)

Fan shaft and motor bearings are of permanently lubricated, sealed type and require no regular maintenance other

than a check on their general condition. The fan belt tension should be checked regularly and belt surfaces in-

spected for cracks or excessive wear. The belt should be tensioned to give a 20 mrn deflection under medium

pressure with the thumb on one of the straight runs.

4. OUTDOOR COIL

The coil surface will become laden with dust and maybe blocked by leaves or papers over a period of time. The

surface should be inspected periodically and cleaned down by hosing or steam cleaning as required.

5. ELECTRICAL

The contact surfaces of relays and contactors should be inspected regularly by an electrician and replaced as

judged necessary. On these occasions the control box should be blown out with compressed air to remove any

accumulation of dust or other contaminants.

6. REFRIGERATION

The refrigeration system is hermetically sealed and should require no regular maintenance. However, it is recom-

mended that the system be leak tested and the general operating and control systems be checked on a regular

basis. The operating pressures should be checked particularly at these times as they are an excellent guide to

other areas of the system in need of maintenance.
