TIPS FOR SAVING ENERGY

Here are some tips that will help you minimize the power consumption when you use the air conditioner. You can use your air conditioner more efficiently by referring to the instructions below:

• Do not cool excessively indoors. This may be harmful for your health and may consume more electricity.

• Block sunlight with blinds or curtains while you are operating the air conditioner.

• Keep doors or windows closed tightly while you are operating the air conditioner.

• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.

• Speed up the fan to cool or warm indoor air quickly, in a short period of time.

• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air conditioner is used for many hours.

• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the air flow or weaken the cooling / dehumidifying functions.

Inspection

1 Check for damage after unit is unloaded.

Report promptly, to the carrier, any damage found to unit. Do not drop unit.

2 Check the unit nameplate to determine if

the unit voltage is correct for the application. Determine if adequate electrical power is available. Refer to the application specifications.

3 Check to be sure the refrigerant charge

has been retained during shipment. Access to 1/4" flare pressure taps may be gained by removing compressor compartment access panel.

Location and Recommendations

Unit Support

If unit is to be roof mounted check building codes for weight distribution requirements.

Location and Clearances

Installation of unit should conform to local building codes and the National Electrical Code. Select a location that will permit unobstructed airflow into the condenser coil and away from the fan discharge and permit unobstructed service access into the compressor compartment. Suggested airflow clearances and service clearances are given in Figure 1.

Placing and Rigging

Rig the unit using either belt or cable slings. The sling eyelet must be placed through the lifting holes in the base rail of the unit. The point where the slings meet the lifting eyelet should be at least 1.8m above the unit. Use spreader bars to prevent excessive pressure on the top of the unit during lifting.

NOTE

• The use of "spreader bars" is required when hoisting the unit (prevents damage to sides and top). Top crating can be used as spreader bars.

Roof Mounted Unit

On new roofs, the curb should be welded directly to the roof deck. For existing construction, nailers must be installed under the curb if welding is not possible. Be sure attach the down flow ductwork to the curb before setting unit in place.

When installing the unit, it must be level to insure proper condensate flow from the unit drain pan.

Slab Mount

"For ground level installation, the unit base should be adequately supported and hold the unit near level. The installation must meet the guidelines set forth in local codes."

INSTALLATION OF UNIT

Ductwork

Ductwork construction guidelines

Connections to the unit should be made with 76mm(3’) canvas connectors to minimize noise and vibration transmission.

Elbows with turning vanes or splitters are recommended to minimize air noise and resistance.

The first elbow in the ductwork leaving the unit should be no closer than three times blower diameter to avoid turbulence and back pressure.

Attaching Horizontal Ductwork to the Unit

All conditioned air ductwork should be insulated to minimize heating and cooling duct losses. Use minimum of 50mm(2’) of insulation with a vapor barrier. The outside ductwork must be weather proofed between the unit and the building.

When attaching ductwork to a horizontal unit, provide a flexible water tight connection to prevent noise transmission from the unit to the ducts. The flexible connection must be indoors and molded out of heavy canvas.

NOTE

• Do not draw the canvas taut between the solid ducts.

Change Airﬂow

1 Remove the covers from the down flow

2 Close the horizontal Supply and Return

openings on the front panel by attaching the covers firmly on to it which are removed from the down flow openings.
