3.0 INSTALLATION

Install the unit in accordance with The American National Standard Z223.1-latest edition booklet entitled “National Fuel Gas Code”, and the requirements or codes of the local utility or other authority having jurisdiction. Unit should be installed in accordance with national and local safety

codes, including but not limit to ANSI/NFPS No. 70 or Canadian

Electrical Code Part 1, C22.1, local plumbing and wastewater codes and any other applicable codes. Additional helpful publications available from the “National Fire Protection Association” are: NFPA-90A - installation of Air Conditioning and Ventilating Systems 1985 or latest edition. NFPA-90B - Warm Air Heating and Air Conditioning Systems 1984.

3.1 PRE-INSTALLATION CHECK-POINTS

Before installation, carefully check the following:

1. For rooftop installation, be sure the structure has enough strength to support the weight of unit.

2. Clearances and provision for servicing.

3. Power supply and wiring.

4. Gas supply and piping.

5. Air duct connections and sizing.

6. Drain facilities and connections.

7. Location for minimum noise and vibration.

Typical outdoor installation in shown in Figure 3-2:

1. Select a location where external water drainage cannot collect around unit.

2. Locate unit where operating sounds will not disturb owner or neighbors.

3. The location of the unit should allow proper access for inspection and servicing.

4. Locate unit so roof runoff water does not pour directly on the unit. Provide gutter or other shielding at roof level. Do not locate unit in an area where excessive snow drifting may occur or accumulate.

5. Provide a concrete slab extending 3″ beyond all four sides of the

unit. The slab should be sufficiently high enough above grade to prevent surface water from entering the unit. The slab should be isolated from the foundation wall.

6. Pitch the slab approximately 1/2″ so that the unit will be pitched

toward the drain. See Figure 3-3.

7. It is essential that the unit be elevated above the base pad to allow

for defrost water runoff, condensate drainage, and possible

refreezing or condensate. Route condensation off the base pad to

an area that will not become slippery and result in personal injury.

Important: Do not interfere with opening in bottom of unit.

8. Where snowfall is anticipated, the height of the unit above the ground level must be considered. Mount unit high enough to be above average area snowfall to prevent snow from blocking the outdoor coil, to allow condensate runoff, and to allow combustion air to enter the combustion air inlet.

3.2 LOCATION CONSIDERATIONS

The metal parts of the unit may be subject to rust or deterioration in adverse environmental conditions. This oxidation could shorten the

equipment’s useful life. Salt spray, fog or mist in seacoast areas,

sulphur or chlorine from lawn watering systems, and various chemical contaminants from industries such as paper mills and petroleum refineries are especially corrosive.

If the unit is to be installed in an area where contaminants are likely to be a problem, give special attention to the equipment location and exposure:

1. Avoid having lawn sprinkler heads spray directly on the unit cabinet.

2. In coastal areas locate the unit on the side of the building away from the waterfront.

WARNING

Disconnect all power to the unit before starting maintenance. Failure to do so can cause electrical shock resulting in personal injury or death.

3. Shielding by a fence or shrubs may give some protection.

4. Elevate the unit off its slab or base enough to allow air circulation and avoid holding water against the base pan.

5. Frequent washing of the cabinet, fan blade and coil with fresh water will remove most of the salt or other contaminants that build up on the unit.

6. Regular cleaning and waxing of the cabinet with a good automobile polish will provide some protection.

7. Use a good liquid cleaner several times a year to remove matter

that will not wash off with water.

Several different types of protective coatings are offered in some areas. These coatings may provide some benefit, but the effectiveness of such coating materials cannot be verified by the equipment manufacturer. The best protection is frequent cleaning, maintenance and minimal exposure to contaminants.

3.8 DUCTWORK

Ductwork should be made and sized by installer and in accordance

with Air Manual from Conditioning Contractors of America and local codes.

NOTE

On ductwork exposed to outside air conditioning space, use at least 2” of insulation and a vapor barrier. Flexible joint may be used to reduce noise.

These units are adaptable to horizontal use as well as rear supply and

return air duct openings. To convert to downflow, use the steps is shown in 3.5.

A closed return duct system shall be used. This shall not preclude use

of economizers or ventilation air intake. Flexible joints may be used in the supply and return duct work to minimize the transmission of noise.

CAUTION

When fastening duct work to the side duct flanges on the unit, insert the screws through the duct flanges only. DO NOT insert the screws through the casing. Outdoor duct work must be insulation and waterproofed.

NOTE: The Commonwealth of Massachusetts requires the gas shut-off valve to be a T-handle gas cock.

2. Connect the gas line to the gas pipe inlet opening provided into the

1/2″ inlet valve. See Fig. 4-1 for typical piping.

3. Size the gas line to the furnace adequate enough to prevent undue pressure drop and never less than 1/2″ nominal pipe size.

4. Install a drip leg or sediment trap in the gas supply line as close to the unit as possible.

5. Install an outside ground joint union to connect the gas supply to the control assembly at the burner tray, Unions may not be installed inside the unit.

6. Gas valves have been factory installed. Install a manual gas valve where local codes specify a shut-off valve outside the unit casting.

7. Make sure piping is tight. A pipe compound resistant to the action of

liquefied petroleum gases must be used at all threaded pipe connections.

8. IMPORTANT: Any additions, changes or conversions required for the furnace to satisfactorily meet the application should be made by a qualified installer, service agency or the gas supplier, using factory-specified or approved parts. In the commonwealth of Massachusetts, installation must be performed by a licensed plumber or gas fitter for appropriate fuel.

IMPORTANT: Disconnect the furnace and its individual shutoff valve the gas supply piping during any pressure testing of that system at test pressures in excess of 1/2 psig or isolate the system from the gas supply piping system by closing its individual manual shutoff valve during any pressures equal to or less than 1/2 psig.

NOTE

Be sure to note supply and return openings. Refer to Fig. 3 and 4 for information concerning rear and bottom supply and return air duct openings.

3.9 RETURN AIR

WARNING

Never allow products of combustion to the flue products to enter the return air ductwork, or the circulating air supply. All return ductwork must be adequately sealed and secured to the furnace with sheet metal screws, and joints taped. All other duct joints must be secured with approved connections and sealed airtight. Failure to prevent products of combustion from being circulated into the living space can create potentially hazardous conditions, including carbon monoxide poisoning that could result in personal injury or death.

3.10 FILTERS

The installer must install field supplied filters in the return air duct. A field installed filter grille is recommended for easy and convenient access to the filters for periodic inspection and cleaning. Filters must have adequate face area for the rated air quantity of the unit. See air

delivery tables for recommended filter size.

4.3 ADJUSTING OR CHECKING FURNACE INPUT

- Natural Gas Inlet Pressure 5″ -10.5″ W.C.

- LP Gas Inlet Pressure 11″ -13″ W.C.

- Natural Gas Outlet Pressure 3.5″ W.C.

- LP Gas Outlet Pressure 10″ W.C.

Supply and manifold pressure taps are located on the gas valve body

1/8″ N.P.T.

Use a properly calibrated manometer gauge for accurate gas pressure readings. Only small variations in the gas flow should be made by means of the pressure regulator adjustment. Furnaces functioning on LP gas must be set by means of the tank or branch supply regulators. The furnace

outlet pressure should be set at 10″ W.C. at the gas control valve.

To adjust the pressure regulator, remove the regulator cap and turn the adjustment screw clockwise to increase pressure or counterclockwise to decrease pressure. Then replace the regulator cap securely. Any necessary major changes in the gas flow rate should be made by

changing the size of the burner orifices. To change orifice spuds, shut

off the manual main gas valve and remove the gas manifold. For elevations up to 2000 feet, rating plate input rating apply. For high

altitudes (elevations over 2000 feet), see conversion kit index for derating and orifice spud sizes.

Check of input is important to prevent over-firing of the furnace beyond its designated input, NEVER SET INPUT ABOVE THAT SHOWN ON THE RATING PLATE. Use the following formula to determine input rate.

C.F.H. Required=

Start the furnace and measure the time required to burn on cubic foot of gas. Prior to checking the furnace input, make certain that all other gas appliances are shut off, with the exception of pilot burners. Time the meter with only the furnace in operation. IMPORTANT NOTE FOR ALL ALTITUDES ABOVE 2000 FEET: The

main burner orifices in your furnace and in these kits are sized for the

nameplate input and intended for installations at elevations up to 2000 feet in the USA or Canada, or for elevations of 2000-4500 feet in Canada if the unit has been derated at the factory. For elevations above 2000 feet IN THE USA ONLY (see ANSI-Z223.1), the burner

orifices must be sized to reduce the input 4% for each 1000 feet

above sea level. NOTICE: Derating of the heating input for high altitude in the field is

unlawful in Canada (refer to CAN/CGA 2.17). Units installed in

altitudes greater than 2000 feet must be shipped from the factory or

from a factory authorized conversion station with the heating input

derated by 10% so as to operate properly in altitudes from 2000-4500 feet.

WARNING

installation & owner’s manual

The manufacturer recommends that a qualified installer, service agency or the gas suppler visually inspect the burner flames for the desired flame appearance at the beginning of the heating season and approximately midway in heating season. The manufacturer also recommends that a qualified installer, service agency or the gas supplier clean the flame sensor with steel wool at the beginning of the heating season.

WARNING

Disconnect main electrical power to the unit before attempting maintenance. Failure to do so may result in electrical shock or severe personal injury or death.

7.3 LUBRICATION

IMPORTANT: DO NOT attempt to lubricate the bearings on the blower motor or the induced draft blower motor. Addition of lubricants can reduce the motor life and void the warranty.

The blower motor and induced draft blower motor are prelubricated by the manufacturer and do not require further attention.

A qualified installer, service agency or the gas supplier must periodically clean the motors to prevent the possibility of overheating due to an accumulation of dust and dirt on the windings or on the motor exterior. And, as suggested elsewhere in these instruct ions, the air filters should be kept clean because dirty filters can restrict air flow and the motor depends upon sufficient air flowing across and through it to prevent overheating.

7.4 COOLING SECTION MAINTENANCE

It is recommended that at the beginning of each cooling season a qualified installer or service agency inspect and clean the cooling section of this unit. The following areas should be addressed: evaporator coil, condenser coil, condenser fan motor and venturi area.

To inspect the evaporator coil:

1. Remove the filter access panel and the blower/evaporator coil access panel.

WARNING

2. Unplug the wires from the circulating air blower and the limit control. Remove the two screws and slide the blower out of the unit sideways.

3. Shine a flashlight on the evaporator coil (both sides) and inspect for

accumulation of lint, insulation, etc.

4. If coil requires cleaning, follow the steps shown below.

Cleaning Evaporator Coil, Drain Pan, Condensate Drain, Condenser Fan, Circulation Air Blower and Venturi

1. Remove the screws from the filter access panel and the blower/evaporator coil access panel from the unit. Remove the filter access panel and the blower/evaporator coil access panel.

2. The coil should be cleaned when it is dry. If the coil is coated with dirt or lint, vacuum it with a soft brush attachment. Be careful not to bend the Coil fins.

3. If the coil is coated with oil or grease, clean it with a mild detergent-and-water solution. Rinse the coil thoroughly with water. IMPORTANT: Do not use excessive water pressure. Excessive water pressure can bend the tins and tubing of the coil and lead to inadequate unit performance. Be careful not to splash water excessively into unit.

4. Inspect the drain pan and condensate drain at the same time the evaporator coil is checked. Clean the drain pan by flushing with water and removing any matters of obstructions which may be present.

5. Flush the drain tube with water. If the drain tube is blocked, it can usually be cleared with high pressure water.

6. The venturi should also be inspected for items of obstruction such as collections of grass, dirt or spider webs. Remove any that are present.

7. Inspect the circulating air blower wheel and motor for accumulation

of lint, dirt or other obstruction and clean if necessary. Inspect the blower motor mounts and the blower housing for loose mounts or other damage. Repair or replace it necessary.

Re-assembly

1. Place the condenser coil protective grille back on unit and replace all screws.

2. Place top panel back on unit and replace all screws.

3. Set condenser fan grille assembly on top of the unit with the fan on top and the motor wires on the venturi side. Run the fan motor wires through the bulkhead and pull wires through the hole on the bottom of the control box on the left side and into the control box. Reconnect fan motor wires per the wiring diagram attached to the back of the control box cover.

4. Replace wire strain relief in bulkhead after the slack is pulled out of the wires on the fan side. This will assure wires will not be damaged by the fan during unit operation.

6. Replace the circulating air blower, making sure that all wires are properly reconnected per the unit wiring diagram.

7. Replace the filter and blower/evaporator coil access panels.

8. Replace the control box cover and controls access panel.

9. Restore electrical power to the unit and check for proper operation, especially the condenser fan motor.

7.5 REPLACEMENT PARTS

Contact your local distributor for a complete parts list.

Cleaning Condenser Coil

1. Remove screws from condenser fan grille assembly and lay grille over on the unit top panel.

2. Remove the controls access panel and the control box cover.

3. Disconnect the outdoor fan motor wiring from the compressor contactor and capacitor. Remove the strain relief in the bulkhead and pull the fan motor wires through. Set grille assembly to the side.

4. Remove the screws that secure the unit top to the unit. Remove the top and set the unit top to the side.

5. The coil should be cleaned when it is dry. If the coil is coated with dirt or lint, vacuum it with a soft brush attachment. Be careful not to bend the coil fins.

6. If the coil is coated with oil or grease, clean it with a mild detergent-and-water solution. Rinse the coil thoroughly with water. IMPORTANT: Do not use excessive water pressure. Excessive water pressure can bend the fins and tubing of the coil and lead to inadequate unit performance. Be careful not to splash water excessively into unit.

7. Go to next section for cleaning the evaporator coil.

8.0 OPERATION

Most single phase units are equipped with Permanent Split Capacitor

(PSC) motors (no start relay or start capacitor). It is important that

such systems be off for a minimum of 5 minutes before restarting to

allow equalization of pressures. Do not move the thermostat to cycle

unit without waiting five minutes. To do so may cause the compressor to stop on an automatic open overload device or blow a fuse. Poor electrical service can cause nuisance tripping in overloads or blow fuses. IMPORTANT: The compressor has an internal overload protector. Under some conditions, it can take up to 2 hours for this overload to reset. Make sure overload has had time to reset before condemning the compressor. The control allows the blower to operate for up to 90 seconds after the thermostat is satisfied.

8.1 CONTROL SYSTEM OPERATION

1. Heating mode The wall thermostat “calls for heat,” closing the R--to--W circuit. The

furnace control performs a “NORMAL FURNACE OPERATING SEQUENCE”.

2.Cooling mode In the cooling mode, The thermostat closes the R--to--G--and-- Y

circuits. The thermostat will energize the compressor contactor and the indoor blower relay. the blower motor will operate on

BLOWER-SINGLE/HI speed,After the thermostat is satisfied, the

compressor is de-energized and the cool mode delay-to-fan-off period begins. After the delay-to-fan- off period ends, the circulator fan is de-energized. The indoor blower can be operated continuously by setting the thermostat fan switch at the “ON” position.

3. Fan mode When the circuit R--to--G is closed by the thermostat, the blower motor will operate on BLOWER-LOW speed , If the thermostat fan switch is moved to the ON position, the circulator fan will be energized. When the fan switch is returned to the AUTO position, the circulator fan will be de-energized.

8.2 FAN DELAY ADJUSTMENT

As shipped, the circulator blower fan will remain on for 90 seconds after the gas valve closes. When a call for cooling occurs，the circulator fan comes on and remains on for 80 seconds after the call for cooling ends. During normal heating operation, the circulator fan will come on approximately 45 seconds after the gas valve opens.

● The air distribution system has the greatest effect on airflow. The duct system is totally controlled by the contractor. For this reason, the contractor should use only industry-recognized procedures.

● Each ton of cooling requires between 350 and 450 cubic feet of air per minute (CFM), or 400 CFM nominally.

● Duct design and construction should be carefully done. System performance can be lowered dramatically through bad planning

or workmanship.

● Air supply diffusers must be selected and located carefully. They must be sized and positoined to deliver treated air along the

perimerter of the space. If they are too small for their intended airflow, they become noisy. If they are not located properly, they

cause drafts. Return air grilles must be properly sized to carry air back to the blower. If they are too small, they also cause

noise.

● The installers should balance the air distribution system to ensure proper quiet airflow to all rooms in the home. This ensures a

comfortable living space.

● An air velocity meter or airflow hood can give a reading of system CFM.

● When installation, installer should select the air speed according to the actual setting static pressure. Please refer to the Table

10-1 & Table 10-2.
