WARNING

Electrical shock hazard.

Have a properly trained individual perform these tasks.

Failure to do so could result in electric shock or death.

!

CAUTION

Cut hazard.

Wear gloves to avoid contact with sharp edges.

Failure to do so could result in personal injury.

SHIPPING DAMAGE

Upon receipt of equipment, the carton should be checked for external signs of shipping damage. If damage is found, the receiving party must contact the last carrier immediately, preferably in writing, requesting inspection by the carrier’s agent.

GENERAL

The equipment covered in this manual is to be installed by trained, experienced service and installation technicians.

The refrigerant system is completely assembled and charged. All internal wiring is complete.

The unit is designed for use with or without duct work.

Flanges are provided for attaching the supply and return ducts.

These instructions explain the recommended method to install the air cooled self-contained unit and the electrical wiring connections to the unit.

These instructions and any instructions packaged with any separate equipment required to make up the entire air conditioning system should be carefully read before beginning the installation. Note particularly “Starting

Procedure” and any tags and/or labels attached to the equipment.

While these instructions are intended as a general recommended guide, they do not supersede any national and/or local codes in any way. Authorities having jurisdiction should be consulted before the installation is made. See Page 3 for information on codes and standards.

Size of unit for a proposed installation should be based on heat loss calculation made according to methods of

Air Conditioning Contractors of America (ACCA). The air duct should be installed in accordance with the

Standards of the National Fire Protection Association for the Installation of Air Conditioning and Ventilating

Systems of Other Than Residence Type, NFPA No.

90A, and Residence Type Warm Air Heating and Air

Conditioning Systems, NFPA No. 90B. Where local regulations are at a variance with instructions, installer should adhere to local codes.

Manual 2100-647A

Page 4 of 30

DUCT WORK

All duct work, supply and return, must be properly sized for the design airflow requirement of the equipment. Air Conditioning Contractors of America

(ACCA) is an excellent guide to proper sizing. All duct work or portions thereof not in the conditioned space should be properly insulated in order to both conserve energy and prevent condensation or moisture damage.

Refer to Table 5 for maximum static pressure available for duct design.

Design the duct work according to methods given by the Air Conditioning Contractors of America (ACCA).

When duct runs through unheated spaces, it should be insulated with a minimum of one inch of insulation.

Use insulation with a vapor barrier on the outside of the insulation. Flexible joints should be used to connect the duct work to the equipment in order to keep the noise transmission to a minimum.

For the H Model Series 36-72, a 1/4" clearance to combustible material for the first 3' of duct attached to the outlet air frame is required. See Wall Mounting

Instructions and Figures 3A-D and Figure 4 for further details.

Ducts through the walls must be insulated and all joints taped or sealed to prevent air or moisture entering the wall cavity.

Some installations may not require any return air duct.

A metallic return air grille is required with installations not requiring a return air duct. The spacing between louvers on the grille shall not be larger than 5/8".

Any grille that meets with 5/8" louver criteria may be used. It is recommended that Bard Return Air

Grille Kit RG2W thru RG5W or RFG2W thru RFG5W be installed when no return duct is used. Contact distributor or factory for ordering information. If using a return air filter grille, filters must be of sufficient size to allow a maximum velocity of 400 fpm.

NOTE:

If no return air duct is used, applicable installation codes may limit this cabinet to installation only in a single story structure.

FILTERS

A 2" pleated MERV 8 is standard with each unit. The filter slides into position making it easy to service. This filter can be serviced from the outside by removing the filter access panel.

CONDENSATE DRAIN

A plastic drain hose extends from the drain pan at the top of the unit down to the unit base. There are openings in the unit base for the drain hose to pass through. In the event the drain hose is connected to a drain system of some type, it must be an open or vented type system to assure proper drainage.

Manual 2100-647A

Page 5 of 30

INSTALLATION

WALL MOUNTING INFORMATION

1. Two holes for the supply and return air openings must be cut through the wall as shown in Figures

3A-D on pages 9-12.

2. On wood frame walls, the wall construction must be strong and rigid enough to carry the weight of the unit without transmitting any unit vibration.

3. Concrete block walls must be thoroughly inspected to insure that they are capable of carrying the weight of the installed unit.

MOUNTING THE UNIT

1. These units are secured by wall mounting brackets which secure the unit to the outside wall surface at both sides. A bottom mounting bracket, attached to skid for shipping, is provided for ease of installation, but is not required.

2. The unit itself is suitable for 0 clearance, but the supply air duct flange and the first 3' of supply air duct require a minimum of 1/4" clearance to combustible material for Model Series H36, H42,

H48, H60 and H72. However, it is generally recommended that a 1" clearance is used for ease of installation and maintaining the required clearance to combustible material. See Figures

3A-D for details on opening sizes.

NOTE:

For side-by-side installation of two H**A models there must be 20" between units. This can be reduced to 15" by using a H**L model (left side compressor and controls) for the left unit and H**A (right side compressor and controls) for right unit.

3. Locate and mark lag bolt locations and bottom mounting bracket location (see Figures 3A-D).

4. Mount bottom mounting bracket.

5. Hook top rain flashing, attached to front-right corner of supply flange for shipping, under back bend of top.

6. Position unit in opening and secure with fasteners sufficient for the application such as 5/16 lag bolts; use 7/8" diameter flat washers on the lag bolts.

7. Secure rain flashing to wall and caulk across entire length of top (see Figures 3A-D).

8. For additional mounting rigidity, the return air and supply air frames or collars can be drilled and screwed or welded to the structural wall itself

(depending upon wall construction). Be sure to observe required clearance if combustible wall.

9. On side-by-side installations, maintain a minimum of 20" clearance on right side to allow access to control panel and heat strips, and to allow proper airflow to the outdoor coil. Additional clearance may be required to meet local or national codes.

10. Care should be taken to ensure that the recirculation and obstruction of condenser discharge air does not occur. Recirculation of condenser discharge air can be from either a single unit or multiple units. Any object such as shrubbery, a building or other large object can cause obstructions to the condenser discharge air. Recirculation or reduced airflow caused by obstructions will result in reduced capacity, possible unit pressure safety lockouts and reduced unit service life.

For units with blow through condensers, it is recommended there be a minimum distance of 10' between the front of the unit and any barrier or 20' between the fronts of two opposing (facing) units.

1. Use separate service equipment to avoid cross contamination of oil and refrigerants.

2. Use recovery equipment rated for R-410A refrigerant.

3. Use manifold gauges rated for R-410A (800 psi/250 psi low).

4. R-410A is a binary blend of HFC-32 and HFC-125.

5. R-410A is nearly azeotropic—similar to R-22 and

R-12. Although nearly azeotropic, charge with liquid refrigerant.

6. R-410A operates at 40-70% higher pressure than

R-22, and systems designed for R-22 cannot withstand this higher pressure.

7. R-410A has an ozone depletion potential of zero, but must be reclaimed due to its global warming potential.

8. R-410A compressors use Polyol Ester oil.

9. Polyol Ester oil is hygroscopic; it will rapidly absorb moisture and strongly hold this moisture in the oil.

10. A liquid line dryer must be used; even a deep vacuum will not separate moisture from the oil.

11. Limit atmospheric exposure to 15 minutes.

12. If compressor removal is necessary, always plug compressor immediately after removal. Purge with small amount of nitrogen when inserting plugs.

TOPPING OFF SYSTEM CHARGE

If a leak has occurred in the system, Bard

Manufacturing

recommends

reclaiming, evacuating

(see criteria above) and charging to the nameplate charge. If done correctly, topping off the system charge can be done without problems.

With R-410A, there are no significant changes in the refrigerant composition during multiple leaks and recharges. R-410A refrigerant is close to being an azeotropic blend (it behaves like a pure compound or single component refrigerant). The remaining refrigerant charge in the system may be used after leaks have occurred and then “top-off” the charge by utilizing the pressure charts on the inner control panel cover as a guideline.

REMEMBER:

When adding R-410A refrigerant, it must come out of the charging cylinder/tank as a liquid to avoid any fractionation, and to insure optimal system performance. Refer to instructions for the cylinder that is being utilized for proper method of liquid extraction.

!

WARNING

Failure to conform to these practices could lead to damage, injury or death.

SAFETY PRACTICES

1. Never mix R-410A with other refrigerants.

2. Alwasys use gloves and safety glasses. Polyol

Ester oils can be irritating to the skin, and liquid refrigerant will freeze the skin.

3. Never use air and R-410A to leak check; the mixture may become flammable.

4. Do not inhale R-410A; the vapor attacks the nervous system, creating dizziness, loss of coordination and slurred speech. Cardiac irregularities, unconsciousness and ultimate death can result from breathing this concentration.

5. Do not burn R-410A. This decomposition produces hazardous vapors. Evacuate the area if exposed.

6. Use only cylinders rated DOT4BA/4BW 400.

7. Never fill cylinders over 80% of total capacity.

8. Store cylinders in a cool area, out of direct sunlight.

9. Never heat cylinders above 125°F.

10. Never trap liquid R-410A in manifold sets, gauge lines or cylinders. R-410A expands significantly at warmer temperatures. Once a cylinder or line is full of liquid, any further rise in temperature will cause it to burst.

IMPORTANT INSTALLER NOTE

For improved start up performance wash the indoor coil with dishwashing detergent.

HIGH PRESSURE AND LOW PRESSURE

SWITCHES

All H**A/H**L wall mounted air conditioner series models are supplied with a remote reset for the high and low pressure switches. The first time the high or low pressure switches are tripped, they will reset automatically. If tripped a second time, reset the switches by turning the thermostat off, then back on again, resetting the compressor control module.

CONDENSER FAN OPERATION

NOTE: Certain models may be equipped with a low ambient control (LAC), and if so equipped the condenser fan motor may have a delayed start until system refrigerant operating pressure builds up.

After starting, the fan motor may or may not cycle depending upon ambient conditions. This is normal operation.

The condenser fan motor on 230/208 volt, one and three phase, 60 HZ units is a two-speed motor that comes factory wired on high speed for peak performance. If ambient conditions permit, it can be reconnected to low speed (red wire) for lower sound level. See unit wiring diagram.

SERVICE HINTS

1. Caution owner/operator to maintain clean air filters at all times and to not needlessly close off supply and return air registers. This reduces airflow through the system, which shortens equipment service life as well as increasing operating costs.

2. Check all power fuses or circuit breakers to be sure they are the correct rating.

3. Periodic cleaning of the outdoor coil to permit full and unrestricted airflow circulation is essential.

SEQUENCE OF OPERATION

COOLING – 24VAC from MV controller at terminal 4 (Y) pulls in compressor contactor, starting the compressor and outdoor motor. (See Note under Condenser Fan

Operation if equipped with low ambient control.)

Terminal 9 (G) indoor motor circuit is energized by the MV controller on any call for cooling operation or can be energized by manual fan switch on subbase for constant air circulation. On a call for heating from the

MV controller makes at the relay board pulling in heat contact for the strip heat and blower operation. On a call for second stage heat, R-W2 makes bringing on second heat contactor, if so equipped. See Table 1 on following page.

COMPRESSOR CONTROL MODULE

The compressor control module (CCM) is standard on all models covered by this manual. The compressor control module is an anti-short cycle/lockout timer with high and low pressure switch monitoring and alarm relay output.

Adjustable Delay-on-Make and Delay-on-Break Timer

On initial power up and any time power is interrupted to the unit, the delay-on-make period begins, which is the time set on the potentiometer (delay-on-break time) plus 10% of the delay-on-break setting. When the delay-on-make period is complete and the high pressure switch and low pressure switch are closed, the compressor contactor is energized. Upon shutdown

(end of the call for cooling), the delay-on-break timer starts and prevents restart (next call for cooling) until the delay-on-break period has expired.

During routine operation of the unit with no power interruptions, the compressor will operate on demand with no delay.

High Pressure Switch and Lockout Sequence

If the high pressure switch opens, the compressor contactor will de-energize immediately. The lockout timer will go into a

soft lockout

and stay in soft lockout until the high pressure switch closes and the delay-onbreak time has expired. If the high pressure switch opens again in this same operating cycle, the unit will go into

manual lockout

condition and the alarm relay circuit will energize. Recycling the wall thermostat or main power resets the manual lockout.

Low Pressure Switch, Bypass and Lockout Sequence

If the low pressure switch opens for more than 120 seconds, the compressor contactor will de-energize and go into a soft lockout. Regardless the state of the low pressure switch, the contactor will re-energize after the delay-on-make time delay has expired. If the low pressure switch remains open, or opens again for longer than 120 seconds, the unit will go into manual lockout condition and the alarm relay circuit will energize.

Recycling the wall thermostat or main power resets the manual lockout.

Alarm Relay Output

Alarm terminal is output connection for applications where alarm relay is employed. This terminal is powered whenever the compressor is locked out due to

HPC or LPC sequences as described.

NOTE:

Both high and low pressure switch controls are inherently automatic reset devices. The high pressure switch and low pressure switch cut out and cut in settings are fixed by specific air conditioner unit model. The lockout features, both soft and manual, are a function of the compressor control module.

Manual 2100-647A

Page 18 of 30

Adjustments

Adjustable Delay-on-Make and Delay-on-Break Timer

The potentiometer is used to select delay-on-break time from 30 seconds to 5 minutes. Delay-on-make (DOM) timing on power up and after power interruptions is equal to 2 minutes plus 10% of delay-on-break (DOB) setting:

0.5 minute (30 seconds) DOB = 123 second DOM

1.0 minute (60 seconds) DOB = 126 second DOM

2.0 minute (120 seconds) DOB = 132 second DOM

3.0 minute (180 seconds) DOB = 138 second DOM

4.0 minute (240 seconds) DOB = 144 second DOM

5.0 minute (300 seconds) DOB = 150 second DOM

During routine operation of the unit with no power interruptions, the compressor will operate on demand with no delay.

Typical Settings for Dual Unit Installation:

Unit 1: DOB set at 2 minutes and DOM is 132 seconds

Unit 2: DOB set at 4 minutes and DOM is 144 seconds

PRESSURE SERVICE PORTS

High and low pressure service ports are installed on all units so that the system operating pressures can be observed. A pressure table can be found on page

21 covering all models. It is imperative to match the correct pressure table to the unit by model number.
