5. Make sure reversing valve (if included) is energized

but neither fan nor compressor is running.

6. Reduce temperature setting to about five (5) deg-

rees  below  room  temperature.  Fan  should  start

immediately and compressor shall start after about

three  (3)  minutes.  In  a  unit  with  two  (2)  circuits

second  compressor  shall  start  about  three  (3)

minutes after first one has started.

7. Verify unit is cooling.

8. Turn system mode to HEAT and then set tempera-

ture  to  about  five  (5)  degrees  above  room  temp-

erature. Compressor shall stop and then start after

about  three  (3)  minutes.  In  a  unit  with  two  (2)

circuits second compressor  shall start about three

(3) minutes after the first one has started.

9. Verify unit is heating.

10. Set  the  thermostat  to  the  desired  and  tempera-

ture.

11. Instruct customer on the unit, the thermostat ope-

ration and the required maintenance.

12.

Record all pressures, flow rates and temperatures

related to operation.

Optional Equipment / Accessory

Any optional equipment and/or accessory which may come

with  the  unit  must  be  checked  according  to  its  specificat-

ions.

Commissioning

The commissioning of an air-conditioning system is the pro-

cess  of  achieving,  verifying  and  documenting  the  perform-

ance  of  that  system  to  meet  the  operational  needs  of  the

building.  This may  not  be  the  formal  process  in  smaller

structures,  such  as  a  normal  residence,  but  some  form  of

owner acceptance will occur. Adjustments made during the

commissioning phase may include air or water balancing or

configuration of controls and operational sequences.

Air Balancing

The  correct  air  balancing  is  imperative  to  achieve  optimal

comfort  and  efficiency  of  the  entire  system.  Unqualified

personnel should not attempt to adjust air circulation, as all

system has unique operating characteristics. Professional air

balance specialists should be employed to establish actual

operating conditions, and to configure the air delivery sys-

tem for optimal performance.

Water Balancing

When  unit  is  one  of  many  at  the  same  water  system,  a

specialist  with  a  complete working  knowledge  of  water

systems,  controls  and  operation  must  be  employed  to

properly balance the entire system. Unqualified personnel

should not attempt to manipulate temperatures, pressures

or flow rates, as all systems have unique operating charac-

teristics and improper balancing can result in undesirable

noises and operation.

5. Operation and Maintenance

General

A  heat  pump  is  self-contained  system  that  requires prof-

esssional  maintenance  and  repair.  Other  than  replacing

filters and keeping the exterior of the unit clean as well as

the  surrounding,  the  homeowner  should  not  attempt  to

make any adjustments or repairs to the heat pump system.

A qualified licensed technician will be able to take care of

any questions or problem which may occur.
For either maintenance routine or in the event the unit is

not functioning correctly a service a company is required.

Only  a  company  with  service  technicians  qualified  and

experienced in both heating and air conditioning should be

permitted to service the systems in order to keep warrant-

ies in effect. The service tech may call the factory if assist-

ance is required.

After start-up the air conditioning system requires a main-

tenance schedule.
A  maintenance  program  similar  to  the  example  given  be-

low  should  be  scheduled  for  routine  maintenance  of  this

equipment in order to provide continued efficient and re-

liable operation for the owner.

Maintenance Schedule

Monthly:

Check cleanliness of filters and replace if necess-

ary.
