A. Room Terminators (Outlets): Based on the equipment

selected, determine the recommended number of

fully open outlets from Figure 3.1.

NUMBER OF FULLY OPEN OUTLETS

5. Check that system static pressure is within acceptable

limits (minimum 1.2" WC - ,maximum 1.5" WC). You

can use a U-tube manometer to check the external sta-

tic pressure on the duct system.

1. Puncture a ¼" diameter hole in the plenum duct at

least 18" from the fan coil unit.

2. Insert the high-side manometer tube into the hole so

that the end is approximately flush with the inside wall

of the plenum, and perpendicular to the direction of airflow.

3. System static pressure should be between 1.2" and 1.5" WC.

a. If the pressure is higher than 1.5" provide additional

supply runs to increase airflow or lower the fan

speed by turning the fan speed adjustment for the

current mode of operation counter-clockwise to

reduce the static pressure.

b. If the pressure is lower than 1.2", look for leaks in

the supply plenum, restrictions in the return system

(including clogged filters) If more than the

recommended number of supply runs are installed,

you may install flow restrictors (orifices) in these

runs. If the number of runs is appropriate for the

load, increase the static pressure by turning fan

speed adjustment for the current mode of operation

clockwise to increase the static pressure.

6. Check that blower motor amp draw compares with

fan coil unit rating plate. Amp draw shown on plate is

the FLA of motor (not the actual running amps) and will

vary with the pressure and voltage.

7. Place the thermostat cooling indicator in COOL position,

which will start the outdoor unit. Let the system run at

least 30 minutes to stabilize operating conditions.

8. For outdoor unit start-up, follow manufacturer’s instructions.

9. Check that temperature drop across evaporator coil

in the indoor unit is between 20°F to 28°F.

NOTICE: Do not introduce refrigerant liquid to system

through suction port. Liquid in the suction line may

damage the compressor.

NOTICE: Before adding refrigerant to system verify

Item #5 in “System Start-up & Adjustment” section

has been performed.

10. Verify that system refrigerant is correct by measuring

subcooling at liquid service port. Subcooling should be

in accordance with outdoor unit manufacturers

recommendations..

11. Check the super heat leaving the evaporator coil

against the corresponding suction pressure from the

schrader fitting at the fan coil unit. Superheat value

should be between 9°F and 12°F.

12. If a sight glass has been installed on the liquid line at

the air handler check for the presence of flashing. If

flashing is occuring, check and adjust subcooling by

adding refrigerant.

ChARGING COOLING ONLY SYSTEMS

After start-up, allow the system to operate for

approximately 30 minutes in order to establish stable

operating conditions. Check that the temperature drop

across the evaporator coil is 20°F to 30°F. Do not attempt

to adjust the charge at ambient temperatures below 65°F.

Verify and adjust refrigerant charge based upon outdoor

unit manufacturer’s published recommendations.

Releasing refrigerant gas into the atmo-sphere is a

criminal offense.

FACTORS AFFECTING ThE BALANCE OF ThE SYSTEM

1. The minimum or recommended number of outlets

means fully open outlets. Any outlet having an orifice

would be only a percentage of an outlet.

2. For systems with average supply tubing lengths of 15

feet or less, use column A. For systems with supply tubing

lengths greater than 15 feet, use column B.

NOTICE: The number of outlets and average length of

the supply tubing has a significant effect on the overall

system performance. It is highly recommended that the

adjustment factors outlined in the SpacePak Application

Manual are accounted for prior to any installation.

B. Orifice Combinations: Should orifices be required to

balance the system (installed at plenum take-off),

refer to the combinations listed in Figure 3.2
