Digital Scale Operating Instructions
NOTE
: All objects should be removed from the
scale platform.
After recovery is complete:
1. Place the scale on a level, rigid surface.
2. Press the power button key to turn the unit
on. Wait for the LCD to display a zero-weight
reading.
3. Press the unit selection key, LB/KG, to select
LB (pounds and ounces).
4. The scale is now ready for weighing.
NOTE : Change batteries when all segments of
the battery level indicator are off.
Refrigerant Charging
Caution
: Carefully place the R-410A refrigerant
cylinder on the scale platform to avoid subjecting
the scale to mechanical shock.
1. Place the R-410a cylinder on the digital scale
platform and allow the liquid refrigerant to
come to rest in the tank.
2. Connect the charging hose to the cylinder.
3. Bleed the air out of the hose.
4. Press the TARE key (LCD will now read zero).
5. Open the R-410A cylinder valve. The LCD
will indicate the amount of R-410a refrigerant
being transferred in negative numbers.
6. Close the R-410A cylinder valve when the
desired charge amount is displayed.
Manifold Gauges
The R-410A system requires higher pressure
gauges. Be sure that R-410A is printed on the
face of the gauge being used.
A normally operating R-410A system with a
condensing temperature of 120° and 45°F
evaporator saturation temperature has a high
side pressure of approximately 418 psi, and a low
side pressure of approximately 130 psi.
Low Side Pressure Gauge
The inner dial of the low side pressure gauge
reads the temperature in °F from 80 to -40.
The outer dial reads pressure in psi from 0 to 500.
The outer dial also reads vacuum in Inches Hg.
High Side Pressure Gauge
The inner dial of the high side pressure gauge
reads the temperature in °F from 0 to 160.
The outer dial reads pressure in psi from 0 to 800.
Charging Procedures
IMPORTANT : The R-410A system can only be
charged on the high-pressure side of the system,
and only with liquid refrigerant.
The amount of refrigerant used in the charge
is measured by weight with a digital scale. If
the R-410A cylinder does not have a dip tube,
the cylinder must be turned upside down when
placed on the digital scale.
A 15-inch vacuum is required in the sealed
system before the charging process begins. This
permits the system's compressor to remain off
during the charging process. Pressures are
monitored by manifold gauges.
