Charging Jacket

OPERATOR'S MANUAL

Model S365

WARNINGS

Only use on TXV systems using
either R410A or R22.
Ensure the system is powered
OFF before installing the Charg­ing Jacket.
Severe injury can occur if the fan
turns ON before hooks are se­curely fastened towards the top
of the condenser.
Wear eye protection.
Only use when the ambient dry
bulb temperature is between
37°F and 70°F (3°C to 21°C.)
Using outside of this range can
damage the air conditioner/heat
pump.
Head pressure of the system
needs to remain within the
following safe ranges to avoid
damage to the compressor or
other equipment:

R22: 55psig to 300psig
R410A: 97psig to 500psig

Stop the system if the head pres­sure approaches these limits.

Description

HVACR technicians typically
cannot charge a cooling system in
cold weather. The cold temperature
removes too much heat from the
condenser coils.

The Charging Jacket from Fieldpiece
Instruments allow you to charge a TXV
system when ambient temperatures
are between 70°F and 37°F.

It works by restricting the fan outlet
of the condenser, in eect raising the
temperature within the condsenser.
This is a more eective method than
blocking the incoming air to the
condenser coil .

Look professional and increase
your amount of possible jobs. No
more trash bags or cardboard! Do it
the right way.

Maintenance

Hand wash with cold water and
mild detergent if needed and let air
dry. Do not machine wash or dry.

How to Use

The Winter Charge Setup may
only be used for equipment for which
the air conditioning manufacturers
approve the use of the Winter
Charge Setup. Refer to (California’s)
Energy Commissions website for
the list of split system air condition
units approved by the manufacturers
to use the Winter Charge Setup. In
addition to the requirements of this
document, manufacturers may issue
additional instructions/clarication
for the equipment and procedures to
be used to conduct the Winter Charge
Setup. These additional instruction/
clarifications are also available on
the (California) Energy Commission
website.

Setup

1 Power down the system.
2 Install Charging Jacket:

RESTRICTION STRING

A. Tighten Bungie Cinch around top
of condenser fan cage making sure
not to block the airow inlet (sides.)

B. Fasten hooks securely so that the

the fan does not eject the Charging
Jacket when the system starts.

C. Always start with the top open,

then tighten the restriction string
to restrict airow as needed.

BUNGIE CINCH

3 Make sure people and animals are

clear of the condenser, then start
the system. If using on a heat pump,

set it to cooling mode.

4 Carefully adjust the restriction

of the Charging Jacket until the
difference between the high
side and the low side pressures
is between 160psi and 220psi
(R410A) or 100psi and 145psi (R22).

Restricting airflow increases the

pressure dierence.

Check Refrigerant Charge

5 Once the system is within the

pressure dierence range, allow
the system to stabilize for 15
minutes.

6 Calculate Actual Subcooling.

(Tcondenser, saturation - T liquid line)

If your subcooling is more
than three degrees less than the
target subcooling, then you are
undercharged. (continued)

If your subcooling is more than one

HOLD

INRUSH

Displa

y

degree over the target subcooling,
you are overcharged.

EXAMPLES

Target subcooling = 12°F and your
measured subcooling is 10°F. You are
OK.

Target subcooling = 12°F and your
measured subcooling is 14°F. You are
overcharged.

Target subcooling = 12°F and your
measured subcooling is 7°F. You are
undercharged.

Please use manufacturer's target
subcooling for comparison.

Check TXV Device

7 Calculate Actual Superheat

(Tsuction - T evaporator,saturation)

8 If TXV manufacturer’s data is

available, determine the superheat
range recommended by the
manufacturer. (continued)

9 If there is no manufacturer’s data

available then a superheat between
4° and 25°F is acceptable for a TXV. If
the superheat is outside this range,
and the charge is correctly adjusted
by the subcooling method, there
may be a problem with the TXV.
