Connecting the pre-charged
refrigeration lines
Note: Before connecting the Pre-charged Refrig-
eration Lines, the Refrigeration Unit must be prop-
erly located, leveled, and the water bath filled 1"
(2.5 cm) below the drain pipe.
1. Attach low side Gauge Set to service port on
each line set to verify positive pressure within
the line set. If there is positive pressure, assume
line set is fully charged.
Note: If for any reason the lines are damaged and/
or leaking or lines are no longer charged, refer to
How To Re-charge the Line Sets.
2. Always make the connections at the Condenser
first, using the end of the Pre-charged Lines
with the valve ports.
3. Connect the Condenser side one time quick
connects (discharge and liquid) up to Condenser.
Refer to the section titled Aeroquip
Connection in these instructions.
4. Check that the sight glass clears during pull
down to verify the Line Set charge.
5. If the sight glass does not clear, attach the
gauges. Adjust the charge if necessary.
How to re-charge the line sets
Note: This procedure to be used only with dam-
aged or evacuated Line Sets or with unknown re-
frigerant type.
1. Repair any damages to the Line Sets before
proceeding.
2. With the Remote Condenser lines properly
hooked and sealed to the Condenser, evacuate
to 30 in mercury (76.2 cm mercury) for 1 hour,
using one or both Schrader ports on the service
Line Set.
3. Charge the Condenser and Line Set accordingly.
Add 0.72 oz/ft (0.067 kg/m) of Remote Line Set
(one way run distance) plus 6 oz (170 g) of
refrigerant for any size Condenser.
Example:
50 ft of Line Set
50 x 0.72 = 36 oz
36 oz + 6.0 oz = 42.0 oz (Total)
4. Connect Line Sets to the proper discharge and
liquid mating connectors on the Refrigeration
Unit using one (1) time quick connects. Refer
to the section titled Aeroquip Connection
in these instructions.
