Evacuation, complete with pressure drop test using vacuum
gauge can be performed as well as charging system. Manifold
will hold vacuum of 25 microns or better without leaking.
EVACUATION:
1. Close Valves A and B . Valve A isolates Port #2
from system. Valve B isolates system from pump.
2. Install directly onto intake of your pump via the 3/8”
flare swivel coupler #1. Note: Do not wrench coupler.
Finger tightening will seal this connection for deep
vacuum.
3. If using vacuum gauge install to Port #2 using
4
A
O-ring coupler. If vacuum gauge is not used, cap
port.
4. Using deep vacuum flexible metal hoses with O-ring
couplers make connections at Ports #3 and #4 and
to the suction and discharge service valves on the
unit to be evacuated. This allows you to evacuate
from the high and low side of the system. Note: Unit
should be purged of refrigerant prior to connection.

5. Open suction and discharge service valves and
manifold Valve B . Turn on pump and open Valve A if
using micron gauge. Evacuate to manufacturer’s
recommendations and close Valve B . This isolates
the pump from the system to perform pressure drop
test using micron gauge.
TO CHARGE SYSTEM:
1. Close Valve B . This will be closed after pressure
drop test if using vacuum gauge. Remove gauge
connection.
2. Connect refrigerant line to Port #2 . Connection at
port should be loose. Open refrigerant supply. When
air is purged, finger tighten connection at Port #2
and open Valve A to charge system.
