2. Install line connections to valve so its flow
arrow corresponds to flow direction on flange.
On valves with solder connections remove cap
screws, power assembly, cage assembly and
gaskets prior to brazing.
3. Assemble valve after brazing, according to Fig
1, making sure that lugs of spring carrier line up
with slots inside power assembly.
4. Tighten

diaphragm failure, flooding or starving. Use of
an ALCO Filter Drier is strongly recommended.
2. Protect valve against excessive vibrations as it
may result in bulb tubing breaking.
Leakage test:
After completion of installation, a test pressure must
be carried out as follows:
- According to EN378 for systems which must
comply with European pressure equipment directive
97/23/EC
- To maximum working pressure of system for other
applications
Warning:
- Failure to do so could result in loss of refrigerant
and personal injury.
- The pressure test must be conducted by skilled
persons with due respect regarding the danger
related to pressure.
