tained and proper startup and operation procedures are followed. The following tasks should be per-
formed at the intervals stated:
1. Clean or replace chilled water strainer annually. Adjust accordingly based on purity of chilled
water.
2. Check sight glass level of receiver every 4-6 weeks. During normal operation, the level should be
at or above the second sight glass.
3. Check system for leaks every 4-6 weeks.

7.1 Fluorinated Greenhouse Gas Requirements

Stationary air conditioning, refrigeration, heat pump equipments and stationary fire protection sys-
tems in the European Community market and operating with fluorinated greenhouse gases (f-gas),
such as R407C, R134a, R410A, must comply with the F-Gas Regulation: (EC) No. 842/2006 (F-gas).
The regulation prohibits, among other actions, venting fluorinated greenhouse gases to the atmo-
sphere.
The F-Gas Regulation requires operators to use use all measures that are technically feasible and do
not entail disproportionate cost to prevent leakage of these gases, to test for leakage regularly and to
recover f-gas during equipment service and maintenance and before disposing of equipment.
Refer to the full regulation for additional details.
