Sea Frost BG 2000 Procedures for Working with R-404a, Access to the System Service Ports

Page 19

PROCEDURES FOR WORKING WITH R-404a

1)A new uncharged system must be evacuated before adding R-404a.

2)An R-404a system must only be pressurized with R-404a or nitrogen.

3)Only service tools dedicated to R-404a are to be used. No parts, tubing, fittings, receivers, dryers, service gauges, or any refrigerant carrying components may be fitted to a R-404a system from a used system or from a CFC based system. Damage caused by the use of parts not supplied by Sea Frost for a R-404a system will cancel all claims against Sea Frost.

4)No oil is to be added to the BG 2000 system but polyolester oil supplied by Sea Frost, labeled and capped for BG 2000 use. No oil is to be added to a system without prior consultation with Sea Frost.

5)The oils used in R-404a systems are moisture sensitive (hydroscopic). Do not leave any tube end or component connection open to air while assembling the system. Be sure to use only new capped copper tubing and be sure to cap the copper coil after cutting it.

ACCESS TO THE SYSTEM: SERVICE PORTS

The service ports are two small capped valves. The low-pressure valve is mounted on the BG 2000 compressor. The high-pressure valve is mounted on a copper tube in the cabinet behind the RFD. (See drawing pg. 33) The ports are standard ¼ inch male flares with core valves. Hose connections must have the proper core depressor insert in it to access the system.

Be sure the caps are installed tightly after charging or service.

NOTE: THIS SYSTEM IS DESIGNED FOR R-404a. IT MUST BE CHARGED WITH R- 404a ONLY. ONLY DEDICATED R-404a GAUGES AND EQUIPMENT ARE TO BE USED. ANY CONTAMINATION FROM CFC BASED REFRIGERANTS WILL DESTROY THIS SYSTEM.
