Before operating the RG5410A recovery unit,
read the following
ƽ
1. RG5410A IS APPROVED FOR USE WITH THE
FOLLOWING CATEGORY III, IV and V REFRIG-
ERANTS (Per ARI 740):
R-12, R-22, R-134A, R-401A, R-401B, R-401C,
R-402A,R-402-B,R-404A,R-406A,R-407A,R-407-B,
R-407C, R-407D, R-408A, R-409A, R-410A,R-411A,
R-411B, R-412A, R-500, R-502, R-507 and R-509
2. A FILTER must always be used and should
replaced frequently. We recommend that a clean
filter be used for every service job.
Failure to use a filter will invalidate your warranty.
The use of a filter will greatly reduce the risk of
damage to your RG5410A, by preventing
foreign material from entering the unit.
3. Each filter should be labeled and used exclusively
for one type of refrigerant only.
4. Always open service and cylinder valves slowly.
This allows rapid control of the flow of gases if
there is any danger. Once it is determined that
there is no danger, the valves can be opened
fully.
5. Always isolate large amounts of refrigerant and
close off valves after use, so if a leak should
develop anywhere in the system, the refrigerant
will not escape.
6. Keep all connections to the refrigeration system
thoroughly dry and clean. If moisture enters the
refrigeration system, it is likely to cause consider-
able damage.
7. Promax strongly recommends the use of the
optional 80% Capacity Shutoff Kit (p/n KT-5001).
When installed and used with a recovery tank that
has an internal float switch, the RG5410A will
shut down automatically when the tank is 80% full.
Your RG5410A is pre-wired from the factory for
this kit. Note: The RG5410A is also available in
model RG541OA-KT, with the 80% Shutoff Kit
installed direct from the factory.
8.
ƽ
A CAUTION: Use only authorized refillable
refrigerant recovery tanks. Federal regulations
require refrigerant to be transported only in
containers meeting DOT spec. 4BA or 4BW.
NEVER use a standard disposable 301b. ta, .1% (the
type of container in which virgin refrigerant is sold) to
recover refrigerant.
9.
ƽ
A scale must be used to avoid overfilling the
storage tank. DO NOT OVERFILL. Tank is full at
80% volume. Tank may explode if filled more than
80% due to liquid expansion. Below is a repre-
sentative sample for R-22 refrigerant:
Note: Promax strongly recommends the use of the
ADS-100 Refrigerant Scale for monitoring tank
capacity.
10. Your RG5410A has two Internal Pressure
Shut Off switches, a standard 400psi and
a 550psi (when the High Pressure (R410A)
switch is engaged). The shut off switches will
automatically reset after the pressure drops
below 200 psi.
ƽ
WARNING: The Internal Pressure Shut Off
Switches do not prevent tank overfill. If your system
shuts off on high pressure and is connected to your
tank, you may have overfilled your tank and created
a very dangerous situation! Take immediate meas-
ures to relieve any high pressure and/or tank overfill.
11. When recovering large amounts of liquid, use the
"Push/Pull method (see diagram on page 13).
ƽ
CAUTION: When using the "Push/Pull" method,
once the "Push/Pull" siphon is started, it can contin-
ue and overfill the storage tank even if the tank is
equipped with a "shut off" float sensor. The siphon
can continue even after the machine is turned off.
You must manually close the valves on the tank and
the unit to prevent overfilling of the recovery tank.
12. Always operate the unit on a flat level surface.
13. To achieve the deepest final vacuum, use the
tank cooling method to lower the head pressure
on the recovery tank. (See Pages 13 & 14).
Repeat as necessary to achieve the desired
vacuum level.
