1. Built in manifold gauge set
2. Recovery/recharging unit
Other recovery systems are available where the
manifold gauges are not an integral part of the ma-
chine. When this type of equipment is used a sepa-
rate manifold gauge set must be used.
The following is a summary of the steps for dis-
charging the system using a recovery/recycling unit.

WARNING
Never discharge refrigerant gas into the atmos-
phere. Always wear safety goggles and gloves
when working with refrigerant. Only use authorized
refrigerant tanks.
IMPORTANT: always follow the manufactures in-
structions when operating recovery equipment.
1. Run the vehicle's air conditioning system for a
few minutes.
2. Set up the recovery unit following manufactur-
er's instructions. Ensure that the units red (high
side) hose is connected to the high side (dis-
charge) fitting and the blue (low side) hose to
the low side (suction) fitting.

3. Low side (suction) service valve (blue hose)
4. High side (discharge) service valve (red hose)
NOTE: if a unit requiring the manifold gauge set is
being used, the low and high sides of the manifold
set are connected to the low and high sides of the
loader backhoe air conditioning system. The hose
from the recovery unit is then connected to the man-
ifold centre port.
3. To recover refrigerant, open both high and low
side valves on the control panel or the valves on
the manifold gauge set if being used.
4. Open the valves labelled "gas" and "liquid" on
the recovery unit refrigerant tank.
5. Plug in the unit's power cord.
6. Operate the recovery system in accordance with
the manufacturers instructions.
The compressor will shut off automatically when the
recovery is complete.
