Installation
Ventilate the Spray Booth
The spray booth must have a ventilation system.
Electrically interlock the gun fluid supply with the
ventilators to prevent gun operation any time that the
ventilation air flow falls below minimum values. Check
and follow all local codes and regulations regarding air
exhaust velocity requirements. Verify the operation of
the interlock at least once a year.
Configure Gun and Manifold
The gun is supplied with an internal fluid plug and seals
(5, 6, 7). To use the gun in a circulating system, remove
the internal plug. In a non-circulating system, leave the
plug in place to minimize flush time.
Circulating System
1. Apply anti-seize lubricant 222955 to the threads and
mating faces of the manifold (101) and the elbows
(107), supplied unassembled.
2. Install the elbows (107) in both fluid ports of the
manifold (101).
3. Connect the fluid supply hose to one elbow and the
fluid return hose to the other. The manifold fluid
ports are reversible.
4. Install the gun on the manifold, using the four
screws (17). Start the threads of all four screws, and
tighten the front two screws first, and then tighten
the back two screws to 65 in-lb (7.3 N•m).
Non-circulating System
1. See F
IG
. 1. Apply anti-seize lubricant 222955 to the
threads and mating faces of the manifold (101), plug
(109), and elbow (107), supplied unassembled.
2. Install an elbow (107) in one fluid port of the
manifold (101), and a plug (109) in the other port.
3. Install the internal plug (5) in the gun fluid port on
the same side as the manifold plug.
4. Connect the fluid supply hose to the manifold elbow
(107).
5. Install the gun on the manifold, using the four
screws (17). Start the threads of all four screws, and
tighten the front two screws first, and then tighten
the back two screws to 65 in-lb (7.3 N•m).
Do not operate the gun unless ventilating air flow is
above the minimum required value. Provide fresh air
ventilation to avoid the buildup of flammable or toxic
vapors when spraying, flushing, or cleaning the gun.
Interlock the gun fluid supply to prevent operation
unless ventilating air flow is above the minimum
required value.
