SPECIFICATIONS • INSTALLATION
NEMA 4 ENCLOSURE: Model available.
APPROVALS:
Underwriters Laboratories Inc. Listed: File No. MN1639,
Guide No. YI0Z.
Factory Mutual Approved: Report Nos. 20835 and 24061
International Approval Services (IAS), a joint venture of
AGA and (CGA): Design Certified.
Industrial Risk Insurers: Acceptable.
CAUTION
1. Disconnect power before connecting wiring.
2. Assure that wiring complies with applicable
electrical codes and ordinances.
3. Be sure that power supply is the same as that
stamped on the nameplate of the device.
4. Be sure only a trained, experienced, flame safe-
guard control serviceman installs or services
this device.
5. Assure that loads connected to the auxiliary
switch, if used, do not exceed the ratings given
in the Specifications section.
6. Do not attempt to use the V9055 with one of the
adapters that connects the V4055 Actuator to
the older V5034 Valves. The adapter is for use
with the V4055 only. The V9055 cannot be
used with a V5034 Valve. When replacing a
V9034 Actuator with a V9055, the V5034 Valve
must be replaced with a V5055 Gas Valve.
7. Connect terminals R, W, and B only to Series 90
proportioning controller. Do not apply any volt-
age to these terminals.
8. Avoid mounting actuator upside down if water
is likely to drip on it. In this position, water can
become trapped in the electronics compartment.
VALVE INSTALLATION
The actuator is mounted directly on the V5055 Valve
after the valve is installed in the gas supply line. Refer to the
instructions packed with the V5055 Valve for details of
installation. When installing the valve, be sure that:
1. Sufficient clearance is left for installation and service
of the actuator.
2. Ambient temperatures at the valve location will re-
main within the rated ambient range.
3. The position of the valve permits hookup to the
damper if one is controlled.

ACCESSORIES:
133568 Auxiliary Switch
7616BR Crank Arm
135796 Wrench
133569 Proof-of-closure Switch Bag Assembly. Must be
used with V5055C or E.
Q5055A1001 Adapter Assembly—Adapts ITT General
V710 Gas Valve to accept Honeywell Gas Valve Ac-
tuators. Replaces ITT AH8 Gas Valve Actuator.
203422C Adapter Board—Used to control V9055 Ac-
tuator with 4-20 dc mA input.
IMPORTANT: When a damper crank arm is used with a
NEMA 4 actuator that is exposed to ice or sleet, a
suitable shield must be installed to prevent ice or sleet
buildup.
INSTALL ACCESSORY SWITCHES (IF NEEDED)
An spdt switch may be installed to operate an auxiliary
load of up to 1/2 hp. The switch may be adjusted to operate
at any point in the valve stroke. A proof-of-closure switch
may also be installed. The proof-of-closure switch must be
used with the V5055 C,E (two seals) Valve to provide valve
seal overtravel interlock.
The spdt proof-of-closure switch is installed to make or
break a circuit when the valve is in the closed position. The
switch is not adjustable.
NOTE: Mark the actuator or valve to indicate any changes
made.
To install the switches, proceed as follows:
1. Remove the actuator faceplate (two screws).
2. Remove the silver-colored barrier to expose the actua-
tor stem.
3. Insert the auxiliary switch in the position indicated in
Fig. 3. Fasten with two screws through the actuator base.
4. Insert the proof-of-closure switch in the position shown
in Fig. 3. The proof-of-closure switch mounts against the
side of the actuator housing. The mounting holes are spaced
to mount the switch only in the correct position. Fasten with
two screws through the actuator base.
5. If only one switch is used, install the narrow barrier
included with the switch in the unused space.
6. Mount the actuator before making wiring connections
and adjustments to the switch.
MOUNT AND ADJUST DAMPER CRANK ARM
IMPORTANT: When a damper crank arm is used with a
NEMA 4 actuator that is exposed to ice or sleet, a
suitable shield must be installed to prevent ice or sleet
buildup.
