GENERAL INSTALLATION
Note
: Refer to FM-
916 Mobile “E” Cylinder Stand Installation
and Instructions for connecting gas supply to the flowmeter
and cylinder installation to mobile stand.
Installation of Rubber Goods (Figure 2)
1. Slide the breathing bag opening over the outside
diameter of the bag mount.
2. Slide the 22mm fresh gas connector from the scavenger
into the breathing tube connector.
3. If an accessory, such as the Scavenger Control Valve is
used, connect it following the instructions supplied with
it.

Installation of Rubber Goods.
Connection of Oxygen
– Nitrous Oxide
For safety reasons, gas connections are color-coded and
mechanically indexed using the Sleeve Indexed System
(SIS) to prevent accidental cross connection. SIS female
hexagon fittings are standard for both hoses.
1. Connect the SIS female hexagon fitting of the nitrous
oxide hose to the male SIS, N
2
O INLET, fitting on the
back of the mixer head (see Figure 3). Hand-tighten and
then finish tightening with a 7/8” inch open end wrench
(approximately 1/8 turn).
Do not over-tighten
.
2. Connect the SIS female hexagon fitting of the oxygen
hose to the male SIS, O
2
INLET, fitting on the rear of the
unit (see Figure 3). Hand-tighten and then finish
tightening with a 11/16” inch open end wrench
(approximately 1/8 turn).
Do not over-tighten.
Hoses
Hoses are manufactured for connection to the gas source in
various configurations:
Quick Connect fittings are designed for rapid “no tool”
connections with corresponding male / female fittings or
outlet stations. Refer to the individual manufacturer’s
instructions for specific connection procedure.
SIS to SIS hoses are designed primarily for portable
systems. The gas source (male) SIS fittings are located on
the regulators on the cylinder mount block provided with the
portable units. Connect the DIGITAL MDM® mixer to the
cylinder mount block using the appropriate nitrous oxide
hose and the oxygen hose.

Connection to the back of unit.
Installation of Power Cord
Insert the power cord into the input connector on the rear of
the unit (see Figure 4).
WARNING:
For safety a Protective Earth
(ground) connection must be made through
power cord 3rd wire or Ground Lug (see Fig. 4).
WARNING:
Not providing a valid Protective
Earth (ground) connection can result in the risk
of electric shock.
