ALTAIR II -
Electric Boilerless Convection Steamer
CAUTION
Flush incoming water line prior to connecting to steamer. Debris in water lines may cause solenoid valve to
malfunction. If solenoid valve is stuck open water must be turned off at the source.
NOTICE
Water level probes will not sense water level if steamer is connected to a de-ionized water or reverse osmosis system.
WARNING
The water may be very hot. It is advisable to allow the water to cool down before draining. Leaving the door open
will aid cooling.
WARNING
Failure to keep the overflow standpipe and drain pipe clear and unobstructed may result in an unsafe condition.
WARNING
The steamer must be level in order for the water sensors and overflow outlet to function properly.

Water and Drain Connection
Water Hookup
: Steamer requires 1/2” water line. Termination is 3/4” male garden hose connection. Make sure waterline is
flushed to remove grit and soldering particles prior to connecting steamer. Dirty water lines may affect solenoid operation.
Double (stacked) compartment steamers require separate water connections, which may be manifolded. Inadequate
water supply may cause one steamer not to fill properly when both steamers are turned on at the same time. If that
happens turn on one steamer a few minutes after the first.
Appliance is to be installed with backflow prevention in accordance with applicable federal, province and local codes.
Do not connect to de-ionized water. Probes will not sense the level of the water. Recommended water pressure is 30 – 35 lbs.
Recommended Water Quality
: Refer to Service Connections in this Manual for the recommended water quality criteria.
Rear Drain
: Make sure the 1” rear drain is plumbed to a floor trough or air gap drain. Customer supplies plumbing.
However, one 90° elbow is shipped with the steamer to be used as needed. The drip trough located under the door is
plumbed to the main drain internally.
The drain piping must consist of temperature resistant material, greater than 160°F, and be of adequate diameter not to
cause flow restriction. Improper materials may deform and cause restrictions, thus affecting performance.
Overflow Pipe
: An overflow incorporated into the reservoir drain standpipe allows water to flow into the drain line out the
back of the steamer in case of a waterfill malfunction.
Leveling
Once the legs have been installed and the steamer has been placed in its final location, the unit must be leveled. This is
done by turning the base of the leg. Use the top of the steamer casing as a reference. It is recommended to use a level to
ensure proper installation.
