Congratulations! You have just purchased the latest in cooking technology, the new moisture+from Garland.

Garland is an established leader in innovative oven technology, and has manufactured this multifunction oven with the operator in mind. The moisture+provides function not previously available in a convection oven. Your moisture+will operate as three pieces of equipment: a convection oven, a humidified baking oven, and a humidified cook & hold oven. Additionally, the optionalwet-cleanwater spray attachment allows you to easily spray down the oven interior during cleaning. Garland, long known for offering the “best baking” convection ovens available, adds the moisture+ to its model line to provide you, the user with, a workhorse oven that will provide years of useful service.

Like any other fine, precision built appliance, your moisture+oven should be given regular care and maintenance. Periodic inspection by your dealer or a qualified service agency is recommended. When corresponding with the factory or your local authorized factory service center regarding service problems or replacement parts, be sure to refer to the particular oven by the correct model number, (including the prefix/suffix letters and numbers), and the warranty serial number. The rating plate affixed to the oven contains this information.

PREPARING THE OVEN FOR INSTALLATION

Legs and Casters

NOTE: If you will be installing an open base kit, please skip to the next page and proceed with the steps listed under “Open Base Assembly..”

1.(See Figure 1..).. At the bottom end of each leg, install the bullet foot insert or caster insert.. The fit of the insert to the leg is intended to be snug, tap them lightly into place with a mallet or rubber hammer..

Install two #5 x 1/4” self-drilling,thread forming screws into each caster insert..

2.Screw a caster into the insert on each of the four legs.. The caster must be inserted at least three full threads to properly support the oven.. A 1” (25mm) open-endwrench may be needed to properly install the casters..

OR

Using your fingers, screw the ends of the bullet feet into the leg clockwise until they are at their shortest length..

3.Carefully tip and lower the oven onto its left side so you can easily reach the bolt mounting locations in the base..

4.The four holes in the top of each leg or in the top plate of double stack casters will match the bolt locations at each corner of the oven base..

You will need four 3/8-16x 1” hex head bolts and four 3/8” flat washers to mount each leg.. Align the leg to one of the matching bolt holes on the base and insert a bolt with washer..

Install the remaining three bolts and finger-tightenall four before using an 11/16” wrench to fully tighten them all.. Be sure to tighten all four bolts for each leg or caster.. When installing casters, make sure the two casters with brakes are installed at the front of the oven..

5.Carefully return the oven to an upright position.. Ensure the two legs/casters that touch the floor first when you raise the oven are blocked and chocked so they do not slip away..

6.It is very important to use the adjustable bullet foot inserts in leveling the unit.

7.If you have installed casters, be sure to install the restraint bracket on the lower left corner of the rear of the oven using two #10 x 3/4” sheet metal screws..

PREPARING THE OVEN FOR INSTALLATION

Open Base Assembly

Use the following sequence of steps to assemble and install the open base accessory..

1.(See Figure 2..).. Align the rack guide upper support to the corresponding holes in the oven base.. Fasten using three #10 x 3/4” machine screws on each side of the oven..

2.At the lower end of each leg install an “L” shaped support clip using a #10 x 3/4” sheet metal screw.. Do this before fastening the leg to the base..

3.Install legs to the bolt holes at the front and rear of the base on the oven’s left side, (side lying on the floor).. If installing casters, be sure to install a locking caster on the front leg.. Refer to the section, “Legs and Casters,” on the previous page for installation details..

4.Fasten the open base panel in place on the brackets of the two legs already installed, using one #10 x 3/4” sheet metal screw in each corner..

5.While supporting the open base panel, install the rightside legs as in step 2.. Ensure the caster with a brake is at the front of the oven.. Fasten the remaining two corners of the open base panel to the other two legs just installed..

6.Carefully return the oven to an upright position.. Ensure the two legs/casters that touch the floor first when you raise the oven are blocked and chocked so they do not slip away..

7.Install the rack guides in one of the two available positions.. The inner position sets the guides at a width to accommodate oven pans.. The outer position sets the guides at a width to accommodate wire oven racks.. To

attach, insert the longer straight end at the top of the rack guide all the way into the mounting hole, then align the bottom holes and lower the rack guide into position..

8.It is very important to use the adjustable bullet foot inserts in leveling the unit.

9.If you have installed casters, be sure to install the restraint bracket on the lower left corner of the rear of the oven using two #10 x 3/4” sheet metal screws..

PREPARING THE OVEN FOR INSTALLATION

Stacking Two Ovens

1.Follow the instructions in the section entitled, “Legs and Casters,” on page 5.. Then resume at step 2 on this page to complete the stacking process..

2.Move the lower oven as close to the final installation point as possible, leaving enough space around the oven to allow access for the remaining installation steps.. If casters have been installed, apply the brakes on the two front wheels..

3.Carefully raise the upper oven and place it on top of the lower oven, aligning the four lower corners of the upper even to the four upper corners of the lower oven..

4.At the rear of the stacked ovens, install the stacking bracket using six 1/4-20x 1” hex head bolts with lock washers and nuts.. Firmly tighten all six nuts/bolts to secure the ovens together..

5.Remove the outer flue vent from the right top corner of the rear of each oven, saving the screws..

6.If they are not already fastened together, assemble the two parts of the interconnecting flue channel included in the stacking kit, using six #10 x 3/4” sheet metal screws..

7.Fit the channel assembly over the flue vent area of each oven and fasten using the screws removed in step 5..

8.If you have installed casters, be sure to install the restraint bracket on the lower left corner of the rear of the upper oven using two #10 x3/4” sheet metal screws..

9.If your installation requires one common gas inlet for both ovens, use the piping included with your stacking kit to assemble the interconnecting gas pipe.. Refer to Figure 3..

NOTE: It is recommended, when stacking a Moisture + Oven with a Master Convention Oven, that the Moisture + be located on the bottom..
