2.3 Install the MINI
2.3.1 Select a Location for the MINI
1. For safe and efficient operation, observe the following criteria when selecting an operating
location for a MINI
2. Transport the MINI on its pallet.
3. Passages and doors must be high enough and wide enough for a MINI and its pallet. See
Table 2-1.
4. Location selected must be capable of supporting a MINI and or optional stand. See Table 2-1.
5. The area MUST be free from and clear of combustible materials.
6. Position the MINI so it will not tip or slide.
7. To ensure that the oven functions correctly when installed, it should be placed upright and
level (horizontally). This is measured at the front and side edge of the roof. The oven can be
levelled using the adjusting screws on the stand or on the legs of table models.
Improper lifting can result in DEATH, INJURY, AND EQUIPMENT DAMAGE. Use enough workers with training
and experience lifting heavy equipment to place MINIs on supporting surfaces and lift and handle MINIs
and accessories.
Operating an out of level MINI can cause DEATH, INJURY, and EQUIPMENT DAMAGE. MINIs must be level
both front-to-back and side-to-side in all installations. NEVER operate an out of level MINI. If a MINI is
suspected to be out of level, shut it down at once and call you qualified Convotherm authorized service
agency at once.

6
8. A MINI MUST be level both front to back and side to side.
9. The ambient temperature should be within 40°F and 95°F.
10. Proper air supply for ventilation is REQUIRED for and CRITICAL to safe, efficient operation of a
MINI.
11. Operating Clearances: Sides and Rear - 3".
12. Service Clearance: Above - 20”.
13. Allow for sufficient distance if a "high heat source" (e.g. grills) is located next to the unit.

NOTICE
Using water outside the limits specified in this manual without appropriate
adjustment in the maintenance schedule voids warranty coverage.
2.4.2 Water Supply Requirements
2.4.2.1 Water Quality
1. Check the quality of supply water (described below) before designing the water supply.
2. Contact a local water treatment specialist for on-premises water analysis.
3. Minimum feed water quality requirements are listed in Table 2-3.
4. Poor water supply quality degrades MINI performance.
5. Softened or chlorinated water damages the MINI by increasing corrosion. Filtration is
required before water enters the MINI if supply water is softened or chlorinated.
6. If a water treatment system must be installed to achieve acceptable water quality, install it
BEFORE connecting the water supply lines to a MINI.
7. If analysis shows that supply water is below Minimum Water Quality:
EITHER a water treatment system must be installed in the treated water inlet line feeding
the spritzer,
OR the frequency of maintenance and cleaning must be increased beyond that
recommended in the maintenance schedule,
AND Contact your Convotherm sales representative for details on how to provide water
per Minimum Water Quality Requirements in Table 2-3, or how to increase the frequency
of maintenance and cleaning.
2.4.2.2 Minimum Water Quality Requirements – Table 2-3
Scale Forming Factors Concentrations must be:
Total Dissolved Solids 50-125 parts per million
Silica less than 13 parts per million
Alkalinity 50-100 parts per million
Hardness 50-100 parts per million (3-6 gpg)
NH2CL(Monochloramine) less than 0.2 parts per million
Corrosion-Causing
Factors
Concentrations must be:
Free Chlorine less than 0.1 parts per million
Chloride less than 25 parts per million
pH factor between 7.0-8.5
2.4.3 Water Supply System Pressure Requirements
The water supply must provide:
A minimum dynamic pressure of 35 psi (2.4 kg/cm2)
A maximum static pressure of 80 psi (4.1 kg/cm2).
2.4.4 Connect Water Supply Lines
The Installer/Owner is responsible for the correct water connection of the MINI (see next page
for included kit parts and instructions). When connecting water supply lines observe the
following instructions, and all other applicable national, state, and local codes and regulations:
1. Connect the MINI to COLD POTABLE WATER

13
2. Never connect the MINI to HOT WATER! The condenser system will not work properly if
connected to HOT or WARM water.
3. The water supply must have a minimum dynamic (flow) pressure of 35 psi (2.4 kg/cm²)
and a maximum static pressure of 80 psi (4.1 kg/cm²).
4. If the static pressure is above 80 psi, a pressure regulator must be used and set at
approximately 50 psi. Pressure above 80 psi can damage solenoid valves.
5. MINIs have two connection points for incoming water. See Figure in section 4 on page 11.
6. Water supply must meet the minimum requirements shown in the Warranty and Table 2-
3. Install a water treatment system as needed.
7. Installation Requirements:
a. Apply non-hardening pipe thread sealant to all the threaded connections except the
¾” GHT Female (Garden Hose Thread or National Hose Thread) connections at the
Water Connection. GHT or NHT connections do not require pipe thread sealant.
b. Install a manual water shut-off valve (not provided) between main water supply lines
and MINI supply lines.
c. This may require the installation of a check-valve (or other approved anti-backflow /
anti-siphon device) (not provided) in all supply lines in accordance with and as
required by local, state, and national health, sanitation and plumbing codes.
d. Check local codes to determine exactly what type of anti-backflow / anti-siphon device
is necessary to meet local requirements.

schedule and of a material suitable for sustained operation at 140°F.
Notice: Joining clamps may be used to connect same size or larger size drain to the existing drain.
The following restrictions and requirements are critical to the safety of personnel and equipment, and
must not be violated under any circumstances:
1. Do NOT connect the MINI drain connection to any drain material that cannot sustain 140° F.
2. Do NOT connect drains from any other equipment to the drain line of the MINI.
3. Do NOT connect the drain outlet extension line directly into a floor drain or a sewer line.
4. Do NOT connect the MINI drain directly to drains or to the plumbing of any other equipment.
5. The drain line must be free air vented, have gravity flow from the MINI, and terminate outside the
perimeter of the MINI.
6. Improper installation of drain outlet lines voids the MINI warranty.
7. The drain lines must be installed in compliance with the Food Service Sanitation Manual of the Food and
Drug Administration (FDA) and any other applicable national, state, or local codes and regulations.
8. This equipment is to be installed to comply with the applicable federal, state, or local plumbing codes.
9. Do NOT install the MINI directly over a drain. Steam rising up out of the drain will adversely affect operation,
hamper cooling air circulation, and damage electrical and electronic components.
10. The total length of drain and number of bend fittings required to reach the open drain determines the
drain size used to extend the drain line to an open drain.
If the drain outlet extension requires 6 feet or less of drain,
and no more than two elbows are required, 1 1/2-inch ID
drain and fittings are acceptable.
If the drain outlet extension requires 6 to 12 feet of drain, or
requires three elbows, then 2-inch ID drain and fittings are
required.
The drain line must have gravity flow from the MINI drain
outlet to floor drain.
Do NOT install a trap in the drain line.
11. Free air venting requires minimum 1” clearance between the end
of the drain line and the top of the floor drain.
