Groundsheet
•Identify the two tent components –the ground sheet and the tent. The groundsheet is grey
in colour and has a zipper around the outside perimeter.
•Take the groundsheet and spread it over a clean, flat surface (the installation site) with the
zipper facing upwards. - Figure 1
•Take care not to walk on the groundsheet as any contamination will have to be wiped down
later from inside the tent.
•Note the zipper that goes across the width of the groundsheet towards one end. This is the
gowning room end and should be oriented towards the personnel entrance for the
installation site. i.e., don’t put it up against a wall! The HEPA FFU and stand should be placed
at the opposite end with its front ‘Partition’ feet aligned with the edge of the groundsheet.
•Clean the groundsheet with IPA alcohol solution or similar.

HEPA fan filter unit (FFU) frame
Identify the FFU frame components.
Self-assembly flat pack
The frame is made from 30mm aluminium section joined with union connectors. Assemble the
frame as shown below. The HEPA FFU stand is made up of two A-Frames and 3 joining cross bars.
Ensure that the two CAM Brackets are facing out, ready to bolt into the FFU. The rear feet are
adjustable to ensure a steady base for the FFU. The front ‘Partition’ feet extend to meet the edge of
the groundsheet and give the stand additional stability. Ensure all union connectors are correctly
fitted and tightened.
Now place the FFU onto the frame with the pre-filter to the rear and the HEPA filter to the front of
the frame. Align the front of the FFU with the front of the frame. Adjust CAM bracket position as
required to ensure they meet the rear of the FFU and line up with the holes on the rear of the HEPA.
Ensure the pre-filter is fitted into the intake flange. Power up and check that the fan is working then
disconnect.

Tent top section
•Take the top section of the tent and lay it out on top of the groundsheet. Check for the FFU skirt
(large rectangular hole in the end wall), this is to be placed at the FFU end - opposite end of the
groundsheet to the gowning room. Now locate the perimeter zipper starting point –usually on
the left-hand corner of the FFU wall as viewed from behind the FFU. -Figure 2
•Zip the tent and the groundsheet together around the perimeter. Be careful not to trap the tent
material in the zipper. -Figure 3
•At the FFU end, locate the sides and top of the FFU skirt. These 3 sections have Velcro attached.
Fold the Velcro outwards to avoid it connecting to the Velcro on the FFU until you are ready.
•Locate the bottom FFU skirt. This is part of the skirt nearest the ground with no Velcro attached.
•Two people should take hold of the bottom FFU skirt. This needs to sit between the FFU unit and
the FFU frame (no Velcro required –this arrangement acts as a pressure relief in the event of
accidental over-inflation). Carefully lift the front edge of the FFU off the frame, push the bottom
skirt underneath the Filter so that it becomes sandwiched between the FFU and the frame the
FFU when it is lowered back down (Keeping a foot on the cross leg of the frame whilst undertak-
ing this procedure helps to steady the frame).
•Fix the HEPA to the stand with the supplied ¼-20 screws through the CAM brackets on the stand.
•Take the top corner of the FFU skirt. With the Velcro still folded back, position the two corners of
the FFU Skirt onto the FFU. Then simply fold back the top and sides so that the Velcro connects.
Apply pressure evenly all the way around to ensure a firm connection is made.

At the personnel entrance end of the tent, there are two outer zips for the entrance / exit. There are
also two inner zips within gowning room for cleanroom entrance. Ensure that these inner zips are
fully open. It is advised these remain open to allow airflow into the gowning room.
• Close the outer zips are closed for a faster inflation.
• Power up the fan with the fan control set to Full (Marked “High” on the FFU). The tent will start to
inflate.
NOTE - Be aware of over-inflation as this could damage the fabric or the FFU. There are two ways to
control the airflow; The fan control and the zips. Balance the air coming into the Clean Tent with the
air exiting through the entry zips.
• As the inflation can happen quickly, it is advised to have one person at the entrance end (to open
the zips) and one person to control the FFU.
• Whilst inflating, regularly check that material is free from obstructions or external objects which
could result in damage.
• As soon as the gowning room has half inflated, open the two entry zips by 300mm (to the Velcro
tabs) and turn the dial of the fan control to Low - the corners of the Clean Tent should be flat on the
floor and you should be able to push the clear side of the Clean Tent in by 100m with little
resistance.
IMPORTANT - For safety reasons (for instance in the event of a power failure), a secondary means of
support is essential. We provide a suspension cord system that should be attached to a suspended
ceiling or other suitable structure. If suitable suspension is not readily available, an optional frame
structure can be supplied.
Please note that the ceiling/structure should be capable of carrying a load a shown in the table
below.

Suspended ceiling
Ceiling clips are the standard method of adding the secondary support with the benefit of not
impinging on floor space.
Anchor points are placed onto the ceiling grid between the support loops on the tent roof/ wall
seams.
Tie the Bungee off at a corner loop and then thread through alternating ceiling anchors and tent
loops. Tie off allowing for some tension in the bungee.

Frame structure
The frame structure offers an alternative option for secondary support if the tent is positioned in an
area without an accessible suspended ceiling.
Assembly of the frame structure should be carried out before positioning and inflating the tent as it
is difficult to move once fully assembled.
Follow the instructions in the following sections for assembly and erecting of the frame.
With the frame structure complete follow the instructions in the previous sections for the tent
assembly and inflation.
Take one end of the black bungee cord and tie it off on one of the top corner loops at the FFU end of
the tent.
Pass the cord between the tent loops and over the frame structure until you have completed the
two sides and front of the Clean Tent. Tie off the bungee on the final loop.

Frame structure assembly
Assemble the 30x30mm legs with an adjustable foot at
one end. With the four screws in the T-Bars loosened,
slide the T-bars across so half is inserted in each
section. With sections held tight together tighten the
screws.
Assemble the 50x30mm end and side bars in the same
way. The lengths of the 50x30mm sections may vary –
the shorter lengths are used for the end bars and the
longer lengths used for the side bars. Lengths with
Union connectors pre-fitted should be at the end of
each assembled side and end bar.
Fit legs to the end bars to form a goal post. The
assembled top bar should have a union fitted at either
end. Loosen the union enough to allow it to slide into
the leg. Ensure the sections are aligned and tighten
the union.

Fit the corner braces. With the T-Nut on the angle
bracket loosened, rotate the T-nut and insert it into
the slot in the section. With the T-nut in the slot,
loosen it further, then tighten gradually, and at the
correct depth the T-nut should rotate 90 degrees in
the slot and form a secure connection. Take care to
ensure the T-nuts are fully rotated and firmly locked
in-place after tightening.
Correct positioning of the angle brackets will ensure a
tight fit without gaps between the brace and adjoining
sections
Fit the next corner brace at the correct height to make
fitting of the side bars easier.
Be aware the larger frame structure used with the
CT1700 has longer cross braces to increase support for
the longer side bars (not shown here)

Erecting the Frame structure
With the end goal posts and side bars assembled and laid out as shown here you are ready to begin
erecting the frame. Minimise the need to move the assembled frame structure by erecting it in the
final location of the clean tent. This process will require a minimum of two people, each with a step
ladder and 4mm hex key
With a person either side of one of the end goal posts, carefully both lift the goal post and side bars
together. Slide the union connections into the legs, tighten, then make the T-nut connections
between the corner brace and the side bars. Take care to ensure all these connections are correctly
made before carefully laying the frame down to rest. Pay attention to ensure the corner brace T-nuts
are fully rotated and secure.

Now both move to the other end, with the aid of a step ladder and 4mm hex key, carefully both lift
the other goal post and part assembled frame together. Slide the union connections into the T-slot
section of the vertical legs, tighten, then make the T-nut connections between the corner brace and
the long horizontal side bars. Take care to ensure all these connections are correctly aligned and pay
close attention to ensure the corner brace T-nuts are fully rotated and secure.

Using Clean Tent
Getting in and out of the tent
Note –The section below is intended as a typical working practice suggestion only and does not
constitute specific working practice guidance which may not be suitable for your application. It is
advised and expected that the user will carry out independent risk-assessments and working practice
guidance assessments prior to utilising the cleanroom.
Where possible, do not carry equipment in –have it passed to you
Only allow one person into or out of the tent at any one time unless there is an emergency.
•Fully open the zip.
•Part the opening with both hands.
•Look at the floor inside the tent. Lift and then place your leading foot inside.
•Transfer your weight to this foot.
•Lift and then place the trailing foot inside.
•Turn around and close the zip to the exhaust position.
•The tent will then re-inflate the gowning chamber to maximum.
Note - The tent is not designed to be structural i.e. personnel cannot use the tent to lean against
for support as they get in and out. The tent will start to slowly deflate whilst the entry zipper is
fully opened but will re-inflate once the zip is returned to the exhaust position.
Gowning room layout
There are 2 entry / exit zips in both the end wall and the bulkhead wall of the tent. This is designed
so that the user has 2 options to get into the tent if, for example, there was an external obstruction
to one zipper door e.g., a column.
Decide which entry zipper you will use.
After entering the tent through this zipper, you are in the “black “area of the Clean Tent
A small step over bench can be placed in the middle of the gowning chamber to effectively create
two halves of the chamber. The other side of the step over bench is in the “grey” area of the Clean
Tent.
The chamber where the HEPA filtered air enters is known as the “Cleanroom”.
A small coat stand can be placed in the black area. Here personnel can change into/ out of clean
room clothing.
Personnel should always move from outside to black then grey then into the cleanroom which is the
white area. The procedure is reversed for exiting.
WARNING It is possible to go from outside to the grey area if the wrong zipper is opened from
outside, similarly from white to black on exit. All users should be aware that this possibly breaks
protocol and should be avoided.

Getting equipment into the Work Cabin
We strongly recommend that heavy / bulky equipment is not taken through the gowning chamber. It
is better to break the protocol and put the equipment directly into the cleanroom. To do this the
floor zipper has to be opened.
Turn off the fan. Allow the tent to deflate and come onto the bungee safety cord. Unzip the
perimeter and bulkhead zippers. Lift the tent walls up on one side and using the tapes on the bottom
section of the Clean Tent corners, tie off to the cross-member of the pole structure or ceiling point.
Place a small ramp set on either side of the groundsheet zipper if equipment is to be wheeled in, this
protects the zipper from damage.
Once the equipment is in, assemble the tent per the install instructions and proceed to the
Housekeeping in the maintenance section of this manual for clean down procedures.
Services into the work cabin
It is very easy to add services to the Clean Tent. There are two options to entry: at the zipper joint in
the corner of the FFU end wall or via a through wall gland. There are many different options but here
are a few examples:
Power Place an extension cable though the zip joint.
Water If for cooling of equipment we recommend a closed loop chiller, externally sited with hoses
led through the zip joint. If mains is required, it is advised to use reinforced hose. Drain via PVC
waste through the zip joint.
Air conditioning Ensure that the unit air intake is from inside the cabin and place the unit in the
cleanroom with the heat dump tube outside to ambient via the zip joint.
If the user needs to retro fit a through wall gland, please get in touch with your Monmouth Scientific
or your agent.
