Dear garden friend,
Congratulations for the purchase of an aluminum greenhouse from Hoklartherm.
The erection is simple. First read the mounting instruction and follow this step by step.
Parts and piece list
Start with the basic kit (please do not open all the boxes at the same time) and do not
confuse about the numerous single parts.
Before you start with the assembly please check with the piece list, if all the parts are there.
Every box is checked by a quality control before closing it and consequently missing parts
can nearly be excluded. Should there be any lacking parts, please state the mistake in
position.
Location
Please choose, as far as possible, a sunny place for your greenhouse. Avoid the shadow
of buildings and trees. For vegetables like tomatoes, cucumbers and melons you have to
place your greenhouse in the Northern-Southern direction. For owers and pot plants it is the
Eastern-Western direction.
Attention:
If possible, the greenhouse should be set up at a wind-protected place and not in
stormy weather. It is dangerous to have stand a partly assembled house.
An assembly according to the rules lets resist this greenhouse heavy wind. The manufacturer
is not responsible for any damages being arisen by improper assembly or acts of God!
The assembly must be executed by at least two persons!
Work with safe, proper tools and be careful for a secure standing of the ladder during the
assembly (danger of accident).
Do only work with gloves (danger of injury, danger of cutting)!
For the assembly you need the following tools:
1 pc screwdriver for recessed-head screws, size 2
1 pc open-jawed wrench 10 mm
1 pc screwdriver for slotted screws
1 pc Allan key 3 mm (in the bag of accessories for skylight)
1 pc water level
1 pc ladder
1 pc le to remove possible burs at the proless
1 pc rubber hammer
1 pc measuring tape

Good advice for a quick and perfect assembly of the greenhouse from Hoklartherm
Most of the assembly can be done by you alone. The assembly for gable and lateral walls takes 2 – 4
hours according to your skills. It is best if you have further two persons being able to hold it for approx.
half an hour when putting the greenhouse upright.
If you want to go on mounting it alone you have to look for a secure, suitable mounting course by means
of stay bars, ladder or other xings.
Unlike the most usual greenhouses, the mounting of the aluminum proles is done together with
the glazing. This results into an absolutely secure glazing and the biggest possible stability of the
greenhouse.
You obtained 3 to 5 boxes depending on the greenhouse.
1 x basic kit → contents see p. 6 + 7
1 x windows and doors → contents see p. 8 – 11
1 x glazing (for bigger houses 2 boxes)
Please stay all the boxes in a dry place and protected against sunlight (see note below).
Please rst open and unpack only the main box with the basic kit to avoid a mixing of the many different
parts.
Please start with the assembly of the greenhouse gables. Door wall gable and back wall gable are
nearly the same.
Push the prole of the frame of doors pos. 1.6 –right- and pos. 1.7 –left- (prole with 8 borings with a
slope of 30° as well as a black PVC-glider) up to the smaller borings in the centre of the oor prole.
The slopes there have to point to the outside direction. Then detach the angle brackets pos. 1 (see step
1).
Already now you need the small lateral glazing (measurements see table*). Push it with the web
direction – vertical – into the oor prole and push laterally into the prole of the frame of doors (see
step 2).
Important note:
The ISO-cellular sheets, that is the glazing, are always to build in with the UV-coated side to the outside.
On the protection foil you nd a corresponding note or a blue foil. Loosen the protection foils only at the
edge and the complete rest of the foil only after the nished assembly . With some days of insolation
the foil can burn "tight" on the plates and is to stripe off with difculty.
Do not stripe it completely off when unpacking the goods because then you cannot see the side with
the UV-protection.
Now detach the crossbeam pos. 1.9 from the top onto the glazing (see step 3). Then the beveled glazing
is to put in the same way. Joint the frame of doors with the connection plate pos. 2 (see step 4).
Attention!
In advance 2 screws have to be screwed in both vertical frames of doors and 2 screws into the
horizontal frame of doors.

On the square head of the angle bracket you detach the edge stay bars pos. 1.2 + pos. 1.3
(length 1447 mm). Take care that the groove is on the top! Do not position any triangular
glazing onto the frame of doors.
The verge ashing proles in pos. 1.4 and 1.5 must be detached onto the slopes and be
joined together with the prole of the frame of doors by means of a trapezoid clamping plate.
At the verge ashing prole with two sheet metal screws 4,2 x 13, at the prole of the frame
of doors with M6 x 12 (see step 4 + 5).
Screw down the crossbeam by means of sheet metal screws 4,8 x 45 (see step 6).
Note 1: If the proles have any PVC-gliders you can still later push in the required screws through the
opening of the PVC-glider!
Note 2: One verge ashing prole (pos. 1.3.3.) has two small openings for the xing of the door
locking device, thus you have to determine now where the door should be mounted.
The back wall gable is to assemble the same way. Please build in one crossbeam in pos. 1.8 (length
758 mm) exactly in the height of the already existing crossbeams. Fix with the rectangular connector 35
x 90 with 3 borings (see step 7).
Attention! Here you put in the glazing 787 x 728 mm before! The above remaining opening will be
closed later by the intended standard back wall window.
Assembly of the lateral and roof segments ( see steps 8 - 15)
Now you need some more assistance or corresponding aids!
Set the gable upright, hold it or support it safely (see step 8).
At rst the lateral oor proles (measurement see table*) are
to detach on the angle bracket of the gable (see step 8).
The ridge prole is now to introduce into the existing nuts
/ slots of the gable that the prole is ush in the front. Now
screw together with the ridge / grooved end plate by means
of sheet metal screws 4,2 x 13 (see step 9 ).
A lateral glazing is to push into the oor prole and the edge
prole. It is best, if at both sides. Thus the gable stands safely (see step 10).
The next is to push in a pane of the skylight glazing into the grooved prole and into the verge ashing
prole. Introduce roof stay bars into the grooved prole and eaves prole and push up until the glazing
(thread-up glazing). The remaining panes are to complete.
Please determine the position of the window in time!
Here put in the short pane of the skylight glazing and close with the window crossbeam pos. 3.2. The
round connection plates have to be used to screw (see step 12).

Now the second gable in the foot is to connect with the oor lengthwise prole in the same way already
known. Push the grooved prole and ridge prole into the nuts / slots of the gable proles. Screw down
as well with the grooved and ridge end plates.
Now a small angle 30/30/20 x 2 can be screwed in by means of sheet metal screws 4,2 x 16 to secure
the oor proles (see step 15). If you use a foundation frame this angle not urgently necessary, as the
foundation frame has an L-connection (see p. 13).
The stabilizing / edge angles (pos.3.4) are to x at the edge stay bars and lateral stay bars by means of
srews M6x16 and plain washers. These have a stabilizing effect and give a protection of the greenhouse
against stormy weather. At the same time these angles are the back wall proles for the tables and
shelves (see separate mounting instruction).
Now the skeletal structure is nished – topping-out ceremony is the order of the day!
Please open now the accessories box. Here you nd:
1 pc skylight including automatic window opener contents see p. 8
1 pc divided revolving door contents see p. 9 + 10
1 pc back wall window contents see p. 11
These parts are to mount according to the instructions (see p. 8 – 11).
Doors and back wall window can be mounted at both gables. Borings for the door hinges / bands exist
in every right prole of frames of doors. However, please take care that we have intended the borings
for the door locking device at only one verge ashing prole (see step 5). Should you mount the door
on the other side, the corresponding borings have to be transferred then.
The skylight is to push from the lateral into the ridge (see step 15). This system is generally very
simple and explains itself.
Further useful notes:
Erection with a foundation frame:
This is the simplest but also the securest erection of a greenhouse. The foundation frame is hooked
non-positively into the oor prole of the greenhouse and screwed down in the edges by an angle
bracket (see p. 13).
It is best and easiest to assemble the foundation frame together with the greenhouse! But this is
also possible later – without any energy. Then you only must lift the greenhouse (it is best to do this at
one side) and laterally hook in the foundation frame into the oor prole.
Erection with the foundation frame:
At rst you have to dig a small ditch, cut of the spade approx. 10 – 12 cm deep, according to the
given measurements of the foundation frame. In each of the four corners you horizontally place a
cobblestone as a support for an exact level compensation. This avoids a possible sinking of the
greenhouse. Then the greenhouse with the foundation frame is to put in this ditch and the foundation
frame is to ll by the excavated material. It is useful to lay down there some garden plates or
agstones in order to avoid any dirty splashes at the greenhouse due to strong rain. Besides, working
around the greenhouse is simpler, e.g. mowing the lawn.

Question: Is it necessary to „seal“ the greenhouse or greenhouse glazing respectively ?
Principally: not.
However, we recommend to seal the horizontal transitions from the glazing to the prole (see sketch
→ broken lines ---) with neutrally linking, transparent silicon in order to have the most possible small
amount of water and thus little dirt in the glazing reception.
Advantage: In the long term the greenhouse has a better appearance. The tendency to the algae
formation just in this area decreases
tremendously.
Humidity / water can also appear
within the glazing/cellular sheets
according to the weather situation
because the PVC-sheets are not
"steam-diffusion-tight", that means
that humidity in the form of steam
penetrates into the sheet. This is a
purely optical disadvantage which
cannot be avoided.
The sheets cannot suffer any damage, even not with frosty days.
Attention: Use only „neutrally linking“ silicon due to possible stress
cracks in the PVC-glazing. This is
the most common silicon sealant being available with any DIY superstore or with your
Hoklartherm expert dealer priced at 4 – 6 € / 310 mm cartridge.
Cleansing and maintenance:
Clean the greenhouse with much water only (for ex.: with a car wash-brush or a HP-cleaning apparatus.
You can additionally use any puriers.
We wish all the buyers and users of this Hoklartherm-greenhouse much fun with their hobby
of gardening and have much success with growth!
