A water/glycol mixture should always be used when there is a risk of frost.
After use (end of rental period) blow through the heater with compressed air to remove any remaining
medium from the system in order to prevent freezing.
5.5. Cooling battery
A three-way cold water system is mounted on the front of the Compact Cool. This system ensures that the
desired air supply conditions of the unit are achieved.
The three-way mixing system is suitable for water as a water/glycol mixture. This can be either hot or cold.
The flow rate can be regulated by means of valves via the unit control system.
CAUTION!
A water/glycol mixture should always be used when there is a risk of frost.
The three-way mixing valve of the cooling battery is controlled by PLC.
5.5.1. Maintenance 5.4 & 5.5
The cooling coil front (inlet) unit can be reached by removing the filters. You should check the coil annually
for contaminants, and clean the coil if necessary using a high pressure water jet or compressed air, avoiding
damage to the fins. Repair any damage with a so-called 'Fin comb'.
When servicing coils, be aware of the hazards of the medium used; a neutral temperature is desired and the
medium must be sufficiently cooled. Even after switching off the heater (or cooler), the coil may remain hot
(or cold) for some time.
CAUTION!
When disconnecting both the coil and the defrosting heater, the coil must be drained on the
water side or stored frost-free.
5.6. Drip tray
The drip tray below the cooler collects the condensation water that runs off the cooler, including dirt.

Version 5.2_2021 (10 Juli 2021) 11
5.6.1. Drip tray maintenance
Dirt, possibly including substances of a biological or microbiological nature, collects in the drip trays of
coolers. These substances may pose a threat to health. Therefore, be careful when cleaning these drip
trays. The drip tray under the cooler must be checked for dirt and cleaned if necessary.
5.7. Droplet eliminator/separator
The droplet eliminator is mounted at the end of the drip tray to keep condensation away from the cooling
element. The droplet eliminator guides this to the drip tray.
5.7.1. Droplet eliminator maintenance
Check the droplet eliminator for contamination every six months, dismantle and clean if necessary.
5.8. Siphon
The draining of condensation (drip-tray) must be carried out using the siphon provided. This siphon serves

7. Control Technology
Components for control technology are integrated into the Compact Cool. The control strategy is determined
by selecting cooling or heating via the software.
For control technology, please refer to the user manual supplied with the product, which can also be found on
our website www.oc-verhulst.nl.
In OC Verhulst units that are frequency-controlled or equipped with EC technology, residual current devices,
neutral grounding can be used as extra protection, provided that local safety regulations are observed. A
grounding fault can cause a direct current in the discharge current. Do not use type A residual current devices
as they are not suitable for DC leakage currents. If residual current devices are used, they must comply with
local regulations. The residual current devices used must be suitable for protecting a unit with a direct current
(DC) in the grounding leakage flow (3-phase DC bridge). In addition, they must be suitable for a high leakage
current and for a short discharge current when switched on.
7.1. Air inlet temperature sensor:
Temperature sensor is mounted in the space between outdoor air inlet dampers and filters.
7.2. Supply air temperature (internal/external) sensor:
The internal temperature sensor is mounted in the space between the fans and supply dampers. It is also
possible to connect an external temperature sensor via a connection outside the cabinet. When this is
connected, the control strategy automatically changes to external temperature sensor.
7.3. Fluid supply / return temperature sensor:
For flow control, a temperature sensor is mounted on the supply and return lines of the coil.
7.4. Dual position switch (start/stop):
The fans and the three-way valve can be switched on or off via the dual position switch. Optionally, it is
possible to control the unit with a time schedule (see defrosting cycle).
7.5. Control panel:
Everything can be set via the control panel. The main screen contains the most important data. Fan speed,
three-way valve control and temperature setpoint.
7.6. Fans:
The fans are controlled via a potentiometer (0-100%) and a dual position switch stop /start). The controller
translates this to the EC fan via ModBus and is controlled by it.
7.7. Three-way valve:
The valve is controlled via 0-10V. The control is based on a PI control with setpoint and supply air
temperature or room temperature.

Version 5.2_2021 (10 Juli 2021) 18
7.8. Defrosting cycle:
Defrosting cycle is started manually via a push button. The first time the button is pressed, the defrosting
cycle of 10 minutes starts. After each press, 10 minutes are added. The time can be read from the display.
Pressing the push button for 5 seconds resets the defrosting cycle and restarts the standard control strategy.
During the defrosting cycle, the fan is reduced to a percentage of the speed set in the controller.
The defrosting cycle can also be set as a time schedule. Via the display, an ending time and eight different
start times can be set. The unit will then switch on at the set time and run for the set duration. It switches off
automatically (after the duration) and on again at the next set time.
7.9. tERA Portal:
A tERA portal can be connected to the Carel controller. The tERA portal is a GPRS box that allows you to
read and operate everything remotely. It is also possible to log (graphs, tables).

8. Set-up and installation
! CAUTION:
This chapter contains important instructions on how to safely install your Compact Cool!
8.1. Preparations
The following preparations are important for setting up the Compact Cool:
- The unit is designed for both indoor and outdoor installation.
- The Compact Cool should be placed on a stable surface.
- The set-up must be designed in such a way that there is sufficient space around the unit for
inspection and service work. The need to work safely must be borne in mind. This requires a
clearance of at least 1 metre on the inspection side. Moreover, free space is necessary for
unimpeded air supply and extraction. Attention must be paid to prevent an air short circuit between
the air injection and intake. The intake of fresh outside air must be taken into account (no exhaust
fans or other exhaust openings in the immediate vicinity of the air intake opening).
- The foundation must be such that the unit can be set up level, with the load sufficiently supported,
and vibration transmission minimised.
Safety!
- Before the Compact Cool can be put into operation, all inlet and outlet openings must be fitted with
ducts or grilles. All inspection doors / hatches must be closed. This is to prevent physical injury.
! CAUTION:
To ensure that the unit functions properly, it must be set up completely level (height should
be compensated with shims under the unit or vibration dampers).
If you have any questions or doubts about the set-up options, please contact OC Verhulst.
Information on dimensions and weights is given in the technical data mentioned above and on the scale
drawing of your unit.
8.2. Delivery and transport
We advise you to check your Compact Cool immediately upon delivery by OC Verhulst for transport damage.
Report any transport damage immediately to the carrier and within 24 hours to OC Verhulst. If transport
damage is not reported immediately, all warranty claims become null and void.
Also check that the delivery is complete (see the packing list) and that the necessary documentation is
present (in the control compartment).
8.2.1. Vertical transport
When transporting to the installation site, please ensure that the transport and lifting instructions shown in
the drawings below are followed. The unit must be moved using appropriate lifting gear.
When lifting the air handling unit, the lifting eyes at the top of the unit must be used. The hoisting strap must
be attached to the crane hook with a bow shackle (4 pcs M16). Please note the stated weight!

Version 5.2_2021 (10 Juli 2021) 20
8.2.2. Horizontal transport
If the crane hooks are not used, use the fittings in the frame (so-called hoisting pockets). Use forklift prongs
with sufficient length. These should protrude through the frame. The use of chains is not recommended.
! CAUTION:
During transport by OC Verhulst, all openings as well as other connections are covered.
Leave this sealing intact for as long as possible to prevent dirt and moisture from entering
the unit.
All valves must be closed during transport by the rental company.
8.3. Temporary storage
If the Compact Cool cannot be set up immediately, all the medium and air openings must be temporarily
closed and all valves closed. If the Compact Cool is taken out of operation for a longer period of time, the
following points should be noted:
•The unit must be switched off properly (see chapter 9.1.
•All dampers and valves must be closed.
•If a glycol mixture is used, it must be drained off. This also applies to the cooler and defrosting
heater.
•It is possible to stack the units on top of each other. CAUTION maximum of 2 on top of each
other!
