Check after Installation
Mechanical Check
Having completed the installation the unit is to be checked for any mechanical damages. Remainders of the
packaging material and dust in or on the unit must be removed.
Check the following:
- leakproofness of the water connections (including heat exchanger connections),
- the insulation of all cold water carrying components to the heat exchanger for damage,
- the condensate drainage (optional) for clear passage and sufficient slope,
- the fixing screws for proper fit,
- the suspension for rigidity and sufficient load--bearing capacity (ceiling units),
- the unit for not contacting the facade and the raw floor except via the seals provided and the supporting feet
(floor units),
- the line voltage and frequency to match the data given on the type plate,
- the electrical connections for proper execution and conformity to pertinent regulations,
- proper functioning of the control (optional),
- proper functioning of the motors (fan, actuators) without friction noises,
- the unit’s fixation,
- the diffusion area/diffusion grille of the unit to be free of any obstructions,
- proper horizontal alignment, accurate to dimension,
- sufficient water hose lengths and strainless laying,
Check for Media Supply
- Check for proper availability of primary air, cold water, warm water, and electrical power or compressed
air for the control.
- Check whether voltage and line frequency comply with the data given on the actuator’s type plate. Never
operate control devices with inappropriate voltage or frequency since this might result in destruction of the
units and put people at risk.
Control Technical Equipment
Supply of control devices by LTG Aktiengesellschaft is optional, however it is the rule for actuators for units
with dampers. Control valves are often factory--mounted.
Check for Proper Functioning
Turn the temperature control’s selection knob slowly from one end position to the other while keeping an eye
on the control dampers and linkage or the valves. Dampers and valves must move correspondingly quite
smoothly and without rattling noises from one end position to the other. No exceptional noise must be produ-
ced by the electric actuators. In case the units show damages have them properly repaired by an expert. Dam-
per linkages have been gauge adjusted in the factory and, therefore, require LTG Aktiengesellschaft’s skilled
personnel for readjustment.
Starting Standard Operation
Then set the temperature controller to the desired temperature. After a certain time the indoor air temperature
should meet the setpoint.
