Safety recommendations  
Reception in all countries except  
France:  
To avoid death, injury, equipment or  
property damage, the following  
recommendations should be  
observed during maintenance and  
service visits:  
1. The maximum allowable  
pressures for system leak testing  
on low and high pressure side  
are given in the chapter  
YKD/YKH units are designed to  
operate In cooling mode and  
equipped with a gas fired heating  
module.  
In case of concealed damage:The  
consignee (or the site  
representative) must send a  
registered letter to the last carrier  
within 7 days of delivery, claiming  
for the described damage. A copy of  
this letter must be sent toTrane

"Installation". Always provide a  
pressure regulator.  
2. Disconnect the main power  
supply before any servicing on

General information  
Warranty  
Refrigerant  
Storage  
Warranty is based on the general  
terms and conditions of the  
manufacturer.The warranty is void if  
the equipment is repaired or  
The refrigerant provided by the  
manufacturer meets all the  
Take precautions to prevent  
condensate formation inside the  
unit's electrical components and

requirements of our units. When  
using recycled or reprocessed  
refrigerant, it is advisable to ensure  
its quality is equivalent to that of a  
new refrigerant. For this, it is  
necessary to have a precise analysis  
made by a specialized laboratory. If  
this condition is not respected, the  
manufacturer warranty could be  
cancelled.  
modified without the written  
approval of the manufacturer, if the  
operating limits are exceeded or if  
the control system or the electrical  
wiring is modified. Damage due to  
misuse, lack of maintenance or  
failure to comply with the  
manufacturer's instructions or  
recommendations is not covered by  
the warranty obligation. If the user  
does not conform to the rules of  
this manual, it may entail  
Isolate all side panel service  
entrances and base pan openings  
(e.g., conduit holes, S/A and R/A  
openings, and flue openings) to  
minimize ambient air from entering  
the unit until it is ready for start-up.  
Maintenance contract  
It is strongly recommended that you  
sign a maintenance contract with  
your local Service Agency.This  
contract provides regular  
maintenance of your installation by  
a specialist in our equipment.  
Regular maintenance ensures that  
any malfunction is detected and  
corrected in good time and  
minimizes the possibility that  
serious damage will occur. Finally,  
regular maintenance ensures the  
maximum operating life of your  
equipment. We would remind you  
that failure to respect these  
installation and maintenance  
instructions may result in  
cancellation of warranty and  
liabilities by the manufacturer.  
Do not use the unit's heater as  
temporary heat without completing  
the start-up procedures detailed  
under "Unit Start-Up".  
TheTrane Company will not assume  
responsibility for equipment  
damage resulting from  
accumulation of condensate on the  
unit electrical components.  
Training  
To assist you in obtaining the best  
use of it and maintaining it in  
perfect operating condition over a  
long period of time, the  
manufacturer has at your disposal a  
refrigeration and air conditioning  
service school.The principal aim of  
this is to give operators and  
immediate cancellation of the  
warranty.  
technicians a better knowledge of  
the equipment they are using, or  
that is under their charge. Emphasis  
is particularly given to the  
importance of periodic checks on  
the unit operating parameters as  
well as on preventive maintenance,  
which reduces the cost of owning  
the unit by avoiding serious and  
costly breakdown.

Installation  
General information :The  
installation must conform to all  
local standards and regulations.  
There are two ways to handle the  
unit:  
1. Use the openings in the wooden  
frame to handle the machine  
using a fork lift, in accordance  
with applicable safety  
Reception of units  
Rooftop unit  
regulations.  
The unit is supplied on a wooden  
frame. It is recommended to check  
the machine's condition upon  
reception.  
2. Use a lifting beam correctly  
adjusted to fit the unit  
(Figure 1a).  
Unit handling  
The units are supplied on the truck  
but are not unloaded. An opening is  
provided on each corner of the unit  
base to facilitate handling.  
4 shackles and 4 slings are required.  
Use a lifting beam to prevent the  
cables pressing too hard on top of  
the unit during lifting.  
Figure 1a indicates the position of  
the center of gravity and the lifting  
recommendations.  
Important: For unit to fit on the  
roof curb the fork lift pockets must  
be removed.

Roof curbs are available as an  
accessory for "downflow" units to  
support the unit and ensure the  
water tightness between the rooftop  
and the roof.Two types of roof  
curbs are available:The standard  
version to allow the installation of  
the unit on a flat roof and the  
adjustable version for a sloped roof  
installation. (See Figure 1b for the  
maximum slope correction of  
adjustable roofcurb.)

Figure 1b - Maximum slope correction of adjustable roof curb.  
The adjustable roof curbs are  
supplied pre-assembled on a skid.  
Two types of self-adhesive seals are  
provided separately. (40 mm wide  
for the perimeter, 20 mm wide for  
the cross pieces). Make sure they  
are properly installed where  
indicated to assure an adequate  
curb to unit seal.  
Instructions for the roof curb  
assembly and installation with curb  
dimensions are provided with each  
roof curb kit.
