All units leaving the McQuay plant are inspected for quality
prior to shipment.
Carefully inspect all shipments immediately upon delivery. Note
visible damage on the carrier’s freight bill and request that the
carrier send a representative to inspect the damage. This may
be completed by telephone or in person, but should always be
confirmed in writing.
The shipment should be unpacked in the presence of the agent
so that the extent of the damage or loss can be determined. The
carrier’s agent will make an inspection report and a copy will
be given to the consignee for forwarding to the carrier with a
formal claim.
Unit Installation
The unit is designed to be concealed in the ceiling. Installation
and maintenance should be performed by qualified personnel
who are familiar with local codes and regulations, and experi-
enced with this type of equipment.
There are holes on the top of the unit for hanging the unit above
the ceiling. Please refer to Figure 1. , Figure 2., and Figure 3.
NOTE: Vibration isolaters provided by others.
Before installation and running the unit, please check the
following:
1. There must be enough space for the unit installation
and maintenance. Please refer to the unit outline and
dimensions in Figure 1 for the minimum distance
between the unit and obstacles.
2. Mount with the lowest moving parts at least 8 feet above
the floor or grade level.
3. Ensure enough space for piping connection and
electrical wiring.
4. Leave a means for disconnection from the electrical
supply according to NEC or local codes.
5. Check whether the hanging rods can support the weight
of the unit.
6. The unit must be installed horizontally for proper
operation and condensate draining.
7. The external static pressure must be within the
allowable static pressure range.
8. The installing contractor must supply service valves and
insulation for water piping in accordance with local codes
and regulations.
9. To prevent strain on the wire connections, use either
conduit or approved strain relief device.
10. Confirm that the power has been switched OFF before
installing or servicing the unit.
Make sure the top of the unit is level after installation. The
drain pan is designed with a little gradient to facilitate
drainage. Do Not Level Drain Pan!
