CAUTION
A manufactured (mobile) home installation must
conform with the Manufactured Home
Construction and Safety Standard, Title 24
CFR, Part 3280, or when this Standard is not
applicable, the Standard for Manufactured
Home Installations (Manufactured Home Sites,
Communities and Set-Ups), ANSI/NCS A225.1,
and/or MH Series Mobile Homes, CAN/CSA
Z240.
CAUTION
Before lifting, make sure the unit weight is
distributed equally on the rigging
cables so it will lift evenly.
CAUTION
All panels must be secured in place when the
unit is lifted.
The condenser coils should be protected form
rigging cable damage with plywood or other
suitable material.
2 INSTALLATION
1.1 Inspection
1.2 Limitations
2.1 Pre-Installation
2.2 Clearance
2.3 Rigging and Handing
As soon as unit is received, it should be inspected and
noted for possible shipping damage during transportation.
It is carrier’s responsibility to cover the cost of shipping
damage. Manufacturer or distributor will not accept the
claims from dealer for any transportation damage.
Refer to Fig. 2-2, 2-3 , 2-4, 2-5 for unit physical data and
to Table 6-1 & 6-2 for electrical data.If components are
to be added to a unit they must meet local codes, they
are to be installed at the dealer’s and /or the customer’s
expense.
Size of unit for proposed installation should be based on
heat loss / heat gain calculations made in accordance
with industry recognized procedures identified by the Air
Conditioning Contractors of America.
Before installation, carefully check the following:
1. Unit should be installed in accordance with national
and local safety codes, including but not limit to
ANSI/NFPS No. 70 or Canadian Electrical Code Part 1,
C22.1, local plumbing and wastewater codes and any
other applicable codes.
2. For rooftop installation, be sure the structure has
enough strength to support the weight of unit. Unit
should be installed on roof curb and leveled.
3. For ground level installation, a level slab should be
used.
4. Condenser airflow should not be restricted.
5. On applications when a roof curb is used, the unit
must be positioned on the curb so the front of the unit is
tight against the curb.
All units require certain clearance for proper operation
and service. Refer to Table 2-1 for the clearances
required for construction, servicing and proper unit
operation.
Exercise care when moving the unit. Do not remove any
packaging until the unit is near the place of installation.
Rig the unit by attaching chain or cable slings to the
lifting holes provided in the base rails. Spreader bars,
whose length exceeds the largest dimension across the
unit, MUST be used across the top of the unit.
Units may be moved or lifted with a forklift. Slotted
openings in the base rails are provided for this purpose.
Check the electric wire, water and gas pipeline
layout inside the wall, floor and ceiling before
installation. Do not implement drilling unless
confirm safety with the user, especially for the
hidden power wire. An electroprobe can be used
to test whether a wire is passing by at the drilling
location, to prevent physical injury or death
caused by insulation broken cords.
WARNING
Check the power supply before installation.
Ensure that the power supply must be reliably
grounded following local, state and National
Electrical Codes. If not, for example, if the
ground wire is detected charged, installation is
prohibited before it is rectified. Otherwise, there
is a risk of fire and electric shock, causing
physical injury or death.
